Tea contains caffeine unless it's been decaffeinated. The caffeine content varies depending on the plant variety and how long the leaves age. Oolong is grown primarily in Taiwan and China. A semi-fermented tea, oolong possesses an earthy flavor. If you're looking for a tea that is low in caffeine, oolong makes a good option.

The Tea Total

Oolong tea is low in caffeine compared to other teas like green and black. The content varies based on how long you brew or steep the tea and at what temperature. People commonly brew or steep teas for three minutes for a regular cup and up to five minutes for a stronger cup. It is estimated that oolong tea can contain up to 60 milligrams. Steep or brew for one to two minutes if you prefer a much lower caffeine yield, recommends Sara Perry, author of "The New Tea Book."
