Actually brewed by Pfungstädter for the former brewery "Privatbrauerei Felsenkeller", Beerfelden.
Editor’s note: "You may remember I mentioned a few years ago Felsenkeller in Beerfelden may no longer brew. Joerg Nierbauer recently met the owner who confirmed they stopped brewing several years ago. The brewing equipment was removed in 2007 and exported to the United States. The beers are now brewed in Darmstadt and Pfungstadt. (JN)"
