Wine can be divided into dry type, semi-dry type, semi-sweet type and sweet type. Dry wine is usually called dry red wine and dry white wine. The sugar content in wine is less than 4 g/L, that in semi-dry wine is 4- 12g/L, that in semi-sweet wine is 12g/L, and that in sweet wine is more than 45g/L. ..
Expanding knowledge: What are the characteristics of dry wine?
1. Dry wine is also called dry wine. The sugar in the raw material (grape juice) is completely converted into alcohol, and the residual sugar content is below 0.4%. When tasting, it is no longer sweet, only sour and refreshing.
2. Dry wine is the main wine variety consumed in the world market, and it is also a kind of wine that is 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.
3. In addition, because of the low sugar content, dry wine will not cause yeast re-fermentation, and it is not easy to cause bacterial growth.
4. Temperature is one of the important factors for storing dry wine, and it is equally important to keep the temperature stable. The composition of wine will be affected with the change of temperature, and the cork will expand with the change of temperature, especially the cork with poor elasticity, which will expand after a long time. Most wine cabinets are equipped with heaters or PTC to raise the internal temperature, so that the temperature can be kept stable no matter how the ambient temperature changes. The air in the cabinet is also guaranteed by the built-in fan to ensure the uniformity and consistency of temperature distribution in different positions in the wine cabinet.
