Walk into almost any bar on the planet and you will find a pale, crisp, golden lager. Most of them trace their ancestry to a single brewery in the Bohemian town of Plzeň (Pilsen in German), in what is now the Czech Republic. The beer first brewed there in 1842 became so influential that its hometown’s name turned into a generic word: pilsner.
A town fed up with its beer
In the early nineteenth century, Plzeň’s beer was brewed under an old system in which many townspeople held brewing rights. Quality was, by most accounts, poor and inconsistent. The brewery’s own tradition tells that in 1838 officials judged a batch undrinkable and poured dozens of barrels out in front of the town hall. The episode is part of the brewery’s founding lore, so its details may have been dramatised, but the frustration behind it was real.
The burghers with brewing rights decided to pool their resources and build a modern brewery, the Burghers’ Brewery (Měšťanský pivovar). Instead of the top-fermented ales then common in Bohemia, they wanted to make the bottom-fermented lager fashionable in neighbouring Bavaria.
Josef Groll and the first brew
To run it they hired a young Bavarian brewer, Josef Groll, from Vilshofen. He brewed the first batch on 5 October 1842, and the beer was served to the public in November of that year, around St. Martin’s Day.
Several ingredients came together to make it special:
- Very soft water from local sources, low in minerals, which suited a delicate, pale beer.
- Pale malt from Moravian barley, kilned with indirect heat using methods influenced by English maltsters, instead of the darker, smokier malt common before.
- Saaz (Žatec) hops, a local variety prized for its gentle, spicy aroma.
- Bavarian lager yeast, fermented and matured cold in cellars cut into the sandstone beneath the town.
A romantic legend claims that the yeast was smuggled out of Bavaria by a monk. There is no firm evidence for that, and it belongs in the folklore file.
A golden beer for a glass age
The timing was perfect. Mass-produced glassware was getting cheaper, so more people could see what they were drinking. A clear, golden beer with a white head looked strikingly modern beside murky dark brews. Railways let the beer travel to Vienna, Prague and beyond, and brewers across Europe and then the world began making their own “Pilsner” or “Pils.” In 1898 the original brewery registered the name Pilsner Urquell (“Pilsner from the original source,” Plzeňský Prazdroj in Czech) to set itself apart from its many imitators.
Groll himself left after his contract ended in the mid-1840s and returned to Bavaria. His name remains attached to one of the most influential brews ever made.
Why it matters
The 1842 Plzeň brew set the template for the world’s dominant beer style. Pale lager accounts for the vast majority of global beer volume today, from Czech originals to German Pils to the light mass-market lagers of the Americas and Asia. Many of those descendants taste very different from the full, hoppy Bohemian original, but the line from Josef Groll’s first golden batch to your local lager is surprisingly direct.
