Oolong

Oolong tea is a semi-fermented tea that's a cross between green and black tea in terms of oxidation and flavor: Production Oolong tea leaves are plucked from the Camellia sinensis plant, withered, rolled to break down cell walls, crushed, and fermented for a short time. The leaves are then dried over fire or in an oven. Appearance Oolong tea leaves can be rolled, twisted, or curled into balls or thin strands. The color of the leaves and brewed tea can range from green to golden to brown, depending on the oxidation level.
