Although white and red wines are made with slightly different raw materials from grapes, the nutritional value is the same. Red wine is a mixture of fermented red grape skins, pulp and juice, with a deep red or bright red color, sweet taste and fragrant aroma. White wine, on the other hand, is made from the fermentation of white grapes or the juice of red grapes, and has a light yellow or golden color, bright liquid crystals, and a pure and refreshing taste. In addition, the wine, there is a "rosé wine", rosé wine made from red grapes, color peach, rose red, wine taste between red and white, close to white wine.

The difference between white and red wine.

One, the brewing process

Simply put, white wine is the choice of white grapes or light-colored skins of wine grapes, after the separation of the skin and juice, the flesh of the fermentation brewing; red wine is the use of red flesh and white or skin and flesh are red grapes with the skin of the fermentation of the skin, skin and juice mixture of fermentation, and then separated from the aging.

So white wine is an alcoholic beverage made from the alcoholic fermentation of grape juice, and there is no maceration of the solid part of the grape by grape juice during the fermentation process. While red wine in the process of fermentation, the alcoholic fermentation and the impregnation of solids are present at the same time. Therefore, the two wines will be different in color, air and taste.

Second, the color

Because red wine is made from red skin and white flesh or skin and flesh are red grapes with skin fermentation, the wine contains the skin or flesh in the colored substances, so the color is generally deep ruby red, ruby red, purple, deep red or brown-red. White wine because of the white skin and white flesh or red skin and white flesh of the grapes peeled fermented, so the color is mainly nearly colorless, slightly yellow with green, light yellow, straw yellow, golden yellow and so on.

Three, nutritional value

White and red wines contain vitamin B, riboflavin, niacin, trans-acid, and Bentosanic acid and other nutrients, but the proportion contained in red wines is a little higher. At the same time, because white wine is brewed with grape juice, the content of tannin is relatively low; while red wine is brewed with fruit skin, pulp and juice together, the content of tannin is relatively high. Therefore, in general, the red wine is a little more stable and has a longer appreciation period.

Four, drinking temperature

In terms of drinking temperature, professionals have done experiments. In 16-18 degrees Celsius when drinking red wine has the best effect, while white wine in 8-10 degrees Celsius when tasting the best effect.

Fifth, taste

Red wine contains more sugar, moderate acidity, sweet flavor, slightly sour with astringent. White wine is slightly higher in acidity, pure flavor, sweet and sour.

In summary, the difference between white wine and red wine lies mainly in the brewing process, color, nutritional value, drinking temperature and taste, you can choose the most suitable for their own wines according to their preferences or the actual situation.
