Brewing
Homebrew calculators for beer makers: ABV, IBU bitterness, priming sugar, strike water temperature, mash efficiency and Brix to gravity, with the brewing formulas shown.
ABV Calculator
Calculate beer ABV, apparent attenuation and rough calories from original and final gravity. Free homebrew tool with the ABV formula shown.
Brix to Gravity Calculator
Convert between Brix and specific gravity for brewing. Enter a refractometer Brix or a hydrometer gravity and get the other. Free homebrew tool.
IBU Calculator
Calculate IBU bitterness for a hop addition with the Tinseth formula. Enter alpha acid, grams, boil time, volume and gravity. Free homebrew tool.
Mash Efficiency Calculator
Calculate mash and brewhouse efficiency from your original gravity, batch volume and grain bill. Set the grain PPG yield. Free homebrew tool.
Priming Sugar Calculator
Calculate the corn sugar needed to bottle-carbonate beer to a target CO2 level. Accounts for residual CO2 from beer temperature. Free homebrew tool.
Strike Water Calculator
Calculate mash strike water temperature and volume with the Palmer formula. Enter grain weight, mash ratio and temperatures. Free homebrew tool.
