One of the sadly neglected problems in modern science is the question of how best to keep beer cool once it has been poured into a glass. Now one scientist has come up with a novel solution by developing a mathematical model that determines the optimal shape of a beer glass that keeps beer cool.
The problem is well known to generations of beer drinkers the world over. As soon as beer is poured into a glass, it starts to warm up. So an important goal is to minimize the heat entering the beer so that it stays colder for longer.
Typically, beer drinkers have solved this problem with foam sleeves, insulating mugs and by adding handles to reduce contact with the drinker’s hand. But Claudio Pellegrini at the Federal University of São João del-Rei in Brazil has taken a different approach by redesigning the glass itself, without adding any ...
