Oolong teas are partially fermented (oxidized) Camellia sinensis leaves. Their are green oolongs (about 20-30% oxidized), and black oolongs (about 65% oxidized), signifying how much or how little the oxidization process was allowed to affect the leaves. Due to this tea being a combination greens unfermented, and black teas fermented, it provides qualities of both. Oolong in Chinese, means "Black Dragon", possibly due to the appeaance of the leaves while infusing in water. This tea can be made from smaller young leaves, or larger mature leaves.
