Oolong is a tea tree tea that is something between green and black tea in terms of production process.
 Oolong tea is made from young leaves of the tea tree, which are fermented, but not for as long as black tea. This gives oolong its unique flavor and aroma, which is often described as fresh, fruity, or floral. Oolong comes in many different varieties, each with its own unique flavor profile. This tea is also a good source of caffeine.
 Preparation: Pour 2-3g of tea (approx. teaspoon) with hot water (85-95 degrees Celsius) and let steep for 3-5 minutes.
