Gerolsteiner Mineral Water: pH, Mineral Content, Ingredients and Benefits

Gerolsteiner is one of the best-known German mineral water brands, especially for people who want a bottled water with a strong mineral profile. Unlike many everyday bottled waters that are mainly valued for purity, light taste, or low mineral content, Gerolsteiner is popular because it contains naturally occurring minerals such as calcium, magnesium, bicarbonate, sodium, potassium, and other dissolved solids.

For shoppers comparing premium bottled waters, Gerolsteiner often appears in searches for high mineral content water, German mineral water, mineral-rich water, and sparkling mineral water. Its bold mineral profile makes it different from lighter still waters such as Fiji or Evian and from many standard spring water brands.

This guide explains what Gerolsteiner is, where it comes from, what minerals it contains, its pH level, possible benefits, and how it compares with San Pellegrino and Fiji Water.

Gerolsteiner is a natural mineral water brand from Germany. It is best known for its sparkling mineral water, although the brand also offers still and medium-carbonation varieties in some markets. The water is naturally mineralized as it moves through underground rock layers, collecting minerals from the surrounding geology.

The main reason Gerolsteiner stands out is its high level of dissolved minerals. Gerolsteiner states that its Sparkling mineral water contains around 2,500 mg/L of total minerals, while its still Naturell version contains around 800–885 mg/L depending on the source or market reference.

For people who prefer a clean, light-tasting bottled water, Gerolsteiner may taste stronger than expected. For people who enjoy mineral-forward sparkling water, it can feel crisp, structured, and refreshing.

Gerolsteiner comes from the Volcanic Eifel region of Germany, an area known for its volcanic rock formations and mineral-rich geology. The brand is associated with Gerolstein in the Eifel mountains, where the water is naturally enriched as it passes through layers of volcanic rock.

This geological setting is important because mineral water is shaped by its source. The rock layers, underground path, and natural filtration process all influence the final mineral composition. That is why Gerolsteiner tastes different from French alpine waters like Evian, Italian mineral waters like San Pellegrino, or artesian waters like Fiji.

Gerolsteiner mineral water does not have “ingredients” in the same way a flavored beverage does. Its contents are mainly water plus naturally occurring minerals.

Commonly listed mineral components include:

Gerolsteiner’s mineral profile is naturally occurring, but exact numbers may vary slightly by product, bottle label, country, and testing source.

Gerolsteiner is considered a high-mineral bottled water. FineWaters lists Gerolsteiner with a TDS of about 2,527 mg/L, calcium around 347 mg/L, magnesium around 108 mg/L, sodium around 119 mg/L, potassium around 10.8 mg/L, bicarbonate around 1,817 mg/L, sulfate around 36.3 mg/L, and chloride around 39.7 mg/L.

Gerolsteiner Mineral Content Table

Gerolsteiner’s own mineral education pages note that its Sparkling mineral water contains 348 mg/L of calcium, 108 mg/L of magnesium, and 1,816 mg/L of bicarbonate.

Gerolsteiner Sparkling Mineral Water contains about 108 mg/L of magnesium. Gerolsteiner notes that a mineral water is considered a source of magnesium if it contains at least 50 mg/L, meaning Gerolsteiner is well above that level.

Magnesium contributes to Gerolsteiner’s reputation as a mineral-rich water. It also affects taste, giving the water a fuller mineral character than many lower-TDS bottled waters.

Gerolsteiner Sparkling Mineral Water contains about 348 mg/L of calcium according to Gerolsteiner’s own calcium information page.

That makes it significantly higher in calcium than many common still bottled waters. Calcium also contributes to water hardness. This is one reason Gerolsteiner has a more noticeable mineral taste and a heavier mouthfeel than light spring waters.

Gerolsteiner’s pH is often listed around 5.9 to 6.3 for its sparkling mineral water, depending on testing source and carbonation. FineWaters lists Gerolsteiner at pH 5.9, while a laboratory report for Gerolsteiner Sparkling recorded a pH value of 6.3.

This does not mean Gerolsteiner is “bad” water. Sparkling waters often test lower on the pH scale because dissolved carbon dioxide forms carbonic acid. At the same time, Gerolsteiner contains high levels of bicarbonate and minerals.

Yes. Gerolsteiner is a high-mineral bottled water. A TDS level above 1,500 mg/L is generally considered high mineral content by FineWaters’ classification, and Gerolsteiner is listed around 2,527 mg/L.

That places Gerolsteiner above many familiar bottled waters, including Fiji, Evian, and San Pellegrino in total dissolved solids. It is especially high in calcium, magnesium, and bicarbonate.

Gerolsteiner’s main appeal is its naturally high mineral content. Possible benefits include:

• It provides naturally occurring calcium.
• It provides naturally occurring magnesium.
• It contains a large amount of bicarbonate.
• It has a bold, mineral-rich taste.
• It may be a good option for people who enjoy sparkling mineral water with substance.
• It can pair well with meals because of its strong carbonation and mineral structure.

Gerolsteiner states that its Sparkling water contains high amounts of calcium, magnesium, and bicarbonate.

However, bottled water should not be treated as a substitute for a balanced diet or medical advice. People with kidney disease, sodium restrictions, or mineral-related health concerns should ask a qualified healthcare professional before relying on high-mineral water daily.

For most healthy adults, Gerolsteiner can be part of normal hydration. The main thing to understand is that it is not a low-mineral water. It contains much more calcium, magnesium, bicarbonate, and sodium than many light bottled waters.

Gerolsteiner may not be the best choice for everyone. People who need low-sodium water, low-mineral water, or water for infant formula preparation should compare labels carefully and follow medical or pediatric guidance.

Also, because Gerolsteiner Sparkling is carbonated, its pH may test lower than still water. That is normal for many sparkling waters, but people with sensitive teeth or reflux concerns may prefer to moderate intake or choose still water.

Gerolsteiner and San Pellegrino are both premium sparkling mineral waters, but they have different mineral profiles.

FineWaters lists San Pellegrino with TDS of 1,109 mg/L, calcium of 208 mg/L, magnesium of 56 mg/L, and sodium of 44 mg/L. San Pellegrino says its water comes from the San Pellegrino Terme area in Val Brembana in the Italian Alps.

Gerolsteiner is the stronger choice if you want very high mineral content. San Pellegrino may be better if you want a classic sparkling mineral water with a smoother restaurant-style profile.

Gerolsteiner and Fiji Water are very different.

Fiji Water’s FAQ lists its pH as 7.7, and retailer label data commonly lists Fiji with silica, calcium, magnesium, bicarbonate, and TDS around 222 mg/L.

Choose Gerolsteiner if you want strong minerality and bubbles. Choose Fiji if you want a smooth, still bottled water with a lighter mineral profile.
