Alcohol is actually the alcohol concentration or content of a wine, and the corresponding expression in English is "AIcohol byVolume", referred to as ABV/abv, which refers to the proportion of ethanol in the wine when the temperature is 20°, and is presented in the form of the product percentage. For example, 15%abv means that 100ml of liquor contains 15ml of ethanol

The alcohol content of different types of wine varies widely, with some sparkling wines having an alcohol content as low as 5.5%abv, while some fortified wines have a high alcohol content of 20%abv. The alcohol content of common wines is generally between 8% and 15%abv
