Alcohol Measurement Using Anton Paar Density Meters

The measurement of the alcohol content of alcoholic beverages is indispensable to ensure that the products conform to the label declaration of alcohol content, and to establish the basis for the payment of tax.

Density measurement is officially recognized

An officially recognized method for the determination of alcohol concentrations in alcohol/water mixtures either by weight (%w/w) or volume (%v/v; ABV = alcohol by volume) is the measurement of density followed by conversion into alcohol concentration using official alcohol tables.

Accepted instruments for alcohol determination include pycnometer, hydrometer and Anton Paar density meters.

Pycnometers provide good accuracy, but the method is time-consuming and requires trained personnel to obtain reproducible results.

Hydrometers usually provide less accuracy and require 300 mL to 500 mL of sample, but are easier to use. Careful calibration is necessary.
