Oolong tea category is the widest and most versatile category of tea. Just like all real types of tea, oolong tea is made from the leaves, buds and branches of camellia sinensis plant. Oolong tea falls between green and black tea, with oxidation rate anywhere between around 10 to 90%. Some oolong teas may be almost fully oxidized, making them very close to black tea, while others are green and light. Unlike green tea, oolongs can contain full branches with leaves and buds. Flavor ranges from light floral tones to cinnamon, toasted bread, ripe fruit, and caramel notes.
