Beer, wine, and liquor (distilled spirits) are alcoholic beverages. The following common alcoholic beverages contain equal amounts of alcohol. They are often referred to as a drink or a standard drink.
- One 12 fl oz (355 mL) beer or wine cooler
- One 5 fl oz (148 mL) glass of wine
- One mixed drink containing 1.5 fl oz (44 mL) of 80-proof liquor, such as gin, whiskey, or rum
Proof is the percentage of alcohol in an alcoholic drink. The percentage of pure alcohol is usually one-half the proof (for example, 100-proof liquor is about 50% pure alcohol). The higher the proof, the more pure alcohol the drink contains.
