Beer drinkers in British pubs were once adamant that only from their preferred shape of glass did their tipple taste best.

But that is probably because straight glasses are easier for bar staff to collect and stack, rather than because straight-glass lovers have persuaded their fellow-drinkers of the virtue of their view.
The shape of a beer glass does, nevertheless, matter: a group of researchers at the University of Bristol have shown that it can regulate how quickly someone drinks. . . .
