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 percentage of alcohol by volume represents the amount of ethanol present within 100 milliliters of the beverage. Most beers contain between 5% to 14% alcohol by volume, give or take. The actual alcohol comes from the fermentation process, where cereal grains like barley, or another starch source, are steeped in water, and a brewerâs yeast is added to trigger the fermentation process.
