In the world of beer, stouts are black, strong and malty, the kind of draught that is poured with a creamy, espresso-hued head. In general, they are smooth, creamy beers that are largely defined by flavors of warm roasty grains; they come in various degrees of sweetness and hoppy bitterness. The most internationally ubiquitous stout, Guinness, is a lighter-bodied version of the style. Some stouts are brewed with chocolate or coffee, a flavor that's worth referencing in a proper food pairing.
