Oolong RP: /uːlɒŋ/, GA: /ulɑŋ/ is a traditional Chinese tea (Camellia sinensis) produced through a unique process including withering the plant under the 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 can range from 8 to 85%, depending on the variety and production style. Oolong is especially popular with tea connoisseurs of south China and Chinese expatriates in Southeast Asia, as is the Fujian preparation process known as the Gongfu tea ceremony.
