Founded in 1888, Gerolsteiner Mineral Water perseveres as the number one water export in Germany, distributed by more than 40 countries worldwide. In the German style of stringent purity and cleanliness, Gerolsteiner water follows a strict purity certification process from bottling to consumption. Originating in springs from the area of Volcanic Eifel, Gerolsteiner flows from ancient, rocky volcanic reservoirs 200 feet beneath the surface of the earth. This gives Gerolsteiner a high mineral content, including carbonic acid, which helps break down the otherwise non-water-soluble dolomite rocks in the spring and infuses the water with a variety of earthy elements. The acid, it is said, is also responsible for Gerolsteiner’s unique flavor.
