In 1821, his son Arthur Guinness II established the recipe for a Guinness Extra Superior Porter, the precursor to the Guinness stout known worldwide today. Although Guinness is brewed in 49 countries and sold in 150, Guinness itself owns five breweries worldwide, including St. James Gate in Dublin.One is in Malaysia, and the rest are in Africa, specifically in Nigeria, Ghana and Cameroon.owever, the Guinness variant popular in Ireland, the UK and the U.S. is not the popular one in Africa, where they prefer the Guinness Extra Foreign Stout, a variant with a much higher alcohol content (7.5%) than the draft (around 4.0%).
The brewery also produces Guinness Original, a 4.3% abv version of the Draught, without the nitrogen; Kaliber, a low alcohol pale lager; Guinness Bitter, a 4.4% bitter sold in a can with a widget; and the 7.5% Guinness Foreign Extra Stout.he brewery also made all of its own power using its own power plant. There is an attached exhibition on the 250-year-old history of Guinness, called the Guinness Storehouse.
