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 amount of alcohol in the finished liquid depends on how much sugar there was at the beginning for the yeast to convert into alcohol. In beer, the alcohol is generally 3% to 12% (6 to 24 proof) and usually about 4% to 6% (8 to 12 proof). Depending on the strain of yeast, wines top out at about 14% to 16% (28 to 32 proof), because that is the point in the fermentation process where the alcohol concentration denatures the yeast.
