Abstract
Georgia, recognized as the cradle of wine and viticulture, preserves an exceptional grapevine gene pool of over 525 autochthonous cultivars, forming a vital foundation for modern breeding programs focused on developing disease-resistant and high-quality varieties. This study reports the preliminary results from 2024-2025 of a complex study including enological, enochemical, and organoleptic characteristics was conducted of three Georgian breeding cultivars - Tabidziseuli, Kakhuri Tetri, and Daisi - selected for their productivity, and enological potential which was selected based on the available information on these varieties. This study aimed to evaluate the ripening dynamics, technological maturity, and enological potential of three Georgian grape cultivars - Daisi, Tabidziseuli and Kakhuri Tetri - over a two-year period 2024-2025. Initial juice sugar concentrations ranged from 18.5-22.5 % values. In the second year, harvest dates were determined individually for each variety according to their specific ripening patterns. The ripening period was observed between March and October 2025. The earliest harvest was completed between September 17 and October 14. Juice yield ranged from 41% to 53%. Sensory evaluation was also conducted for the wine produced from the Daisi cultivar, which revealed its profile characterized by moderate alcohol content, above-average acidity, and below-average tannin levels. These characteristics underline the background information identifying this grape as a suitable cultivar for cold and high-altitude mountain regions. These results provide insights into the phenological behavior and technological potential of local cultivars, supporting their optimal use in differentiated enological approaches and future vineyard management strategies.
