Problems solved by technology

High temperature and prolonged maceration will increase the degree of oxidation of the grape juice and bring some inferior tannins into the grape juice. At the same time, too long maceration time will increase the cost and affect the production
Natural fermentation is usually used in the malolactic fermentation process, the fermentation process is difficult to control, the natural fermentation fungi are relatively complex, the product is not clear, and the fermentation period is long, generally 3 to 5 months, and the brewing cost is relatively high

Abstract

The invention discloses a pink wine brewing process, which belongs to the technical field of pink wine brewing; the technical problem to be solved is to provide a pink wine brewing method with low-temperature short-term maceration and short malolactic fermentation time; the adopted technical scheme is: a The rosé wine brewing process includes the following steps: macerating the crushed must at 10-15°C, raising the temperature of the soaked grape serum to 16-18°C for alcoholic fermentation, and controlling the fermentation temperature at 16-18°C; Transfer the alcohol-fermented wine into a malolactic acid fermentation tank, raise the temperature to 18-20°C, add 31MBR of lactic acid bacteria, and stop the fermentation when the malic acid content drops to zero; generally, the malolactic fermentation time of wine is 1-2 months 35 days, the present invention can be completed in about 35 days, which greatly shortens the time for wine brewing; the present invention adopts low-temperature and short-time impregnation, and the quality of the obtained pink wine is higher.

Description

technical field [0001] The invention discloses a pink wine brewing process, which belongs to the technical field of pink wine brewing. Background technique [0002] Rosé wine has a long history. After the Phoenicians introduced the concept of vineyards to France, rosé wine became popular. In the 17th and 18th centuries, rosé wine became the most appreciated wine by European emperors. With the transfer of the wine consumption center to China, the consumption structure of Chinese wine is becoming more and more reasonable. Rosé wine is also becoming popular in the Chinese market. The development of rosé wine in China is booming. [0003] At present, the existing rosé wine brewing method adopts high temperature and long-term maceration during maceration. Usually, the maceration temperature is 20°C, the maceration time is about 36h, and the fermentation temperature is 18-20°C. High temperature and prolonged maceration will increase the degree of oxidation of the grape juice and...
