A Stout is a strong, dark ale with a slightly bitter or sour flavour.
The dark colour comes from some of the malted barley in it being roasted like coffee beans. There are many ways to use Stout in cooking, from marinades to rich, moist cakes.
Porter is similar to Stout. Both are dark beers, but Stout is sweeter, denser and “hoppier.”
Some brands of Stout other than Guinness are Murphys, Beamish and Crawfords (all brewed in Cork, Ireland.)
