Beer

The chromatic characteristics of a beer are defined by its colour which is measured at 420 nm. Even if other ingredients can interfere in the final colour of the beer, the malt is definitely the ingredient that influences most this classification parameter.

Determination of Colour in beer and wort with CDR BeerLab®

CDR BeerLab® - simple, fast and reliable analysis system of beer.

CDR BeerLab®

Readings of absorbance at 420 nm
Time testing: [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.

Method

Use on beer or wort. Beer or wort samples need to be filtered with the dedicated filter (code 300210) before the reading.

Sample treatment

You can carry out the absorbance reading of the filtered beer at 420 nm, properly vialed in the test tube. The analyzer automatically calculates the colour intensity and expresses the result in the most used measuring units: EBC and SRM.

Principle of the test

Samples were analysed for colour using the CDR BeerLab® and the reference UKAS accredited spectrophotometric method (Campden BRI Method AM/028 based on Analytica EBC, 9.6 2000). The curve was obtained as part of the <a target="_blank" rel="noopener noreferrer" href="https://www.cdrfoodlab.com/cdrbeerlab/validations/beer-analysis-referencemethods">comparative study of the analytical methods of CDR BeerLab® and the reference methods conducted by the Campden BRI international laboratory</a>.

Calibration curve

The calibration curve CDR BeerLab® method for color determination and the accredited gas chromatographic (GC) reference method (Campden BRI Method AM / 018 based on IOB Methods of Analysis, 1997, 9.10). R²=0.9994
