Perfect wine glasses: no go for the ballon and the ISO types
The perfect wine goblet for red wines is shaped like a truncated cone, not to be considered the small glasses or with a round shape
The ISO glass was what was once given to aspiring sommeliers in the welcome kit; I like many others had my first experiences in wine tasting with just those glasses.. On the contrary now Dr. Francesca Venturi and Dr. Angela Zinnai from the Dipartimento di Scienze Agrarie, Alimentari e Agro-ambientali in the Università di Pisa, absolutely advise against. Even the grand ballon similar to a ball, which for years all the Toscana andPiedmont wineries, have bought hundreds of, seems to now be considered not apt for wine tasting.
This research, lasting six months, has now been published by CyTA:Journal of Food, one of the most authoritative scientific magazines. In indicates clearly that the truncated cone shaped glass is the best for appreciating red wines. This is the shape chosen by the Brunello wine as its “official” glass and that many for years have been indicating it as the best, and that now has a scientific consecration based on sensorial evaluations, physical-chemical analysis and the morphologic definement of the glasses.
The 10 experts on the panel tasted the wines in different glasses at 40 minute intervals, for two hours, the usual duration of a dinner. At the same time the evolution of certain chemical physical parameters were measured, such as oxygenation, colour, anthocyanin profile and concentration of the SO2.
The analysis regarded also the morphological characteristics of the glasses, so the aspects such as the rapport between volume in wine and the surface in contact with the air or between the wine surface of wine and the amount that comes in contact with the mouth.
The study commissioned by Bormioli Rocco e Figli company will carry on with glasses for rosé wines including also experts from the Dipartimento di Ingegneria civile e industriale.
Examining this information it is impossible to ignore the distance between the scientific approach adopted in Pisa and the intuitive system used up until now.
In her declaration published by “VQ” Dr Francesca Venturi, concluded saying <<Even though the glass is the means by which the wine communicates with the taster the scientific information able to emphasize the method with which this interaction takes place is scarce.>>
And to think that 4.000 years have passed since the invention of glass and 60 since the creation of the first wine glasses by J. Riedel so as to appreciate the bouquet and the taste of wines. But only now, in Pisa, the first steps towards the scientific knowledge of the rapport between the senses and wine glasses, have finally been made.
