We next compared the characteristic ratings for AcO and AppCo odors in an Odor (2; AcO and AppCo) × Rating (3; intensity, pleasantness, representativeness) linear mixed-effects model, which showed a main effect of Odor (p = 0.003) and Rating Type (p < 0.001), but no interaction (p = 0.73). Follow-up paired t-tests indicated that the alcohol aromas were significantly more pleasant (t = 2.80, p = 0.01) and representative (t = 2.55, p = 0.02) than the grape juice aromas, although the magnitude of these differences was small (mean alcohol pleasantness = 6.54 vs. mean grape pleasantness = 5.65 on a scale of 1-9; mean alcohol representativeness = 7.90 vs. mean grape representativeness = 7.22 on a scale of 1-9). There was no significant difference between alcohol and grape aromas in intensity (t = 1.67, p = 0.11; mean alcohol intensity = 24.60 vs. mean grape intensity = 22.40 on a scale of 1-100).
