Many people are surprised to learn what counts as a drink. The amount of liquid in your glass, can, or bottle does not necessarily match up to how much alcohol is actually in your drink. They may contain more or less alcohol than a standard drink. That's why it's important to know how much alcohol your drink contains.

What is a standard drink?

One standard drink equals 12 ounces of regular beer, which is usually about 5% alcohol 5 ounces of wine, which is typically about 12% alcohol 1.5 ounces of distilled spirits, which is about 40% alcohol

What is one drink:

a keg (31 gallons, 330 drinks), a fifth (25.6 oz, 25 drinks at 100 proof), a pint (16 oz, 16 drinks at 100 proof), and a wine bottle (25.6 oz, 5 drinks at 10% ABV)
