Stout

A very dark, heavy, top-fermented beer made from pale malt, roasted unmalted barley, and often caramel malt. Stout was first introduced by Guinness as an extra stout version of their porter. The new stout was darker, hoppier and richer than porter, which it gradually overtook in popularity. A distinction is drawn between sweet stout and dry stout although both are highly hopped, sweet stout is less bitter than dry stout. See also Russian stout.
