Ireland's most famous export, Guinnes Stout - and the people who have brewed it - hold a unique place in the history of beer, business and Ireland itself. Famed beer and beverage writer Bill Yenne talks to everyone from Guinness's master brewer to typical pubgoers about the beer they hold dear. Whatever magic makes it so delicious, it's powerful enough to soothe the souls of beer lovers from Dublin to Boston to Buenos Aires to Lagos, and everywhere in between. But Guinness is more than a delicious beverage, it's also the name of the remarkable family of brewers and entrepreneurs whose story is worthy of legend, and who occupy a prominent place in Irish history. In Guinness, Yenne traces the 250-year tale of the family and its namesake beer. Beginning with Arthur Guinness, the entrepreneur patriarch who first began brewing at St. James's Gate, Dublin, in 1759, the story follows succeeding generations of the Guinness family through the years. Yenne follows not just the fortunes of the family Guinness, but also the development of the brand and the beer - from Arthur's earliest porter to the beer that is enjoyed in 150 countries today.
