The caffeine content and antioxidant level is also mid–way between that of green and black teas, making them most healthy and palatable. A very favorite and desired tea amongst connoisseurs, all oolongs hail from either China or Taiwan.

They may be infused multiple (3–7) times, each steep lasting 1–3 minutes. The caffeine content of oolong teas decreases dramatically from the first to the third brew, yielding about 30–50 mg in first the cup, 15–25 mg in the second, and 5–10 mg in the third.

Origins: From lightly oxidized to dark roasted, oolongs can be fragrantly floral to lusciously rich. A special category of minimally oxidized oolong leaves ranges from 6–12% and are known as pouchongs. Taiwan is famous for its many wonderful oolong teas, and deservedly so. Their teas are often named after the particular mountain on which they're grown. In China, Ti Quan Yin ("Iron Goddess of Mercy") is one of the most famous oolong teas whose characteristic flavor is produced in the charcoal firing of the leaves. Ti Quan Yin is a variety of tea plant that produces Ti Quan Yin oolong, and was discovered in the Anxi province of China. Other well–known Chinese oolongs include Huang Jin Gui and Bai Hao.
