The paper presents analytical parameters of an enzymatic method for alcohol assay in alcoholic beverages by the use of a new kit based on alcohol oxidase and peroxidase catalyzed reactions (AOP). Sensitivity, linearity, accuracy and reliability of the proposed method were tested. It has been shown that results of AOP-assays of alcohol in beers, wines, and strong drinks are in good correlation with those obtained by alcohol dehydrogenase (ADH) method (relations of ADH to AOP values are 0.9197±0.012; correlation coefficient R=0.9983; p<0.0001).
