In an Irish Car Bomb, which stout beer is used?

The stout beer used in an Irish Car Bomb is Guinness. This choice is quintessential for the drink, as Guinness is one of the most iconic Irish stouts, known for its distinct dark color, creamy head, and rich flavor profile. The combination of Guinness with the elements of the Irish Car Bomb—typically whiskey and Irish cream liqueur—creates a unique flavor and visual presentation that highlights the stout's characteristics.

While Murphy's and Beamish are also Irish stouts that could technically be used, they do not hold the same legacy or recognition in the context of the Irish Car Bomb. Smithwick’s, on the other hand, is not a stout but rather an Irish red ale, making it an unsuitable choice for this particular cocktail.
