The expression “white tea” means that the tea leaves are unprocessed and unoxidized. The leaves are simply dried after picking. A relatively low temperature is used, but since the leaves have not been roasted prior to drying, it’s possible they will become slightly oxidized when dried.
White tea does not go through any other processing, and hence the leaves retain much of their original appearance and nutrients. White tea is therefore richer in antioxidants than other types of tea. Its flavour could be described as mild and delicate.
There are two subcategories of white tea: Silver needles and Bai mudan. The former is of the highest quality and consists of buds covered in white down, whereas the latter is the standard quality white tea consisting of both buds and leaves.
