Pilsner Urquell is a lager beer brewed by the Pilsner Urquell Brewery in Plzeň, Czech Republic. Pilsner Urquell was the world's first pale lager, and its popularity meant it was much copied, and named pils, pilsner or pilsener. It is hopped with Saaz hops, a noble hop variety which is a key element in its flavour profile, as is the use of soft water. It is available in 330 ml, 355 ml and 500 ml aluminium cans and green or brown bottles.
