The profile of the phenolic components and features at the beginning of ripening (12.0 - 14.5 °Bx) and at the end of the observation (20.0-22.0 °Bx) of Crimean autochthonous white-berry grape cultivars are studied. The total content of identified phenolic compounds at the beginning of ripening differed depending on the cultivar from 669 mg kg -1 (Sauvignon Blanc) to 2411 mg kg -1 (Kokur Belyi). During the ripening period the content of components in berries of autochthonous grape cultivars decre
