Brewing city · United Kingdom
London
Where beer first became an industry — a city that invented porter, brewed it in vats the size of buildings, lost almost all of it, and then rebuilt more breweries than it had in the Victorian era.
Porter, and the first industrial beer
Porter emerged in London in the early eighteenth century, and its significance is less about flavour than about scale. It was a dark beer that improved with long maturation, which meant it could be made in enormous quantities, stored, blended and supplied consistently to a very large urban market. That is a description of an industry rather than of a recipe.
The vats were extraordinary. Individual London breweries operated maturation vessels holding tens of thousands of barrels, and the economics of that scale — capital, storage, consistency, distribution — reshaped British brewing for a century. When one of them failed at the Horse Shoe Brewery in 1814 it killed eight people, which is a measure of what was being built.
The name's origin is less certain than usually stated. The association with street porters is old and plausible; the neat story of a publican blending three beers into a single "entire" is a later reconstruction that the record does not really support. BeerHQ carries the association and not the anecdote.
The water made it dark
London's water is moderately hard and notably high in bicarbonate, and alkalinity is the enemy of pale beer: it drives mash pH up, which produces harshness and poor extraction. Dark roasted malts are acidic and pull that pH back down, so a dark beer brewed with London water works where a pale one struggles.
This is the exact mirror of Burton. The two towns had opposite water and consequently opposite beers, and each became famous for the beer its geology permitted. Once the chemistry was understood, London brewers began treating their liquor to make pale ale and Burton brewers had nothing to fix — which is a reasonable summary of why "Burtonisation" is a word and "Londonisation" is not.
The dark family that grew from it is broader than porter alone. Stout began as a description of a stronger porter rather than a separate beer, and London brown ale, mild and the everyday bitters all sit in the same city's history.
Collapse and return
London brewing declined through the twentieth century to something close to extinction. Consolidation absorbed the historic companies, the great porter breweries closed or moved, and by the 1970s a city that had defined industrial brewing had a handful of breweries left. Whitbread, Truman, Courage — names that dominated British beer — went.
The rebuild from the late 2000s was fast and is genuinely remarkable: London now has more breweries operating than at any point since the Victorian era, most of them small, most in railway arches and industrial units, most selling a large share of their output through their own taprooms.
That is a different institution from what was lost. The Victorian industry was porter vats and tied houses; the modern one is small producers selling directly. Both are London brewing, and treating the second as a restoration of the first would misdescribe both.
The houses
Named because of what each one explains about the place, not as a directory. Every entry states whether it is currently operating and when BeerHQ last checked.
A Wandsworth brewery that brewed in London until 2006, when production moved out of the city. The pub company and the brand continue; the London brewery does not, and BeerHQ does not present it as one.
Truman’s
The Brick Lane brewery was among the largest in the world in the nineteenth century and closed in 1989. The name was later revived by a separate company; the original brewery is historical.
Where it is drunk
- The British pub
A licensed house, not a bar: a room licensed to sell drink to the public, with a cellar underneath it and a licensee whose trade depends on what is in it.
- Free house
A pub that is not tied to any brewery and can therefore buy beer from whoever it likes — a claim that appears on signage because for most of British history it was unusual.
- Tied house
A pub owned by a brewery and obliged to sell that brewery’s beer — the arrangement that shaped British beer economics for a century and was largely broken up in 1989.
- Taproom
A bar attached to a brewery, selling that brewery’s beer at the point it was made — the modern craft sector’s answer to not owning any pubs.
Festivals and seasons
What you will hear
- entire
- An eighteenth-century term for beer sold as a single product rather than blended at the pub. Its connection to the origin of porter is often overstated.
- stout
- Originally an adjective meaning strong — a "stout porter" was a strong porter, and the noun came later.
- mild
- Originally meaning fresh and unaged rather than weak or dark. The modern dark mild is a much later development.
How it got here
- 1720Porter emerges
A dark, long-matured beer appears in London and becomes the first beer brewed at genuine industrial scale. Full record.
- 1814The Horse Shoe Brewery flood
A porter vat fails on Tottenham Court Road, killing eight people — an indication of the scale London brewing had reached. Full record.
- 1817Black patent malt patented
Daniel Wheeler's roasting patent lets brewers colour beer with a small proportion of intensely roasted malt, changing how porter and stout are made. Full record.
- 1970–2000Near-extinction
Consolidation reduces London brewing to a handful of companies, and most of the historic names disappear or move production out of the city.
- 2005–2026The rebuild
Small breweries open across the city in railway arches and industrial units, most selling substantially through their own taprooms. London now has more breweries than at any point since the Victorian era.
Why it matters to beer
London water is moderately hard and notably high in bicarbonate. That alkalinity is poorly suited to pale beer, where it produces harshness, but works well with dark roasted malts whose acidity offsets it — a substantial part of why London became a porter city and Burton a pale ale one.
Porter and stout left London almost immediately — Dublin, the Baltic and eventually the world took them up and changed them. London is the origin and the industrial crucible rather than the current centre of either.
What people get wrong
Porter was invented by blending three beers in a pub.
The "three threads" story is a later reconstruction that the documentary record does not really support. Porter appears as a distinct commercially brewed beer, and its significance is the industrial scale it made possible rather than a blending trick.
Stout is a different beer from porter.
"Stout" began as an adjective meaning strong — a stout porter was simply a strong one. The two separated into distinct categories much later, and the modern boundary between them is a matter of convention rather than of a hard technical line.
The modern London brewing revival restored what was lost.
It built something different. The Victorian industry was enormous vats and tied houses; the modern one is small producers in railway arches selling through their own taprooms, and several of the best known have been acquired by large international brewers.
Styles from here
- English porter
The original dark British beer: chocolate and light coffee over a nutty malt base, restrained rather than aggressive.
- Imperial stout
The strongest stout: dense, viscous and intensely roasted, with dark fruit, chocolate and substantial alcohol warmth.
- London brown ale
A low-strength, notably sweet dark brown ale from London, now largely extinct as a commercial style.
Beers brewed here
- Beavertown Gamma Ray
The British-brewed American pale ale that reached supermarket and pub distribution first, and the entry point many British drinkers used into the style.
- Beavertown Neck Oil
A session IPA that solved the hardest problem in the category — keeping hop character at a strength you can drink several of.
- Camden Hells Lager
A London-brewed Helles that made the case for lager as a craft category in Britain.
- Fuller’s 1845
A bottle-conditioned strong ale brewed to mark the brewery’s anniversary, and a clear example of the ground between strong bitter and barley wine.
- Fuller's ESB
The beer that gave "ESB" to the world as a style name, marmalade-rich and considerably stronger than the bitters around it.
- Fuller's London Porter
A widely available modern English porter — chocolate, coffee and soft dark fruit — and a useful direct comparison against Irish dry stout.
- Fuller's London Pride
The most widely available London bitter, malt-forward and marmalade-tinged, and a reliable reference for what best bitter is meant to be.
- Fuller’s Vintage Ale
A bottle-conditioned English strong ale released once a year and dated, so the vintages can be compared directly.
- Young’s Double Chocolate Stout
A London sweet stout with real chocolate added, and the most widely distributed example of the style.

The water
Moderately hard with substantial bicarbonate and low sulphate — suited to porter and brown beer rather than pale ale.
Water is shown here as a property of the place rather than as the reason its beer turned out the way it did. The correlation between a city’s water and its style is real; the causal story is more contingent than it is usually told, and BeerHQ treats it as contested. See London water.
