Tea Urchin 2019 LaoManE 

It started out very fluffy and nondescript, and kept that throughout the session, and there’s a strong astringency throughout. However, underneath those there’s a fairly cohesive quality, although it lacks a solid present weight. It’s as if the astringency breaks apart the “ball” of tea that would be there. The astringency is good quality, but way too much. Anyway, underneath all of this is the beautiful citrus-spice flavor, with less bitterness than expected. So… where’s this astringency from? Signs point to potassium, as it’s very common for it to cause astringency, but natural waters with potassium don’t have such a severe effect. They also have different compositions, though. 

The body of the tea is really nice, as well as the residual oils. The throat/bitterness is not great, though. It’s too candied and mild, I’d prefer some deeper yun and stronger bitterness from this tea. Why is the bitterness so low? There’s plenty of sulfate, so it should be high. My only explanation would be an excess of bicarbonate due to a measurement or calculation error. The bicarbonate could be eating up the bitterness and potency. The last possibility is the zerowater pitcher making the water alkaline due to trace NaOH. This would be solved by purchasing a good RO filter.

I came back to water chemistry recently because I’ve been watching so many chemistry videos on YouTube – I realized that although the chemistry in mineralizing water is fairly simple, the work itself, the trial and error, and the problem solving is very deep and interesting. Hearing stories from research chemists made me feel like I’m in the same boat – trying to accomplish a goal and trying different ways to get there, with no idea when you’ll find the solution. 

2012 TU the orchid in valley

Really highlights the woody aspects. Initial taste was not a good experience but it grew to be more engaging with high quality rear tastes and deep flavors with a little heat and acidity too. Very pencil shavings-y. A bit juicy, which is nice. Could be 3x more though. Astringency medium. 

2017 YS wild jinggu 

Water diluted to 3/4 strength

Immediately smoother, round, still has a weird bitter co2 taste maybe? But a beautiful presentation. It sort of tightens into a slightly astringent finish when I’d like it to expand on release. Overall a nice session.

Some encouraging results! These sessions will give me a direction forward for future water batches. I’m simply enjoying the exploration.

Water Recipe #4 “Complex Syrup” vs. NYC Tap Water

NOTE: The recipe was called Simple Syrup at the time of this review, and is now called Complex Syrup to reflect the complexity of the tea.

I just moved to NYC, which is famous for its tap water quality. I’m currently distilling water in glass behind me while writing this review, listening to techno and doing a side by side Tap vs Recipe water review. I’m pretty excited that I can do all this at once! I recently watched a James Hoffmann water for coffee video where he compared four water recipes without a control, and everyone in the comments was quite upset about it. So, I decided to review Arby’s (empiricaltea.com) new water recipe (which I helped a bit on) against a good, well-reputed tap water. Check out his post on it at https://empiricaltea.com/water-recipe-complex-syrup/ and try his 10x concentrate method, which lets you make a concentrate you can then use to make ten gallons! I just made one gallon this time, but it’s more accurate to use Arby’s method. Complex Syrup was designed to be more friendly to drink than Truth Serum, but will there still be flavor complexity? And how will it do against normal tap water? Let’s find out.

The Recipe:

(To purchase the materials you need, please visit the Water Guide.)

Short instructions: in one gallon of distilled or other 0 ppm TDS water, add each mineral one at a time. Carefully weigh each mineral on a milligram scale (not a regular gram scale) and make sure all of it has made it into the water and none is left stuck to the tray. Clean the tray between weighing each substance. Wait at least a minute between adding each mineral. When done, wait 20 minutes for the minerals to dissolve, shaking occasionally. If you have a different size container, use 1 gallon = 3.785 L to convert the amounts. For example, if you’re only making 1 liter, divide every amount by 3.785.

Tasting Procedure:

Side by side, small gaiwans, with a bland snack in between sessions.

Session 1: 2020 White2Tea Turtle Dove

3.6g/50ml gaiwan, 100ºC

Early impressions: Complex Syrup sips with thickness, smoothness, florals and caramels coming in after a watery start. NYC water much more watery, with less presence but more quiet subtle tastes. On the second steep, it’s clear that Complex Syrup is steeping darker and denser. Wet leaf aroma on NYC is sweet and light, while on CS it’s richer. Nyc session is on light, sweet hay, some oils. CS is on very complex, sweet fruit syrups, more oils, density. A little bit grippier, but no mouth drying, just some light tannins. These two parallel gaiwans are the same tea, but in the cup, they’re so different. The CS cup is more present – not more forward, just more taste overall. The NYC cup could be perceived as more refreshing.

Please be good water…

Mid-session: The CS cup has the clearest most vivid note of blueberries I’ve ever witnessed in a tea. The NYC tap is more subtle buttery sweet floral hay. A deep throatfeel is also present in CS. Aftertaste is more long-lasting. It’s much more dense, double IPA dense, but still in a full range of flavors. NYC Empty Cup Aroma (ECA) is better.

Long Late Steep: NYC sort of bitter, nice aftertaste of brown butter and various green raw vegetables. CS also bitter, but more concentrated, a bit more upfront, thickness, an evaporating quality, wood oils, syrups (haha), sort of this idea of flowers with muscles (strange). Pepper. Back to the NYC cup, a little bit more easy to drink, but the tannins dominate without much else to engage.

Ideally, the CS could be modified to be more refreshing while maintaining its complexity and delivery of flavors – but this is not simple, and as is, it was very very impressive and I enjoyed it more than NYC tap water for this tea.

Notice on the left, SS is slightly darker

NYC Session Rating: 6.8

CS Session Rating: 8

NYC Water rating for this tea: 7.5

CS Water rating for this tea: 8.4

Session 2: 2008 Tung Ting Yiwu Anniversary

Let’s try a Malaysia-stored aged Yiwu…

3.6g/50ml gaiwan, 100ºC

Early impressions: NYC slightly sour, light but with savoriness, slight smoke. CS savory, smoky, tart, richer. Much darker in color. CS has sweetness, sweet wood, sugariness underneath. NYC doesn’t have that same sweetness and instead has a thin herbal quality. Qi immediately – no way to know which cup it’s from. CS deeper and sweeter. Thick oils. NYC more refreshing, but I’m not sure that’s good for this tea. Perhaps more leaf would be necessary with NYC. Second steep of NYC is still weak and watery, starting to open up. It’s so much lighter. With CS, it’s full force. Perfect grippy tannins, yiwu sweet syrup, and all sorts of candied and wood flavors. CS makes it deliver like a whisky. Qi is definitely from CS, wiggly upward fluid sensation.

Mid-session: NYC strength starting to build, but there’s something weak and eggy about it. I filtered it through a good carbon filter, so it’s not from the water itself. With CS, I’m getting more information, conveyed well. Much better balance than Truth Serum. Present, sweet, clear wood-plum, not sour. NYC is reading sour, while CS is making it not sour. I think, perhaps the increased sweetness in CS is balancing it out.

Long Late Steep: NYC very oily, sweetness and dark fruits coming through, strong woody tannins. Not a ton of tertiary notes coming through – simple. CS very strong. Huigan, fruity, bursting with citrus peels/furniture polish. It’s clear here that there’s more in CS.

NYC Session Rating: 6.9

CS Session Rating: 8.2

NYC Water rating for this tea: 5.8

CS Water rating for this tea: 8.8

Overall impressions:

Wow. The catchphrase for Complex Syrup should be “get more out of your tea” because that’s exactly what I got during this review. I didn’t even think the NYC water was flawed, but then again, I started making recipes in NYC because I wasn’t getting enough of an experience from the tap water. The side by side brought great perspective to just how much more flavor you get out of a well-tuned, well-designed recipe like CS. The mouthfeel was also great, and even when I oversteeped I wasn’t punished for it like I was with Truth Serum sometimes. Truth Serum is good as a tool, but Complex Syrup brings great enjoyment, with vivid, bursting notes across the flavor spectrum.

By the way, NYC water changes all the time, so it’s quite difficult to get good data on it. However, the conductivity was 104 μS/cm. This is about 70 TDS.

Average NYC session rating: 6.85/10

Average CS session rating: 8.1/10

NYC Water rating: 6.7/10

CS Water rating: 8.6/10

Replicating Water from the Xi River and Making Tea With It

I’ve been wanting to try Chinese tea with Chinese water for a long time, because it would be so cool, but only recently did I stumble upon some good data that I could use to replicate Chinese water at home. This water is a replica of the Xi River in winter (seasonal variation in natural water is significant, as TDS changes around 50% from winter to summer.) The main branch of the Xi River is located west of Guangzhou, but the basin of the river extends all the way to Kunming, in Yunnan. This water is rather difficult to make, and can not be made without a Sodastream. I used a new method to get silica into the water, and decided to test the new method by adding double the silica that was in the data. I don’t think it should make too much of a difference, but I wanted to note it here. Silica is not an ion, so it doesn’t have as significant an effect on extraction, only on texture (as far as I know now!)

After a lot of work over two weeks, here it is.

2750 ml

The water was distilled from my local tap water, which recently tested over the safe limit for PFAs, a pollutant that can cause health problems. I get a kick out of removing pollution from water by purifying it – distilling water removes PFAs entirely, and I distilled this water three times. Two of these distillations were in glass laboratory equipment dedicated to water. This resulted in my base water being some of the cleanest and purest I’ve managed to create, with the downside being 10 hours of distillation time to get only 2750 ml. I’m sure I can cut that time down in the future. I’m just really happy I can get pure tasting water at all, as it was a big struggle just a year ago. The distilled can go side by side with lofoten and hold its own! It’s not perfect by any means, but it is around the same level as very good natural waters bottled in glass.

Once I had this base water, I had to add the minerals to it. It wasn’t too difficult really, and took around an hour and a half to get everything measured and added properly. I’ve shared the water with friends and family and they’ve remarked that it tastes like water, nothing is wrong with it, and it’s rather dry (not drying, but referring to not too sweet). I suppose that is a success as water is concerned, though I’d love to make water that makes you go “wow!” I personally find the water quite voluminous in a nice way, but we will get to that later. The big curiosity is, does using (replicated) Chinese water “work” with tea grown near it? Does it express the taste as nature intended? Let’s find out.

Testing the Water with Tea: White2Tea 2016 The Treachery of Storytelling Pt. 2

6.3g/100ml

I chose Treachery because it’s a tea that demands good water, all about power and subtlety, in an interesting stage of aging, just beginning to darken in leaf color. It demands a water that can bring out both the youthful and aging side of the tea. It also has an energy that I’d like to experience in a comfortable way throughout the session. Aside from those considerations, I’m open to any outcome here, as it would be interesting to see how water that may be similar in mineral profile to what the tea “drank” in order to grow will interact with the tea and the experience of it. I’m not sure that tea drinkers even use tap water in China, depending on the area, or if the tap water is not altered in mineral content from the river water, but it’s worth a try for curiosity’s sake.

The water hits the teapot, sending an immediate aroma of flowers and dried fruit upward. The rinse pours a pale straw yellow. Empty pitcher smells of sweets. The leaf in the pot is intensely fragrant, like sunscreen and leather.

After the first steep is poured, immediately scale is forming in the kettle. This water is rather heavy, so I expected this to happen. It is kind of strange how rapidly this occurs, but I think natural water of this heaviness would do the same thing.

The taste of the first steep – bitter. Watery. Smooth. Many subtleties immediately – I’m delighted! Oiliness focused on the front of the tongue, evaporating into many tiny flowers and fruit essences. This is the most clear this tea has ever tasted for me. A brilliant oily soapiness blooming into a rose flower aftertaste. ECA is mild.

Second steep – the mouthfeel is so very soft, the silica is making a huge difference. The tea sort of inflates in the mouth. Juicy. Qi hits here. Downward qi, clarifying. The wateriness persists, refreshing. Extremely smooth, a lot of rear activity, experience of drinking moving from front to back to front. Leather and tobacco fairly obvious here, but the body and watery quality make this steep seem almost crystalline.

The Pyrex pitcher has never been more relevant

Speaking of crystals, unfortunately there’s a colossal amount of scale forming unlike any I’ve ever seen, forming crystalline globs on the bottom of the kettle. Luckily they’re not actually stuck together, just powdery scale collected in various spots on the bottom of the kettle. I’m sure this is changing the mineral content quite a bit, removing calcium carbonate from the water. This scale looks different than usual, so it could be silica in the scale too.

Lots of scale.

Third steep was similar to second.

Fourth steep – great bubbles on the surface of the tea, meaning we haven’t lost too much bicarbonate to scaling. Beginning to be a more full-mouth-all-at-once-experience. Darker, deeper, tannins showing up. Something that reminds me of citrus, like deep tangerine, or bitter orange juice. Smoother than any water I’ve ever made by far. 30 ppm silica is a big difference. The water holds together nicely. Huge focused relaxed energy. In tune. Heating in back. Not very sweet, like a very dry orange wine (white wine with the skins kept on) or a wild ale. Big pollen huigan!!

Seriously.

Fifth – Under-lid aroma is flowery, in a settled way, not like a brand-new tea would be, balmy. The scale is not showing up in the cup at all, though, which is nice. I’m very happy right now, for many reasons – the base water is good, the tea is good, the mineral composition is natural, the result is somewhere in the liminal space between natural and… well, not artificial… what is this? I guess this water is a secret, nobody has ever tried it, let alone with tea, except maybe people in the Xijiang Basin have this running in their house all the time. That’s a secret from me, I’ve sort of taken this water out of context and placed it in a new context that reflects a reality that I’ve probably made up. Not the first time this has happened in tea culture. Please contact me if you know if this water is used by many people. I believe it is similar to Guangzhou tap water, which is taken from six tributaries of the Pearl river, and the Xi is one of the main tributaries. I’m aware of water pollution in china too, so if everyone uses bottled water, or if it’s a mix, I appreciate the info. Back to the session – I’m getting a woody-stemminess, and awesome petroleum power. The tea isn’t heavy though, it still floats and has structure.

Sixth – What is this water? I mean, when you have a beyond burger, it’s kind of natural, but it’s fairly obvious you’re having something that’s been built from something else. But with this, I distilled water, which is what nature does with clouds and rain. Then I added minerals, which is what happens when water flows over rocks. There are some things missing, like the volatile scents of rocks, which are a real thing, such as the many volatile compounds that cause the petrichor effect after it rains. But chemically, it’s nearly identical to natural water at this point. It’s more like a photograph, or a sculpture of nature.

artificial (adj.)
late 14c., “not natural or spontaneous,” from Old French artificial, from Latin artificialis “of or belonging to art,” from artificium “a work of art; skill; theory, system,” from artifex (genitive artificis) “craftsman, artist, master of an art” (music, acting, sculpting, etc.), from stem of ars “art” (see art (n.)) + -fex “maker,” from facere “to do, make” (from PIE root *dhe- “to set, put”).

Earliest use in English is in the phrase artificial day “part of the day from sunrise to sunset” (as opposed to the natural day of 24 hours). Meaning “made by man, contrived by human skill and labor” is from early 15c. The word was applied from 16c. to anything made in imitation of, or as a substitute for, what is natural, whether real (light, tears) or not (teeth, flowers). Meaning “fictitious, assumed, not genuine” is from 1640s; that of “full of affectation, insincere” is from 1590s. Artificial insemination dates from 1894. Artificial intelligence “the science and engineering of making intelligent machines” was coined in 1956.

Sixth (cont.) – present. Roots, like fennel, parsnip. Dry huigan, dry mouthcoat, but not drying. Dry in taste in every aspect. Rather elegantly dry. The idea of sweetness is still there though, thank goodness.

Seventh – a 45 second steep, lighter than expected, too short of a steep. Taste is fairly mild here. I’m surprised at the slow extraction. Still has dried raspberry, creamy, qi. While the next steep is happening, let me talk about the chemistry of this water. High in bicarbonate, calcium and sulfate, higher potassium than normal, medium-low sodium. Low in magnesium. The potassium and sulfate contribute to the dry flavor and depth. The low magnesium and high calcium create a smooth and settled profile, and may cause the slower extraction.

Eighth – 2 minutes, good color, more present. Still quite watery in a way, but I’ve heard of this tea being like this. It’s watery but not underextracted. There’s plenty to chew on here. Oats and grains, definitely. I love the purity of the base water, free from plastic. My body is refreshed, back sweating, butter and bubblegum aftertaste. The tea is always shifting, elusive. Foresty taste, dense deep mouthcoat.

Ninth – Ripe peach. Only noticed this obvious note now, the florals were so distracting earlier! Getting more and more ethereal, focused on aftertaste, so vivid. There’s something natural and microbiological about the tea, as if some sort of fermentation is happening in the cup, like wine. It’s not close to sour or anything, but complex and active, alive.

Tenth – I am out of water in the kettle, let’s see if a fresh boil will revitalize it. A smell in the glass water container confirms that this water is indeed odorless, which is great. Tenth steep, still from the first boil, same boil as the last nine steeps, is a bit flat, but still nice. Suntan lotion, banana, bubblegum, irises, corn. Mouth is happy, not dried out at all. Pleasantly coated in tannins.

Eleven – fresh boil, 3 minute steep. Actually not enormously different. A bit more vitality and strength. This session overall is very relaxed, yet bitter, watery, yet potent. I love a good paradox in a cup! Sessions with other waters have been sort of similar, but not as bitter. It’s much less bitter than, say, the Truth Serum water recipe would make this tea. Grape skins, red and white.

Twelve – Final steep, ten minutes. Still so smooth, mild, chewy. Tobacco, simmered root vegetables, oils, coconut. Such an endlessly interesting profile and cohesive texture.

Session rating – 8.8/10

Water rating for this tea – 8.5/10

Reviewing the Water Itself

Drink up!

55ºF. Odorless, it hits the mouth, very thick and full for water. Holds together well. Mildly sweet, can taste the air in the water. It really is smooth and dry in the same way that the tea made with it is. Aftertaste is pure enough, could be more pure. Extremely slight CO2, not as much as Saratoga. The sulfate expresses itself with a thickness and presence. Really smooth, not particularly crisp, heavy but empty. Satisfying water with a sort of plain, ordinary and natural character. Could be more thirst-quenching.

Water rating – 8.1/10

What did I learn?

First, Xi River is really heavy. Unless there’s something I don’t know about how to get scale to stay in water and not precipitate out, it’s just a water that scales aggressively. I feel like the time investment that it took to make this water was worth it in the same way that the money investment for Treachery is worth it. I learned that silica makes a positive difference. I also learned that I can make good base water now, albeit with great effort. I got to know Treachery more, the qi was extremely comfortable and beneficial. This is good tea water in my book. I thought it could be a bit more present, but there was a sort of authenticity to what I was replicating here, or at least my idea of it, having never tried it. It tasted ordinary yet elegant, and seemed to express the tea in a beautiful, rather emotional way. I want to improve my process and make more water – I have plenty to replicate and even more water to create and design. I really enjoyed this session and process – it is like reverse-engineering nature.

Between (Three) Teapots

I was recently featured on Crimson Lotus Tea’s livestream show, Between Two Teapots! I got to talk about water with Glen, founder of Crimson Lotus Tea and with Arby, my friend and water collaborator. We drank the same tea with the same water recipe that we created, Truth Serum. Two hours long, I feel like we only scratched the surface. Here it is for you to watch!

I found it amazing that Glen noticed an obvious difference in the tea brewed with Truth Serum compared to his normal water. This is due to the Hardness to Alkalinity ratio (see the WIP Water Guide) being twice as high as his usual. The sensory overload of extraction that you can get with TS is really quite fun to explore! I can’t wait to make more waters that are a bit more subtle and subdued, while still delivering plenty of power. Feel free to message me on IG @teasecretsblog with any water questions – I’m here to help you dial in your tea.

Replicating my own tap water

I finally got my water tested!

With the help of Ward Labs, now I know what minerals are in my tap water. For $48, they analyze any water you send them for the main important ions, plus iron and nitrate. I was really excited when I got the results, because they confirmed a lot of my hunches about its composition from simply tasting tea made with it and comparing with my various experiments. Without further ado, here is the composition of my local Massachusetts groundwater.

pH6.9
Stats

It’s immediately apparent that there’s a lot of sodium and chloride in this water. I had a feeling this would be the case, as our roads are heavily salted in the winter and that all goes into the ground. I also had a sense that with such a high TDS, but no scaling, a lot of the mineral content would be salt. This salt doesn’t make it taste salty at this concentration, but does increase the mineral taste of the water and adds a bit of viscosity.

The other strange thing about this water is the high Hardness to Alkalinity ratio of 5.36. This is caused by medium calcium and magnesium but very low bicarbonate. I’ve never seen a hardness to alkalinity ratio this high in a natural water – they are almost always between 0.5 and 1.4. But, this is proof that water comes in all different shapes and sizes. When I make tea with my tap water, I notice that it does lack some of the deep texture that it would have with more bicarbonate, doesn’t scale as it would with more bicarb, and has very present flavor and brightness, as those bright acidic tastes are not buffered by any bicarbonate alkalinity. It’s not particularly harsh water despite this high H:A, it’s actually really smooth and enjoyable. The silica in there is a nice bonus, too.

Cupping the replica tap vs the real thing

I decided to replicate the tap water with distilled water and various salts, down to the milligram. I even added some eidon silica concentrate. Then, I used a cupping set to see if there was a difference – I want to see how fake water stacks up to the real thing!

Tap on left, fake tap on right

I used a dancong from Yunnan Sourcing to do this comparison, with 3.1 grams in each 150ml mug, steeping for 5 minutes. The fake tap came out a bit darker than the real tap, but it was pretty close.

Real Tap

Smooth and oily with fragrance

Texture better, airy, thicker

Fake Tap

More rear focused

More astringent

More robust

Despite my criticisms of the remade tap, they were fairly similar, with the same general idea – high fragrance, high minerality, low alkalinity. The flavors were similar as well. I have a theory why they were so different – I used sea salt instead of pure salt. Sea salt is 30 percent magnesium chloride. Whoops! So, to anyone making a mineral recipe with salt, including Truth Serum, it makes a big difference if you use pure NaCl (which is hard to find without anti-caking agents, but there’s a link in the Water Guide). This experiment will be worth repeating in the future with pure NaCl.

What did I learn?

The general takeaway, besides the impurity of sea salt, is that fake water is an approximation, and there are many factors that make natural water superior to it. (Edit: this is to say, given the same mineral profile. An artificially made good mineral profile is better than a naturally bad one.) Now that I know the mineral content of my tap water, I can make small (or large) adjustments to it to modify how it behaves with tea. I really appreciate that my tap has good amounts of sulfate and chloride, as I can always fall back on it for a decent cup of tea.

Sorry for being so slow on the water guide, there’s a lot to type. It will get done though! Let me know if you get your tap tested, and what the results are!

Water Recipe #3 “Truth Serum” Updated Version

This is a review of the updated Truth Serum water recipe. I reviewed the old version here, but Arby at empiricaltea.com has changed the recipe quite a bit, and he prefers it over the original. Let’s see how it performs now! He recommends making a concentrate of the recipe, which is a great idea. To test it out though, I’m just making a single gallon batch. What’s apparent from looking at the recipe is that it’s very similar to the last recipe, 2/3 Heavy. The difference is that he added NaCl to be able to increase the sulfate and bicarbonate. This isn’t really how it happened, as he tweaked the first version of his recipe over many iterations, but it’s interesting that the recipe arrived in a similar place to 2/3 Heavy.

It’s also important to note that I used a special method to make this recipe. I frankly don’t know if it changes anything, I would have to make it the normal way and then cup it against this batch – hopefully I’ll get around to it! Basically, instead of adding the minerals directly to the water batch, I added them to a pyrex beaker of distilled water and stirred them with a glass rod. When they dissolved completely, I poured that into the main batch. This way, every mineral dissolved on its own, so there’s less of a chance of impurities reacting in solid form. The idea is that if minerals are dissolved in water that already contains ions, weird reactions could take place, so this method avoids that. Let me know if you’re a chemist and if that’s a real concern or not!

The Recipe:

(To purchase the materials you need, please visit the Water Guide.)

Short instructions: in one gallon of distilled or other 0 ppm TDS water, add each mineral one at a time. Carefully weigh each mineral on a milligram scale (not a regular gram scale) and make sure all of it has made it into the water and none is left stuck to the tray. Clean the tray between weighing each substance. Wait at least a minute between adding each mineral. When done, wait 20 minutes for the minerals to dissolve, shaking occasionally. If you have a different size container, use 1 gallon = 3.785 L to convert the amounts. For example, if you’re only making 1 liter, divide every amount by 3.785.

Session 1: 2018 White2Tea Smoove Cocoa Minis

Arby recommended I try a ripe, so here goes. For info on performance with fragrant teas, there should be enough results from Session 3 with the Green Hype cake.

4g/50ml gaiwan, 100ºC

Early impressions: Wow! Thick and expansive. Bitter. Woody. Second steep was around 20 seconds. Black as ink. Holy cow. There’s something really really nice about this. The coffee-cola is very pronounced, but there’s also activity in the front. A short steep to see what’s really going on… still has a great complexity and full color. Getting qi as well. There’s a sharpness that’s evident in a lot of higher Hardness to Alkalinity waters here, but you’re rewarded with body, viscosity, and really striking depth of flavor. Wood, acidic earth, and of course, nice cocoa.

so dark

Mid-session: Consistent dark color and root beer chocolate in the back of the mouth. Deep aftertaste, but unlike the previous version of the recipe, plenty of vibrance and sweetness. I think it’s the chloride! Anyway, even with very short steeps, still delivers enough strength and color.

Late Steeps: As expected, gradually diminishing sweet molasses, mushroom, earth and vanilla cream. Mouthfeel remains pleasant, no drying.

Session Rating: 7.9

Water Rating for this tea: 9.0

Session 2: 2001 Zhongcha Huangyin from Teas We Like

3.4g/50ml gaiwan, 100ºC

Lots of saponins in the rinse

Early impressions: Aroma coming from the wet leaf is intense. Barbecue sauce. First steep is sweet, sour, smoke. Stable bubbles in the center of cup on second steep. Aged sprite aroma on wet leaf up close. Taste is vibrant, dynamic, evolving, hard to pin down. Juicy! Lime juice in front, but not as sour. The citrus is dominating, which is extremely unusual for this tea. Let’s see what happens.

Mid-session: Density coming in now, some astringency, but appropriate. I seriously don’t know what I’m tasting right now. Wood bitterness, not hitting the sides of the tongue very much. The session so far reminds me of natural waters, mouthfeel especially. Ok, hitting the sides of the tongue with sour wood, light earth taste in back, great great throatfeeling, refreshing. Honey aftertaste. I’m finding this tremendously different and enjoyable. Heat in upper back, general relaxation. It’s really tasting younger this session than usual. I’m really taking my time with this one. Tobacco leafiness, light mulchiness. Tons of resin and even bubblegum, or gum base. A little bread dough too, sourdough. Sweet and bitter, sour and savory. (not salty).

not very dark

Late steeps: Beginning to dry the tongue. Good texture. Really a lot happening up front, lingering bitterness in the back. Definitely arrives in the front this time, where last week it arrived in the back. I can’t think of any explanation – I would usually associate sulfate with more rear mouth flavor, but something’s going on here I can’t explain. I guess the sulfate and chloride are in balance for this water profile. Citrus sandalwood aftertaste. I think there’s plenty going on in the back, but it’s simultaneous with the front. There might be some variation in this cake that could account for this difference in taste and lighter color. But it could also be the water! This was a very avant-garde session. Highest qi so far.

Session Rating: 7.5/10

Water Rating for this tea: 7.5/10

Eating lunch! Then an hour break.

Session 3: 2019 White2Tea Green Hype

3.3g/50ml gaiwan, 100ºC

Early impressions: Delicious. Full of candy sweetness, smoke, savoriness, brininess, sweet huigan, honey, citrus, black tea bud sweetness, body. Wet leaf smell deep and pleasant. Rather salty this time. Salted lemons, is this springbank 10? It’s got notes that I would usually get in much more expensive teas. Texture is great. Taste is nice and present, front-focused again.

😀

Mid-session: savory, back of mouth presence suddenly. Rather expansive texture. Definitely evokes the idea of a “serum.” Smoked fruit. Olive oil. Minerals. Floral mouthcoat. Definitely delivering on the top notes. Sweetness and depth both are here. I feel like with the original Truth Serum, there was depth, but not enough sweetness, so this is a welcome change. Strong lime and even avocado oil here. Astringency is medium-high, rather appropriate for this young, strong raw puer.

Late steeps: Gasoline. Still sweet, still textured. Leafy, astringent honey. Some pineapple taste. Grapefruit rind. Huigan isn’t tremendously strong, but it’s there. Energy is very high, caffeine. Buttery. Lemon jelly pastries. Sweetness and gasoline taste continues through the last drop.

Session Rating: 7.5

Water Rating for this tea: 8.0

Overall impressions:

A definite improvement over the previous version of the recipe, definitely more of an all-round water. It really has a great balance and works well with at least the three types of tea I tried. It’s also not overly heavy. This water will be hard to beat – I’ll be using it as a benchmark from now on. Perhaps it can be improved with potassium for more back of mouth complexity, but who knows? If your tap water is no good for tea or you are at all curious about water, please give this recipe a try!

Water Recipe #2 “2/3 Heavy”

This recipe was formulated in November 2020. I made a heavier version of this recipe first, which I called “heavy” and then cut it down to 2/3 concentration, hence the name, 2/3 Heavy. I could have done a more creative name, but it’s what we’ve been calling it on the tea discord where a few other people have been making it and enjoying it, as well as the previous recipe, Truth Serum, which was developed after. Big thanks to Arby and everyone in #water on the CommuniTEA discord for helping out with evaluating this recipe! This water is more chloride focused than sulfate, and includes potassium. It was designed to have a little bit of everything: fragrance, presence and depth.

The Recipe:

(To purchase the materials you need, please visit the Water Guide.)

Short instructions: in one gallon of distilled or other 0 ppm TDS water, add each mineral one at a time. Carefully weigh each mineral on a milligram scale (not a regular gram scale) and make sure all of it has made it into the water and none is left stuck to the tray. Clean the tray between weighing each substance. Wait at least a minute between adding each mineral. When done, wait 20 minutes for the minerals to dissolve, shaking occasionally. If you have a different size container, use 1 gallon = 3.785 L to convert the amounts. For example, if you’re only making 1 liter, divide every amount by 3.785.

Session 1: 2019 White2Tea Fireflake Dancong

3.3g/50ml gaiwan, 100ºC

This is a strong, punchy, intensely fragrant oolong with a high roast.

Early impressions: brews up dark, more orange than your typical dancong. First steep is sweet, floral, and buttery. Bitterness throughout the mouth, but not unusual for this tea. Taste in the front of the mouth is immediate, and on the swallow there is a present bitter roast aftertaste. Second steep is intensely dark. Dense taste of sweet chocolate and coffee with butter and tannins. Obviously too strong, but has redeeming qualities. I guess my ten second steep was overkill! Switching to flash brews. Viscosity is medium. Activity in front and back of mouth is equal.

Very dark for dancong

Mid-session: Tea is still strong. Quite sharp arrival, sides of tongue has roasty sourness, but it all blooms into a thick fragrance that evaporates in the mouth. General flavor is sour roast with floral butter in the aftertaste. Astringency is medium-high. Thank goodness for the sweetness here to balance that all out. I have had worse sessions in the past with this tea. It’s full of character, but it’s a beast. More of a rushed flash steep brings a more balanced profile, intense fragrance and roast but with viscosity and refreshing fruit notes.

Late Steeps: I definitely feel like I’m getting a complete picture of this tea. The taste and aftertaste are fully present. This tea is not letting up on the strength front, drying up my cheeks. Aroma on the gaiwan lid is extremely enjoyable as well as the wet leaf, pungent floral, and cooked celery. (?!) Around steep 8 this tea is settling into a much more pleasant stage, with a nice warm profile of nutty floral aroma with a buttery taste in the front of the mouth, like brown butter. Caffeine is strong, amazing get-it-done energy. Warming to the core also, while most dancong usually cools you down. Loving the sugary greenness as the roast fades later in the session. This is a tea to flash flash flash until it lets up, then enjoy rewarding late steeps.

Session Rating: 6.5/10 – Overwhelmingly strong and punchy, but with plenty of redeeming qualities to be a success.

Need a break already! Then we will press on to two teas I tried last time.

Session 2: 2001 Zhongcha Huangyin from Teas We Like

3.4g/50ml gaiwan, 100ºC

Early impressions: Wash smells very clean, earthy sprite aroma. Two rinses as this is one chunk. Elaborate wet leaf aroma, full of citrus and darker fruits, earth and wood. Liquor on the first steep has the yeasty smell that you usually get with aged sheng when you use much harder/heavier water, like toronto water for example. This is encouraging, as I like that note but I don’t like tons of scale in the kettle. This recipe doesn’t scale at all. Nice present early taste, generally sweet wood. Still opening up. Glorious raisin-craisin smell in the gaiwan. Water does affect the wet leaf smell more than you might expect! Now at a peach color, the tea produces great viscosity, medium thick. Flavor first hits in the back, surprising! In the front of the mouth there is sweetness, sparkling feeling, but a lot of the activity is happening in the back of the mouth with gentle wood bitterness. I am blown away by the texture though, extremely pleasant.

Middle: Vivid. Clear dirt-earth-dust in the back, fruit expressing itself in the front. This tea seems to move back-to-front, which is quite unusual. It first hits the sides of the tongue, then the back, then the front. Flavors are sweet, some floral qualities, but the sensation is deep gentle bitterness. Low astringency. There’s a cinnamon stick quality to the sweetness, and the bitterness is primarily wood. The front of the mouth has some powerful astringency now, but not excessive. Brown sugar, pine resin, root beer (birch beer tree). The clarity of experience here is striking, nothing seems to be hidden at all. It is rather sharp and quite immediate, but the experience of drinking lasts a good, dynamic 30 seconds. Energy coming through now, heating in arms and clarity.

Late: Maintains complexity while evolving. Leaf decay, bittersweet, honey, grains. Still present, hits in the front more immediately now with the lightest of brown sugar and hardwood. Two minute late steep – clear front presence, sweet grapey winey quality, like wine aged in a whisky barrel… in the forest. Extremely aggreable.

Session Rating: 8.0/10 – in a completely different way from Truth Serum 1.0, this session hit the mark: for thickness, complexity, and presence. Somehow bright and deep all at once.

Session 3: 2019 White2Tea Green Hype

3.3g/50ml gaiwan, 100ºC

Early impressions: Wet leaf immediately a smoky, floral, sweet, buttery affair. First taste – sweet ripe stonefruit. Smoky, but more like smoked fruit than fruity smoke. Great sweetness. Definitely front focused at the outset. Immediate taste. Complex sheng gasoline. Oily and energetic. More please!

Beautiful leaf

Mid-session: So bright and upfront, sparkling on the tongue. Artichoke, snap peas, fresh apricot, red bell pepper, and a rice crispies sort of sweetness. Astringency is medium here, oiliness is also medium. In the throat, there’s a huigan, and mostly pine bitterness, like hops. There’s a toasted rice graininess that brings it into the scotch whisky realm, as if it were a young single malt. Energy is generally uplifting, with heat in back. Longer steep has more bitterness, which is quite satisfying if a little straightforward.

Good tea here

Late steeps: Wet leaf has the most pure leafy-smokiness. Taste beginning to settle into a sort of smoked lemon-lime soda, with a backbone of bulang gasoline strength. Very cool fermenty sourness coming in, like a sour beer. Rather glorious dynamism for a sheng in this price bracket. Green leafy aftertaste throughout the mouth with a tannin-coat. Pectin. One minute late steep, still fresh, but with obvious peppery notes coming in.

Session Rating: 7.4/10 – I’m rather blown away and I don’t think you can do much better than this with this particular tea. Incredible experience of changing flavors.

Overall impressions:

This medium-strength recipe provides a well-rounded experience, with high clarity, fragrance, and sweetness with appropriate rear-mouth activity and viscosity. 2/3 Heavy strikes me as a good benchmark for custom standardized water, as I felt I was getting front and back of mouth activity for all three teas. It doesn’t strike me as particularly dishonest, but it may make flawed teas taste passable rather than highlighting their flaws. I don’t always get such good results with this recipe, but I was very patient in measuring and dissolving each mineral this time, and my patience was rewarded. Additionally, I got less conductivity error than last time, which is quite encouraging. Overall I’m very pleased and am testing many variations of this recipe side by side to better understand water.

Water Recipe #1! “Truth Serum 1.0”

Today marks the beginning of a new series of weekly water review posts! Arby from http://empiricaltea.com/ and I have been working on some water recipes for tea. His epsom salt and baking soda water recipe was one of the first I tried years ago, so it has been really cool to connect with him. This week’s recipe has been a long time in the making, and was a collaboration between me and Arby, although I consider this to be his recipe as he made most of the decisions and did almost all the testing, while I offered advice. He designed this water to accurately reflect both the positive and negative qualities of all types of tea, hence the name “Truth Serum.” I’m really excited to share it with the world, and also to try it with a few teas and give my impressions of it. He also has an updated version of this water recipe on his blog, so definitely check that out! License: No commercial use of this recipe is permitted without permission from the creators.

The batch

Tasting Procedure:

All teas were tasted on the same day, with the same batch of water. The kettle was refreshed for every new session. Table water crackers were eaten between sessions and sometimes between steeps to clear the palate. Water was boiled in a glass kettle using gas for the initial boil and an infrared hot plate during the session.

Session 1: 2020 White2Tea Turtle Dove

3.3g/50ml gaiwan, 100ºC

First of all, it seems like the water is measuring slightly under on the conductivity meter, and I’m not sure why yet. There’s about a 6% error, which I don’t think is too bad. I’ll test again tomorrow after the water has settled a bit.

Early impressions: This is normally a fragrance forward tea, and I’m getting fragrance, but also a lot more. Aroma from the wet leaf is nice and potent, floral. In the mouth, it’s very coating, with creaminess and sweetness. Very floral aftertaste. Depth, likely from the sulfate. Root vegetables. I have to say, there could be more high-note fireworks in the front of the mouth, but they come in the aftertaste after swallowing. The more vegetal notes are apparent while the tea is in the mouth. Thick texture.

Yummy

Middle of session: Soothing. Good herbal and peppery taste. Hay and cream base is present. Consistent bubbles on the surface of the tea. Sticky texture, no astringency. Honey-sweetness. Great ECA (empty cup aroma). I have to say, I would like a bit more brightness here. Feeling some qi, more than with lighter water for sure. Lots of activity in the back of the mouth/throat now. Sweet yunnan black tea huigan. Actually tons of changing tastes in the throat. Vanilla? Some sort of vegetable taste like fresh peas in the pod. Snap peas!

Bubbles

Late steeps: satisfying potency, doesn’t seem to be running out after 9 steeps. This water definitely extracts thoroughly without feeling like your mouth is being extracted, which is nice, naturally! Pushing the steeps longer now, around a minute. Very relaxing. Good presence in the center of the tongue, giving a solid base taste. Not overly sweet, but some sweetness is present. Aftertaste is very nice. Nothing harsh, but a little bitterness to tell you when you’ve steeped too long. Good evolving bitterness when pushed.

Session Rating: 5.7/10 – pretty good, but leaves some front-of-mouth vibrancy to be desired.

Eating crackers…. now onto session 2!

Session 2: 2001 Zhongcha Huangyin from Teas We Like

3.3g/50ml gaiwan, 100ºC

Wet leaf smell is dense and intense, and minty. I’ve had this tea many times, so I’m quite familiar with it.

Early impressions: thick. Detailed and full savory leathery notes, even on the first steep. Pungent sweet incense on the sides of the tongue, wow! Bubbles on surface of liquor on second steep. Wet leaf has a creamy smell to it on top of the other complex incense, earth and wood smells. Takes a while in the mouth to arrive, but worth the wait. Concentrated oily texture delivering mouth-coating complexity. Bitterness with raisin taste in the back. Sweetness just barely present. Some mouth cooling. I love the length of the experience, it really takes 15 seconds for the flavors/sensations to be delivered in sequence.

Amazing

Mid-session: Bitter wood, really natural taste. Astringency appropriate for natural taiwan storage. Deep orange peel, varnish, strength and potency even in a 50ml gaiwan. Solid energy too. Warming in back and grounding. Pushed steep brings some flavors to the front, some tannins, wood aromatics. Very crisp, brisk, if you know what I mean. Alerting taste, astringency. Leaves have opened nicely with a wonderful wet leaf aroma of buttery fruit and wood furniture. Something about the taste/texture suggests wax, in a good way.

Aged raw puer tea

Late steeps: Hints of dried apricot coming in, still a lot of power. The liquid seems a bit heavy, tends to pool rather than splash, but it swallows naturally. Really impressed by the texture, delivery, extraction and rear-throat sensation. Some cool citrus bitterness is happening, extremely present/vivid flavor and sensation. Pleasant acidity. Aftertaste is complex. Lots of warming, nice! Could be slightly thicker. All sorts of incense powders in the taste. Definitely bitter, no doubt about it, but detailed and evolving bitterness, with a subdued, very dry (not drying) sweetness. Also, great longevity, did not get tired after 12 steeps, could probably go quite a few more.

Session Rating: 8.0/10

Having some light food, crackers, water and a break.

Session 3: 2019 White2Tea Green Hype

Ok! Another tea I know well.

Early impressions: wet leaf full sugary intense young sheng smell. First taste is great, coating. Fruit flavors, lime, bit of smoke. Sweetness, but again not overly sweet. On the less-sweet side. Definitely slightly heavy and dense. Again, lengthy arrival, flavors sensations and delivered in sequence over about 15 seconds. Thick! Nice ECA. Savory vegetables and herbs with gasoline potency.

Water Hype!

Mid-session: wet leaf aroma is amazing. Bubbles on surface of tea again. Amazing how there is consistency in totally different sessions from the water’s characteristics. More energy than usual for sure. Briny, I think from the tea, not the water. Good presence in front of mouth with sweet lemon, ashes in the back. Splashing a bit on the top of the mouth which is nice. Rather astringent, which is not unusual for this tea. Potent! Medium mouth-cooling. Salted-watermelon taste (a southern tradition!)

Late steeps: In astringent territory now, but still delivering the base citrus and gasoline-strength. Qi. The fresh citrus is nice, very IPA-like. Cooling cucumber notes hiding underneath the bitterness. Enjoying the texture, grippy and cohesive. Some woodiness/stemminess coming in. Some lemon lip balm notes on the gaiwan lid.

Session Rating: 6.8/10

Overall impressions:

This is a medium-heavy water recipe, with high sulfate and low chloride. As a result it seems to be more rear-of-mouth focused, and less sweetness/fragrance as the tea is in the mouth. Fragrance comes, but mostly in the aftertaste and can be experienced in smelling the wet leaf and empty cup. Strengths include bringing out complex bitterness, full extraction, aftertaste and thickness. Weaknesses include lack of front-of-mouth taste detail, a bit heavy, and lack of immediacy of taste. However, with patience, this water delivers a great, satisfying experience. This water is likely best with aged sheng and darker teas, rather than fragrance-forward lighter teas. Yancha would likely work well also, especially higher roasted wuyi oolongs. Overall, since I do get fragrance in the session, I think it succeeds in capturing the different aspects of tea in a nicely balanced, characterful way.

Average session rating: 6.8/10

Water rating: 7.3/10

A couple drops of silica concentrate improved texture and cohesion in earlier tests, but for evaluation purposes it was not used here. The conductivity error is definitely something to look into. I also have a version with potassium which I have not tested yet. As is, I recommend you give this water a try, as it will possibly show you a different side of your tea than you are used to. Big thanks to Arby for making this recipe and I’m very curious to see his review! Feel free to tag us on Instagram, @teasecretsblog and @arbyavanesian and let me know your results there or in the comments here.

Next week, new water, new teas! Look forward to it!

2004 Biyun Hao Manzhuan with Fake Toronto Water

After a couple hours of work, I was able to make a slightly shuffled-around version of the Toronto water recipe from my last post, Replicating Toronto Tap Water. The mineral content is the same. So, I figured it would be fun to make tea with it and take some good old fashioned tasting notes, a-la-mgualt. I’m not too experienced with this kind of steep-by-steep report, but it seems like a useful way to document the experience.

6.5g/100ml zini, glass kettle, 232 TDS (calculated) water, pH 8

Homemade water in the kettle

1.

Nose: Wonderful yeasty-woody smell coming off the liquor, something I don’t get from my normal water or other lighter recipes. Wet leaf extremely surprisingly pungent, sharp wood incense, damp wood shavings, cooked mushrooms, chocolate.

Mouth: Sweet deep fruity taste, like plums and wood. Bready aftertaste, like sourdough. Relieved that I’m not getting plastic taste, as source water is distilled water from the supermarket. Still would like to find a better source.

Body: Calming, warmth in upper back, settling in.

2.

Nose: Pronounced earthy depth on liquor. Wet leaf has pungent chocolate-coffee aroma. Cherries on wet leaf.

Mouth: Nice bubbles on liquor. Oily texture, mouthcoat, mouth cooling. Some precipitation of calcium carbonate on the surface of the tea. Rich, sweet dark chocolate cake taste. Definitely sweet mushrooms as well in the front. Not much bitterness yet. Huigan starting to set in, sweetness mixing with sourdough bread aftertaste.

Body: Warmth, some sweating. Calm and focused. Awake.

3.

Visible scale in the kettle, this is hard water after all!

Nose: Can almost smell ripe tropical fruits on wet leaf. Some florals and balms on empty pitcher.

Mouth: Mushroom soup, almost fatty. Bitterness coming through now, but balanced.

Body: Relaxed and open. Warmth spreading to ribs now. Warm fingertips. Smiling.

4.

Nose: Wet leaf still smelling like warm tart cherries and decaying wood. Liquor has a waxy melted candle-like smell.

Mouth: Texture is quite sticky, settles in nicely after a few seconds. Not overly thick, could be more expansive. Sweet-and-sour taste. Slight mouth drying, could be from the scale.

Body: Alert and grounded.

5.

Thickness

Nose: Wet leaf has deep wood and tobacco.

Mouth: Grappa-like raisin and grape notes, hints of some sort of flower or herb essence. Vivid earth taste. Still great oils. Great complexity in back of mouth, younger-sheng-like fruitiness (citrus huigan)- front is more on fruit sweetness and earthiness.

Body: Dizzy, vivid colors, zoned in. Heat mostly in lower and mid back now, not really present in neck and ears. Interesting.

6.

Really scaling as the water continues to boil.

Nose: Hot chocolate with marshmallows on liquor, wet leaf mostly natural woods.

Mouth: Bourbon-like wood sweetness. Taste getting more subtle now. A hint of yellow squash, but bitter wood incense is quite noticeable. Texture quite thick, definitely some tannins coming through. Vivid jasmine tea aftertaste!

Body: Some swirling energy in fingers and core. Enjoying breathing.

7.

Long steep here, about a minute.

Nose: Some black (red) tea smell. Sweet grasses. Meringue on wet leaf.

Mouth: Amazing bittersweet bready oily taste/sensation. Sunkist Lemon gummies. Fruit pectin. Feels like this water is extracting the tea to the core. Jelly beans (not jelly belly, the cheap kind) and bark mulch. Less structure than I would expect, perhaps the scaling has made the water go a bit flatter. Although I don’t like using the word, there is dirt in the aftertaste.

Body: Floating feeling. Aware of breath, deep and slow. Warmth in forearms.

8.

Nose: Wet leaf has key lime pie. Some granite-like smell. Decaying wood, but not musty. Just warm like old books.

Mouth: Some sort of spice, like a cinnamon stick. Definitely tasting lighter now. More general woodiness and tannins, less fruit.

Body: Very relaxed, could take a nice nap.

9.

Don’t mind the spill…

Poured out the remaining water from the kettle and refilled. Let’s see if this changes the tea…

Nose: Fading a bit.

Mouth: Definitely more lively and expansive in the mouth. Refreshing sweet yeastiness. Texture is great. A little bit of green beans.

Body: Totally chilled out. Very comfortable.

Late.

Loooooooong steep, 3 mins.

Nose: Smelling more spent, faded woodiness.

Mouth: Tannins and wood, with a pleasant sweetness. Nice sugariness.

Body: General warmth.

Experience Rating: 8.2/10

Thanks for reading!

A seriously deep and rich taste with this water. I had this tea with my normal tap water and although it was good, it didn’t have these yeasty rich bready chocolate notes. I would have to say this was a better session than with tap. The scale is annoying, so maybe a slightly lighter version of this water would be even better.

Replicating Toronto Tap Water

The following is an account of an experiment I did in April 2020.

The Context

I had been messing with water for two years, adding minerals to pure water and trying all sorts of different brands, with varying results. I was having fun, but I knew there was better water out there than what I was making, buying, and getting out of my tap. As I was reading Late Steeps, Marco Gualtieri’s tea notes blog, I noticed he seemed to be getting amazing sessions with aged teas like the 2004-06 Yang Qing Hao productions. I’m aware that now his opinions of those teas have changed a bit, but back then he was enjoying them, getting tons of intense flavor and engaging energy. My experiences with Yang Qing Hao were less stellar, more boring and flat. I started to wonder… what if it was the water? Marco lives in Toronto and was using tap water usually in his older reviews. I looked up the water quality report and thought,

What if I could make Marco’s tap water in my own apartment?

The Process

The first thing I had to do was figure out the mineral composition that I was going for. The water quality report has minimum, maximum and average ranges for each of the relevant mineral ions; for example, the calcium content is between 31.1 and 38 mg/L, with an average of 35.6. I decided to aim for the averages, and see if it led to any problems. I used a slightly modified version of the Khymos mineral water calculator to convert my target ion concentrations into a mineral recipe that I could use.

(Ignore the carbon dioxide and pH, they are wrong, and also it’s not grams on the right column, but milligrams)

The ion charges didn’t match up, so I let the calculator compensate by adding bicarbonate to balance it out. 118 mg/L of bicarbonate was still within the range on the water quality report. This water is very heavy, and pretty hard. However, the hardness is higher than the alkalinity, which basically means that the flavor won’t get eaten up by excess bicarbonate. In general, the hardness to alkalinity ratio should be above 1 to prevent dullness of flavor. However, Icelandic glacial is decent for tea and has a hardness to alkalinity ratio of 0.85. This toronto water replica has a ratio of 1.32.

The amount of each mineral I had to add per gallon was all the way on the right column, in milligrams. I needed seven ingredients in my water to get that Toronto profile. My plan was to add them one at a time until I was done, pretty simple. If you add them all at once, there’s a chance they might react in some negative way.

The gang’s all here

The first five minerals, NaCl, KHCO3, MgCl2-6H2O, MgSO4-7H2O, and CaSO4-2H2O, dissolve fairly easily in water. However, the last two ingredients, MgCO3 and CaCO3 (chalk), are insoluble. So what did I do? Khymos instructs to carbonate the water – put simply, this produces carbonic acid which reacts with CaCO3 and MgCO3 to form soluble/aqueous Ca(HCO3)2 and Mg(HCO3)2. This works, but you end up with bubbly water, which I didn’t want to use for tea – I wanted to simulate what someone in Toronto would get out of their tap.

Bubbling and Debubbling

Debubbling

Luckily, the local Publix supermarket had Syfo Seltzer, a Reverse Osmosis carbonated water with 0 mineral content. My strategy was to make two concentrated solutions: I dissolved a gram of chalk in one bottle and 500 mg of MgCO3 in the other bottle, left it in the fridge over two nights, and rotated the bottles every once in a while until they were clear. Then, when it was time to make the water, I used a winemaking air pump to bubble air through each of the concentrates until the solution reached a pH of 8 or above, meaning all the dissolved CO2 was basically gone. I tried using a vacuum chamber for this another time, but it didn’t seem to work as well.

pH 8!

Making the Water – Putting it all together

A pinch of salt

It was then an iterative process of measuring out minerals, dissolving them in 0 TDS RO water, and then pouring that into the big jar.

Et cetera

After the first five minerals were added, it was time for the CaCO3 and MgCO3 concentrates. I simply measured out the appropriate amounts of each – one ml of the CaCO3 concentrate contained one mg of CaCO3 (in a way) and one ml of the MgCO3 concentrate contained 0.5 mg MgCO3.

This is only some of the chalk concentrate – there’s a lot in this water!
Pouring it in, almost done!
Finished
There are ions in this water is what this reading means

The TDS (Total Dissolved Solids) measured 148, even though the calculated TDS was 232. Quick note about TDS meters – they measure conductivity and multiply that reading by a constant to estimate the TDS. This water is less conductive per mg of TDS than the solution that the meter’s coefficient constant is based on. Bicarbonates are much less conductive than chlorides and sulfates. My meter’s coefficient is actually smaller than the commonly accepted one, too. So, that TDS reading was nearly meaningless, and the water was likely actually the proper TDS.

Taste of Toronto

I’ve never been to Toronto, but the finished water had a nice, natural mineral taste. It really didn’t taste synthetic, and was quite full and soft. I was impressed! The whole process took about three days, with two hours of work total.

Making the Tea

Ok! Now that the water was finally done, it was time to test it out. I had some Yang Qing Hao Jinhao Chawang lying around, so I fired up the kettle and did a little session.

The result was astounding. I had never experienced such a concentrated, thick, powerful tea before, especially from Yang Qing Hao. It’s hard to describe, but it was so satisfying, and I felt the energy much more than other sessions. I could tell that the full potential of this tea was being extracted, but the bicarbonate was providing a wonderful softness and richness. I now understood where Marco was coming from with his praise, when before, with Nashville water and even bottled water, I never got close to this experience.

Many other sessions were had with this gallon of fake homemade Toronto water.

I forget what tea this was

It was all amazing. To be clear, this water is heavy. You couldn’t go much heavier than this and have a good experience. But the calcium and magnesium are in perfect balance, as well as the sulfate and chloride, hardness and alkalinity, just a bit of potassium, not too much sodium. This, as I understand it, is a great mineral profile, especially for a water as heavy as this. I also like lighter waters, but there’s something with this Toronto water, this density in the resulting tea, that is extremely addictive. It’s too bad it was so hard to make. I plan on making it again, with a slightly easier method that shuffles the minerals around so I only have to make one concentrate.

So yeah, this is one example of what I’ve been up to in regards to water and tea. If there ever was a tea secret, this is one – water mineral content has an enormous effect on tea. I’m not suggesting everyone should make this water, as it’s rather difficult and time consuming, and maybe not for everyone. I feel like most people know that water has an effect on tea, but don’t know what to do about it. There’s probably a 50-70% chance that your tap water, when filtered to remove chlorine taste, is good enough. But if it isn’t, it might be worthwhile to find a solution (haha) to that problem, to get the most out of that hard-earned tea. Also, it’s just fun to play around with water! This experiment really opened my mind to what’s possible with a little chemistry and imagination, and I’m looking forward to making water that’s even better than Toronto’s.
