Grape spirits raw wine production process

Abstract

The invention relates to a grape spirits raw wine production process, which comprises the following steps: removing fruit stems from crystal grapes, crushing to obtain crushed grape pulp, cooling the pulp to below 18 DEG C, naturally soaking for 12 hours, and circularly spraying during the soaking period to obtain grape juice residue mash; then adding active dry yeast FC9 and bentonite diluent subjected to puffing treatment, mixing to obtain a grape juice residue mash mixture, then putting the grape juice residue mash mixture into a fermentation tank for fermentation, and adopting circulating spraying and external circulation to obtain fermented juice; supplementing sugar at a proper time point, then adding a composite fermentation auxiliary agent, immediately separating juice from peel residues after fermentation is finished to obtain fermented raw wine, transferring the fermented raw wine into a stainless steel tank, storing in a full tank, and naturally fermenting for the second time; and finally, adding the bentonite diluent into the secondary fermentation raw wine, standing for 20-30 days for natural clarification, transferring or filtering out supernatant raw wine liquid, and distilling to obtain the grape spirits raw wine. According to the preparation method, the high-quality grape spirits raw wine which is elegant and pleasant in natural fragrance of grapes, smooth, sweet and pure in wine body and extremely little in foreign flavor and peculiar smell can be prepared.

Description

technical field [0001] The invention belongs to the technical field of wine production technology, in particular to the production technology of grape spirit raw wine. Background technique [0002] Grape spirits, also known as grape distilled wines, belong to a large category of fruit distilled wines. They are grape distilled wines distilled from fresh grapes after destemming, crushing and fermenting. It is called "original brandy" abroad. Different fruit distilled wines adopt different fermentation techniques due to the different characteristics of various fruits. There are many types of wine. Under the continuous exploration of winemakers for hundreds of years, many branches of brewing technology have emerged, which endow wine with various rich and complex aromas and tastes, which greatly satisfy people's consumption and experience. . But grape spirits are essentially different from wine, and they are two different types of wine. The yeast, various enzymes, various mate...

Problems solved by technology

[0004] Many grape spirits currently on the market are mostly distilled from low-quality wine, separated skin residue from grape fermentation, and original wine produced by wine technology. The quality of this type of grape spirit is not good, and the pungent smell is strong , with a lot of miscellaneous flavors and high key internal control indicators. In order to make up for these shortcomings, although some improvements have been made in the later stage by human blending, the original aroma and flavor characteristics of grape spirits basically do not exist, and various additional aromas and tastes are varied.
