TECHNOLOGICAL EVALUATION OF INTRODUCED RED TECHNICAL GRAPEVINE VARIETIES OF THE DON AMPELOGRAPHIC COLLECTION
The results of the technological evaluation of red technical grapevine varieties growing on the ampelographic collection of the institute are shown: Amlahu, Mujuretuli, Megrabuyr, Dimatskun, Rubinoviy Magaracha. These varieties were used to make table samples of wines according classical technology. The studies were carried out in the laboratory of winemaking technology in micro-winemaking conditions. The mass of one batch of grapes was in the range of 7-12 kg. The basic physical and chemical indicators of wort and wine were determined. As a result of organoleptic evaluation, conclusions were drawn on the appropriateness of using these varieties for the production of natural pink and red wines. Cabernet Sauvignon was selected as the control variety. Wine materials from Dimatskun and Ruby Magaracha varieties received a tasting assessment at the control level, which indicates their high potential for the preparation of high-quality wines. The remaining varieties require further study and development of technological methods and processing methods to improve the organoleptic characteristics of wine materials.
