Abstract

The invention relates to a processing method of Taoyuan big leaf dark tea, comprising the following steps: selecting one bud and three leaves or one bud and four leaves of raw material Taoyuan big leaf tea, and carrying out enzyme deactivation till the leaf color is changed into dark green from blue green and faint scent comes out, wherein the enzyme deactivation time is 2-4 min; then rolling till the leaves are in strip shapes primarily for creating conditions for pile fermentation, wherein the foliar cell damage ratio is 30-35% and the strip ratio of tea leaves is more than 90% after rolling, the strip-shaped leaves are rolled tightly, the tea juice is fully overflown and can be extruded out among fingers when grasped with hands tightly, and the pile fermentation after rolling is carried out in a tea leaf pile fermentation cellar; and baking and drying after pile fermentation to prepare a finished product. The processed product takes Taoyuan big leaf tea as raw material, and is refined and prepared through the process steps of enzyme deactivation, rolling, fermentation in pile fermentation cellar, drying and the like. The dark tea is uniform and tidy in shape, dark brown and bright in color, and smells like pine black; the tea water is brilliant red and clear in color and tastes mellow, smooth and sweet. The Taoyuan big leaf dark tea has the characteristic that the longer the age is, the stronger the fragrance is, and overcomes the defects of the traditional pile fermentation that since pile fermentation completely depends on manual operation and experience, the pile fermentation time is long, the middle part of the pile is often over-fermented and the edge of the pile is ofen under-fermented, and the quality is hard to control.
