The number of calories in alcohol or liquor (gin, rum, scotch, vodka, whiskey) depends on the proof (alcohol content) of the liquor.
On average, 70 proof liquor (35% alcohol) has 85 calories per shot (1.5 ounces).
This is approximately 55 calories per ounce.
On average, 80 proof liquor (40% alcohol) has 100 calories per shot (1.5 ounces).
This is approximately 65 calories per ounce.
On average, 90 proof liquor (45% alcohol) has 115 calories per shot (1.5 ounces).
This is approximately 75 calories per ounce.
On average, 100 proof liquor (50% alcohol) has 130 calories per shot (1.5 ounces).
This is approximately 85 calories per ounce.
The greater the proof (alcohol content) of the liquor, the more calories per ounce. For an easy way to estimate the number of calories per ounce of liquor, subtract 15 from the proof.
80 proof liquor
80 – 15 = 65 calories per ounce
