A fine English traditional "Yard of Ale" drinking vessel of green glass, measuring exactly 36 inches length (equal to one yard).
A yard of ale or yard glass is a very tall beer glass used for drinking around 2 1/2 imperial pints (1.4 L) of beer, depending upon the diameter.
The glass is approximately 1 yard (90 cm) long, shaped with a bulb at the bottom, and a widening shaft, which constitutes most of the height.
The glass most likely originated in 17th century England, where the glass was known also as a "long glass", a "Cambridge yard (glass)" and an "ell glass". It is associated by legend with stagecoach drivers, though was mainly used for drinking feats and special toasts.
Such a glass was a testament to the glassblower's skill as much as the drinker's. John Evelyn records in his Diary the formal yet festive drinking of a yard of ale toast to James II at Bromley in Kent (now southeast London), 1685.
Yard glasses can be found hanging on the walls of some English pubs, and there are a number of pubs named The Yard of Ale throughout the country.
Drinking a yard glass full of beer as quickly as possible is a traditional pub game; the bulb at the bottom of the glass makes it likely that the contestant will be splashed with a sudden rush of beer towards the end of the feat.
The fastest drinking of a yard of ale in the Guinness Book of Records is 5 seconds.
