The influence of climatic factors on the elemental composition of Feteasca Regala wine from three southern regions

The research targeted the investigation of the aromatic profile for 2019 Feteasca Regala wine resulted from three romanian traditional wineyards: Samburesti, Corcova and Avincis Dragasani. After the liquid / liquid extraction, 42 aroma compounds were identified and quantified by gas chromatography coupled with mass spectrometry (GC-MS), the obtained results differentiating them based on the area of origin and climatic factors. The higher alcohols varyed between 28644.53 µg /L and 33969.27 µg / L, while the esters showed values between 4221.10 µg /L and 7901.25 µg /L. Significant amounts were also observed for fatty acids, between 5310.99 µg /L and 6045.15 µg /L, while lactones showed values starting from 727.39 µg /L and accumulated up to 988.01 µg/L. The most significant results were noticeable in the case of Feteasca Regală wine from Avincis Dragasani, where the climatic indicators were in an optimal ratio, imposing specific quantifiable elements.
