The appearance of wine products with a protected geographical indication (PGI) and with a protected appellation of origin (PAO) gave rise to an urgent issue in the study of the characteristic indicators of the quality of wines depending on the region where the grapes grow. Establishing patterns of changes in various quality indicators of wines with PGI, PAO (color characteristics, cationic-anionic composition, organoleptic descriptor analysis, etc.) in terms of climatic conditions for growing grapes and geographical origin is relevant. The aim of this study was to evaluate the color characteristics of dry white wines with a protected geographical indication. High-quality white wines with Protected Geographical Indication (PGI) produced in the territory of the geographical zones �Kuban. Taman Peninsula� and �Kuban. Krymsk� by the enterprises of OFO �APF �Fanagoria�, OOO �Kuban-Vino�, OOO �Golubitskoe Estate�, AF �Sauk-Dere�, OOO �Lefkadia�. The studies were carried out using laboratory methods of analysis. Intensity (I), shade (N), yellowness (G) were calculated for the instrumental evaluation of the color of the studied white wines, and the CIE Lab color space was also used. The conducted studies have demonstrated differences in the instrumental assessment of color for all indicators of dry white wines with a protected geographical indication, depending on the zone �Kuban. Taman Peninsula� and �Kuban. Krymsk�. Differences in the values of such indicators as the intensity, tint and yellowness of the color within each group of samples, divided by geographical zones, were also observed depending on the content of the total amount of phenols. The use of the CIE Lab color space for assessing the color of wines demonstrated differences in the numerical values of the trichromatic coordinates L*, a*, b*, as well as in color expression.
