In a nutshell: A highly hopped and stronger version of their original stout from the Guinness Brewery in Dublin.
The lowdown: Inspired by a recipe dating back to 1801 when Guinness first decided to export their beers around the globe. A forerunner of their Foreign Extra Stout this beer is made with extra hops which gives an enhanced bitterness, There's also a touch of sourness and rich chocolately finish. It has a slightly higher ABV which gives a decided complexity.
One of the most famous beer brands in the world Guinness is still based in Dublin where they've been brewing beer since 1759. In addition to the Original Extra Stout which remains the backbone of their range they also brew several variants aimed at different tastes and markets around the world and, in more recent years, have even brought out a few styles of other ales and lagers.
