Beer-glass shape alters your drinking speed: Study. Getty images
Glass shape appears to influence the rate of drinking of alcoholic beverages, researchers have found.
A group of 159 men and women took part in a study conducted by researchers at the University of Bristol where they were filmed drinking either soft drinks or beer.
Participants were asked to abstain from alcohol consumption for 12 hours prior to each test session, and were only enrolled onto the study if they provided a zero breath alcohol reading at the start of the session.
While drinking the participants were asked complete a computerised task identifying perceived midpoint of the two glasses.
The results found that participants were 60% slower to consume an alcoholic beverage from a straight glass compared to a curved glass.
Participants also misjudged the half-way point of a curved glass to a greater degree than that of a straight glass.
There was also no difference in the drinking time for soft drinks. People drinking from both straight and curved glasses finished after around seven minutes.
In conclusion, our data indicate that glass shape influences the rate of consumption of alcoholic beverages, possibly due to differences in the perceptual judgement of the half-way point of the glass across different glass shapes, although further research is required to examine the mechanisms underlying this effect, the researchers said in an article published in the journal PLoS ONE. - TNA
