White tea comes from the delicate buds and younger leaves of the tea plant. These buds and leaves are allowed to wither in natural sunlight before they are lightly processed to prevent oxidation or further tea processing. This preserves the mild flavor of the tea, with almost no astringency or bitterness.
It is called "white tea" because of the fine silvery-white hairs on the unopened buds of the tea plant, which gives the tea a whitish appearance.
White teas tend to be sweeter than green teas, and are low in caffeine and high in catechins and antioxidant polyphenols.
White teas can be infused more than once, providing several cups from one teabag.
