Master Zhou works with his students in the Qianjiazhai Dongsa Cooperative to start introducing shu pu’er fermentation and crafting techniques more widely across the mountain. This stunningly clean, rich and foresty example is crafted from pre-Qingming harvest maocha picked from one hundred to five hundred year trees. Master Zhou set aside a cache of this precious pu'er over a decade ago and agreed to release a small amount to show off the incredible complexity and depth that over ten years of aging brings to pu'er made from leaf and bud material picked in the oldest tea forest in the world.
