Red wine is generally 8-15 degrees, and the most common one is about 13 degrees.
Red wine usually refers to wine, which is fermented from grapes. It is a fermented wine, and the alcohol content is not too high. If distilled alcohol is added to the wine, it is a fortified wine, and the alcohol content can reach 22 degrees. .
Wine is made by collecting and crushing grapes, of which there are hundreds of different varieties. Once the grapes are crushed, the natural sugars in the grapes combine with the yeast, causing fermentation to produce alcohol.
Generally speaking, the alcohol content of wine is mostly between 8-15, (the unit of alcohol content is usually or °). It is mainly determined by the sugar content in the grape fruits.
Usually, the alcohol content of wine is between 7 and 16.2 degrees, because once the alcohol content exceeds 16.2 degrees, the yeast stops activity. Although wine fermentation is a complex chemical reaction process, the most important chemical change is the conversion of sugar into alcohol and carbon dioxide under the action of yeast.
That is, fermentation can be simply expressed as:
Sugar in grapes + yeast → alcohol + carbon dioxide + heat. Therefore, if the sugar content of grapes is high, the alcohol content converted into it will be correspondingly high. If the sugar content of grapes itself is low, the alcohol content converted into it will be low.
