Studies have shown that grape pomace is a promising raw material for the functional drinks production with an increased phenols mass concentration. At the same time, the highest mass concentration of phenols was determined in red frape varities pomace. The highest mass concentrations of flovanols were found in white pomace, flavonols in muscat, phenolic acids in red pomace. The mass concentration of oligomeric forms in phenols does not differ significantly in all samples. The highest mass concentration of polymers in phenols is determined in the red pomace. The anthocyanin profile corresponded to the Western European ecological-geographical group grape varieties. Highest mass concentration was determined monoglycoside malvidin.
