Founded in 1888, Gerolsteiner Sparkling Mineral Water is the number one water export in Germany. Gerolsteiner’s production follows strict protocols for purity and cleanliness. Originating from springs in Volcanic Eifel, Gerolsteiner flows from ancient, rocky volcanic reservoirs 200 feet beneath the earth’s surface. Minerals and carbonic acid leach into the water as it percolates up through the volcanic rocks, giving Gerolsteiner its exceptionally high amount of calcium, bicarbonate and magnesium. Despite being rich in these essential nutrients, as well as natural carbonation, the water has a refreshing, neutral taste.
