This presented study sought to determine the qualitative parameters and relationship among the local (Khindogni, Bayanshira, Madrasa, and Shirvanshahi) and internationally introduced (Roussanne, Chardonnay, and Carignane) grapevine (Vitis vinifera L.) cultivars grown in the Mountainous Shirvan Region, Azerbaijan. Few grapevine gardens planted with ancient cultivars remain, which places the wine industry in a difficult position. The local cultivars, Madrasa, Shirvanshahi, and Bayanshira, grown in the Shamakhi Region, Azerbaijan, could provide an incentive for upgrading the wine industry. Consumers abroad prefer wines made from ancient technical grape cultivars. Despite interest in the cultivars Madrasa, Bayanshira, Khindogni, and Shirvanshahi, the technical cultivars Chardonnay, Roussanne, and Carignane ranked first in grapevine cultivation. The various bunch and berry traits were the most studied parameters in these grapevine genotypes. The juice obtained from these berries bore analysis for Brix, pH, acidity, and ripening index. The latest research indicates the wine industry faces the primary challenge of failing to consider the ecological and geographic zonal characteristics of grapevine cultivars. These grapevine genotypes result in the production of low-quality table wines derived from cultivars that are unsuitable for the local soil and climatic conditions. Consequently, about cultivation, cultivars Madrasa, Carignane, Shirvanshahi, and Bayanshira were notably promising cultivars.

Key findings: Based on the bunch and berry parameters and the quality of juice, technical grape (V. vinifera L.) varieties Madrasa, Carignane, Shirvanshahi, and Bayanshira are suitable for growing in the Mountainous Shirvan Region of Azerbaijan. The berry size exhibited a positive correlation with seed weight and a negative with the Brix value of the juice.
