Oolong Oolong Oolong (; ) is a traditional semi-oxidized Chinese tea ("Camellia sinensis)" produced through a process including withering the plant under strong sun and oxidation before curling and twisting. Most oolong teas, especially those of fine quality, involve unique tea plant cultivars that are exclusively used for particular varieties. The degree of oxidation, which varies according to the chosen duration of time before firing, can range from 8–85%, depending on the variety and production style. Oolong is especially popular in south China and among Chinese expatriates in Southeast Asia, as is the Fujian preparation process known as the Gongfu tea
Camellia number of "Lepidoptera" species; see List of Lepidoptera that feed on Camellia. Leaves of the Japanese camellia ("C. japonica") are susceptible to the fungal parasite "Mycelia sterile" (see below for the significance). "Camellia sinensis", the tea plant, is of major commercial importance because tea is made from its leaves. The species "C. sinensis" is the product of many generations of selective breeding in order to bring out qualities considered desirable for tea. However, many other camellias can be used to produce a similar beverage. For example, in some parts of Japan, tea made from "C. sasanqua" leaves is popular. Tea
