All tea types black, green and Oolong are from the same plant, Camellia Sinensis. It's what happens after their picked that makes the difference.

The picked leaves are withered and dried, but only black tea is completely fermented. Oolong is partially fermented, while green is not fermented at all. These teas enjoy a wide popularity, both for their great taste and for their reputed health benefits. They are created with the addition of select fruit and flower flavors. These teas are excellent hot or chilled, and are enjoyable at any time to satisfy your flavored tea desires.
