Pilsner Urquell Brewery

Plzeňský Prazdroj, a. s. (pronounced [ˈpl̩zɛɲskiː ˈprazdroj a ˈɛs]) (Pilsner Urquell Brewery) is a Czech brewery which opened in 1842 in Plzeň, Bohemia. It was the first brewery to produce a pale lager, branded as Pilsner Urquell, which became so popular and was so much copied that more than two-thirds of the beer produced in the world today is pale lager, sometimes named pils, pilsner and pilsener after Pilsner Urquell. The brewery name, Pilsner Urquell, which can be roughly translated into English as "the original source at Pilsen", was adopted as a trademark in 1898. Pilsner Urquell is the largest producer and exporter of beer in the Czech Republic.

The brewery was part of the SABMiller group of companies from 1999 to 2017. As part of agreements with regulators before Anheuser-Busch InBev was allowed to acquire SABMiller in 2016, Pilsner Urquell was sold to Japan-based Asahi Breweries in 2017.
