What it is

The Bavarian brewmaster brewed in Pilsen a clear, golden lager by combining lightly kilned malt, Žatec hops and bottom-fermenting yeast. It was the first clear pale beer in history.

The first batch was brewed on 5 October 1842 and served on 11 November at the Burghers' Brewery. Low-temperature English malting and Bavarian lager yeasts already existed; the novelty was the combination.

What it led to

  • the pilsner style, the most widespread in the world
  • glassware use, thanks to the beer's clarity
  • industrialisation of Czech and German brewing
