This article is about the measurement of beer known as the yard. For other definitions, see Yard (disambiguation).

A yard of beer (or Yard Glass or Yard o' Ale) is a term used to describe a very tall glass used for drinking beer. The glass itself is appoximately 3 feet (1 yard) tall, and can hold approximately 3 pints (1.7 litres) of liquid. The glass is shaped with a bulb at the bottom for balance, and a widening shaft which comprises most of the height.

Common practice is not to casually drink from the glass as if it were a normal beer, but to drink the beer as rapidly as possible, whilst being cheered on by the already drunken ensemble of a gathering. Indeed, the tradition is most often associated with drunken and disorderly tomfoolery in party-like environments.

The ritual of the yard-glass sculling competition (who can empty the contents of the glass the fastest) is predominant in, but not restricted to, Australian "bogan" culture. However the glass itself most probably originated from the United States, where it is reported that the tavern owners would provide beverages to the drivers of carrages by using the long necked glass. This would allow the driver to reach down and grasp the yard glass while remaining seated in his horse-drawn coach.

The yard glass has had a significant affect on Australian drinking and popular culture. For example, in 1954 at Oxford ex-prime minister Bob Hawke got a Guinness Book World Record for draining a yard glass in 12 seconds!
