Determination of Alcohol by Volume (ABV) in Beer

The test allows to measure alcohol by volume (ABV) in beer, which is an important quality parameter.

Features and Benefits of the determination of Alcohol by Volume in Beer with CDR BeerLab®

  • the Method is simpler and faster than reference methods (hydrostatic balance)
  • it does not need specific laboratory facilities, nor the dexterity of chemical analyst experts
  • the results are correlated with the reference methods
  • the test features high reliability and repeatability
  • it has specific calibration for non-alcoholic beers and low alcohol beers


Test Principle

Ethanol, in an alkaline environment, is oxidized through an enzymatic reaction and converted in acetic aldehyde in presence of NAD+, which in turns produces NADH. The increase of the absorbance, measured at 366 nm (end-point), is proportional to the concentration of ethanol in the sample.

Correlation with reference methods

Samples were analysed for Alcohol using both the CDR BeerLab® and the UKAS accredited gas chromatography (GC) method (Campden BRI Method AM/0 18 based on IOB Methods of Analysis, 1997, 9.10).

The international reference analysis laboratory Campden BRI in its report says “Statistical analysis suggested that in the majority of cases and based on current data there is no statistically significant evidence for a difference in alcohol measurements for beer when using the CDR BeerLab® versus the reference methods.”
