The sun-dried green tea is directly dried by sunlight—the oldest way of desiccation. Sun-dried green tea is mainly produced in Yunnan, Shaanxi and Sichuan. They are named after their respective places of production: Dian Qing in Yunnan, Shan Qing in Shaanxi and Chuan Qing in Sichuan. Mostly compressed as cake tea and Tuo tea (a bowl shaped compressed mass of tea leaves), only a small amount is directly sold for consumption. Processing sun-dried green tea involves: deactivating the fresh leaves, rolling into striations and spreading over bamboo sheets in the sun. The most distinctive feature of this tea is its special sun-dried flavor.
