PERSPECTIVE TECHNICAL FORMS OF GRAPEVINE BRED BY ARRIV&W FOR WHITE WINES PRODUCTION

The results of the technological assessment of white promising technical forms of grapevine bred in Ya.I. Potapenko Institute: 10-30-4-6, 10-30-4-13, 10-30-4-17, which are pointed out by optimal sugar accumulation and suffi-cient juice yield. The research was carried out in the laboratory of winemaking technology in microwinemaking conditions. The mass of one batch of grapes was 5‒10 kg. In the wort of the studied forms, the following indicators were determined: titratable acidity, sugar con-tent, pH value, glucoacidometric index. White dry wine materials were prepared according to the classical technology. In the studied sam-ples of wines, the main physical and chemical indicators were determined. As a result of the organoleptic evaluation, conclusions were drawn about the prospects of using these forms for the production of natural white ta-ble wines.
