From the perspective of division of the brewing process, which is part of fermented wine class (traditional craft into fermentation, distillation, blending, etc.). When brewing wine, grape skins and grape while squeezing the meat, the red pigment contained in red wine, grape skin is pressed when released. Therefore, the color of red wine is always bright red, crystal clear. The brewed white wine, only do not need to press flesh with the grape skins for brewing, and its color naturally, perfectly clear white light. Wine of the brewing process First, the first is to stem, that is, the grape berry from the comb-shaped Roach’s taken down. Particularly because of Roach’s contains tannins, the wine has an unpleasant taste. Second, squeezing fruit. When brewing wine, grape skins and grape while squeezing the meat, the red pigment contained in red wine, grape skin is pressed when released. Because of this, all the color is red wine. Third, the juice and fermentation. After juice, can be produced wine – grape juice. With wine, juice can be brewed wine. Wine is a product derived by fermentation. After fermentation, the sugar contained in grapes will gradually turn into alcohol and carbon dioxide. Thus, in the fermentation process, the less and less sugar, and alcohol is increasing. Through the slow fermentation process can spawn aromatic taste fine red wine. Fourth, add sulfur dioxide. To maintain the wine’s fruity and fresh, it must be added immediately after the fermentation process, sulfur dioxide treatment. Sulfur dioxide can block the oxygen from the air caused by the oxidation of the wine. New wine in about 3 weeks after fermentation, must be changed first and bucket precipitation. Second precipitation to 4-6 weeks. Precipitation on the frequency and duration of the order is to be achieved entirely taste. Fifth, the wine stored in barrels in three to nine months later, it is necessary bottled. Previously, wine bottles with cork (mostly oak plug) to seal, and now (since 2001) a lot of technological innovation have adopted the new bottling plant rotary vacuum seal the bottle.
