König Otto-Sprudel brand is owned by Otto König GmbH in Germany.

The König Otto-Bad, which has been family-owned for four generations, is idyllically situated on the edge of the Fichtelgebirge in the northern Upper Palatinate, in the municipality of Wiesau. Since the end of World War II, high-quality mineral water has been extracted there from springs that have been known since the 12th century. This is where a long tradition meets daily innovation.
