CDR WineLab® the reliable, complete and fast system of wine analyses

Fermentable sugars analysis in wine and must

With CDR WineLab® the determination of the fermentable sugars in the wine and must is based on the OIV method, but it is easier and faster. In addition, the reagents have a 18-month stability, while those under the OIV method just over 1 month.

CDR made available a new fermentable sugars test, which allows to determine, in addition to the value of glucose and fructose, also the value of sucrose.

CDR WineLab® sugar analysis is based on the reference method OIV-MA-AS311-02.

This analysis can also be performed on wine vinegar.


Test Principle

Redox chemical reaction involved in the determination of fermentable sugars in wine and must

The glucose and fructose present in the sample are determined enzymatically and therefore are not influenced by the presence of the remaining reducing sugars. The Redox reaction is read at 366 nm (end-point) and the value is directly proportional to the concentration of glucose and fructose in the sample.

Reaction involved in the determination of sucrose in wine and must

The sucrose, when present in the sample, is determined enzymatically splitting it into glucose and fructose.

Calibration curve

The calibration curve of CDR WineLab®, obtained using reference methods, confirms the excellent linearity of the system over the whole testing range.
