If you prefer white wine, chances are you drink a lot more of it than you think. A new study conducted by Iowa State University finds that when people pour white wine into a clear glass, they pour nine percent more than people who drink red wine. When the glass is especially wide, white wine drinkers pour 12 percent more wine.
Why? White wine blends in with the glass, causing drinkers to pour more than they think they are. It also, of course, has to do with the fact that everyone has a totally different idea about how much wine constitutes a glass.
