I recently completed a gallon of water from one of my water recipes, and the result is interesting! I designed it based on the mineral content that I could find of various bottled waters related to wuyi yancha, like Wuyi Nongfu. This recipe is loosely based on loose data, but follows some conventions. These conventions are a dominance of bicarbonate, low sodium, <80TDS, and medium to high silica content. This is also similar to what you might find in Seattle, but just a bit heavier.
This batch was double distilled in glass from bottled Poland spring water, with a bit of fractionation involved. Silica content is 8 ppm. The water was well aerated before bottling overnight and brewing the next morning. I made some Old Ways Tea Da Hong Pao in a glazed Jiri Lang pot.
Initial onset is sweet and gentle, with a lot of the action happening in the rear throat, mineral tastes. Texture arrives a bit thin but some structure builds on subsequent steeps. Aftertaste is very long on the breath. The water does not feel heavy, there is a refreshing quality. A lot of nice sweetness and very integrated roast with some fruit and toasty rocky flavors. Some astringency but not very much. With this water, the tea doesn’t burst with flavors, it calmly settles into them.
Overall, it’s a bit too veiled for me, but worth trying. I’d love to try some real Wuyi Nongfu someday to compare. I wonder how to improve this water – for now I’m not sure, and as usual will keep making different waters and exploring. There seems to be a few things in my water making process that need improvement regardless of recipe, so I’m looking forward to working on those too.
