Zusammenfassung
Phenolic compounds include a heterogeneous group of secondary metabolites that play diverse biological functions. Moreover, these compounds play a key role in grape and wine organoleptic and health promoting properties. Therefore, these compounds have been the subject of recent studies aimed at increasing their concentration in both grape and wine. The exogenous application of elicitors, like methyl jasmonate, stands out among these practices. The aim of this study was therefore to evaluate the effect of methyl jasmonate application on the phenolic composition of Tempranillo grape and wine during three consecutive years. The treatment increased the concentration of anthocyanins and stilbenes in grape. Moreover, wine chromatic parameters were also improved.
