White tea does have caffeine. However, at just 30 to 55 milligrams of caffeine per 8-ounce cup, it contains much less than a cup of black tea, which can contain 60 to 90 milligrams of caffeine, according to Choice Organic Teas.
White tea is made from the immature "buds," or unopened leaves, of tea plants. It typically has a downy appearance due to the presence of tiny hair-like structures on the leaves, which are used by the plant to repel insects. White tea should be steeped in water that is under 190 degrees Fahrenheit for three to five minutes, depending on how strong of a brew is preferred.
