This tea is picked from the early spring leaves and tender buds of the Camellia Crassicolumna tree, a close relative of the tea plant native to Qianjiazhai. Crassicolumna is naturally caffeine-free and high in antioxidants. The Dongsa Cooperative slowly sun-dries the tiny harvest of Crassicolumna sheng and finishes it like their tradtional sheng pu'er. Wild Crassicolumna is a rare and threatened species. This tea is sustainably harvested from cultivated trees grown from wild tree cuttings.
