Dark Ales
(including brown ale, stout and porter)
Dark ale includes stout and porter, two ales which are distinguished by their dark color and rich, complex flavor. Dark ales tend to have a slightly smoky flavor and a rich, creamy head. Guinness is probably the most famous stout. Stouts come in a variety of incarnations but most are slightly dry, sweet, and have coffee- or chocolate-like notes which go well with an assortment of foods. Brown ale is a cousin of dark ale, made with more roasted grains and possessing a full, rounded flavor which is not quite as intense as dark ale.
North American commercial examples include Pete’s Wicked Ale, Smuttynose Old Brown Dog Ale, Abita Turbo Dog, and Brooklyn Brown.
