The expression of a full-bodied red wine as a function of the characteristics of the glass utilized for the tasting

With the aim to better understand how the differences related to the glass type can influence the consumer perception of the wine, the same product was assessed in each glass, at the same moment, for three times (t = 0, 40 and 120 min) during every tasting session. The evolution of wine in each glass was characterized also by a chemical and physical point of view, in order to verify if the different characteristics of the glasses utilized influenced the chemical parameters analyzed, so to justify the changes in the sensorial perception expressed by the panel components. Thanks to the general overlapping between the developments related to the evolution of sensorial, chemical and physical characteristics of the wine, it was possible to define a final classification of the types of glasses utilized and identify which glass seemed to show the best influence on the sensory perceptions of the wine tasted.

Glass and wine: a good example of the deep relationship between drinkware and beverage

ABSTRACT As the choice of the drinkware could deeply affect consumer perception during beverage consumption, an experimental research was carried out by expert testers to investigate the evolution of chemical–physical and sensory profiles of a typical rosé wine maintained in different types of glasses. The aim of this research was to select some parameters to well correlate beverage sensory properties with glass characteristics which can be used for drinkware design. The different sensorial profiles, obtained as a function of the geometric characteristics of glasses, were compared with one another. In order to find any significant parameter useful to represent the time evolution of the wine inside each vessel, the wine poured in all glasses was also characterized at different times from a chemical and physical point of view. As the design parameters are now guided more by aesthetic reasons rather than by functional ones, this new ‘integrated approach’, deriving from the merging of chemical, physical and sensorial data, can be used to design the optimum vessel for the enjoyment of the consumer during assessing sessions. This innovative procedure could be easily adapted for every beverage such as fruit juices, sparkling wines or beer.
