1) Bubbles on the surface of your tea are a good sign
Sometimes, when pouring tea from a pitcher into a cup, I notice a group of bubbles collecting on the surface. Sometimes, they pop or slowly move to the side of the cup, but occasionally they stay in the middle. Mgualt calls this the “jello effect” and it has to do with the saponins in the tea coupling with the right mineral balance in the water. Usually a cup of tea with jello effect will be thick and have good vitality. I have also had this happen with just water rinsing out the empty cup and pitcher, but this could be residual saponins on the teaware.
2) Excess bicarbonate in water leads to softer texture, but less flavor
I’ve taken a small hiatus from adding salts and other substances to my water (besides charcoal), but when I was adding baking soda (sodium bicarbonate) I noticed this trend. High bicarbonates = softer tasting water. FIJI water is known to be soft and it contains 153 mg/L bicarbonate, which is very high. Seeing that target total mineral content in my opinion is 40-100 mg/L, just the bicarbonate level in FIJI exceeds that. This is why I don’t use FIJI for tea, you can’t really taste the tea. Why this is, someone please let me know the chemistry.
3) The difference between 60% and 65% puer storage humidity is very significant
At 60, my puer becomes pretty sour and flat; at 65%, it’s sweet and active. That’s about it, it’s an obvious difference from smelling the cakes. I still happily drink puer stored at 55%, but if I had more humid storage space freed up I would place the tea in that.
4) A standard 6 gram tea session is a lot of caffeine and takes a lot of time
After my week without tea, suddenly I couldn’t get through a full session without my heart racing. For me, a session is 6 or 7 grams/100 ml, but I know others easily get through 10 grams/150ml in a sitting. This isn’t crazy, but it is enough to push your tolerance so that you may need tea to function, which isn’t what I prefer. A 100 ml session is significant, and maybe a half-size session daily will keep the caffeine addiction to a minimum, and make the larger sessions that much more special. Also, a gongfu session takes me around an hour and a half, mostly spent letting the tea cool and heating water. This is a significant amount of time and isn’t advisable to do daily unless you wake up reasonably early.
5) Slightly alkaline water is better than slightly acidic water
This is just a general trend, around 7.8 pH is nice and strong, while 6 pH like Voss is tart and thin. I don’t understand water pH, but that’s just something I noticed.
Thanks for reading and feel free to discuss with your tea friends.
