What is the difference between a person that drinks a beer and a person that takes a shot of liquor?

Wine. Beer. Wine cooler. Cocktail. Mixed drink. Different kinds of drinks, different amounts of alcohol, right? Wrong!

It’s a mistake many people make. In truth, standard serving sizes of all alcohol beverages — beer, wine, and liquor — are equal in alcohol strength and effect on the body.

Says who?
The current Dietary Guidelines for Americans, published by the U.S. Departments of Health and Human Services and Agriculture, define a drink of alcohol as “12 oz. of regular beer, 5 oz. of wine, and 1.5 oz. of 80-proof distilled spirits.”

In a survey commissioned by the National Consumers League, respondents said they want more information about alcoholic beverages. Ninety-three percent said they want information on alcohol content, and 87 percent want information on the amount of alcohol per serving.

So, here it is. This fact sheet will help you understand how much alcohol you’re getting, no matter what drink you choose. Knowing the alcohol equivalency of standard serving sizes of different types of drinks is essential to consumers who want to drink responsibly. And experts agree. According to the National Highway Traffic Safety Administration, “Alcohol is alcohol. Beer has the same effect as straight scotch. One 12-oz. beer has as much alcohol as a 1.5-oz. shot of whiskey or a 5-oz. glass of wine.”

How could that be?
One ounce of beer contains less alcohol than one ounce of spirits, but the standard serving of beer is a 12-oz. can or bottle. Here’s how it adds up:

Beer contains between 4 and 7 percent alcohol by volume, with the average being 5 percent alcohol by volume. 12 oz. x 5 percent alcohol by volume = 0.6 oz. of alcohol/serving.
The same is true of wine. The standard serving of wine is 5 oz., which generally contains between 11 and 13 percent alcohol by volume. 5 oz. x 12 percent alcohol by volume = 0.6 oz. of alcohol/serving.
Liquor (distilled spirits) is most often consumed in mixed drinks with 1.5-oz. spirits. Sometimes spirits (vodka, gin, scotch, bourbon, etc.) are mixed with water, club soda, or juice or served “straight” or “on the rocks.” No matter how spirits are consumed, a standard serving (1.5 oz.) of 80 proof (40 percent alcohol by volume) of distilled spirits has the same amount of alcohol as standard servings of beer and wine. So 1.5 oz. x 40 percent alcohol by volume = 0.6 oz. of alcohol/serving.
This means that a typical or standard serving of beer, wine, or spirits each contain 0.6 fluid ounces of alcohol.
