While it is only a first impression, I’d say this tea is not very good. It started out with a taste of wet wood. It then got sour for several infusions, It got a little better in later infusions. There were some sweet notes but not many. There was a lot of fermentation flavor in the early steeps.
I brewed this eight times in a 170ml teapot with 9.1g leaf and boiling water. I steeped it for 5 sec, 5 sec, 7 sec, 10 sec, 15 sec, 20 sec, 25 sec, and 30 sec.
