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.
For bottled spirits over 100 mL containing no solids, actual alcohol content is allowed to vary within 0.15% of ABV stated on the label. Alcohol proof in the United States is defined as twice the percentage of alcohol by volume. Consequently, 100-proof whiskey contains 50% alcohol by volume; 86-proof whiskey contains 43% alcohol.
