Black tea Black tea Black tea is a type of tea that is more oxidized than oolong, green, and white teas. Black tea is generally stronger in flavour than the less oxidized teas. All four types are made from leaves of the shrub (or small tree) "Camellia sinensis." Two principal varieties of the species are used – the small-leaved Chinese variety plant ("C. sinensis" var. "sinensis"), used for most other types of teas, and the large-leaved Assamese plant ("C. sinensis" var. "assamica"), which was traditionally mainly used for black tea, although in recent years some green and white teas have been produced.
Camellia taliensis is the tea variety traditionally cultivated in Yunnan. Like "C. sinensis, C. taliensis" contains both theanine and caffeine. "C. talensis" can be easily crossed with "C. sinensis," and the resulting crossbred plants are intermediate between species both morphologically and chemically indicating true hybrids. "Camellia taliensis" is locally used to make white tea, black tea, and pu'er tea. Yue Guang Bai (月光白 "Moonlight White") is a white tea made from the plant. Yunnan pu-erh tea made from "C. taliensis" can command a much higher price than pu'er made from the more common "C. sinensis." Camellia taliensis Camellia taliensis (also Yunnan large
