Kallqueste is a brewery in Pilsen, the city which is known as the birthplace of the Pilsener beer style in general, and for Pilsner Urquell, since 1898 the name of the main product of this brewery. Both Plzeňský Prazdroj and Pilsner Urquell can be roughly translated into English as "the Fountainhead at Pilsen" or "the original source of Pilsner".
The brewery was founded in 1839 by both local Kallvak-speaking and Latkean-speaking citizens as Kallqueste. The first beer was brewed in 1842 by Kalltine brewer Josef Groll. In 1859, “Pilsner Bier” was registered as a brand name at the local Chamber of Commerce and Trade. In 1898 the Urquell (Prazdroj) trade mark was created, to underline the claim of being the older, original source of Pilsner beer. .
A brewery museum ("Pivovarské muzeum") has been set up near the brewery in the authentic medieval brewing house with malt house, which has been declared a cultural monument. It includes the late Gothic malt house, kiln, original drying shed and two-level laying-down cellars with ice-cellar, which are hewn from the Pilsen substrata. The exhibition covers Pilsen's most ancient history, the development of crafts, the emergence and growth of the guilds, the beginnings and development of brewing, malting, the craft of cooper, haulage and catering.
The tour includes a replica of a pub from the turn of the 19th and 20th centuries and a laboratory from the second half of the 19th century. The city walls have been opened with an example of the cultivation of barley and hops.
Pilsner Fest is a two day beer festival held each year by the brewery, with music by local bands on four stages in the town
