Problems solved by technology

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 processing white tea using traditional techniques, and lose The original characteristics of the variety are mediocre, which reduces the added value of the product
To process white tea from such resources, it is necessary to maintain the original color of new shoots, and at the same time have the quality characteristics of white tea, which is sweet and mellow without producing fermentation gas. The current production technology is even more difficult to achieve.

preparation example Construction

[0017] For the preparation of large-leaf golden white tea, in order to ensure the quality characteristics of white tea, which is sweet and mellow, and avoid the production of fermentation gas, it is particularly important to control the water loss rate of fresh leaves and the length of withering time. The formation of white tea quality requires a long period of time. Slow oxidation over time, but if the transformation of the contents in the fresh leaves is too slow and the withering time is too long, the taste of white tea will be weak, fermentation gas will be produced, and the production cost will be increased. For this, in the present invention, by controlling air humidity to be 65%~85%, and coordinate with the temperature setting of 14 ℃~18 ℃, preferably, control air humidity to be 70%~80%, control withering time and tea fresh leaf Withering temperature, humidity, as well as water loss rate and withering time can all be beneficial to the formation of white tea quality, achi...

Embodiment 1

[0021] The present embodiment provides a method for preparing white tea from large-leaf yellow tea tree, comprising the following steps:

[0022] (1) Picking: Pick tea leaves that are strong and straight, with one bud and one leaf at the beginning of development, and the leaf color is golden yellow;

[0023] (2) Withering: Put the picked tea leaves indoors and spread them out on a bamboo sieve, control the indoor temperature to 16°C, spread the leaves to a thickness of 1 cm, dehumidify them for 48 hours, and maintain the indoor humidity at 80%; avoid stirring during the period. The stems and leaves of the fresh leaves have a slight prickly sensation, 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 drying temperature of 100°C for 5 minutes;

[0025] Re-drying: After cooling for 30 minutes, re-dry the tea leaves at 75°C for 150-210 minutes to make the water content of the leaves reach 4%-6%, and twis...

Embodiment 2

[0029] A preparation method for white tea, the withering in step (2) is as follows: put the picked tea leaves indoors and spread them on a withering tank, control the indoor temperature to 14°C, spread the leaves to a thickness of 1 cm, and dehumidify them with a dehumidifier for 72 hours, Maintain the indoor humidity at 75%; avoid stirring during the period, until the fresh leaves, stems and leaves have a slight tingling sensation, and the water content of the leaves is below 30%; the rest of the steps, parameters, etc. 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...
