Abstract

The invention discloses an organic green tea manufacturing method which comprises the following steps: preparation of raw materials: selecting tea trees at the altitude of 1,000m-1,100m; tedding fresh buds: tedding the picked fresh buds with the thickness being 5mm-30mm for 8-10h, and being proper when the buds are wither and soft, the color of the buds is deeply green and the buds have faint scent; green removal: removing green at temperature of 380 DEG C to 400 DEG C for 4-5min, and naturally cooling for 5-7min; shaping: shaping at temperature of 250-280 DEG C for 15-20min, and naturally cooling for 15-20min; and drying: drying at temperature of 130-160 DEG C, discharging at drying temperature of 210-230 DEG C, having temperature rate of 3-4 DEG C / min, and fast tedding and cooling to a room temperature, thereby obtaining the organic green tea. By adopting the method, green tea has strong and lasting scent and the manufacturing time of the tea is short.

Description

technical field [0001] The invention belongs to the technical field of tea processing, and in particular relates to a green tea processing method. Background technique [0002] As far as organic green tea is concerned, there are many varieties, but they all have a common defect, that is, low-temperature processing is often used, and the greening time is relatively short. For these reasons, the finished tea has a strong bitter taste and insufficient aroma, and the fragrance does not last long after brewing. Contents of the invention [0003] The purpose of the present invention is to overcome above-mentioned shortcoming and provide a kind of processing method of the organic green tea that the aroma is rich and lasting, and processing time is short. [0004] A kind of processing method of organic green tea of ​​the present invention, comprises the following steps: [0005] (1) Raw materials: select tea trees at an altitude of 1000-1100m; [0006] (2) Fresh buds spread gre...
