A new study in BMC Public Health, spotted by Science of Us, examined wine ordering habits at one English restaurant over the course of four months. Every two weeks, the restaurant changed its wine glasses, serving the same amount of wine (6 ounces) in either a smaller-than-average (8.5 ounces), average (10 ounces), or large glass (12.5 ounces).
While it wasn’t clear how smaller glasses affected people’s ordering behavior, large glasses definitely influenced the restaurant’s sales. When wine was served in larger glasses, the restaurant sold 9 percent more each day. Something about drinking out of a big glass made people want to order more.
