Abstract

The invention provides a method for improving the quality of a wine. The method comprises the following steps: (1) pressing high-quality muscat grapes to obtain a grape juice, wherein the sugar degree of the grape juice is 180 g/L, and the acidity is 7.0 g/L; (2) clarifying the grape juice obtained in the step (1), performing low-temperature alcohol circulating refrigeration, keeping the grape juice at a temperature of -3 DEG C until frosts are formed in the grape juice, filtering the frost mixture through a screen after the temperature is stable, and separating out ice scum to obtain a concentrated grape juice, wherein the sugar degree is 208 g/L, and the acidity is 8.0 g/L; and (3) adding yeast into the concentrated grape juice obtained in the step (2), fermenting for 18-22 days until the sugar degree is lower than 5 g/L, fining after the fermentation is completed, clarifying, and filtering to obtain a raw wine, wherein the alcohol content is 12%, the sugar degree is 2.2 g/L, and the acidity is 7.0 g/L. The method has the advantage that the wine made from high-quality muscat grapes is subtly fragrant in mouthfeel, transparent in color, mellow and palatable.

Description

A kind of method for improving grape wine quality

Technical field

The invention belongs to grape wine and its technology and brewing technology, more particularly to a kind of side for improving grape wine quality Method.

Background technology

Muscat grape, Eurasia is planted, and is also translated into Mo Sijia, hamburger Moschus, Mu Sikate, mousse card, musk deer Fragrant Maas card top grade.Rose fragrant is an ancient kind, be it is famous in the world eat raw, make wine, juice processed Dual-purpose kind.In the world cultivated area distribution is very wide, and particularly European Countries plantation is a lot.China is in 1871 Year is firstly introduced into Shandong Yantai by American missionary Ni Shi, introduces from West Europe again within 1892, is that China is distributed most There is cultivation in one of wide kind, each main grape place of production, and the country is with the tea in Tianjin Hangu District Cha Dian towns producing region Shallow lake muscat grape is most notable, and has a set of more complete cultivation management technology, while it or a kind of work Name vinifera (domestic well-known grape wine --- --- changyu wine, imperial court's grape wine, magnificent dream Muscat wine The producing region both is from Deng manufacturer's primary raw material).

But all select the grape of inferior quality to cook grape wine due to most of producers, cause the quality of grape wine It is poor.

The content of the invention

The purpose of the present invention is the technological deficiency for prior art, is employed the following technical solutions：There is provided a kind of excellent Matter grape method for preparing medicated wine, comprises the steps：

(1) high-quality muscat grape is squeezed into into grape juice, grape juice pol 180g/L, acidity 7.0g/L；

(2) the grape juice clarification for obtaining step (1), by low temperature alcohol circulating frozen, by grape juice temperature Degree is maintained at -3 DEG C, and frost is formed in grape juice；After temperature stabilization, frost mixture is divided by screen filtration Ice slag is separated out, grape fruitade, pol 208g/L, acidity 8.0g/L is obtained；

(3) the grape fruitade addition yeast fermentation for obtaining step (2), fermented at 18-22 days, pol Less than 5g/L fermentation ends, after fermentation ends after lower glue clarification filtration, former wine is obtained, alcoholic strength is 12 degree, Pol is 2.2g/L, and acidity is 7.0g/L.

It is an advantage of the invention that：Muscat grape using high-quality of the invention, the grape wine fragrant in taste made, Color is bright, aromatic good to eat.

Specific embodiment

Embodiment 1
