Determination of Colour in beer and wort
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.
The systems to test Colour in beer and wort
Bitterness levels can be measured using CDR BeerLab®, a system which enables you to carry out a wide panel of chemical analyses on beer and water, using a single instrument, in a process that is faster and simpler than traditional methods.
With CDR BeerLab® brewers and breweries of any size can independently carry out brewing process controls without having to rely on external laboratories.
|CDR BEERLAB®||CDR BEERLAB® JUNIOR|
Beer and Wort:

Vicinal Diketons (VDKs)
Total sulfur dioxide
Free Amino Nitrogen by OPA (FAN)
Lactic Acid (D + L)
Polyphenols in beer
Alkalinity of water
Bicarbonate in Water
Calcium in Water
Zinc in Water

Configuration with tailored panel of analyses
|Simultaneous Sample Analyses||16||3|
|Multiple Analyses on a Sample||–|
Test type: End Point.
Time testing: 1 minute.
Are possible test sessions with several samples, up to 16 tests for CDR BeerLab® and 3 tests for CDR BeerLab® Junior.
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 comparative study of the analytical methods of CDR BeerLab® and the reference methods conducted by the Campden BRI international laboratory
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.
Reagent test Kits
The reagents are packaged in foil pouches containing 10 tubes useful to perform 10 analyses.
This is the minimum package that allows the use of CDR systems even to those who need to make a few analyses, thus not wasting reagents.
There are also boxes of 100 tests, however, packaged in 10 bags of 10 tubes containing the reagent.
Code *300655 – The kit, designed for 10 tests
Code *300650 – The kit, designed for 100 tests
Processing of Sample
Use on beer or wort. Beer or wort samples need to be filtered with the dedicated filter before the reading.
