Template:Infobox Bottled Water Gerolsteiner Brunnen GmbH & Co. KG (Gerolsteiner) is a leading German mineral water firm with its seat in Gerolstein / Eifel. It is well-known for its Gerolsteiner Sprudel brand, a bottled, naturally carbonated mineral water. Gerolsteiner is also the chief sponsor of a cycling team, Team Gerolsteiner.
On January 1, 1888, the mine manager Wilhelm Castendyck founded the firm Gerolsteiner Sprudel as a GmbH in Gerolstein. In the same year, the first well was drilled. In November 1888, the water became a sort of official water of the city and became popular because of its high amount of natural carbonic acid. In 1889 its star and lion symbol was trademarked. Already in 1895, the water had been exported to Australia. In 1928, the company began to export to the United States.
In 1986, it introduced a brand with a lower amount of carbonic acid to meet changing tastes.
