How they fool us at the restaurant about wine. One answer comes from a British study, carried out by the Behavior and Health Research Unit of the University of Cambridge, which focused on the size of the glasses used to serve wine in the restaurant: the bigger they are, the more we tend to drink. The study adopted a 300 ml medium glass as a reference. For research, they then considered lower (250 ml) and higher (up to 510 ml) volumes. So – underlines ilfattoalimentare.it which has relaunched the research – the type of glass was related to the data available on sales in certain bars and restaurants between 2015 and 2018.
The results were reported on Addiction. What do they reveal? That, when the glasses are 370 millilitres, the consumption of wine increased by 7.3%, while when they were 250 millilitres, the consumption fell by 9.6%. No differences emerged, however, when restaurants adopt particularly large glasses, of 450 ml and above, just as there was no link between glasses and consumption in bars, probably because in that case the portions are set by the bartender. In short, screwed by the glass. But not always: it depends on “how much” the glass is large. The too Entropia.
