Guinness

Guinness is a dry stout that originated in Arthur Guinness's St. James's Gate Brewery in Dublin, Ireland. The beer is based upon the porter style that originated in London in the early 1700s. It is one of the most successful beer brands in the world, being exported worldwide. The distinctive feature in the flavour is the roasted barley which remains unfermented. For many years a portion of the beer was aged to give a sharp lactic flavour, but Guinness has refused to confirm if this still occurs. The thick creamy head is the result of a nitrogen mix being added during the serving process. It is extremely popular with the Irish and is the best-selling alcoholic drink of all time in Ireland, where Guinness & Co. makes almost €2billion annually.

Now available around the world, the brand is heavily associated with Ireland.
