The choice of connoisseurs, oolong tea displays characteristics of both green and black tea. Oolong tea is somewhere in between green and black tea because it is only partially fermented. The leaves are oxidized for 4-5 hours rather than the full 24 hours required to produce black tea.
The flavor profile of oolong tea rests between green and black. Oolongs generally have a crisp, fresh flavor. They are lighter than black tea and often have a floral scent. Oolong tea is often used as an aid with weight loss.
