Wine glass shape determines how much you pour

Washington, Sept. 28 (ANI): A new study has revealed that drinkers unintentionally poured larger servings when their glasses were wider, when the pourers held them in their hands, and when the glassware matched the wine.

For this study, Doug Walker, Laura Smarandescu, and Brian Wansink, recruited 73 students (all of legal drinking age) who drank at least one glass of wine a week.

The students were brought to several different stations and were asked to pour themselves a normal serving of wine. At each of these stations, the researchers manipulated environmental cues to measure their effects.

They used three different types of wine glasses to test the effect of size and shape: Large, Wide, or Standard. To see if participants subconsciously drank more when they anticipated a meal, some stations featured a large or small place setting.

To examine the effects of pouring position, students either poured their wine into a glass they were holding or into glass placed on a table. To examine the visual effects of color contrast, there was either low contrast between the wine and the glass (white wine in a clear glass) or high contrast (red wine in a clear glass).

As the researchers suspected, several environmental cues lead to over pouring. When glasses were wider, participants poured 11.9 percent wine.

The students poured 12.2 percent more wine when they were holding their glasses, compared to pouring into glasses placed on a table. When there was low contrast between the glass and the wine (white wine in a clear glass), participants poured 9.2 percent more wine than when there was high contrast (red wine in a clear glass). (ANI)
