Guinness is the world's largest beer brand and is also known as "The Black Beer from Ireland". The brewery was founded in Dublin in 1759. It tastes strong with a slight hint of licorice and has a creamy, white head. Guinness is sold in over 150 countries and a large number of bars are certified by the brewery to pour it according to all the rules of the trade. The aroma develops best when poured at room temperature.
