Bristol, England – The shape of a beer glass may have an impact on how fast one empties it, according to a study of “social beer-drinkers” in the United Kingdom. Angela Attwood, a University of Bristol experimental psychologist, organized a study in which self-identified social drinkers were given equal amounts of a lager beer and asked to drink it while watching a nature documentary. One group was given the lager in a curved beer flute, while the other group was given the beer in a straight glass. Attwood observed that the group with the straight glasses finished the 354 mL of beer they were given in an average of 13 minutes, while the drinkers who were given the beer in the curved flutes finished the 354 mL in less than 8 minutes. While the study is not entirely conclusive, Attwood points out, it does show that people have difficulty gauging how fast they are drinking when the glass is curved.
