Guinness is widely considered the best stout beer around. This photo or poster can commonly be seen in pubs and restaurants. The Guinness company produces 100 million liters of the fine beverage each year. The firm is located in Dublin, Ireland and has been in production since 1756, when Arthur Guinness founded the brewery. The way the Guinness beer is poured and served is quite different from "normal" beers. When Guinness is poured, it needs to be poured slowly and then allowed to settle in the glass. Guinness beer generally has about 4.1- 4.3% alcoholic content by volume on versions sold in Ireland, but up to 6% alcohol in the United States.
