What is alkaline water?
Alkaline water is any drinking water with a pH above 7. It can occur naturally when water flows through carbonate-rich rock, or it can be produced with an ionizer or added mineral blend that raises the pH after bottling.
What pH makes water alkaline?
Above pH 7 is technically alkaline. Most brands marketed as "alkaline water" sit at pH 8 to 10. Under 7 is acidic; exactly 7 is neutral.
Natural alkaline water vs artificially alkaline water
Natural alkaline waters (Icelandic Glacial, Evamor, Fiji) reach their pH through dissolved bicarbonate picked up from rock. Ionized waters (Essentia, Alkaline88, Flow) use electrolysis or added minerals to raise pH post-bottling. Natural waters typically taste smoother; ionized waters typically reach a higher pH.
Best alkaline water brands
- Essentia (pH 9.5) — US market leader, ionized.
- Icelandic Glacial (pH 8.4) — naturally alkaline, low-sodium.
- Evamor (pH 8.8) — natural artesian, Louisiana.
- Flow (pH 8.1) — natural spring, recyclable carton.
- Alkaline88 (pH 8.8) — ionized with added electrolytes.
Highest pH bottled waters
Essentia (pH 9.5), Real Water and TEN (pH 10) push into the highest range. For a full ranking see our highest pH bottled water list.
Alkaline water with minerals
For alkaline water with meaningful natural minerals — not just added electrolytes — look at Evamor, Icelandic Glacial or high-bicarbonate mineral waters like Vichy Catalan and Borjomi.
Is Fiji alkaline?
Yes, mildly. Fiji sits at pH 7.7 — naturally alkaline thanks to the silica and bicarbonate it picks up from Viti Levu's volcanic aquifer.
Is Evian alkaline?
Not really. Evian sits at pH 7.2 — technically just above neutral but not high enough to market as alkaline. See our Evian pH page for details.
Which bottled water is naturally alkaline?
Naturally alkaline options (pH >7.5, no electrolysis) include Icelandic Glacial, Evamor, Fiji, Volcanic (New Zealand), Waiakea and Mountain Valley.
