Oolong tea is a type of traditional Chinese tea that is partially oxidized. It is somewhere in between green tea and black tea, in terms of oxidation level and flavor profile. Oolong tea is typically more floral and fruity than black tea, but less grassy and vegetal than green tea. Oolong tea is often sold in loose-leaf form and can be steeped multiple times for a more concentrated flavor. Some popular varieties of oolong include Tie Guan Yin, Da Hong Pao, and Phoenix.
