University of Cambridge researchers detected glass size grew from an average 66 ml in the 1700 s to 449 ml today – a near sevenfold increase – and wine boozing nearly doubled from 1980 -2 004.
“When it comes to how much we booze, wine glass size probably does matter, ” says learn writer Prof Theresa Marteau.
The increase in the capacity of wine glass has is becoming more rapid since the 1990 s.
The researchers think one reason for this could be that the demand for larger glasses by the US market was met by an increase in the size of glass stimulated in England.
‘Highly plausible’
Pubs generally sell wine in measures of 125 ml, 175 ml and 250 ml.
Wine writer Jancis Robinson is one of those who believes that larger glass and higher consumption are likely to go hand in hand.
“I have long been a critic of the 175 ml wine glass, ” she says.
“Not just because it encourages people to drink more than they intended, but likewise because white and pink wines tend to warm up in them, encouraging people to finish their contents before they get too warm to be refreshing.”
But a British Beer and Pub Association( BBPA) spokesman told the BBC that pub must give smaller measures so that customers had a choice.
Prof Marteau says that in the same behavior larger plates intend people feed more, indication indicates a similar consequence for wine glasses, although the researchers could not prove this.
“We speculate there are two main mechanisms: capacity – the larger a container, the more we pour into it, and perceptual – the same amount appears smaller in a larger container than a smaller one, ” she says.
“Given we often regulate our intake in divisions such as one slice of cake or one cup of coffee, if we perceive we have not had a full glass of wine, this might lead to us having another glass.”
