"Pilsner" is a classification largely stripped of meaning by the mass-market American breweries. But in Europe, It's far more than just light colored lager.
The term desribes one of the oldest styles of lagered beer, which originated in the Czech city of Pilsen. Expect is a light gold colored, noticeably hoppy brew with a thick, foamy head.
Several excellent Czech pilsners are available in the USA. Pilsner Urquell being the best known and mst common.
Czechvar, from the town of Ceske Budejovice, (Budweis in German), was fromerly known as Budvar, "The Real Budweiser,"until Anheuser Busch sued their ass, having co-opted the Budweiser name over a century ago. Needless to say, Czechvar is superior to the American usurper in every conceivable way.
