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

Determination of Fermentable Sugars in beer and wort

In 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.


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.

Calibration Curve

The calibration curve was made using samples with known values of fermentable sugars. The trend of the curve confirms the excellent linearity of the system over the entire measurement range.

The calibration curve of the analysis of fermentable sugars in wort and beer was made using samples with known values of fermentable sugars. R² = 0.9933
