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®

Method

Test type: End Point.
Testing time: [uni].
Analysis sessions with multiple samples are possible up to a maximum of 16 tests for CDR BeerLab® and 3 tests for CDR BeerLab® Junior.

Use on beer or wort. The beer sample needs to be degassed using the ultrasonic bath (code 222062) before taking the sample. For higher accuracy in the analysis of wort we recommend to centrifuge (code 222061) the sample. Dilute the sample if required by the method.

Sample treatment

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.

Principle of the test

Chemical reaction involved in the determination of the alcohol content

Samples were analysed for Alcohol using both the CDR BeerLab® and the <a href="/cdrbeerlab/validations/beer-analysis-referencemethods" target="_blank" rel="noopener noreferrer">UKAS accredited gas chromatography (GC) method</a> (Campden BRI Method AM/0 18 based on IOB Methods of Analysis, 1997, 9.10).The international reference analysis laboratory <a target="_blank" rel="noopener noreferrer" href="https://www.campdenbri.co.uk/">Campden BRI</a> 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.”

Samples were tested in the laboratory of <a target="_blank" rel="noopener noreferrer" href="https://www.qclscientific.com/">QCL &nbsp;(CDR distibutor for UK)</a> with the CDR BeerLab® and reference analysis was performed by Campden BRI, innovation, research and technology centre for the food and drinks industry. The table below compares ABV results from the CDR BeerLab® and Campden BRI with the values on the label.

Comparison of ABV results CDR BeerLab® and Campden BRI

The CDR BeerLab® results show very close agreement with the reference method across the range of samples. It is notable from these results that many of the beers have a higher ABV than the packaging suggests. This study demonstrates that the CDR BeerLab® is a reliable and accurate instrument for the measurement of ABV for low and no alcohol beers.
