Founded in 1888, Gerolsteiner Sparkling Mineral Water is the number one water export in Germany. In the German style of stringent purity and cleanliness, Gerolsteiner's production follows strict purity protocols. Originating in springs from the area of 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. Gerolsteiner is a great source of essential nutrients that our bodies need daily and its natural carbonation gives Gerolsteiner its refreshing, neutral taste.
