This tea is picked from the early spring buds of the Camellia Crassicolumna (厚轴茶) tree, a close relative of tea native to Qianjiazhai. Wild Crassicolumna is very rare and a threatened species. This tea is sustainably harvested from cultivated trees grown from wild tree cuttings. Crassicolumna is naturally caffeine-free and rich in antioxidants. Yabao buds are extremely sweet and packed with flavor since they are the early shoots of the plant that would otherwise become new branches.
