Gerolsteiner Magnesium: 108 mg/L, One of the Highest of Any Bottled Water
Gerolsteiner is known for very high mineral content. The brand says its Sparkling and Medium waters contain 2,479 mg/L total mineral content, which places them in the high-mineral category.
Why Gerolsteiner is different
Gerolsteiner comes from the volcanic Vulkaneifel region in Germany. The water rises through layers of dolomite rock, picking up calcium, magnesium and bicarbonate along the way. The result is one of the most mineral-dense bottled waters sold internationally.

Why is the pH lower if it has so many minerals?
Gerolsteiner Sparkling is carbonated. Carbonation lowers pH because dissolved carbon dioxide forms carbonic acid. That is why a sparkling mineral water can be mineral-rich and still taste crisp or slightly acidic on the tongue.
Best use
Gerolsteiner is a good choice for people who want a bold sparkling mineral water, especially with meals. It is not the best choice if you prefer a soft, neutral, low-mineral bottled water for all-day sipping.
