Owing to its unique balance of calcium, magnesium and bicarbonate, Gerolsteiner has a pleasant harmonious taste without any dominant individual mineral notes. Also, thanks to its acid-neutralizing effect, bicarbonate ensures a well-balanced taste. Gerolsteiner Sparkling contains at least 1,800 mg of bicarbonate per liter.
