Alcohol by Volume (ABV) in cider
Alcohol content is the measurement of ethanol content in an alcoholic beverage. In cider constitutes an important quality parameter.
The determination of alcohol by volume with CDR CiderLab is simpler and more rapid than reference method. It consists in a simple photometric reading and operates on a small sample of cider as is without any distillation.
The analysis has a high repeatibility and reliable. The results you obtain with CDR CiderLab are compliant with the results reference analytical methods
Method
Test Principle
Ethanol is oxidized in an alkaline environment through an enzymatic reaction and converted in acetic aldehyde in presence of NAD+, which in turns produces NADH. The increase of the absorbance, measured at 366 nm (end-point) is directly proportional to the concentration of ethanol in the sample.

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