Beer Calorie Calculator
Calculate the approximate calories in your beer based on the gravity readings. Note: If you plan to add adjuncts, you'll need to account for those separately.
Default is 12 oz (standard bottle/can)
About Beer Calories
Beer calories come from two main sources: alcohol and residual carbohydrates. The alcohol content contributes about 7 calories per gram, while carbohydrates contribute about 4 calories per gram.
How It's Calculated:
This calculator uses industry-standard formulas based on original and final gravity readings:
- Calories from alcohol are calculated based on the alcohol produced during fermentation
- Calories from carbohydrates are calculated from the residual extract (unfermented sugars)
- The total is scaled to your specified serving size
Important Notes:
- This calculation assumes a standard beer fermentation profile
- Adjuncts (fruit, spices, lactose, etc.) will add additional calories not accounted for here
- Actual calories may vary based on fermentation efficiency and yeast strain
- For most accurate results, use precise gravity measurements
Reducing Calories in Your Beer:
- Use highly fermentable sugars to reduce residual carbs
- Employ enzymes to break down complex sugars
- Target lower original gravities
- Ensure complete fermentation with healthy yeast and proper nutrients
