Homebrewing Calculators
Free homebrewing calculators.
Original gravity, IBU, ABV, yeast pitch rate, mash water, and priming sugar.
Beer Color (SRM) Calculator
Calculate the expected SRM color of your homebrew from the grain bill. Predict whether your beer will be pale gold, amber, or black using the Morey equation.
Homebrew ABV Calculator
Calculate alcohol by volume (ABV) from original and final gravity readings. Uses the standard and alternate formulas for homebrewing accuracy.
IBU Bitterness Calculator
Calculate hop bitterness in IBU (International Bitterness Units) using the Tinseth formula. Enter hop weight, alpha acid, and boil time.
Keg Carbonation Calculator
Calculate CO2 pressure (PSI) needed to carbonate your homebrew keg to a target volumes of CO2. Based on beer temperature and target style.
Mash Water Volume Calculator
Calculate mash water and sparge water volumes for all-grain homebrewing. Based on grain weight, water-to-grain ratio, and target pre-boil volume.
Original Gravity Calculator
Calculate expected original gravity (OG) for your homebrew from grain bill. Enter grain weight, extract efficiency, and batch size.
Priming Sugar Calculator
Calculate how much priming sugar to add for bottle carbonation. Enter batch size, desired CO2 volumes, beer temperature, and sugar type.
Yeast Pitch Rate Calculator
Calculate the correct amount of yeast to pitch for your homebrew. Based on wort volume, OG, and yeast type. Avoid under-pitching and off-flavors.
