A standard drink is equal to:
- 12 oz. (355ml.) of 5% beer
- 5 oz. (125 ml.) of 12% wine
- 1.5 oz (45 ml.) of 40% (80 proof) spirits
We use a standard drink because there’s an equal amount of alcohol in each of these drinks. Each of these drinks will increase your BAC by the same amount.
Now what if you usually drink 3 oz of Vodka or a pint (16 oz.) of beer? How many “standard drinks” is in your usual drink?
First, look at the bottle to see if the % alcohol is listed. Also, how big is it? Beer bottles come in a variety of sizes ranging from 8 to 40 oz.! If the alcohol content is not listed, click here for a list of many beers, wines, wine coolers, liquors and liqueurs and their alcohol content. Scroll down the page and find your drink. The alcohol content will be in the column to the right. Note that .05 = 5%, .40 = 40%. Then enter that information below to see how many standard drinks there are in what you usually drink.
