Abstract
The results of a technological assessment of promising red technical forms of grapes bred by ARRIV&W named after Ya.I. Potapenko are presented. These forms (9-8-2-14pk, 8-7-1-5, 8-5-3-18) are distinguished by high sugar accumulation and optimal juice yield. The re-search was carried out in the laboratory of winemaking technology in micro-winemaking conditions. The mass of one batch of grapes was 5–10 kg, in the wort were determined: titratable acidity, sugar content, pH value, as well as the indicator of technical maturity and glucoacidometric indicator. According to the classical technology, red dry wine materials were prepared. In the studied wine samples the main physicochemical indicators were de-termined. As a result of the organoleptic eval-uation, conclusions were made about the ad-visability of using these forms for the produc-tion of natural red table wines. Augusta was selected as a control variety. Wine materials from the studied varieties were distinguished by their typical, dark ruby color, dense struc-ture and harmonious taste. This indicates a high potential of the studied forms.
