Fresh persimmons contain more saccharides such as glucose, fructose and mannitol, and are extremely high-quality raw materials for brewing wine. And the fresh persimmons have short storage period, and are made into persimmon wine, persimmon vinegar, persimmon cakes and the like, so that the nutritional value of the persimmons can be improved, and the great economic value and development and utilization value can be generated.
The liqueur is a beautiful liqueur prepared by taking fermented liqueur, distilled liqueur or edible alcohol as a wine base, adding edible auxiliary materials and food additives, blending, mixing or reprocessing, wherein the reinforced liqueur is generated by prolonging the preservation time at first and then is used for reinforcing the flavor and the alcoholic strength of the fruit wine, and the added highly distilled liqueur can kill saccharomycetes to terminate the fermentation process, so that a plurality of natural components in the wine are not consumed by the saccharomycetes, and finally the reinforced liqueur with high sweetness and alcoholic strength is obtained.
At present, persimmon wine is doped with various auxiliary materials such as white granulated sugar, alcohol, essence and the like in the brewing process, and the persimmon wine has the advantages of unsmooth taste, unclean color and poor wine body balance and influences the flavor of the persimmon wine. Therefore, how to maintain the aroma of the persimmons to the maximum extent and improve the taste of the persimmon wine is a problem to be solved urgently at present.
