Imbibing from a glass with a curved edge encourages a person to drink more quickly, according to new research.
In the conduct of the study, 150 men and women were brought to 3 taverns over a period of two weekends to find out if the shape of the drinking vessels affects how much alcohol intake they consumed.
Researchers were able to conclude that based on their experiments conducted, those who took their drink of choice from a curved glass found it tougher to determine how quickly their drink was going down.
Those subjects who drank from a straight glass were able to track the volume of their intake more effectively.
Bar owners testified that those individuals who drank from a straight sided glass, ordered 24 % less as compared to those who used the curved glasses.
Researches also noticed that when a glass has calibration markings on its side, punters slowed down the speed at which they imbibed significantly.
When there is a visible measurement marking, drinkers were prone to take an average of 10.3 minutes to consume a drink. But if no visible calibration were seen on the glass, people polished off their beverage in 9.1 minutes flat.
One of the researchers from Bristol University, David Troy, who carried out the study, is adamantly concluding that when a curved glass is used, it is a lot more difficult to tell how much we are drinking. However, he understands the impracticality for businesses to ban them altogether.
Hence, to solve this problem, he suggests that all curved glasses should carry volume measurement calibration to “help people slow down a bit”.
