Abstract

The invention relates to the technical field of wine brewing, in particular to a pretreatment method for brewing grape wine by adopting a flash evaporation process and a grape wine. The pretreatment method comprises the following steps: cleaning, checking and preparing the grape wine brewing device; crushing part of grape fruit grains to obtain grape juice; heating the grape juice, mixing the heated grape juice with uncrushed grape fruit particles treated by sulfur dioxide, dipping, and carrying out flash evaporation on the grape fruit particles subjected to heat dipping, so that the grape fruit particles are exploded and boiled in a negative pressure environment to obtain a material subjected to flash evaporation; discharging the condensed water in the brewing device or recovering the condensed water, and then fermenting the flashed material to obtain the wine; remaining materials in the brewing device are treated, and then cleaning the brewing device. According to the method, actual operation can be conveniently guided, stable and efficient operation of the flash evaporation system is facilitated, the production efficiency is improved, and the grape wine quality is improved.

Description

technical field

[0001] The invention relates to the technical field of wine brewing, in particular to a pretreatment method for wine brewing by adopting a flash steaming process and wine. Background technique

[0002] The basic principle of the flash evaporation process is to use the principle of physics. The high-temperature liquid enters the negative pressure state instantly, the boiling point of the liquid decreases, the volume expands and vaporizes rapidly, and the temperature decreases rapidly at the same time, and the condensed liquid is collected at the same time. Compared with the traditional brewing method, the flash steaming process can kill harmful microorganisms, destroy the activity of laccase and oxidase, significantly improve the color concentration and color stability of red wine, increase the body thickness of the wine, and enhance the aging potential, antioxidant capacity and nutrition. The advantages such as value and health care efficacy have broad applica...
