White tea, like other tea types, comes from the Camellia sinensis plant, specifically the tea buds and youngest tea leaves of this plant.  It is the least processed of all teas—the tea leaves are withered to remove moisture and then dried.  White tea has very little caffeine, 1-2% as much caffeine content as one cup of coffee, and brews a light color and flavor.  Loose white teas can be appreciated for their subtlety, complexity, natural sweetness, and delicacy.
