Homebrewing
Calculate ABV, IBUs, priming sugar, mash water, and alcohol dilution for homebrewing.
ABV Calculator
Calculate the alcohol by volume (ABV) of your homebrew beer, wine, or cider.
Priming Sugar Calculator
Calculate exactly how much priming sugar to add for perfect bottle carbonation.
IBU Calculator
Calculate the International Bitterness Units (IBUs) of your homebrew recipe.
Mash Water Calculator
Calculate the amount of strike water and sparge water for all-grain brewing.
Alcohol Dilution Calculator
Calculate how much water to add to dilute a spirit or high-gravity beer to your target ABV.
Homebrewing Calculators Guide
Homebrewing is equal parts science and art. The science part — calculating ABV, bitterness, carbonation, and mash water — is where precision matters most. These calculators hold your hand through the technical side so you can focus on the creative part.
Always keep detailed brewing notes. Record your original gravity, final gravity, hop additions, mash temperatures, and fermentation timeline for every batch. Over time, these records become your personal recipe library and help you consistently reproduce your best beers.
