The treasure of the Volcanic Eifel

Cross-section showing the origin of tap, spring and mineral water

Gerolsteiner Mineral Water is characterized by the geology of the Volcanic Eifel region. In Gerolstein, two geological features meet deep beneath the earth’s surface: calcium and magnesium enriched dolomite bedrock and carbonic acid of volcanic origin. Within the Volcanic Eifel, this unique combination can only be found in Gerolstein – just a few kilometers/miles away, the mineral water has a completely different composition.

The volcanic carbonic acid prompts the release of valuable minerals from the otherwise virtually water-insoluble dolomite. Thanks to this, every liter of Gerolsteiner Sparkling naturally contains 2,500 mg of minerals. Gerolsteiner Naturell (a non-sparkling version of our mineral water) has 885 mg of minerals per liter – more than most other still mineral waters. Thanks to their well-balanced levels of minerals with calcium, magnesium and bicarbonate, Gerolsteiner Mineral Waters have a pleasantly clean and refreshing taste.
