Why Doesn't Booze Show Calories on Labels?
The vast majority of beers, liquors, and wines do not have nutrition labels, but though their calories are invisible to the eye, that doesn't mean they aren't there. A pint of your average IPA contains 250 calories. A glass of red wine holds 125. A shot of whiskey has about 100.The secret to these drinks' caloric density is alcohol, which boasts seven calories per gram. That's second only to fat at 9 calories per gram, and much higher than protein or carbohydrate, each of which hold four.
