Secondary fermentation process of blueberry fruit wine

Abstract

The invention relates to a secondary fermentation process of blueberry fruit wine. The secondary fermentation process comprises the following steps: raw material sorting, crushing, and pulping; enzymolysis; juice squeezing; freezing concentration; ice yeast main fermentation and fruit wine yeast secondary fermentation; pot pouring, clarification and filtration; ageing; sterilization, cooling and filtration; and storage, filtration and encapsulation. By utilizing a ice yeast main fermentation-fruit wine yeast secondary fermentation technique, the concentration of a dry extract of the blueberry fruit wine is increased, the generation amount of grain oil in a fermentation process is reduced, and the typicality of the finished wine is improved.
