Refractometer ABV/Brix Calculator

Fine-tune this factor using a completed bone dry batch where you know the exact sugar additions or tested with a Hydrometer. Adjust until the calculated ABV matches your expected result from sugar input. The default (1.038) works for most setups, but calibrating ensures accuracy for your specific equipment and process.
💡 Pro Tip: Use the Simple Sugar to ABV Estimator below to verify your expected ABV from total sugar and volume.
