Glass Shape Influences How Fast We Drink Alcohol

How fast a person drinks alcohol may be influenced by the shape of the glass, according to a study from the U.K.'s University of Bristol.

Researchers enlisted 160 social drinkers ages 18 to 40. The volunteers, who had no history of alcoholism, were asked to attend two sessions.

At one session, they were asked to drink either lager or a non-alcoholic soft drink from either a straight-sided glass or a curved beer glass. While there was no difference in drinking speed from either type of glass when the volunteers drank the non-alcoholic beverage, they drank twice as slowly when they drank alcohol from the straight-sided glass.

The researchers theorize that it may be more be more difficult to accurately assess the halfway point of shaped glasses. As a result, drinkers are less able to gauge how much they have consumed.

To test their theory, the volunteers attended another session in which they looked at pictures of glasses containing liquid and were asked to judge whether the glass was more or less than half full. Those who were the poorest judges were the ones who tended to drink faster when the glass was curved.

In another study, researchers found that markings on curved glasses helped drinkers judge how much they had consumed. When participants drank from curved glasses that had markings showing quarter, half, and three-quarter marks, those who drank from the marked glasses had slower drinking times.

The speed at which an alcoholic beverage is drunk influences the number of drinks consumed in a drinking session and also the level of intoxication a person experiences. Slowing drinking, say the researchers, is likely to have a positive impact on both individuals and the population as a whole.

"While many people drink alcohol responsibly, it is not difficult to have 'one too many' and become intoxicated," said researcher Angela Attwood.

"People often talk of 'pacing themselves' when drinking alcohol as a means of controlling levels of drunkenness, and I think the important point to take from our research is that the ability to pace effectively may be compromised when drinking from certain types of glasses," Attwood said.
