Draught beer
Draught beer, also spelt draft, is beer served from a cask or keg rather than from a bottle or can. Draught beer served from a pressurised keg is also known as keg beer.
Until Joseph Bramah patented the beer engine in 1785, beer was served directly from the barrel and carried to the customer. The Old English dragan ("carry; pull") developed into a series of related words including drag, draw, and draught. By the time Bramah's beer pumps became popular, the use of the term draught to refer to the acts of serving or drinking beer was well established and transferred easily to beer served via the hand pumps. In time, the word came to be restricted to only such beer. The usual spelling is now "draught" in the United Kingdom, Ireland, Australia, and New Zealand and more commonly "draft" in North America, although it can be spelt either way. Regardless of spelling, the word is pronounced /drɑːft/ or /dræft/ depending on the region the speaker is from.
Canned draught is beer served from a pressurised container featuring a widget. Smooth flow (also known as cream flow, nitrokeg, or smooth) is the name brewers give to draught beers pressurised with a partial nitrogen gas blend.
In 1691, an article in the London Gazette mentioned John Lofting, who held a patent for a fire engine: "The said patentee has also projected a very useful engine for starting of beer, and other liquors which will draw from 20 to 30 barrels an hour, which are completely fixed with brass joints and screws at reasonable rates".
In the early 20th century, draught beer started to be served from pressurised containers. Artificial carbonation was introduced in the United Kingdom in 1936, with Watney's experimental pasteurised beer Red Barrel. Though this method of serving beer did not take hold in the UK until the late 1950s, it did become the favoured method in the rest of Europe, where it is known by such terms as en pression. The carbonation method of serving beer subsequently spread to the rest of the world; by the early 1970s the term "draught beer" almost exclusively referred to beer served under pressure as opposed to the traditional cask or barrel beer.
In Britain, the Campaign for Real Ale (CAMRA) was founded in 1971 to protect traditional—unpressurised—beer and brewing methods. The group devised the term real ale to differentiate between beer served from the cask and beer served under pressure. The term real ale has since been expanded to include bottle-conditioned beer.
Keg beer is often filtered and/or pasteurised, both of which are processes that render the yeast inactive.
In brewing parlance, a keg is different from a cask. A cask has a tap hole near the edge of the top, and a spile hole on the side used for conditioning the unfiltered and unpasteurised beer. A keg has a single opening in the centre of the top to which a flow pipe is attached. Kegs are artificially pressurised after fermentation with carbon dioxide or a mixture of carbon dioxide and nitrogen gas or especially in Czech Republic solely compressed air.
