Abstract

The invention relates to blueberry ice wine and a manufacturing method thereof. The blueberry ice wine is obtained through fermentation brewing by mixed fermentation liquid formed by 62 percent of blueberry juice, 15 percent of bramble juice, 5 percent of strawberry juice, 8 percent of Shuanghongshan grape juice and 10 percent of Vidal grape juice in percent by weight. The invention adopts the blueberry, the bramble, the strawberry and the grape with rich functional ingredients as major raw materials to be fermented after being mixed, and uses the technology such as advanced low-temperature and temperature-control fermentation, pulsed light sterilization and the like to solve the technical problems of high acidity, low color intensity, poor mouth feeling and serious nutrient ingredient loss in the blueberry ice wine brewing process. The products are limpid and transparent, the fruit fragrance is dense, rich and mellow, and the wine is sweet, smooth and tasty, and has the unique features of the blueberry ice wine. In addition, the invention also has the advantages of sanitary, safe and simple operation process, low energy consumption and no pollution.

Description

technical field [0001] The invention relates to a blueberry ice wine and a production method thereof, in particular to a blueberry ice wine and a brewing process thereof, that is, through pretreatment of raw materials, low-temperature pressing, secondary addition of yeast, temperature-controlled fermentation, aging, irradiation sterilization and other processes , to produce a fruit wine with unique blueberry ice wine characteristics. Background technique [0002] The current blueberry wine or wine brewing mostly uses crushing and destemming, and then directly squeezes the fresh fruit. Fermentation at a fermentation temperature above 20°C shortens the fermentation cycle, but the taste, typicality and nutritional components of the product are seriously lost. Ice wine is a development trend of high-end wine in the world. Ice wine must be produced at low temperature, which is a harsh technology. Only a few provinces in Canada, Germany and Austria, which are located at 41-42 degr...
