What is a Porter?

Porter was London's first industrially-produced beer, the drink of river porters, market traders, and anyone who needed a cheap, filling, dark pint in 18th-century England. At its peak, porter was brewed in quantities that would embarrass modern mega-breweries. Then industrial lager arrived and killed it off almost completely. The craft beer revival brought it back — and brewers who rediscovered it found a style of extraordinary flexibility and character.

Porter sits between stout and amber ale in the dark beer spectrum — darker and more roasty than an amber, lighter and sweeter than most stouts. The roasted malt brings chocolate and coffee but without the sharp, bitter edge of roasted unmalted barley that defines a stout. The body is medium: substantial enough to feel like a proper drink, light enough to finish comfortably. ABV 4.5–7.5%, covering everything from a session porter to a hearty winter warmer.

How does it taste?

Chocolate malt leads — proper dark chocolate, not milk chocolate. There's coffee underneath, usually more of a roasted quality than sharp espresso bitterness. Caramel and toffee notes add sweetness that stout typically doesn't have. The body is smooth and rounded, medium carbonation. The finish is satisfying without being heavy — you can have two porters where you'd struggle with two imperial stouts. Serve at 10–13°C for full development.

VS A SIMILAR STYLE

Stout is the obvious neighbour. The traditional distinction: Porters use malted roasted barley (sweeter, more chocolatey); Stouts use unmalted roasted barley (drier, more bitter, more coffee-like). Many modern breweries ignore this entirely. As a rough rule: if a dark beer is sweet and chocolatey, it's probably porter territory. If it's dry and bitter, it's stout territory. But the line blurs constantly — try both and see which end you prefer.
