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%).
Guinness is a beer with relatively low carbon dioxide content. Low CO2 beers generally have gas added to them as they're released from the tap (called brewgas-a CO2 and nitrogen mix usually), which gives a thick, creamy head to the beer. The head is very important for flavor and texture of the beer.
