Abstract

The invention discloses a white tea processing method. The method comprises the steps as follows: single buds of tea trees are picked, one-bud-for-one-leaf fresh leaves are taken as a raw material, and 0.5-4 cm of short stems of fresh leaves are reserved; the fresh leaves are spread flatly for withering in a room at the temperature of 15-28 DEG C and at the humidity of 50%-70%; then, the leaves are placed under the sun just rising in the morning or the sun at sunset in the afternoon for airing; the leaves are transferred to a room at the temperature of 15-25 DEG C and at the humidity of 70%-80% and collected with screens, every two screens are combined into one screen, and breeze ventilation is performed once every other 2-4 h under the screens; airing is performed for the second, third, fourth and fifth times until the tea leaves have no fresh smell and have natural flow fragrance; and low-temperature slow roasting is carried out until the moisture content is smaller than or equal to8%, and white tea is obtained. Different from a common white tea preparation technology in the prior art, the special white tea processing method can keep nutrient ingredients and microelements in tealeaves, is beneficial to formation of the unique flower fragrance flavor and can realize new taste characteristics of the white tea.
