From the brewery:

Made with the purest, softest spring water from protected sources in the beautiful Black Forest mountain region of South West Germany, Rothaus Pils is a uniquely pure and flavoursome German pilsner beer.

The best aromatic hops from Tettnang and Hallertau as well as local malt made from summer barley and the purest spring water from the Black Forest give Rothaus Pils its uniquely fresh and tangy taste.
