Guinness Original/Extra Stout

Guinness stout is available in a number of variants and strengths, which include:

*Guinness Draught, sold in kegs, widget cans, and bottles: 4.1 to 4.3% alcohol by volume (ABV); the Extra Cold is served through a super cooler at 3.5°C (38.3°F).
*Guinness Original/Extra Stout: ranges from 4.2 to 6.0% ABV
*Guinness Foreign Extra Stout: 7.5% ABV. The basis is an unfermented but hopped Guinness wort extract shipped from Dublin, which is added to local ingredients and brewed locally. In Nigeria a proportion of sorghum is used. Foreign Extra Stout is blended with a small amount of intentionally soured beer.
*Guinness Special Export Stout, Commissioned by John Martin of Belgium in 1912. The first variety of Guinness to be pasteurised, in 1930.
*Guinness Bitter, an English-style bitter beer: 4.4% ABV.
*Guinness Extra Smooth, a smoother stout: 5.5% ABV.
*Malta Guinness, a non-alcoholic sweet drink.
*Guinness Mid-Strength, a low-alcohol stout test-marketed in Limerick, Ireland in March 2006 and Dublin from May 2007: 2.8% ABV.
*Kaliber, a premium alcohol-free lager. It is brewed as a full strength lager; then at the end of the brewing process, the alcohol is removed: 0.05% ABV.
*Guinness Red, brewed in exactly the same way as Guinness except that the barley is only lightly roasted so that it produces a lighter, slightly fruitier red ale; test-marketed in Britain in February 2007: 4.1% ABV.
*250 Anniversary Stout; 5% ABV.

In October 2005, Guinness announced the Brewhouse Series, a limited-edition collection of draught stouts available for roughly six months each. There were three beers in the series.

*Brew 39 was sold in Dublin from late 2005 until early 2006. It had the same alcohol content (ABV) as Guinness Draught, used the same gas mix and settled in the same way, but had a slightly different taste. Many found it to be lighter in taste, somewhat closer to Beamish stout than standard Irish Guinness.
*Toucan Brew was introduced in May 2006. It was named after the cartoon toucan used in many Guinness advertisements. This beer had a crisper taste with a slightly sweet aftertaste due to its triple-hopped brewing process.
*North Star was introduced in October 2006 and sold until into late 2007. Three million pints of North Star were sold in the latter half of 2007.
*Despite an announcement in June 2007 that the fourth Brewhouse stout would be launched in October that year, no new beer appeared and, at the end of 2007, the Brewhouse series appeared to have been quietly cancelled.

*In March 2006, Guinness introduced the "surger" in Britain. The surger is a plate-like electrical device meant for the home. It sends ultrasonic waves through a Guinness-filled pint glass to recreate the beer's "surge and settle" effect. The device works in conjunction with special cans of surger-ready Guinness. Guinness tried out a primitive version of this system in 1977 in New York. The idea was abandoned until 2003, when it began testing the surger in Japanese bars, most of which are too small to accommodate traditional keg-and-tap systems. Since then, the surger has been introduced to bars all across the quadrant.

*Withdrawn Guinness variants include Guinness's Brite Lager, Guinness's Brite Ale, Guinness Light, Guinness XXX Extra Strong Stout, Guinness Cream Stout, Guinness Gold, Guinness Pilsner, Guinness Breó (a slightly citrusy wheat beer), Guinness Shandy, and Guinness Special Light.

:''Breó (meaning 'glow' in ancient Irish) was a wheat beer; it cost around 5 million Irish punts to develop.''

*For a short time in the late 1990s, Guinness produced the "St James's Gate" range of craft-style beers, available in a small number of Dublin pubs. The beers were: Pilsner Gold, Wicked Red Ale, Wildcat Wheat Beer and Dark Angel Lager.

*A brewing byproduct of Guinness, Guinness Yeast Extract (GYE), was produced until the 1950s.

*In March 2010, Guinness began test marketing Guinness Black Lager, a new black lager, in Northern Ireland and Malaysia.
