High-mountain tea or gaoshan tea (Chinese: 高山茶; pinyin: gāoshān chá; pronounced [káu.ʂán ʈʂʰǎ]) refers to several varieties of oolong tea grown in the mountains of central Taiwan. It is grown at altitudes higher than 1,000 metres (3,300 ft) above sea level, and includes varieties such as Alishan, Dayuling, Yu Shan, Wushe, and Lishan.[1] The high humidity and natural precipitation in the high mountain ranges of Nantou and Chiayi Counties make the region a suitable environment for growing tea plants.[1] High Mountain Oolong is a tea that holds all of its original nutrients that are within the unfermented green tea. It does not hold the usual grass-like taste but due to the fermentation process that removes the harsh ingredients, it allows the tea to taste flavorful.[3]
