What Is a Drink?
A standard drink is:
- One 12-ounce bottle of domestic brand popular beer* or wine cooler
- One 5-ounce glass of unfortified table wine or one 2.5-ounce glass of fortified wine**
- 1.5 ounces of 80-proof distilled spirits (a large shot)***
- One 4-ounce glass of liqueur
*Beer ranges considerably in its alcohol content, with malt liquor being higher in alcohol content than most other brewed beverages.
** Wine is typically 6 to 14 percent alcohol. If a wine exceeds 14 percent alcohol, the alcohol content must be displayed on the label. Wines designated as table wines (7 to 14 percent alcohol) are not required to display alcohol content on their labels. Aperitif and dessert wines, which have been fortified to make them stronger, contain 14 to 20 percent alcohol.
***Hard liquor also varies in alcohol content. The addition of mixers (such as water, soda, and juice) does not lower the alcohol content. It dilutes the drink, which can help lower the concentration of alcohol in the body. However, the amount of alcohol in the drink is the same.
Alcohol Content
Proof is a measure of the strength of an alcoholic beverage. In the United States, proof represents the amount of absolute alcohol in distilled spirits. Proof is calculated as the number of parts of alcohol in 200 parts of beverage at 60 degrees.
Under the American system, one "proof" is equal to one-half percent of alcohol by volume. Thus, a standard drink of 80-proof spirits is 40 percent alcohol by volume.
The dose of alcohol contained in a serving of alcoholic beverage is calculated by multiplying the volume of an alcoholic beverage by the percentage of alcohol. For example, 12 ounces of beer that is 4 percent alcohol would have a dose of 0.48 ounces of alcohol.
All standard drinks have about the same dose of alcohol, equal to about one-half ounce of absolute alcohol. Some typical servings of certain alcoholic beverages contain more or less alcohol than a standard drink.
Examples of Drink Equivalence
| Alcoholic Beverage | Amount of Absolute Alcohol | Number of Standard Drinks |
|---|---|---|
| 40-ounce bottle of 8% malt liquor | 3.2 oz. | 6.4 drink equivalents |
| 12-ounce bottle of 2.5% low-alcohol beer | 0.3 oz. | 0.6 drink equivalents |
| 1.25-ounce shot of 151=proof rum | 0.94 oz. | 1.9 drink equivalents |
| 12.5-ounce bottle of 20% fortified wine cooler | 2.5 oz. | 5.0 drink equivalents |
