Flashback Friday: Curvy vs. straight – which glass ups your drinking rate?

By Seriously Science | October 4, 2013 12:00 pm

Does it really matter which glass you choose for your beer? In this study, scientists from England tested the effect of glass shape on alcohol consumption. Turns out that a curved glass made people drink 60% faster than a straight glass, but only for beer (not soft drinks). This effect could be due to the fact that people were worse at judging the halfway point of the curved glass compared to the straight one. Guinness, anyone?

Glass shape influences consumption rate for alcoholic beverages.

“High levels of alcohol consumption and increases in heavy episodic drinking (binge drinking) are a growing public concern, due to their association with increased risk of personal and societal harm. Alcohol consumption has been shown to be sensitive to factors such as price and availability. The aim of this study was to explore the influence of glass shape on the rate of consumption of alcoholic and non-alcoholic beverages.
METHODS:
This was an experimental design with beverage (lager, soft drink), glass (straight, curved) and quantity (6 fl oz, 12 fl oz) as between-subjects factors. Social male and female alcohol consumers (n = 159) attended two experimental sessions, and were randomised to drink either lager or a soft drink from either a curved or straight-sided glass, and complete a computerised task identifying perceived midpoint of the two glasses (order counterbalanced). Ethical approval was granted by the Faculty of Science Research Ethics Committee at the University of Bristol. The primary outcome measures were total drinking time of an alcoholic or non-alcoholic beverage, and perceptual judgement of the half-way point of a straight and curved glass.
RESULTS:
Participants were 60% slower to consume an alcoholic beverage from a straight glass compared to a curved glass. This effect was only observed for a full glass and not a half-full glass, and was not observed for a non-alcoholic beverage. Participants also misjudged the half-way point of a curved glass to a greater degree than that of a straight glass, and there was a trend towards a positive association between the degree of error and total drinking time.
CONCLUSIONS:
Glass shape appears to influence the rate of drinking of alcoholic beverages. This may represent a modifiable target for public health interventions.”
