Calories are probably the last thing on your mind when you're drinking alcohol-containing beverages like beer, wine, distilled spirits or cocktails, but these kinds of drinks are far from being calorie-free.
The dietary information that you can typically get for these products will often list the number of calories per serving, but that serving size is often defined by a "standard drink", which in the United States, is 0.6 fluid ounces (14 grams) of "pure" alcohol, which doesn't necessarily match up with what a customary serving size may be.
For example, a customary size for a serving of beer is a pint (16 fluid ounces), where the standard size for a serving of beer is 12 fluid ounces. In this case, the standard size for beer often matches up with the size of containers in which beer can be purchased for home consumption, but will not if you order a beer at a public venue, such as a bar or tavern, where pints are commonly served, or at a stadium or ballpark, where serving sizes of up to 20-21 fluid ounces may be offered.

If you'd like to estimate the calories in a non-standard size alcohol-containing beverage, we could build a tool for you to do that math (and someday we might get around to taking on that project), but the U.S. government already has one.
