brewed in the USA by immigrant German brewers worked with ingredients native to America to create a unique Pilsner. died out after Prohibition but was resurrected as a homebrewed style  

The classic American Pilsner was brewed both pre-Prohibition and post-Prohibition with some differences. OGs of 1.050-1.060 would have been appropriate for pre-Prohibition beers while gravities dropped to 1.044-1.048 after Prohibition. Corresponding IBUs dropped from a pre-Prohibition level of 30-40 to 25-30 after Prohibition.

20-30% flaked maize to dilute the excessive protein levels.
Native American hops (Clusters), traditional continental noble hops, or modern noble crosses (Ultra, Liberty, Crystal) are appropriate.
Modern American hops such as Cascade are inappropriate.
Water with a high mineral content can lead to an inappropriate coarseness in flavor and harshness in aftertaste.
