Alcohol from Hydrometer & Refractometer

Details:  This calculator uses a refractometer and hydrometer reading to ascertain the alcohol content of the sample.  The gravity measurement must be from a hydrometer, and the °Brix measurement must be from a refractometer, these values must not have been calculated from one source.
Alcohol (ethanol) has a higher refractive index than water, so a dry wine will usually give a refractometer reading in the range 5 to 15°Brix.
