When did the first pilsner debut?

The first pilsner debuted in 1842 in the Czech city of Plzeň (Pilsen). This style of beer was born out of a desire for a pale lager that was both flavorful and refreshing. The city's brewers faced challenges with the quality of their existing beer, leading them to experiment with innovative brewing techniques, ingredients, and more conducive yeast strains inspired by advancements in lager brewing.
