The story
Porter was the first beer brewed on a truly industrial scale. It emerged in London in the early 1700s and was named after the street and river porters who drank it in huge quantities. A popular story credits a brewer named Ralph Harwood with inventing it in 1722 as a single beer that mimicked a pub blend called “three threads” — but that account appeared decades later and historians treat it as legend. Porter most likely evolved gradually from London’s brown beers.
What’s certain is that porter made fortunes. Breweries like Whitbread, Truman and Barclay Perkins built gigantic vats to age it. The strongest porters were called “stout porters,” which eventually became simply stout. By the 20th century porter had faded in England, surviving longer in Ireland, before craft brewers revived it from the 1970s onward.
What it tastes like
Modern English porter is moderately dark and malt-driven. Expect chocolate, toffee, caramel and dark bread, with a gentle roast that’s softer and less acrid than a dry stout. Earthy English hops provide balance, and English yeast adds subtle fruitiness. The body is medium, the finish ranges from slightly sweet to fairly dry, and the color is deep brown, often with ruby highlights when held up to light.
How it’s made
Historic porter was brewed with brown malt, which was kilned over wood fires and tasted smoky. As more efficient pale malt and, after 1817, the newly patented black malt became available, brewers switched to pale malt for fermentable sugar with a little black malt for color. Today’s recipes typically combine pale malt with crystal, brown and chocolate malts. English hops and an English ale yeast complete the recipe.
Fun fact
In October 1814, a huge vat of porter burst at the Horse Shoe Brewery in London, sending a wave of hundreds of thousands of liters of beer through the surrounding streets. The London Beer Flood demolished buildings and killed eight people — a tragic reminder of just how enormous porter production had become.
