The difference between dry white and dry red

Both dry red and dry white wine are relatively famous varieties of wine. But there is still a big difference between dry red and dry white. First of all, let’s talk about its color. The color of dry white wine is clearer, while the color of dry red wine is reddish. There are also big differences in the production process of dry red wine and dry white wine. At the same time, the taste of dry white wine and dry red wine is also different. The following is a detailed introduction to the differences between them.

The difference between dry white and dry red

1. Brewing process: In short, "dry red" is made by fermenting grapes with red skin and white flesh or red skin and flesh with the skin on, fermenting the skin and juice together, and then separating and aging them; "dry white" is made by choosing white grapes or wine grapes with light-colored skin. After the skin and juice are separated, the juice is taken for fermentation and brewing.

2. Color: Since "dry red" is made by fermenting grapes with red skin and white flesh or both red skin and flesh with the skin on, the wine contains colored substances in the skin or flesh, making "dry red" mainly red, and the colors are generally dark ruby ​​red, ruby ​​red, purple red, dark red, brown red, etc.; "dry white" is made from white skin and white flesh or red skin and white flesh grapes that are peeled and fermented, and its color is mainly yellow, mainly nearly colorless, slightly yellow with green, light yellow, straw yellow, golden yellow, etc.

3. In terms of nutritional value: the proportion of vitamin B, riboflavin, niacin, pantothenic acid and pantothenic acid contained in "dry red wine" is higher than that in "dry white wine". In terms of the tasting period, since "dry white" is brewed only with juice, its tannin content is relatively low, while "dry red" is brewed with peel, pulp and juice together, its tannin content is relatively high. Therefore, in general, "dry red" is more stable than "dry white" and has a longer tasting period.

4. Specifically, "dry red" is made by fermenting a mixture of skins (including peels, seeds and stalks) and grape juice, while "dry white" is fermented with clarified grape juice. Therefore, during the fermentation process of red wine, alcohol fermentation and solid matter impregnation occur simultaneously. The former converts sugar into alcohol, and the latter dissolves phenolic substances such as tannins and pigments in the solid matter into the wine. Therefore, the color, smell, taste, etc. of red wine are closely related to phenolic substances.

5. "Dry white" is an alcoholic beverage obtained by alcoholic fermentation of white grape juice. During the fermentation process, there is no phenomenon of grape juice impregnating the solid part of the grapes. In addition, the quality of "dry white" wine is mainly determined by the first type of aroma originating from the grape variety, the second type of aroma originating from alcoholic fermentation, and the content of phenolic substances. Therefore, under certain conditions of grape varieties, the grape juice extraction speed and its quality, the factors affecting the formation of the second type of aroma, and the oxidation phenomenon of grape juice and wine become important technological conditions affecting the quality of dry white wine.

6. Drinking temperature: "Dry red" is more practical. Professionals conducted an experiment and found that the best results can be achieved by tasting red wine at 16 to 18 degrees Celsius; while "dry white" is best tasted in a cool state, that is, at 8 to 10 degrees Celsius, at which time its flavor can be better tasted. Comparing the two, it is clear which one is better.

7. Generally speaking, "dry red" is made from red or purple grapes, fermented by mixing the skin and juice. The pigments and tannins in the grape skins are dissolved in the wine during the fermentation process, so the wine is dark red or red in color, the wine is clear and transparent, has a high sugar content, moderate acidity, and tastes sweet, slightly sour and astringent. "Dry white" is made from grapes with red skin and white juice, or grapes with both skin and juice, which are first squeezed into juice and then fermented separately. Because the skin and juice of the grapes are separated, and most of the pigment exists in the skin, white wine is light yellow in color, the wine is clear and transparent, has a higher sugar content than red wine, a slightly higher acidity, and a pure taste that is sweet and sour and refreshing.
