So here it is, my beloved green P'uerh cold steep after about 7 hours. It was plenty strong after about the first hour, so I had to keep adding water. Not sure what I was thinking, but up until this point I was only placing about a teaspoonful of tea into a quart sized mason jar. So I was thinking I had put a lot of leaves, but that it wouldn't quite be so strong. I think I put a tablespoon of broken leaves, the fannings from prying the leaves from the cake. Instead of creating more fannings, I thought I would indulge.
I noticed a slightly perfumey, herbal green taste from the tea. I could taste the aged edge that makes it so distinctive. I am rather impressed that a certain freshness could be tasted when cold brewed. However it still gave a mild bitterness or a bite that occurs in the hot steep.
I'm going to try a cold brew with my newer cake to see how the flavors will unfold.
