A new study has revealed the shape and color of wine glass influence how much alcohol one wants to consume. Researchers say if the glasses are wider, people tend to pour more wine and over-pour if the color of the glass does not match with the wine’s color.
The study was conducted by researchers from Iowa State and Cornell universities with 73 participants who drank at least one glass of wine each week. All of them were asked to pour the wine themselves into the glass and were stationed at different places set up by the researchers. The findings have been published in the Substance Use and Misuse journal.
Assistant professor of marketing Laura Smarandescu at the Iowa State university said, “People have trouble assessing volumes… They tend to focus more on the vertical than the horizontal measures. That’s why people tend to drink less when they drink from a narrow glass, because they think they’re drinking more.”
The researchers also manipulated several environmental factors to study how it affected the pouring of the alcohol in wine glasses. The environmental factors were like small place setting, large place setting, different meals etc. The glasses were also of difference shapes, sizes and colors.
It was found 11.9 percent more wine was poured in wider glass, 12.2 percent when the person is holding the glass in hand and 9.2 percent more was linked to the matching color of the glass to wine.
A standard drink is considered to be 5 fluid ounces of table wine, 3 to 4 ounces of fortified wine (like port or sherry), 12 fluid ounces of regular beer or 8 to 9 fluid ounces of malt liquor, as per National Institute on Alcohol Abuse and Alcoholism.
