Tung Ting Oolong is a variety coming from the plantations at over 1,000 metres above sea level in Lugu, Nantou County, Taiwan. The famous mountainous tea is labelled on of the “10 greatest teas from Taiwan”. It is semi-fermented using the tea plant species called ruanzhi (or qingxin), roasted with the highly prized longan wood.
Beside that, processing the tea takes lots of time and effort. A stage unique to making Tung Ting Oolong is to wrap the tea leaves in a cloth, making a sphere and repeatedly rolling and kneading it, so that the finished tea leaves would appear curled up.
