Mountain Valley vs Gerolsteiner
Mountain Valley and Gerolsteiner are each the best-known premium mineral water from their region — but they're built for different purposes. Mountain Valley is a naturally alkaline, moderate-mineral American still spring water; Gerolsteiner is a naturally carbonated, extremely mineral-dense German sparkling water.
Pick Mountain Valley for a still, naturally alkaline, moderate-mineral American water with classic glass presentation. Pick Gerolsteiner if you want the highest natural calcium, magnesium and bicarbonate you can get from a widely available sparkling mineral water.

Which one to pick
Everyday still hydration
Mountain Valley — moderate mineral load, naturally alkaline, classic American glass presentation.
Daily calcium and magnesium intake
Gerolsteiner — roughly 5× the calcium and 12× the magnesium of Mountain Valley per liter.
Sparkling water preference
Gerolsteiner — naturally carbonated; Mountain Valley's sparkling line is a secondary product.
Low-sodium diets
Mountain Valley — 3 mg/L sodium vs Gerolsteiner's 118 mg/L.
Fine dining table water
Both work well — Mountain Valley for still service, Gerolsteiner for high-mineral sparkling.
Frequently asked questions
Which has more minerals, Mountain Valley or Gerolsteiner?
Gerolsteiner, by a wide margin — its TDS of 2,500 mg/L is more than 10 times Mountain Valley's 220 mg/L, and it carries far more calcium, magnesium and bicarbonate.
Is Mountain Valley alkaline like Gerolsteiner?
No — they're on opposite sides of neutral. Mountain Valley is naturally alkaline (pH 7.3–7.8) because it's still water; Gerolsteiner tests mildly acidic (pH 5.9) because dissolved CO₂ from its natural carbonation forms carbonic acid, despite carrying far more alkaline-buffering bicarbonate.
Which is better for athletes?
Gerolsteiner delivers meaningfully more natural electrolytes (calcium, magnesium, sodium, bicarbonate) per liter, making it the stronger pick for mineral replacement. Mountain Valley is a lighter everyday option.
Which tastes better?
Mountain Valley is clean and mild with mineral character in the background. Gerolsteiner is bold and mineral-forward with assertive natural carbonation — a matter of preference more than quality.
