Tea is one of the most consumed beverages, second only to water worldwide. It stands out for its taste, aroma, and other benefits. Tea contains large amounts of phenolic substances with high antioxidant properties. Tsalenjikha green tea was selected for the experimental study. Three types of extracts were chosen: deionized water, ethanol and a mixture of ethanol and water (1:1 ratio). The total phenolic content was determined by the Folin-Chocalteu reagent and antioxidant activity by the FRAP method. The results indicate a high polyphenolic index in ethanol and water-ethanol extract. After that, two types of beverages were made by high antioxidant extracts and alcohol with strength 40O. The ratio was 1:4. After mixing, the antioxidant activity was determined in the prepared beverage and the observation of quantitative change continued for a week. Additionally, green tea extract gave different organoleptic properties to Vodka: changed color, aroma and taste according to the extracts.
