A kind of preparation method of environment-friendly tea wine

Abstract

The invention relates to the fields of wine making and environmental protection, in particular to an environment-friendly tea wine preparation method and tea wine obtained through the method. Particularly, no grain soaking step is needed in the tea wine preparation method, and sewage generated in the brewing technique is reduced greatly. More particularly, the preparation method comprises the following steps that 1 grain is provided, pre-treatment is carried out on the grain by adopting a grain-soaking-free method; 2 distiller's yeast is added to the grain pre-treated in the step 1 to generate bacteria grain stillage, the bacterium grain stillage is then cultured for a period of time in a bacterium culture box so that starch contained in grain can be saccharified to generate stillage embryo; 3 tea is soaked and wetted, then the soaked tea or directly selected fresh tea leaves are added to the stillage embryo obtained in the step 2, and the mixture is stirred evenly to generate grain stillage matched with tea; 4 the grain stillage matched with tea obtained in the step 3 is fermented to generate tea wine; if necessary, 5 distillation is carried out on the tea wine obtained in the step 4.

Description

technical field [0001] The invention relates to the field of brewing and the field of environmental protection. More specifically, the present invention relates to an environment-friendly method for preparing tea wine and tea wine obtained by the method. In particular, in the tea wine preparation method of the present invention, there is no need to carry out the grain soaking step, which greatly reduces the sewage produced by the brewing process. Background technique [0002] At present, the brewing process of tea wine has the following problems: [0003] 1. At present, tea wine raw materials (such as sorghum) are rich in tannins, and tannins have a great influence on the saccharification process. If the tannin is exuded without soaking the grain during the brewing process, it will lead to problems such as a lower yield of tea wine, more impurities, and impure wine body. Therefore, soaking grain technology has its importance as an important link in the brewing technology ...

Problems solved by technology

[0004] 2. The tannin rich in grain soaking water will pollute the water body and soil, and the cost of water treatment is high

If the soaked grain water is to be treated to achieve first-class water quality, the treatment cost will be very high, and the water treatment equipment and facilities will occupy land and workshops, and consume a lot of electricity and various treatment salts (such as aluminum salts, copper salts, etc.) , which further makes the production cost of tea wine remain high

[0005] 3. However, if the grain soaking water is directly discharged without water treatment, the water body and soil will be polluted, and the decomposition cycle of the main source of pollution, tannin, may be as long as decades in the natural state, and such tea wine Manufacturers will not be able to pass the EIA

Therefore, if an innovative process can be developed to solve such a volume of pollution sources, its social and economic significance will be immeasurable
