Brewing Calculators
Brew better beer with professional-grade calculators designed for homebrewers and craft brewers. These tools handle the complex chemistry and calculations involved in every stage of the brewing process, from mashing and boiling to fermentation and bottling. Whether you're formulating recipes, calculating alcohol content, or ensuring proper carbonation, our brewing calculators help you achieve consistent, high-quality results batch after batch.
10 calculators in this category
ABV Calculator
BrewingCalculate alcohol by volume from original and final gravity. Includes standard and advanced formulas.
Attenuation Calculator
BrewingCalculate apparent and real attenuation from OG/FG, or predict FG from yeast attenuation rating. Includes ABV estimates.
Beer Calories Calculator
BrewingEstimate beer calories from OG/FG or ABV. Breaks down alcohol vs carb calories. Supports oz/ml serving sizes.
Boil-off Calculator
BrewingCalculate boil-off rate, total evaporation, and required pre-boil volume. Work forward from volumes or backward from target rate.
Brix / SG / Plato Converter
BrewingConvert between Brix, Specific Gravity, and Plato. Includes potential ABV estimate at 75% attenuation.
Grain Bill Calculator
BrewingCalculate total grain weight and per-grain amounts for a target OG, volume, and efficiency. Includes SRM color estimate via Morey formula.
IBU Calculator
BrewingCalculate International Bitterness Units (IBU) using Tinseth, Rager, or Garetz formulas. Accounts for hop form, alpha acid, boil time, and gravity.
Priming Sugar Calculator
BrewingCalculate priming sugar (corn sugar, table sugar, DME, honey, maple) for bottle conditioning based on batch volume, temperature, and target carbonation.
Strike Water Calculator
BrewingCalculate strike water temperature and volume for infusion mashing. Accounts for grain weight, temperature, equipment loss, and absorption.
Yeast Pitch Rate Calculator
BrewingCalculate yeast cells needed and packages required based on batch volume, gravity, yeast type, viability, and starter. Supports ale and lager rates.
