What makes a good mineral water?

No two mineral waters are the same. What differentiates them is both their mineral content and their mineral composition. Both of which are determined by the geographical origin, or ‘terroir’ of the mineral water.

 

When shopping, it is wise to compare as the mineral content differs from water to water, sometimes considerably. There are mineral waters with a low mineral content. The label on the bottle will reveal how many and which minerals are present in a mineral water, for example, whether it provides a lot of valuable calcium and magnesium.

The levels and ratio of minerals in water influences its taste: a low-mineral content can result in a sour taste, because the carbonic acid overpowers the presence of other minerals. High-mineral content water tend to have one mineral taste dominate. For example, a lot of sulfate results in a slightly bitter taste. Also, sodium in combination with chloride imparts a salty taste. Gerolsteiner stands apart from all other waters because of its unique mineral content and balance.

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.
