Brewing Tools & Calculators
Free, practical calculators for every batch — measure your ABV and bitterness, prime for perfect carbonation, hit your mash temperature, predict your beer's colour, and convert Brix to gravity.
ABV Calculator
Turn your original and final gravity into alcohol by volume and apparent attenuation — the two numbers that tell you how strong your beer is and how far the yeast fermented
IBU Calculator
Estimate hop bitterness in IBU with the Tinseth method — add each hop's weight, alpha acid, and boil time alongside your batch volume and wort gravity for the total
Priming Sugar Calculator
Work out the exact grams of corn or table sugar to prime with — enter your beer volume, target carbonation, and temperature for perfect bottle conditioning every time
Strike Water Calculator
Find the strike water temperature and volume to hit your mash rest first time — from your grain weight, grain temperature, target mash temp, and water-to-grain ratio
SRM Color Calculator
Predict your beer's colour in SRM from the grain bill using the Morey equation — add each malt's weight and Lovibond with your batch volume to see the shade and a preview
Brix to Gravity Calculator
Convert refractometer °Brix readings to specific gravity and back — keep your hydrometer and refractometer measurements in step across every wort reading
