A new alcohol oxidase-peroxidase method of ethanol assay 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). The proposed method is less time-and laborconsuming and allows simultaneous analysis of a series of wine samples.

In accordance with the plan for the development of agriculture of the Russian Federation for 2017-2025. The agro-industrial complex needs to achieve a stable growth in agricultural production, including by increasing the sown area for spring wheat and potatoes, using new domestic varieties of seeds and improving cultivation technologies. An important task facing agricultural producers is the import substitution of basic food products with domestic products and the use of Russian-bred seeds instead of foreign ones. Over the past 2019, the area under grain crops increased by 101.2% against the level of 2018, including under spring wheat crops by 34.1%. Due to the cultivation of potatoes on personal and peasant farms, the production area under potatoes decreased by 63.3% compared to 2018.
