Quantitative content of phenolic compounds and antiradical efficiency of Kakhethian wines were studied and findings are compared to the appropriate data of the European wines. Analysis showed Kakhethian wines to considerably surpass the European wines with regard to total phenolics compounds: 1,330-2,430 mg/L (Kakhethian white wines), 210-468 mg/L (European white wines), 2,898-4,416 mg/L (Kakhethian red wines), 1,630-2,340 mg/L (European red wines). Average value of antiradical efficiency of white and red wines of Kakhethian type was found to exceed the average value of antiradical efficiency of white and red wines of European type, by 2.3 and 1.7 times, respectively.
