The Czechs invented the “Pilsener”, no? In Bohemia, no?
They have a nice Beer called “Budvar” which I understand is the great-grand daddy of the US “Budweiser” beer. That’s what I heard.
Pilsner is indeed from Bohemia although the brew master, Josef Groll, was from Bavaria. There is no relationship between the two beers sharing the same Budweiser name other than the name (thank goodness). The micro breweries in the Czech Republic put out some of the best lagers and ales in the world now. Unfortunately, it’s almost impossible to find them outside of the CR or along the borders.
