A standard bar pitcher is 60 ounces, which holds 3 3/4 pints of beer at 16 ounces each. Beer ranges in alcohol content from 4 to 7 percent, and the actual serving size of beer varies considerably based on the type of beer.
One serving of a typical, light, 4-percent alcohol beer is 12 ounces. Containers such as pitchers are commonly consumed more quickly than individual servings, creating a higher risk for intoxication when drinking from pitchers. Depending on the bar serving the beer, the size of a pitcher can vary considerably because there is no law governing pitcher size.
