The influence of terroir on the sensory characteristics of grapes and wine of the telti-kuruk variety

Unique wines from autochthonous varieties are much more expensive than wines from other varieties. Telti-Kuruk is an autochthonous white technical grape variety, distributed only on the territory of Ukraine. The high quality of the wine is the result of the synergy of the components of the chemical composition of the grapes when reaching technical and aromatic maturity. Sensory analysis of grape quality is a powerful tool for making decisions about harvest and use. The literature does not adequately reflect the influence of terroir on the formation of the organoleptic characteristics of the Telti-Kuruk grape variety using the methodology of sensory analysis. Physical and chemical indicators of grapes showed a significant difference between the clones of different terroirs in terms of titrated acidity; no significant difference was found in the mass concentration of sugar. The mechanical composition of the bunches of grapes confirmed the expediency of using the Telti-Kuruk variety for wine production.
