p < 0.05). ApCO were perceived as equally pleasant across genotypes (AA: 7.2, SD= 1.1; AG: 7.6, SD=1.0). During the alcohol session, there were no group differences. A significant main effect (F= 7.862,35, p < 0.005) of representativeness (how well subjects thought the aromas reflected their intended sources) indicated that ApCO (7.1, SD= 1.5) were perceived as less representative than AO (8.0, SD= 1.1) or NApO (7.8, SD= 1.0; p's< 0.005), but again without any differences across genotypes.
