Determination of alcohol content

Spirit producers have to use an alcoholometer in accordance with recommendation R44 (edition 1985) of the International Organization of Legal Metrology (OIML) to determine the alcohol content of their spirits and ethanol mixtures. It determines both the alcohol content expressed as a volume percent and the temperature of the mixture in degrees Celsius. Given that the alcohol content changes depending on the temperature, the strength always has to be given at the reference temperature of 20 °Celsius.
