High Mountain Oolong Tea from Taiwan is also often referred to as high mountain tea or Gao Shan tea.
The name refers to different types of tea which are grown in the mountains of central Taiwan at an altitude of at least 1000 meters above sea level.
High Mountain Oolong tea basically includes slightly fermented teas such as Alishan, Lishan, Da Yu Lin, Shanlinxhi, Milky Oolong and Dong Ding Oolong. The high humidity and natural precipitation in the high mountain regions Nantou and Chiayi make the region a suitable environment for growing tea plants.
The Gao Shan tea leaves are traditionally harvested gently by hand which, due to the high mountain location of the cultivation areas, only wake up very slowly. This only enables a low annual yield.
