Refractometrical determination of ethanol and extract in wines.Peer-reviewed article

V. ŠVEC

Refractometrical determination of ethanol is based on density and refractive index estimation. Ethanol and extract contents are found in tables or by calculation using these two mutually dependent physical contents. When the precise refractometer is used, the method is equally precise as the pycnometric one but two times quicker. In the opposite case (a less accurate refractometer or densimeter) the method takes less time but the results obtained are very rough.
