Min Nan Wu Long is a generic term for the Oolong teas from Anxi and the surrounding areas. It literally means Oolong from the south of the river Min. Large quantities of this type are produced from a number of tea varietals in Anxi and bordering counties. Anxi Oolongs are usually produced in a green manner, the oxidation taking place in rooms chilled through air-conditioning. Normally, the leaves are put into a bag and hit against the floor, in order to remove the oxidized edges of the leaves. The leaves are then alternately fired in heated turning drums and formed to little lumps by putting them into bags on rolling machines. Finally, the teas are dried by hot air in the oven, and sometimes roasted on charcoal. The best known Min Nan Wu Long are the An Xi Tie Guan Yin, but this name is often used for other such teas. A particular specimen of this type of tea is the Zhang Ping Shui Xian, which is shaped into small pillows. Min Nan Wu Long are quaffable, fruity and flowery with sometimes grassy notes. Some of these teas are slightly roasted after the production and obtain heavier, rounder, richer and more fruity notes, while becoming less flowery.
