Where alcohol calories come from
Pure alcohol (ethanol) provides 7 calories per gram, nearly as calorie-dense as fat (9 kcal/g) and considerably more than protein or carbohydrates (4 kcal/g each). This calculation covers alcohol calories only, not calories from sugar, mixers, or other ingredients in the drink.
Worked example
For a 355mL beer at 5% ABV:
Pure Alcohol = 355 x 0.05 = 17.75 mL
Alcohol Mass = 17.75 x 0.789 (ethanol density) = 14.0 g
Calories = 14.0 x 7 = 98.0 kcal
| Drink | Typical ABV | Alcohol Calories (approx) |
|---|---|---|
| Beer (355mL) | 5% | ~98 kcal |
| Wine (150mL) | 12% | ~100 kcal |
| Spirits (44mL shot) | 40% | ~97 kcal |
Remember this figure reflects alcohol calories alone - sweetened cocktails, cream liqueurs, and sugary mixers add significant additional calories on top of this number.
