Tourism is Ireland's second largest industry and whether you taking in Dublin, a city that is electrifying and ever expanding or the emerald hills of the countryside that are made for movie magic. At one time when Irish people drank more whisky, Arthur Guinness started brewing a beer that was quite different. It contained roasted barley, giving it an uncharacteristically dark colour. Today its one of the worlds favourite beer, and its not really a beer at all its a Stout!
