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.
Some liquors will list the alcohol by volume, such as 40% alcohol by volume (ABV).. This would mean that the liquor contains 40% alcohol and 60% water and other components. Many liquors give the alcohol content in both proof and alcohol by volume. A liquor containing 40% ethyl alcohol by volume is 80 proof.
