Wine is an alcoholic drink made from fresh grapes or grape juice through full or partial fermentation, with an alcohol content of not less than 7.0%. It varies depending on the variety of wine produced. Common ones include red wine, white wine, and rosé wine.

Brewing steps:

1. De-stemming: that is, removing the grape berries from the comb-shaped branches and stems. Because the branches and stems contain a lot of tannic acid, they have an unpleasant taste in the wine.

2. Pressing the fruit: When making red wine, the grape skin and grape flesh are pressed at the same time. The red pigment contained in the red wine is released when the grape skin is pressed. Because of this, all red wines are red in color.

3. Juicing and fermentation: After juicing, the raw material for winemaking - grape juice can be obtained. Good wine can be made from grape juice. Wine is a product obtained through fermentation. After fermentation, the sugar contained in the grapes will gradually convert into alcohol and carbon dioxide. Therefore, during fermentation, there is less and less sugar and more and more alcohol. Through a slow fermentation process, red wine with a delicate aroma and delicate taste can be produced.

The difference in making white wine is that it is made from white grapes or red grapes, which are peeled and cored and then pressed and fermented. Therefore, white wine is almost white, with a slightly light green clarification. Transparent liquid.
