Bought this again recently. There was no discernible fermentation flavor to this tea. There was a slight wet storage note that lasted about three steeps. What was left afterward was a nice sweet note. I am not sure how to best describe it. The main question you ask about any tea that claims to be this old is are they telling the truth. Two reasons lead me to think this is vintage 1995 tea, one the owners of Tea Trekker are in my opinion honest. The second thing is there was no fermentation flavor at all with this tea. Usually in my experience only shou tea of approximately this vintage will have cleared completely. It also smelled old although that is hardly scientific.
I brewed this eight times in a 195ml Silver Teapot with 13g leaf and boiling water. I gave it a 10 second rinse. I steeped it for 5 sec, 5 sec, 7 sec, 10 sec, 15 sec, 20 sec, 25 sec, and 30 sec. There was no sign that the leaves were finished mind you but eight steepings from a 195ml teapot is quite a lot of tea. I think I would have gotten another six steepings out of the leaves. Going to store some of this in a Yixing container and see if the wet storage note disappears completely.
