[Oxidase-peroxidase method for determination of ethanol in fermented musts and wine products].
A new alcohol oxidase-peroxidase method of determination of ethanol content in fermented musts and wine products is described and compared to conventional methods routinely used in winemaking. The sensitivity, accuracy, and reliability of this method were determined. The results of ethanol determination in fermented musts and wines correlated well with the data obtained by refractometry (correlation coefficient R = 0.9595, p < 0.0001) and densitometry (correlation coefficient R = 0.9384, p < 0.0001). This method is less time- and labor-consuming and allows simultaneous testing a series of wine samples.
