Determination of Fermentable Sugars in beer and wort

CDR BeerLab is the easy, fast and reliable testing system to be used directly at the brewery with no need of expertise in chemical analysisIn the fermentation yeasts use only fermentable sugars, glucose, fructose, maltose and in some cases maltotriose as well, to produce ethanol. The control of the residual fermentable sugars allows to attest the end of the fermentation and possibly dose the further addition of sugars for a second fermentation in bottle. The analysis of the fermentable sugars is also a very good parameter to determine the fermentative potential of the wort and so the potential alcohol content.
With CDR BeerLab® systems is possible to analyze this parameter in wort and in beer in few minutes. The analysis does not require skilled staff, laboratory glassware nor preparation of reagents: thanks to the instrument and to the optimization of the reference method correlated with it, the analysis is reliable and easy to perform directly in brewery.

Method

Test type: End Point.
Time testing: one test 6 minutes.
Are possible test sessions with several samples, up to 16 tests for CDR BeerLab® and 3 tests for CDR BeerLab® Junior.

Test Principle

The sugars present in the sample are determined through an enzymatic method. The redox reaction is read in end point at 366 nm and the value is proportional to the concentration of fermentable sugars in the sample.

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.

Processing – Sample Volume – Measuring Range

Beer: The beer sample needs to be degassed (we recommend to use an ultrasonic bath) before taking the sample. Wort: Dilute the sample 1:20. For higher accuracy in the analysis of wort we recommend to centrifuge the sample.
