Referred to as semi-oxidized, Oolong teas are 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 can range from a greenish yellow to a golden brown. Oolongs are prized for their complex aromas and taste. Greener oolongs offer more floral attributes and darker oolongs often reveal slight fruity characteristics. Some high grade Oolong leaves can even be brewed up to 10 times. It is said that the true tea connoisseur will eventually find oolongs to be their favorite.
