This is a very good pu’er. The Yunnan Sourcing site states something about an “off” taste, but that must have been at the time it came into his possession.
Anyway, we consider this our house brew, at least I do. It has a very strong, black tea like quality, hints of astringency, sweetness, and “wildness.” The cha-qi is very high and though this can be brewed for a long time, it is probably most enjoyable Chinese style, something like 30s/1m/1m/1m/2m.
I’ve had this tea for over a year and a half. It hasn’t changed as much as some of the others. It has a consistent quality from cup to cup.
