Standard Alcoholic Drink

Picture comparing standard alcoholic drinks

Beer, wine, and hard liquor (distilled spirits) all contain alcohol. The following common alcoholic drinks contain equal amounts of alcohol and are often referred to as a drink or a standard drink:

  • One mixed drink containing 1.5 fl oz (44 mL) of 80-proof hard liquor, such as gin, whiskey, or rum
  • One 5 fl oz (148 mL) glass of wine
  • One 12 fl oz (355 mL) bottle of beer or wine cooler

Proof is the amount of alcohol in hard liquor or distilled spirits. The percentage of pure alcohol in the hard liquor is usually one-half the proof. For example, a 100-proof liquor is about 50% pure alcohol. Thus, the higher the proof, the more pure alcohol the hard liquor contains.
