Pilsner (also pilsener or simply pils) is a type of pale lager. It takes its name from the Czech city of Pilsen, where it was first produced in 1842 by Bavarian brewer Josef Groll from local ingredients.The world’s first blond lager, the original Pilsner Urquell,is still produced there today

Origin

The city of Pilsen began brewing in 1295, but until the mid-1840s, most Bohemian beers were top-fermented. The taste and standards of quality often varied widely, and in 1838, consumers dumped whole barrels to show their dissatisfaction.The officials of Pilsen founded a city-owned brewery in 1839, called Měšťanský pivovar Plzeň (German: Bürger-Brauerei, English: Citizens' Brewery – now Pilsner Urquell), which was to brew beer in the pioneering Bavarian style.^[4] Brewers had begun aging beer made with cool fermentingyeasts in caves (lager, i.e., German: gelagert [stored]), which improved the beer's clarity and shelf-life. Part of this research benefited from the knowledge already expounded on in a book (printed in German in 1794, in Czech in 1799), written by Czech brewer František Ondřej Poupě (Ger: Franz Andreas Paupie) (1753–1805) from Brno.

The Pilsen brewery recruited the Bavarian brewer Josef Groll (1813–1887) who, using new techniques and paler malts, presented his first batch of pale lager on 5 October 1842. The combination of brighter malt prepared by English technology, Pilsen's remarkably soft water, local Saaz noble hops from nearby Žatec and Bavarian-style lagering produced a clear, golden beer that was regarded as a sensation. Groll returned to Vilshofen three years later in 1845, and there later inherited his father's brewery.

Emergence of efficient glass manufacturing in Europe, around the same time, lowered glass prices. This allowed the general population to purchase glass drinking vessels for the first time. These former luxury items showcased the visually pleasing golden clarity of the beer, further influencing the Pilsner's rapid dissemination.

In 1853, the beer was available in 35 pubs in Prague. In 1856, it came to Vienna and in 1862 to Paris. Improving transport and communications also meant that this new beer was soon available throughout Europe, and the Pilsner style of brewing was soon widely imitated. In 1859, “Pilsner Bier” was registered as a brand name at the Chamber of Commerce and Trade in Pilsen. In 1898, the Pilsner Urquell trade mark was created to put emphasis on being the original brewery (Urquell meaning original well, the English equivalent would probably be prototype pilsener beer).

Some beers are labeled Urtyp Pilsener (UP) meaning that they are brewed according to the original process, although many breweries use this accolade for their top beer.
