It is hard to date aged loose-leaf puerh, and impossible to do so perfectly. Most are blended over time, as shops add to them. Camphor Moon is an original 7542 loose-leaf puerh. We were lucky to get this one from a trusted source who has owned it himself for around twenty years. It could be from the 1980s but is much more likely to come from the 1990s. It is smooth and delicious with powerful warming energy. This is a chance to try a factory blend that is well aged. Of course, it has a wonderful, warming camphor flavor and aroma.
