Oolong tea is the product of a unique variation in processing the tea leaf, and deserves a category to itself. If one considers black tea the most processed of the tea leaf (Camellia sinensis), and green tea the least processed, oolong tea is in between and may be considered “semi-oxidized”. There are many varieties of Oolong due to regional variance in soil integrity, humidity levels, genus and artisanal skill. Crafting oolong tea is an art form and artisans leave their imprint on the delicate leaf. Different varieties of oolong are processed differently, but the leaves are formed into one of two distinct styles. Some are rolled into long curly leaves, while others are ‘wrap-curled’ into small beads, each with a tail.
