On 1 January 1888 the mine manager, Wilhelm Castendyck, founded the firm, Gerolsteiner Sprudel, as a Gesellschaft mit beschränkter Haftung (GmbH) in Gerolstein. Its first well was drilled in the same year. By November, the water from the well had become a sort of 'official' water of the city. It was popular because of its high amount of natural carbonic acid. In 1889, its star-and-lion symbol was trademarked. By 1895, the water was being exported to Australia. More information...
