| Sumario: | The article presents the results of the fruit quality analysis of ten varieties of grapes, selected by National Scientific Centre
‟Institute of Viticulture and Winemaking named after V. Yе. Tairov, that were grown in non-traditional (northern) conditions. In
this paper the influence of weather conditions during the vegetation of 2018–2020 on the terms of technical ripeness of grapes
and accumulation of sugars are determined. The largest amount of sugar content is accumulated in the fruits of the table variety
‘Kishmish tairovskij’ (19.1 g / 100 ml) and among the technical ones – in ‘Aromatnyj’ (18.0) and ‘Ilichevskij rannij’ (18.8 g
/ 100 ml). The fruits of all studied table varieties were characterized by a high concentration of sugars, the glucoacidometric
index range is within 4.2–2.2. ‘Zagadka’ and ‘Kardishah” varieties are characterized by the best taste qualities, ‘Kometa’
and ‘Zagadka’ have the most attractive color of berries and the size of the cluster, ‘Kardishah’ has the nutmeg taste, and
‘Persej’ variety has well-shaped and elegant grapes. Five samples of ordinary wine material with a volume fraction of alcohol
of 9.96-11.28% were obtained after the complete fermentation of the juice of five technical varieties. According to the tasting
assessment, the best wine materials were the varieties ‘Aromatnyj’ (7.78) and ‘Shkoda’ (7.77), which were characterized by
the harmony of taste, and aromatic properties and high scores of the tasting assessment. |
