Currently there is no generally accepted definition of white tea and very little international agreement; some sources use the term to refer to tea that is merely dried with no additional processing, some to tea made from the buds and immature tea leaves picked shortly before the buds have fully opened and allowed to wither and dry in natural sun,[citation needed] while others include tea buds and very young leaves which have been steamed or fired before drying. Most definitions agree, however, that white tea is not rolled or oxidized, resulting in a flavour characterized as "lighter" than most green or traditional black teas.
