Example Embodiment

[0017] For the preparation of large-leaf golden white tea, in order to ensure the formation of white tea's sweet and mellow quality characteristics, while avoiding the production of ferment gas, it is particularly important to control the water loss rate of fresh leaves and the length of withering time. The quality of white tea needs a long time. Slow oxidation over time, but if the content of the fresh leaves transforms too slowly and the withering time is too long, the white tea will have a weak taste, produce fermented gas, and increase production costs. Regarding this, in the present invention, by controlling the air humidity to 65%-85% and setting the temperature at 14°C to 18°C, preferably, controlling the air humidity to 70% to 80% to control the withering time and the fresh tea leaves With the water loss rate, the temperature, humidity, water loss rate and withering time during withering can all contribute to the formation of the quality of white tea, achieve the effect ...

Example Embodiment

[0020] Example 1

[0021] This embodiment provides a method for preparing white tea from large-leaf yellow tea trees, including the following steps:

[0022] (1) Picking: Choose tea shoots that are strong and straight, with one bud and one leaf at the beginning for picking, and the leaf color is golden yellow;

[0023] (2) Withering: Put the picked tea leaves indoors and spread them on a bamboo sieve, control the indoor temperature to 16℃, spread the leaf thickness to 1cm, dehumidify the dehumidifier for 48h, and maintain the indoor humidity at 80%; avoid turning it during the period. The stalks and leaves of the fresh leaves are slightly prickly, and the water content of the leaves is below 30%;

[0024] (3) Initial drying: Use a dryer to dry the withered tea leaves at a temperature of 100°C for 5 minutes;

[0025] Re-drying: After cooling for 30 minutes, re-dry the tea at 75°C for 150 min-210 min, so that the water content of the leaves reaches 4%-6%, and the tea leaves are hand twis...

Example Embodiment

[0028] Example 2

[0029] A method for preparing white tea, the withering in step (2) is: putting the picked tea leaves indoors and spreading them on the withering trough, controlling the indoor temperature to 14°C, spreading leaf thickness 1cm, and dehumidifying for 72 hours. Maintain indoor humidity at 75%; during the period, avoid turning until the fresh leaf stems and leaves have a slight thorny sensation, and the water content of the leaves is below 30%; the remaining steps and parameters are the same as in Example 1.

Abstract

The invention provides a preparation method of grandifoliate golden white tea. The preparation method comprises the steps of picking one-bud one-leaf tea leaves from grandifoliate yellowing tea treesor grandifoliate whitening tea trees; spreading the picked tea leaves, avoiding turning over of the tea leaves, controlling air humidity to be 65%-85% and temperature to be 12-18 DEG C, and performingwithering until the water content of the tea leaves is 30% or below; and performing baking. According to the preparation method disclosed by the invention, withering temperature condition and withering humidity condition are controlled and are in mutual coordination and cooperation, so that the water content of the tea leaves and the change speed of the water content are controlled, the witheringtime is controlled to be appropriate, on one hand, leaf blades are prevented from being damaged to cause red discolouration, the processed golden white tea maintains original golden color or lunar white color, on the other hand, the situation that the white tea generates fermentation gas due to long withering time is avoided, and the situation that the white tea has clean, sweet, mellow and briskqualitative characteristics after adequate-time slow oxidization can be guaranteed.

Description

technical field [0001] The invention relates to the field of tea processing, in particular to a large-leaf golden white tea and a preparation method thereof. Background technique [0002] Large-leaf yellowish or albino tea tree varieties are rare resources, and white tea processed from large-leaf yellowish albino tea tree varieties is even rarer. Both the fresh leaves and the bottom of the leaves of white tea have golden yellow or moon white, so they are called gold. white tea. [0003] The processing of white tea by traditional white tea technology often focuses on the quality, forming a smooth and fresh taste of white tea, refreshing or floral aroma, and the shape and the bottom of the leaf are not the focus. One of the reasons why characteristic tea tree resources are so precious is that they are different from the color of shoots of normal tea tree varieties. It is difficult to maintain the original golden yellow or moon white color of fresh leaves during the process of...
