Plzeňský Prazdroj — known internationally as Pilsner Urquell — is one of the most historically significant breweries in the world, located in Plzeň (Pilsen), Czech Republic. The brewery was founded in 1842 when the citizens of Plzeň commissioned Bavarian brewer Josef Groll to craft a new beer. The result was a revolutionary golden, clear lager that defined an entirely new style of brewing. In 1898, the Plzeňský Prazdroj trademark was officially registered to protect the unique brand, and the name — meaning 'original source' in both Czech and German — reflects its unrivalled position as the birthplace of the Pilsner style. Today, Plzeňský Prazdroj is the largest brewing group in the Czech Republic, with a portfolio that extends well beyond its flagship Pilsner Urquell. The group encompasses beloved Czech beer brands including Gambrinus, Radegast, Velkopopovický Kozel, and Primus, covering a wide range of styles from classic Czech pale lager to dark and amber beers. The brewmaster lineage at Plzeňský Prazdroj stretches back thirteen generations to Josef Groll himself, underscoring the brewery's deep commitment to tradition and craft. The historic brewery complex in Plzeň remains a major destination for beer enthusiasts worldwide, offering an immersive look into the origins of the Pilsner style. With centuries of brewing heritage and a portfolio spanning several iconic Czech brands, Plzeňský Prazdroj continues to stand as a cornerstone of global beer culture.
