Three olfactometric methods (frequency of detection, time-intensity method, and aroma extractdilution analysis) were used to evaluate the main odorants of three musts obtained from French-Romanian hybrids (Valerien, Admira, and Brumariu). The three methods allow detection of thesame odor-active compounds. The results obtained from these methods were closely related. Nineteenodor-active compounds were detected, and 13 were identified. The three methods showed theimportance of an unidentified compound with a grape and grape juice aroma note in the three musts.Among the other compounds, 3-hexen-1-al, (E,Z)-2,6-nonadien-1-ol, and 1-ccten-3-one seemed tocontribute actively to the odor of Valerien must. 3-(Methylthio)propanal and hexanal werecontributors to the Admira and Brumariu odor. Phenylacetaldehyde was one of the main odor-active compounds in must from Admira.Keywords: Gas chromatography-olfactometry; French and Romanian hybrids; must; odor analysis
