Red wine sweetness preference according to consumer segmentation

The present work aims to evaluate the acceptance and preference for sweet taste in red wine, according to consumer segmentation in age, gender, personality type, tasting sensitivity and consumer experience in wine. A hundred and fourteen wine tasters were invited to the wine tasting, and the average age was 27 years. An addition of sugar was made with equal concentrations of glucose and fructose to the wine at 2g/L, 4g/L, 8g/L, 16g/L and 32g/L. Five pairs of glasses were presented for the subjects to taste containing each a control wine and a spiked sample. Pairs were presented in order of concentration, from 2g/L to 32g/l. The subjects were also asked to answer two online questionnaires at the end of the tasting, on the personality types and vinotype, which is related to mouth sensitivity. ISO-5495 paired comparison tests were used for sensorial analysis. The objective was to assess if any of the nine segmentation factors had influence on preference or rejection for spiked samples and to establish whether this preference was statistically significant. We concluded that it would be important to have subjects with an age average higher than 27 years and more experienced in wine drinking, mostly because the data relative to preferences in novices shows some dispersion and lack of attention. A panel of older and more experienced wine tasters is likely to be more attentive and focused and therefore yield differentiated results. It was also concluded that more research is required to extend this investigation to other wine styles because the differences in preferences can depend on other reasons, such as preferring a wine with more or less sugar according to the type of wine. Finally it was concluded also that some variables influence preference for sweet taste in red wine, such as gender, vinotype and category of experience
