Stout is a dark, heavy-bodied top-fermented ale whose colour and roasted character come from roasted barley or roasted malt.
Thick and creamy on the palate, finishing dry with a medium bitterness; the aroma is intensely roasted, coffee-like and dark.
Pour it slowly as the bulk liquid or a float — it is carbonated and foams readily, so a fast pour over other liquids will overflow. Used unsweetened for its dark colour, roasted aroma and heavy body rather than as a small accent.
Another dark, roasted beer that preserves the deep colour and coffee-like aroma and keeps a heavy body — a porter serves well, and strength can differ within the style without changing identity; a pale or unroasted beer cannot stand in.
Porter
Stout evolved from porter and the two overlap substantially — stout historically denoted the strongest ('stoutest') porters, and dry Irish stout is distinguished by roasted unmalted barley whereas porter typically relies on malted brown or chocolate malt. Modern usage of the terms overlaps, and the distinction is often a matter of brewer labelling rather than a firm rule.
Brewed from roasted malt or roasted barley together with hops, water and yeast, stout spans a wide strength range and several substyles: dry Irish stout uses roasted unmalted barley for a dry, coffee-like roast and deep colour, while oatmeal stout adds a proportion of oats — normally up to about 30% — for a smoother, fuller body.
Keep sealed and cool; once opened it goes flat quickly, so use promptly.
Stout began as a stronger version of London porter in the 18th century, where 'stout porter' denoted the strongest porters; the style became strongly associated with Ireland through Guinness, which was brewing porter at its St. James's Gate Brewery by 1776.
