Beer (Alcohol content: 4%-6% ABV generally) and Wine (Alcohol content: 9%-16% ABV) are alcoholic beverages produced by fermentation. Beer is generally composed of malted barley and/or wheat and wine is made using fermented grapes. The above two have low alcohol content.
The concentration of alcohol in a beverage is usually stated as the percentage of alcohol by volume (ABV, the number of ml of pure ethanol in 100 ml of beverage) or as proof. In the United States, proof is twice the percentage of alcohol by volume at 60 degrees Fahrenheit (e.g. 80 proof = 40% ABV).ne standard drink always contains the same amount of alcohol regardless of serving size or the type of alcoholic beverage. The standard drink varies significantly from country to country. For example, it is 7.62 ml (6 grams) of alcohol in Austria, but in Japan it is 25 ml (19.75 grams).
