Here are some simplified brewing calculators that may help you when you are brewing.
%ABV Calculator (uses HMRC conversion factors)
Priming sugar calculator (batch prime for bottling)
If cask conditioning, we'd recommend a maximum carbon dioxide volume of 1.4.
If priming a firkin (40.8L approx): 50g table sugar. For a pin (20.4L): 30g. For a 5L minikeg: 18g.
If bottling, use the calculator below.
Dilution calculator (beer OG is too high and you want to lower to a set value)
This calculator will tell you how much additional water you need to add to dilute the wort to the desired OG.
