Refractometers are a great way to sample gravity, however once alcohol is created during fermentation they will require a few calculations to correct the reading. The calculators below will convert Orignal Brix to Original Gravity (pre fermentation only) and will convert Original/Final Brix to Final Gravity and ABV% (during and post fermentation) without the need to use a hydrometer.
Is 4% about right for a nut brown?
