Ti Kwan Yin Tea got its name from a kind of tea cultivar named Ti Kwan Yin (Iron Goddess of Mercy) which is an ideal material for making oolong tea. Grown in the An-xi region of China’s Fujian province, Ti Kwan Yin is the world’s most renowned oolong tea. 10%-50%oxidation results in a tightly wound, uniform tea that is very dense, sage green in color and with what appears to be a light glazing of frost. The art of making Ti Kwan Yin is quite complicated, particularly as the tea nears completion. It is refired one final time at a very low temperature; at this point the most distinguishing feature of the tea (the light glazing of frost) appears.
