Oolong – wikipedia indigestion heartburn

Oolong ( / ˈ uː l ɒ ŋ/) ( Chinese: 烏龍) is a traditional Chinese tea ( Camellia sinensis) produced through a process including withering the plant under strong sun and oxidation before curling and twisting. [1] 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 8–85%, [2] depending on the variety and production style. Oolong is especially popular in south China and among Chinese expatriates in Southeast Asia, [3] as is the Fujian preparation process known as the Gongfu tea ceremony.

Different styles of oolong tea can vary widely in flavor. They can be sweet and fruity with honey aromas, or woody and thick with roasted aromas, or green and fresh with complex aromas, all depending on the horticulture and style of production. [1] Several types of oolong tea, including those produced in the Wuyi Mountains of northern Fujian, such as Da Hong Pao, are among the most famous Chinese teas.


Different varieties of oolong are processed differently, but the leaves are usually formed into one of two distinct styles. Some are rolled into long curly leaves, while others are ‘wrap-curled’ into small beads, each with a tail. The former style is the more traditional.

The name oolong tea came into the English language from the Chinese name ( simplified Chinese: 乌龙茶; traditional Chinese: 烏龍茶; pinyin: wūlóng chá), meaning black dragon tea (literally crow-dragon tea). In Chinese, oolong teas are also known as qingcha ( Chinese: 青 茶; pinyin: qīngchá) or dark green teas.

The manufacture of oolong tea involves repeating stages to achieve the desired amount of bruising and browning of leaves. Withering, rolling, shaping, and firing are similar to black tea, but much more attention to timing and temperature is necessary. [4]

Tea cultivation in Taiwan began in the 18th century. Since then, many of the teas which are grown in Fujian province have also been grown in Taiwan. [7] Since the 1970s, the tea industry in Taiwan has expanded at a rapid rate, in line with the rest of the economy. Due to high domestic demand and a strong tea culture, most Taiwanese tea is bought and consumed in Taiwan.

As the weather in Taiwan is highly variable, tea quality may differ from season to season. Although the island is not particularly large, it is geographically varied, with high, steep mountains rising abruptly from low-lying coastal plains. The different weather patterns, temperatures, altitudes, and soil ultimately result in differences in appearance, aroma, and flavour of the tea grown in Taiwan. In some mountainous areas, teas have been cultivated at ever higher elevations to produce a unique sweet taste that fetches a premium price. [7]

• Alishan oolong: Grown in the Alishan area of Chiayi County, this tea has large rolled leaves that have a purple-green appearance when dry. It is grown at an elevation of 1,000 to 1,400 metres. There is only a short period during the growing season when the sun is strong, which results in a sweeter and less astringent brew. It produces golden yellow tea with a unique fruity aroma. [8]

• Lishan ( 梨 山) oolong: Grown near Lishan mountain in the north-central region of Taiwan, this tea is very similar in appearance to Alishan teas. It is grown at an elevation above 1,000 metres, with Dayuling, Lishan, and Fusou being the best known regions and teas of Lishan. It is often grown on the extremely rare Taiwanese Mango, a sub-species of the tropical mango tree. Its thin, sturdy branches support the tea vines well and provide good sun exposure.

• Tieguanyin: Muzha Tea Co. brought the tea from Anxi County and developed Taiwan’s own variation of the popular tea on the hills of Muzha area near Taipei. While the techniques they used were similar to Anxi tieguanyin, the tastes have evolved during over a century of development.
