Study: Wine Drinkers Don't Know How Much They Consume

Well, this explains why so many of my tasting pours are really aggressive.

Researchers from Iowa State and Cornell have found that people who drink wine often don't know how much they're consuming.

The Des Moines Register reports:

The study, published in Substance Use and Misuse, found that participants poured 12 percent more wine into a wide glass than a narrow glass. They also poured 12 percent more wine into a glass they were holding, versus one placed on a table. Color contrast affected pours, too. Participants over-poured white wine into a clear glass by 10 percent. There was less over-pouring when the wine was red. 

Even after participants were informed of their habits, they still over-poured, Smarandescu said.
