Problems solved by technology

Although there are some reports about the blueberry wine brewing method, for example, the patent application number 200610134929.9 discloses a blueberry wine brewing method, but the finished wine brewed by this method has a low sugar content and has a pungent taste on the mouthfeel. Unpleasant sourness, in order to overcome the deficiencies in the prior art, the present invention combines the selection of blueberry raw materials and low-temperature anaerobic fermentation technology on the basis of the traditional blueberry wine brewing method to brew a unique blueberry ice wine, not only Reduced the acid content of traditional blueberry wine, rounded the mouthfeel, and significantly increased the content of a series of volatile aromatic compounds

Abstract

The invention provides a method for brewing wild bilberry ice wine by utilizing complex enzyme enzymolysis and a low-temperature oxygen-free fermentation technology, and belongs to the field of alcoholic beverage preparation. The method comprises the following processes: putting off wild bilberry harvest when the temperature is lower than -5 DEG C, carrying out complex enzyme enzymolysis, carrying out low-temperature oxygen-free pure-bred yeast fermentation under the protection of carbon dioxide, adding blueberry laevulose for secondary fermentation, ending the fermentation according to a physical method, carrying out low-temperature storage with an oak barrel, bottling for storage, and the like. The method has the advantages that the defect that the conventional blueberry wine is thin and highly acid is overcome; and the fruity and the fragrant characteristics are enhanced. Therefore, the wild bilberry ice wine brewed according to the method tastes sweet and intense, has strong blueberry fruity flavor and bouquet, and looks clear and pretty.

Description

technical field [0001] The invention relates to a method for brewing wild blueberry ice wine by utilizing compound enzyme enzymolysis and low-temperature anaerobic fermentation technology, belonging to the field of alcohol beverage preparation. Background technique [0002] Blueberry (Blueberry) scientific name Vaccinium, belongs to the plant of the genus Vaccinium in the family Rhododendronaceae. The fruit is blue in color and covered with a layer of white fruit powder. The flesh is delicate, the fruit tastes sweet and sour, unique in flavor and rich in nutrition. [0003] Blueberry (Blueberry) is a wild deciduous shrub of the genus Vaccinium in the family Rhododendronaceae. It is called blue indigo and bilberry in different producing areas. It can withstand the severe cold of minus 50°C, its roots grow in permafrost all the year round, and its fruits are rich in nutrients. Wild blueberry has high nutritional value and is a rare and rare wild fruit. [0004] According to...
