The shape of your glass used when drinking alcoholic beverages could influence your behavior. So says a group of researchers from the University of Bristol‘s Tobacco and Alcohol Research Group.
According to their most recent research presented at a symposium on “Environmental influences on food and alcohol-related behavior” at the annual conference of the British Psychological Society in Liverpool, England people drink beer slower when it is served in straight-sided glasses that when it is served in curved-sided glasses. The study, funded by Alcohol Research UK, also notes that volume markings on glasses also help individuals to drink more slowly.
Dr. Angela Attwood, senior researcher of the study, said in a statement: “The speed at which beer is drunk can have a direct effect on the level of intoxication experienced. This can also increase how much is consumed in a single drinking session. While many people drink alcohol responsibly, it is not difficult to have ‘one too many’ and become intoxicated.”
Part of the study was conducted in a “real world environment” in three different “pubs” or public houses. The research was conducted over a period of two weekends. Data from the drinking establishments that used straight-sided glasses indicated a lower amount of drinking. This matched the investigative team’s previous finding from their laboratory experiments that also demonstrated that subjects drank slower from straight glasses.
Attwood also noted: “Our research suggests that small changes such as glass shape and volume markings can help individuals make more accurate judgments of the volume they are drinking and hopefully drinkers will use this information to drink at a slower pace.”
As is often the case, other members of the scientific community remain skeptical. Dr. Anna Lembke, director of Stanford University’s Addiction Medicine Program, told the press in an e-mail statement: “There’s no doubt that context matters when it comes to alcohol and drug use. But a study showing that social drinkers with marked glasses drank the same amount of alcohol 1.2 minutes slower than drinkers with unmarked glasses is hardly meaningful.”
