According to the national standards of wine, wine is defined as a fermented wine with an alcohol content equal to or greater than 7.0% (VOL), which is fermented in whole or in part by fresh grape or grape juice. When mentioning the alcohol content of wine, many friends may have some doubts. Why do many wines have different alcohol levels?
The fermentation process of wine is a very complicated chemical change, but the most important chemical reaction can be simply expressed as: sugar in the grape + yeast → alcohol + carbon dioxide + heat. Therefore, the alcohol content of wine is mainly determined by the sugar content of the grape fruit. Usually, the alcohol content of the wine is between 7 and 16.2 degrees, because once the alcohol level exceeds 16.2 degrees, the yeast stops moving.
Factors such as climate, grape variety, and year in different countries will lead to differences in the sugar content of the grapes and even the alcohol content of the wine. Too high or low alcohol will affect the taste of the wine: too high will cover the natural aroma of the wine, too low will lead to insufficient wine taste. Therefore, the alcohol content of the wine can be changed by changing the sugar content of the grapes.
