White Tea
It is an unfermented tea made from very young tea leaves or buds that are steamed immediately after harvest to inactivate polyphenol oxidase and then dried. Consequently, white teas usually contain higher concentrations of catechins than other teas. Tiny silver hairs that cover the buds give the tea a white appearance. White teas are the rarest in the world, produced on a very limited scale in China and Sri Lanka. Traditionally plucked only at daybreak in four provinces of north east Fuijan, so that the buds are unopened.
