Referred to as half or semi-oxidized, Oolong tea is made by combining elements of green and black tea processes. After wilting, the usually larger, older leaves are carefully rolled around on rattan trays in order to "bruise" their outer edge. The black outer and green inner parts of the leaf give this tea its characteristic qualities. The liquor is usually a light brown and can sometimes reveal a slight fruity taste. Some high grade Oolong leaves can even be brewed up to 10 times.
