Experimental data on the concentration of phenolic compounds in classical Vitis vinifera grapes and hybrid varieties growing in various soil and climatic zones of the Krasnodar Territory are presented. It has been shown that the technological stock of phenolic compounds varies widely – from 5420 to 7360 mg / dm3, depending on the grape variety and the place of its growth.
