Now researchers have finally proved that beauty is in fact in the eye of the beer holder, rather than the beholder.
A pint and a half of beer can produce the effect--and in men it may last 24 hours.
In the study, volunteers were randomly allocated a vodka and lime or a similar tasting non-alcoholic drink.
About half an hour later, both groups were asked to rate the attractiveness of 20 male and 20 female faces on a seven-point scale.
Those who had been drinking alcohol scored the faces about 10 percent higher than the non-drinkers.
When the groups were tested again the next day, the men who had drunk alcohol still gave pictures of women higher ratings than those who had not.
Dr Marcus Munafo, an experimental psychologist who led the study at Bristol University, said: "The findings are important because of the role drink plays in, for example, unsafe sex."
Experts believe that alcohol stimulates the striatum, an area of the brain that plays an important role in attraction.
Previous studies have found that more than two thirds of people--68 per cent--have woken up the morning after the night before regretting handing out their phone number to someone they were not attracted to when sober.
