Which one do you need?
- Beer ABV Calculator (OG & FG)
- Work out alcohol by volume from original and final gravity using the simple and extended equations, plus ABW, apparent and real attenuation, and calories.
- Strike Water Temperature Calculator
- Find the strike water temperature and volume that hit your target mash temperature, plus the boiling-water infusion needed for a step mash or mash-out.
- Mash & Sparge Water Volume Calculator
- Work backwards from your target batch size to total brewing water, mash volume, sparge volume and pre-boil volume, with grain absorption and boil-off included.
- Brewhouse Efficiency Calculator
- Compare the gravity points you actually collected against the maximum your grain bill can give, and get mash efficiency, brewhouse efficiency and PPG achieved.
- IBU Calculator (Tinseth)
- Calculate IBUs for every hop addition with the Tinseth utilization model, see utilization by boil time and gravity, and get your BU:GU balance ratio.
- Priming Sugar Calculator
- Work out exactly how much corn sugar, table sugar, DME or honey to prime with, corrected for the CO2 already dissolved in your beer at its current temperature.
- Keg Carbonation PSI Calculator
- Find the CO2 pressure that holds your beer at a target carbonation for any keg temperature, read volumes back from a known psi, and size a balanced beer line.
- Yeast Pitch Rate Calculator
- Work out how many yeast cells your batch needs from its volume and gravity, how many packs that is at your pack's viability, and where one pack leaves you short.
- Refractometer FG Correction Calculator
- Turn a refractometer reading taken after fermentation into true final gravity, ABV and attenuation, using the Terrill equations and your wort correction factor.
- Hydrometer Temperature Correction Calculator
- Correct a hydrometer reading taken warm or cold back to its calibration temperature, and see how many gravity points the sample temperature cost you.
