PRINCIPLE

The determination of the alcoholic content is based on the measurement of the density of a distillate at 20°C. In order to eliminate the other components of wine that modify its density, distillation is carried out so the alcohol is separated and the initial volume is achieved to obtain the same concentration of alcohol in the distillate. The alcoholic content is then measured as well as the temperature of the distillate using an alcoholmeter and a thermometer (instruments and measurement accessories not included) to obtain the correct alcoholic content at 20°C by using the alcoholic tables.
