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

Determination of Alcohol by Volume (ABV) in vinegar

The test allows to measure alcohol by volume (ABV) in vinegar, which is an important quality parameter.


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. The result is expressed in %v/v.


Calibration Curve

The calibration curve of the CDR WineLab®, obtained by comparing the CDR method with the distillation method for determination of the alcohol content, confirmed an excellent linearity of the system over the entire measurement range.
