What is white tea

First, white tea is a kind of slightly fermented tea, which is made from the buds and leaves of baihaoteduo and processed in a specific and delicate way without kneading and frying. The fresh leaves of white tea require "three whiteness", that is, the tender buds and two tender leaves are exposed. Chengcha is full of fluffy hair and its color is as white as silver, so it is called Baicha. White tea can be divided into bud tea (such as Baihao Yinzhen) and leaf tea (such as Gongmei) according to different tea varieties and picking standards. Using single bud as thick material, it is bud tea, which is called silver needle; using complete one bud and two leaves with thick white hairs on the back, it is leaf bud, which is called white peony.
