They also suspect a larger glass encourages the brain to drink quicker by fooling it into thinking there is more to get through, even when smaller measures are poured.
Wonder why people seem to be drinking more these days?
Researchers reckon that while cheaper prices, wider availability, and increased marketing likely play a role, the changes in wine glasses are significant too.
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.
Scientists have found that the capacity of wine glasses has ballooned almost seven-fold over the past 300 years, rising most sharply in the last two decades in line with a surge in wine consumption, a study has revealed.
And the biggest glass they found on sale could hold 860ml - enough to take an entire bottle of wine.

There are also 10 special Star Wars wallpapers included (which I am sure will make it onto the various websites before too long). Inside the box is also a special OnePlus/Star Wars greeting card that has a manifesto of the Jedi on it.
They looked at wine glass sizes over the centuries, including a peek at the British royal household's crystal service, and found a steady increase.
Professor Theresa Marteau, who led the research, previously carried out an experiment in which she increased the size of wine glasses at a Cambridge bar, which increased sales by 10 per cent. Similarly, when it comes to food, having larger plates has been demonstrated to increase how much we eat. Just one large glass, by contrast, represents one-fifth of "the weekly recommended intake for low-risk drinking", the report said.
Through a combination of online searches and discussions with experts in antique glassware, including museum curators, the researchers obtained measurements of 411 glasses from 1700 to modern day.
Acclaimed global wine judge and connoisseur Michael Fridjhon said: "Increased consumption figures are the result of more people discovering the joy of wine‚ mainly at the expense of hard tack". "Since the 1990s, the size has increased rapidly".
The researchers said pricing wine according to glass size could reduce how much people drink - but predicted this step would be more popular in January than over the festive season.
In England, wine is increasingly served in 250ml servings with smaller sizes of 125ml often absent from wine lists or menus, despite a regulatory requirement introduced in 2010 that licensees make customers aware that these smaller measures are available.
The scientists, from the Behaviour And Health Research Unit in Cambridge, believe this could be driving consumption rates, which increased nearly four-fold in Britain between 1960 and 1980, and nearly doubled again between 1980 and 2004.
