Problems solved by technology

However, the problems in these studies are: 1. The raw materials need to be manually deastringent, which reduces the quality of the persimmon fruit; 2. Adding sucrose reduces the aroma of the persimmon wine itself; It will cover the aroma of the wine body itself; 4. There is no feasible method for the later stability research of the wine body
Another reason that perplexes the development of persimmon wine is that the brewed persimmon wine has poor stability, easy to form sediment or suspended matter, and has a short storage time.
However, the existing research is only on the traditional clarification method, and there is no research on the combination of the new clarifier and the stabilization process in the persimmon wine.

Abstract

The invention discloses a method for brewing persimmon ice wine. The method comprises the following steps: 1) selecting fresh persimmon fruits with the same maturity, packaging into sterile freshening bags, and arranging tidily according to demands; 2) putting the packaged persimmon fruits into a refrigeration house, freezing for 10-12 hours at minus 5-8 DEG C, subsequently raising the temperature to be 2 DEG C, standing for 10-12 hours, repeatedly freezing twice in such a manner, wherein the detected sugar content of the persimmon fruits is greater than 240g / L, under the condition that the temperature is not greater than 2 DEG C, crushing and juicing the persimmon fruits by using a presser, and meanwhile, adding sulphurous acid at the amount of 80-100g / t; 3) adding pectinase and cellulose; 4) adjusting the pH value of the persimmon juice to be 4.0; 5) adding activated dry yeast; 6) terminating fermentation; and 7) fining. The method for brewing the persimmon ice wine takes persimmon as a raw material, the persimmon ice wine is brewed by using a fermentation method, and the brewed wine is yellowish in color, pure and harmony in fragrance, tender in taste, clear and transparent, and good in stability.

Description

technical field [0001] The invention relates to a brewing method of persimmon ice wine. Background technique [0002] There are few studies on the technological operation of persimmon wine. The reason is that persimmon itself is not easy to store and transport, and fresh persimmons grown in my country are relatively astringent and need to be processed before they can be eaten. It is recorded in the literature that the earliest brewing of persimmon wine was brewed by the alcohol preparation method. The wine obtained by this method has a heavy alcohol taste and a rough taste; Persimmon juice is mixed and brewed. This method makes the wine often have a strong astringent taste, the wine is too cloudy, and has no typical style; Wang Guiren uses alcoholic fermentation after softening persimmons. The brewing time is about 6 months, and the fermentation cycle is long. Industrial Difficult to operate; Cui Fuxiang shortened the fermentation period on the basis of previous research, a...
