carbohydrates in alcoholic beverages

14 gm alcohol The calories in alcoholic beverages come from alcohol, which contributes 7 calories per gram as opposed to 4 calories per gram for protein and carbohydrate and 9 calories per gram for fat. So if you take 7 calories per gram times approximately 14 grams of alcohol per jigger (1 1/2 ounces), this equals 98 calories. If the alcoholic beverage such as a liqueur also contains carbohydrate, then the calories for this beverage will be even higher and you can multiply the grams of carbohydrate times 4 to get the carbohydrate calories.
