Abstract
One of the effects of applying elicitors to plants is an increase in the phenolic and volatile compound content. In this study, grapes treated at veraison with a combination of benzothiadiazole (BTH) and methyl jasmonate (MeJA) were vinified and the volatile composition of the resulting wines was analyzed. The results indicate that the combined application of BTH and MeJA to the grapes led to wines with a similar composition in higher alcohols and esters to wines vinified with untreated grapes, but with a significantly higher concentration of terpenes, with some of these compounds being only detected in wines from treated grapes. The result of a descriptive sensory analysis indicate that these differences in the volatile composition could be detected in wines, those made from treated grapes showing significantly higher fruity notes, aroma and mouthfeel quality.
