White wine is usually made from grapes with red skin and white juice or white skin and white juice, which are first squeezed into juice and then fermented separately. Because the peel and juice of grapes are separated, and most of the pigments exist in the peel, white wine is light yellow in color, clear and transparent in body, higher in sugar content than red wine, slightly higher in acidity, pure in taste, sweet and sour, and fragrant in aroma. Red wine is usually made from red grapes. The difference between the two is that when brewing red wine, grape juice and grape skin are processed together, while white wine is only processed with grape juice.
