Sensory attributes of Rioja red wines and their relationship with quality perception of consumers

Résumé

A complex problem in food product is to identify what are the parameters driving consumers’ liking. The main goal of this study was to apply the technique classically used to understand consumer preference, internal preference mapping to the quality assessment of twenty-nine red wine by eighty-five regular consumers. The wines were subjected to a sensory descriptive analysis by trained panelist and to a categorization task by consumers’ preference. Quality assessment was performed by means of a categorization task which was subsequently correlated to the aromatic wine sensory space obtained. The PCA carried out on the wine*consumers matrix showed a wide dispersion in quality perception among consumers. The HCA indicates the presence of three well defined groups of consumers (QC1, QC2 and QC3) Pearson correlation coefficients show no significant correlations between the three groups of consumers indicating a quality concept different between them. The concept of quality of the three groups of consumers when they evaluate wines aged in oak barrels is directly related to the presence of "toasted/wood” and the absence of the veggie/animal attributes. It is noteworthy that only the consumers QC2 considered positive the concept of fruity and floral aromas as quality in a wine barrel aged. Mouthfeel attributes described for these wines were considered in a different way for the quality assessment carried out by the three consumer groups.
