Source comparison
Borjomi rises from volcanic springs in the Caucasus, used medicinally for over a millennium. Gerolsteiner draws from the Vulkaneifel — German volcanic terrain renowned for its mineral-dense aquifers.
Borjomi vs Gerolsteiner
Two of the most mineralized naturally carbonated waters on earth, from opposite ends of Europe. Borjomi from Georgia vs Gerolsteiner from Germany.
Mineral content comparison
| Mineral | Borjomi | Gerolsteiner |
|---|---|---|
| TDS (mg/L) | ~5,500 | ~2,500 |
| Bicarbonate | ~3,800 | ~1,816 |
| Calcium | ~80 | ~348 |
| Magnesium | ~45 | ~108 |
| Sodium | ~1,200 | ~118 |
| pH | ~7.5 | ~5.9 |
Taste profile
Borjomi is unmistakably savory and alkaline, with a distinctive mineral signature drinkers either love or find polarizing. Gerolsteiner is more balanced — mineral-rich but cleaner and more universally approachable.
Best use cases
- Borjomi: digestive aid, post-meal sipping, traditional remedy
- Gerolsteiner: daily electrolyte support, with food, post-exercise
Frequently asked questions
Which has more minerals?
Borjomi has higher total TDS and more bicarbonate; Gerolsteiner has dramatically more calcium and magnesium.
Which is more alkaline?
Borjomi at ~pH 7.5 reads more alkaline than Gerolsteiner at ~pH 5.9 — the latter is naturally carbonated, which lowers pH.
Which is better for digestion?
Borjomi has been used traditionally for digestion thanks to its very high bicarbonate. Gerolsteiner also helps but in a milder, daily-driver way.
