How much caffeine inwhite tea?

Yes, white tea contains caffeine, as does any type of tea from the tea plant (including green tea, black tea, oolong, and Pu-erh).

It is a widespread myth that white tea is lowest in caffeine among teas. There is no basis for this statement, and it has been repeated by many companies promoting white tea as a "healthier" product relative to other types of tea.

Scientific studies that have examined the caffeine content of a large number of teas have found that white tea, like other types of tea, has a broad range of caffeine content, from low to high. All tea has much less caffeine than coffee. But the caffeine in a particular tea depends more on the type of leaf used than the way the tea is processed. Teas containing more tips contain more caffeine, whereas teas containing more whole leaves have less caffeine.
