If your wine was served in a smaller glass, would you drink less of it?
That is the question being posed in a study, published in the BMJ, into the growing size of wine glasses.
University of Cambridge researchers found glass size grew from an average 66ml in the 1700s to 449ml today - a near sevenfold increase - and wine drinking nearly doubled from 1980-2004.
"When it comes to how much we drink, wine glass size probably does matter," says study author Prof Theresa Marteau.
The increase in the capacity of wine glasses has been more rapid since the 1990s.
As a regular wine drinker I found that my consumption at home was increasing gradually over a period of time and decided to limit it. At one time one could be buy glasses of 125 ml but these don't appear to be available in the shops so we bought some off the internet.
Pubs and restaurants have stopped selling wine in 125 ml glasses too despite the fact that there is a law obliging them to do so. Which is why now we almost always use cabs if we are going out to a restaurant. On the rare occasions we don't use cabs, I limit my wine to one 175 ml glass, the smallest available. 250 ml seems to be the size that most people order which is a third of a normal bottle.
So I think size does matter, the bigger the glass the more inclined one is to put more wine in.
