The way the dark teas are made involves true fermentation. In general, the manufacturing process consists of four major steps: “kill-green”, rolling, piling, and drying. The color of the dry dark tea is black or dark brown and has a slight shine to it. The color of its liquor is bright orange. The aroma is full and pure; the bouquet is floral or holds just a subtle hint of cooked mung bean. The taste is enticing and sweet. The main varieties are Yunnan Pu'er, Shaanxi Fu Brick Tea , Anhua Dark Tea, and Guangxi Liu Bao Tea.
