Once upon a time, it was totally acceptable to pour unmeasured amounts of Burnett's Blackberry Vodka into a mostly empty Diet Pepsi bottle. But since it's become rather uncouth to wake up on the steps of the NYPL with a raging hangover, it's perhaps wiser to track how much alcohol is in your drink of choice. At least, that's what the government thinks—they've created a "cocktail content calculator" just for you and all the other American lushes!

The National Institute of Health released the calculator recently, which culls bartender recipes for popular multi-ingredient drinks so you can figure out how much booze is in a margarita as opposed to, say, a glass of wine. "Most people don’t realize how much alcohol is actually in a drink,” Dr. George Koob, director of the NIH’s National Institute on Alcohol Abuse and Alcoholism, told the Post.

A standard drink, for instance, is the amount of alcohol in a bottle of beer or a 5 ounce glass of wine—that's about 1.5 ounces of hard alcoholic content. One mojito, according to the calculator, is about 1.2 standard drinks; a pina colada is two standard drinks. You can also use the calculator to calculate the amount of alcohol in your own cocktail creation, if you so desire.

Ah well. We're all drinking too much anyway.
