Beer through time

The history of beer

Beer is about thirteen thousand years old and almost everything that decides how it tastes was invented in the last three hundred. This is how it got here — and which of the famous stories about it hold up.

Beer is roughly thirteen thousand years old and almost all of its technology is less than three hundred: fermented cereal residues predate agriculture, while the saccharometer, pale lager, refrigeration and pure yeast culture all arrive within a single century.10,000 BCE1,000 BCE0 CE100015001800190019502000Fermented cereal11,000 BCEMesopotamia3,000 BCEHymn to Ninkasi1,800 BCEHops spread1200Bavarian ordinance1516Porter1720Saccharometer1784Black patent malt1817Pale lager1842Refrigeration1873Pure yeast1883Crown cork1892Prohibition1920The can1935CAMRA1971American craft1980Haze2016
Drawn on a logarithmic scale of time before the present, because a linear one would compress everything before 1700 into a single mark at the left-hand edge. Distances are therefore not to scale, deliberately: the shape this shows is that beer is very old and nearly all of its technology is very recent.

Nine eras

Chronology on its own explains nothing. Each of these is a stretch of time with an argument in it — something that can be said about the whole span and not about any single event inside it.

  1. c. 11000 BCE – 500 BCEAncient beer — Fermented cereal drinks are older than agriculture, older than writing and older than the word beer — and almost everything stated confidently about them is more uncertain than it sounds.
  2. c. 500 – 1500Medieval brewing — Brewing moved from something almost every household did into a trade with premises, capital and guilds — and the people who were doing it changed completely as a result.
  3. c. 1700 – 1900Industrial brewing — Beer became the first mass-produced consumer product, and the technologies that made that possible — measurement, power, pale malt, rail — also decided which beers survived.
  4. c. 1500 – 1900Lager and the conquest of cold — Lager was a beer you could only make in cold places at cold times of year, until it was not — and the technology that removed the constraint is why most of the world now drinks it.
  5. c. 1850 – 1910Brewing becomes a science — In sixty years brewing acquired a theory of what fermentation is, a method for controlling it, and a laboratory culture — and stopped being a trade with unexplained failures.
  6. c. 1890 – 1960Packaging and reach — Beer stopped being something you went out to drink and became something you bought and took home — a change driven by three unglamorous inventions and one heat treatment.
  7. c. 1830 – 1950Temperance, war and prohibition — For a century the biggest force acting on beer was not brewing at all: it was tax, war and organised opposition to drinking, and they changed what was in the glass more than any brewer did.
  8. c. 1950 – 2000Consolidation and revival — Choice narrowed almost everywhere for thirty years, and then was rebuilt from below — by a consumer campaign in Britain and by homebrewers in the United States, for quite different reasons.
  9. From 2000Modern beer — The technical frontier moved from process to ingredient and perception — hop chemistry, yeast selection, haze and the removal of alcohol — while the industry that produced it consolidated again.

The technologies that changed the beer

Not a list of inventions but of adoptions, because adoption is what actually changes what people drink — and it is usually driven by money rather than by merit. Each one says what brewing was like before it and what it made possible.

All 14 technologies

The stories that do not hold up

Beer history carries an unusual density of confidently repeated claims that do not survive contact with the sources — largely because much of the popular account was written as marketing and then recycled by writers with no reason to doubt it. Each of these carries a verdict, and the verdicts are not all “false”.

People

Carried for one reason: the sentence attached to each of these names is wrong, incomplete, or attached to the wrong achievement, and correcting it teaches something about beer.

The full chronology

63 dated events, with how well each is attested. 11 of them carry the popular version alongside the documented one, because raising a myth without correcting it would be worse than not mentioning it — the data model refuses one without the other.

Before 1800

  1. -11000 The oldest evidence of a fermented cereal drink

    Well attested Residues in stone mortars at Raqefet Cave in Israel, roughly thirteen thousand years old, consistent with malting and fermenting wild wheat or barley.

  2. -1800 The Hymn to Ninkasi is written down

    Documented A Sumerian hymn to the goddess of beer, dating to roughly 1800 BCE, describing stages that appear to correspond to brewing in poetic language.

  3. 1100–1500 Hopped beer spreads across northern Europe

    Well attested Over roughly four centuries hopped beer displaced herb-bittered ale across northern Europe, driven as much by tax and trade as by taste.

  4. 1350–1600 Women are displaced from commercial brewing

    Well attested United Kingdom. As hopped beer made larger batches and distance trade viable, brewing moved from a household activity into a capitalised trade — and out of women’s hands.

  5. 1516 The Bavarian purity ordinance

    Documented Germany. A Bavarian ordinance restricting beer to barley, hops and water, fixing prices and reserving wheat and rye for bread.

  6. 1553 Bavaria restricts brewing to the cooler months

    Documented Germany. Regulation confining brewing to the period between autumn and spring, which produced both Märzen and the practice of lagering.

  7. 1700–1750 Porter emerges in London

    Contested United Kingdom. A dark, aged London beer becomes the first mass-market industrial product, though how and when it appeared is disputed.

  8. 1762 Combrune argues for the brewing thermometer

    Documented United Kingdom. Michael Combrune publishes on the use of the thermometer in brewing, arguing for measurement in a trade that ran on judgement.

  9. 1780–1840 Pale ale is exported to India

    Contested United Kingdom. London and later Burton brewers built an export trade in pale, well-hopped stock ale to India — the trade that gave IPA its name.

  10. 1784 Richardson publishes on the saccharometer

    Documented United Kingdom. John Richardson applies the hydrometer to wort and publishes the tables that turn a reading into a decision — showing brewers that brown malt was poor value.

  11. 1784–1800 Steam power reaches the brewery

    Documented United Kingdom. London porter breweries install steam engines for milling, pumping and hoisting, removing the ceiling that muscle power had placed on brewery scale.

The nineteenth century

  1. 1800–1850 Indirect-fired kilning makes pale malt practical

    Well attested Drying malt with hot air rather than over an open fire allowed pale, smoke-free malt to be produced at scale.

  2. 1814 The London beer flood

    Documented United Kingdom. A porter vat at the Horse Shoe Brewery failed, releasing hundreds of thousands of litres into the surrounding streets and killing several people.

  3. 1817 Daniel Wheeler patents black malt

    Documented United Kingdom. A drum-roasting patent that let brewers produce dark beer from a mostly pale grist, changing how porter was made.

  4. 1820–1900 Baltic brewers ferment export porter as a lager

    Well attested Poland. Brewers around the Baltic reproduced strong British export stout using bottom fermentation and cold maturation, producing a smoother beer of the same strength.

  5. 1820–1880 Irish brewers adopt unmalted roasted barley

    Well attested Ireland. Malt taxation made unmalted roasted grain the cheaper route to colour and roast, and the resulting sharpness became the defining flavour of Irish stout.

  6. 1830–1920 Temperance movements reshape drinking law

    Documented Organised opposition to drinking, strongest in Britain and the United States, produces the licensing regimes, opening hours and duty structures that still shape how beer is sold.

  7. 1830–1860 The Burton union system comes into use

    Well attested United Kingdom. A linked array of oak casks that continuously separated yeast from fermenting beer, and a large part of the character of Burton pale ale.

  8. 1839 The railway reaches Burton upon Trent

    Documented United Kingdom. Rail connection allowed an inland town to supply national and export markets, and Burton grew into one of the largest brewing centres in the world.

  9. 1842 The first pale bottom-fermented beer is brewed in Plzeň

    Documented Czechia. A Bavarian brewer, exceptionally soft local water, pale kilned Moravian malt and Saaz hops produced a beer that reshaped world brewing within a generation.

  10. 1860–1900 Vienna lager survives in Mexico

    Well attested Mexico. Central European brewers emigrating to Mexico carried the Vienna amber lager tradition with them, and it persisted there after largely disappearing in Austria.

  11. 1873 Mechanical refrigeration reaches the brewery

    Documented Germany. Carl von Linde’s ammonia refrigeration, first installed in a brewery in the early 1870s, freed lager production from cold cellars and natural ice.

  12. 1876 Bass registers the red triangle

    Documented United Kingdom. Generally cited as the first trade mark entered under the UK Trade Marks Registration Act, and still one of the most recognisable marks in brewing.

  13. 1876 Pasteur establishes that fermentation is microbial

    Documented France. Work through the 1860s and 1870s showed that fermentation is caused by living organisms and that beer spoilage is microbial, making deliberate control of both possible.

  14. 1883 Hansen isolates a pure yeast culture at Carlsberg

    Documented Denmark. Emil Christian Hansen isolated a single yeast strain at the Carlsberg Laboratory, making reproducible lager fermentation possible — and the brewery published the method rather than patenting it.

  15. 1892 The crown cap is patented

    Documented United States. William Painter’s crown cork gave bottled beer a cheap, reliable, gas-tight seal, and is why beer bottles need no cork.

  16. 1894 Munich answers Bohemian pale lager with Helles

    Well attested Germany. Munich brewers, losing ground to pale Bohemian beer, produced a pale lager of their own — maltier and less bitter than the beer it responded to.

1900 to 1970

  1. 1900–2000 The sparkler divides British cask service

    Traditional account United Kingdom. Northern British practice adopted the sparkler and the tight creamy head it produces; southern practice largely did not, and the divide has persisted.

  2. 1903 Machine-made glass makes bottled beer cheap

    Documented United States. Automatic bottle production makes glass cheap and uniform, and — with the crown cork already available — turns packaged beer into a mass-market product.

  3. 1908 A brewery statistician publishes the t-distribution

    Documented Ireland. William Sealy Gosset developed small-sample statistics while working on quality control at a Dublin brewery, publishing as "Student" because his employer treated the work as commercially sensitive.

  4. 1914–1950 British beer strength collapses through two wars

    Documented United Kingdom. Wartime restriction and gravity-based taxation drove British beer strengths down sharply, and they never returned to nineteenth-century levels.

  5. 1920–1933 American Prohibition

    Documented United States. Thirteen years of national prohibition destroyed most of American brewing and its regional diversity; the survivors consolidated around light adjunct lager.

  6. 1926–2020 The Hüll programme breeds disease-resistant German hops

    Documented Germany. A long-running German breeding programme produced successors to wilt-susceptible traditional varieties, and later a generation of aromatic modern ones.

  7. 1933 The American three-tier system is created

    Documented United States. After repeal, American states separate producers, wholesalers and retailers by law — an arrangement designed to prevent brewery-owned saloons that shaped the industry for ninety years.

  8. 1935 Beer is first sold in cans

    Documented United States. Flat-topped steel cans requiring a separate opener went on sale in Richmond, Virginia; aluminium and the integrated tab came much later.

  9. 1950–1990 Lambic declines, then is deliberately preserved

    Well attested Belgium. Spontaneous fermentation nearly disappeared under competition from sweeter commercial products before a small number of producers deliberately preserved the traditional method.

  10. 1955–1975 British brewing consolidates into national groups

    Well attested United Kingdom. A wave of mergers produced a small number of national brewers who replaced cask beer with keg products across large tied pub estates.

  11. 1956 Westmalle names the tripel

    Well attested Belgium. The abbey’s strong pale ale, refined into its modern form in the 1950s, gave an entire Belgian style category its name and its reference example.

  12. 1959 Nitrogen dispense is developed for stout

    Well attested Ireland. A nitrogen and carbon dioxide blend was developed to give keg stout the soft texture and dense head of well-kept cask beer.

  13. 1960–2015 Berliner Weisse declines and is reinvented

    Well attested Germany. Berlin’s sour wheat beer nearly disappeared, and the modern revival is largely kettle-soured rather than made by the mixed fermentation of the historical beer.

  14. 1965 Fritz Maytag buys Anchor Brewing

    Documented United States. A failing San Francisco brewery was bought and rebuilt around traditional methods at the low point of American brewing diversity.

  15. 1966 Pierre Celis revives witbier

    Documented Belgium. Belgian witbier had ceased to be brewed. A former milkman who had worked at the last wit brewery in Hoegaarden restarted production from memory and historical practice.

1970 to 2000

  1. 1971 CAMRA is founded

    Documented United Kingdom. Four drinkers founded what became the Campaign for Real Ale, defining "real ale" and organising consumer pressure against keg-only national brewers.

  2. 1972 Cascade is released

    Documented United States. The USDA breeding programme released a hop whose grapefruit-and-floral character was unlike anything in European brewing.

  3. 1978 Homebrewing is legalised in the United States

    Documented United States. Federal legislation removed the prohibition on brewing beer at home for personal use, an omission left over from the repeal of Prohibition.

  4. 1980 Sierra Nevada Pale Ale goes into production

    Documented United States. A Chico brewery built a pale ale around Cascade, and in doing so defined what American hops taste like to the rest of the world.

  5. 1980–2020 Southern Hemisphere hop breeding produces a distinct character

    Well attested New Zealand. New Zealand and Australian programmes produced varieties whose thiol-driven tropical and white-wine character differs markedly from American hops.

  6. 1986 The Kölsch Convention restricts the name to Cologne

    Documented Germany. Cologne brewers agreed to restrict the name Kölsch to beer brewed in and around the city, later supported by protected geographical status.

  7. 1987 Super Dry reorders the Japanese market

    Documented Japan. A highly-attenuated "dry" lager launched in Japan and triggered a market realignment that changed the ranking of the country’s brewers.

  8. 1987 The European Court rules on the German purity requirements

    Documented Germany. The Court held that Germany could not use its purity rules to bar beer lawfully produced in other member states from being sold as beer.

  9. 1989 The Beer Orders break the brewery-pub tie

    Documented United Kingdom. Legislation limited how many tied public houses a large brewer could own, restructuring the British market and separating pub ownership from brewing.

  10. 1992 Commercial bourbon-barrel ageing begins

    Well attested United States. A Chicago brewery aged imperial stout in used bourbon barrels, starting a practice now found worldwide.

  11. 1993–2015 Grodziskie dies out and is reconstructed

    Documented Poland. Poland’s smoked wheat beer ceased production entirely in the 1990s and was reconstructed two decades later from records and surviving knowledge.

  12. 1994–2004 The double IPA emerges

    Well attested United States. West Coast brewers pushed IPA to higher strength and far higher hop rates while keeping it dry, establishing a category defined by intensity without sweetness.

  13. 1997 The Authentic Trappist Product mark is established

    Documented Belgium. The International Trappist Association created a certification mark for goods made within monastery walls under monastic control, with proceeds to the community or charity.

  14. 1998 Cask Marque begins accrediting cellar quality

    Documented United Kingdom. An independent scheme began inspecting and accrediting the condition of cask beer as actually served, rather than as brewed.

Since 2000

  1. 2000–2020 Thiol chemistry explains modern hop aroma

    Well attested Research identified polyfunctional thiols, perceptible in parts per trillion, as responsible for much of the tropical and blackcurrant character of modern hops — and showed that yeast releases many of them from bound precursors.

  2. 2002 Small brewers’ relief is introduced in Britain

    Documented United Kingdom. Reduced duty for low-volume producers, widely credited with the subsequent multiplication in the number of British breweries.

  3. 2004–2016 The hazy IPA emerges in New England

    Well attested United States. Vermont brewers produced a soft, low-bitterness, aroma-driven IPA that inverted the West Coast template and became the dominant modern style.

  4. 2006–2020 Gluten-free and gluten-reduced beer diverge as categories

    Well attested Beer brewed from naturally gluten-free grain and barley beer treated with enzymes came to be regulated differently, because test methods are unreliable on hydrolysed gluten.

  5. 2010–2024 Alcohol-free brewing becomes credible

    Well attested Vacuum distillation with aroma recovery, membrane separation and maltose-negative yeasts turned alcohol-free beer from an apology into a category people choose.

  6. 2011–2020 Large brewers begin acquiring craft breweries

    Documented United States. A sustained wave of acquisitions moved well-known craft breweries into multinational ownership, sharpening the argument about what "craft" means.

  7. 2011 The wild parent of lager yeast is identified

    Documented Saccharomyces eubayanus, the cold-tolerant parent of lager yeast, was found in Patagonian forests — nearly five centuries after the hybrid began brewing beer.
