During a typical drinking occasion, how many alcoholic drinks do you consume?

Use the table below to determine the percentages for wine and beer, and the proof of various types of hard alcohol. In Step 3, consider the hours you spent from your first sip to when you stopped drinking.

Enter how many OUNCES of beer or wine you had and how many SHOTS of liquor you had. Be sure to put a check next to all the values you enter. A can of beer is usually 12 ounces and a glass of wine is usually 4 ounces. The proof of hard alcohol can vary based on brand.
