Though 18th-century wine glasses had an average capacity of 66 milliliters, by the 1900s, the average wine glass held 230 milliliters, and in the 2000s, the average size had ballooned to 416 milliliters.
While most Londoners will be familiar with the experience of paying an arm and a leg for a measly 125ml, it turns out glassware, and the measures we drink from them, are much larger now than in the past. We drank most of our alcohol as beer in the pub, now we drink much of it as wine at home.
"Our findings suggest that the capacity of wine glasses in England increased significantly over the past 300 years", said Zupan.
Wine glasses started to be tailored in both shape and size for different wine varieties, both reflecting and contributing to a burgeoning market for wine appreciation, with larger glasses considered important in such appreciation, they said.
People are boozing it up more than ever and British researchers think they have a handle on one reason why: Wine glasses have steadily gotten bigger.
You've blamed your age, but one glass of wine has made you feel a little tipsier than you reckon it should.
"On top of this, we also have some evidence that suggests wine glass size itself influences consumption".
Combined with an increase in the average strength of wine, the larger glasses mean today's alcohol consumption from wine is likely to be far higher than in the past, researchers said.
The team used measurements of 411 glasses, sourced from museums, the Royal Household and shops, from 1700 to the present day, and found that there were a number of factors over the years - not just glassmaking techniques - that contributed to the increasing sizes in wine glasses. "Since the 1990s, the size has increased rapidly".
Wine consumption increased nearly four-fold between 1960 and 1980, and nearly doubled again between 1980 and 2004, researchers at the University of Cambridge in the United Kingdom said.
"Wine will no doubt be a feature of some merry Christmas nights, but when it comes to how much we drink, wine glass size probably does matter", said professor Theresa Marteau, director of the Behaviour and Health Research Unit at the University of Cambridge, who led the research. Beyond the technological and financial resources that make larger wine glasses possible, plenty of wine aficionados will quickly remind you that a wine glass is not to be filled: The extra room is to let the wine breath.
Now she and Zupan have determined that glass size has slowly increased over the years - and the speed of that increase rose dramatically in the last two decades.
"We predict - with moderate confidence - that, while there will be some resistance to these suggestions, their palatability will be greater in the month of January than that of December", the researchers concluded.
