The difference between grape juice and dry red

What is the difference between dry red wine and red wine? Some friends don't know the difference between dry red wine and red wine, so I'm here to make a fool of myself and throw a brick to attract jade. I hope you can tell me what I know so that we can learn together: wine refers to a low-alcohol beverage fermented and aged with pure grape juice. There are many kinds of wine in the world. Generally, wines are classified according to the following aspects: (1) Red wine: fermented grapes with skins, and the wine colors are divided into crimson, bright red and ruby red. In recent years, pink wine is also quite popular in the international market, and its color is between red wine and white wine. 2. White wine: white grapes or red grapes are peeled, juiced and fermented. Pale yellow or golden in color, clear and transparent, with unique typicality. (2) According to the sugar content in wine, 1. Dry wine: also known as dry wine, the sugar in the raw material (grape juice) is completely converted into alcohol, and the residual sugar is below 0.4%. When tasting, it is no longer sweet, only sour and refreshing. Dry wine is the main variety of wine consumed in the world market, and it is also a kind of wine in great demand in China's tourism and foreign trade. Dry wine contains little sugar, so the flavor of grape varieties is fully reflected. The evaluation of dry wine is the main basis for identifying the quality of grape varieties. In addition, the low sugar content of dry wine will not cause yeast re-fermentation, and it is not easy to cause bacterial growth. 2. Semi-dry wine, with sugar content of 4- 12g/L, is widely consumed in Europe and America. 3. Semi-sweet wine, with sugar content of 12-40g/L and slightly sweet taste, is widely consumed in Japan and the United States. 4. Sweet wine: the sugar content of wine exceeds 40 g/L, and it is called sweet wine that can feel sweetness. High-quality sweet wine is brewed from grapes with high sugar content, and the fermentation is stopped before the fermentation is completed, so that the sugar content is kept at about 4%. However, sweet wine is usually fermented and sugar is added separately. China and some Asian countries consume more liqueur. (3) According to 65438, there is no carbon dioxide +0. Still wine: wine without carbon dioxide is still wine. 2. Sparkling wine: The wine containing CO2 is sparkling wine, which can be divided into two types: (1) natural gas wine: CO2 in wine is naturally produced during fermentation, such as champagne produced in Champagne, France. (2) Artificial sparkling wine: CO2 is added to the wine by artificial methods.
