Wine lovers know that terroir—the soil, climate, and geography where grapes grow—defines a wine's character. The same concept applies to water, and it's the reason Evian tastes different from Fiji, and both taste different from your tap.
The Mineral Fingerprint
As water moves through rock and soil, it dissolves minerals along the way. The specific minerals—and their ratios—depend entirely on the geology of the source. Limestone aquifers produce calcium-rich water. Volcanic regions add silica and trace minerals. Glacial sources tend toward lower mineralization.
This mineral composition isn't just about health—it fundamentally shapes how water tastes and feels on your palate.
Why Minerals Matter
- Calcium (Ca)
- Adds a slight minerality and "weight" to water. Essential for bones and cardiovascular function.
- Magnesium (Mg)
- Creates a subtle bitterness at higher levels. Critical for muscle and nerve function.
- Bicarbonate (HCO₃)
- Provides "softness" and a slightly creamy mouthfeel. Acts as a pH buffer.
- Silica (SiO₂)
- Adds smoothness and a velvety texture. Found in volcanic spring waters.
- TDS (Total Dissolved Solids)
- The sum of all minerals. Low TDS = light, clean taste. High TDS = mineral-forward, complex.
Famous Water Terroirs
French Alps (Evian): Filtered through glacial sand for 15+ years. Low mineralization (309 mg/L TDS), high calcium, neutral pH. Clean, refreshing character.
Fiji Islands: Artesian source filtered through volcanic rock. Moderate mineralization, high silica content. Distinctive smooth, soft mouthfeel.
Italian Dolomites (San Pellegrino): Naturally carbonated from limestone aquifer. High mineralization (915 mg/L TDS), significant calcium and sulfate. Bold, mineral-forward taste.
Icelandic Springs: Filtered through volcanic lava rock. Very low mineralization (~60 mg/L TDS). Exceptionally pure, nearly neutral taste.
The Pure Canvas Approach
Here's where it gets interesting: what if instead of accepting whatever minerals your tap water happens to contain, you started with a pure canvas and added minerals intentionally?
This is the philosophy behind CUIVEN's terroir collection. Our RO+DI purification removes virtually all dissolved solids, creating ultra-pure water. Then, we add back carefully calibrated mineral blends that replicate the exact profiles of world-famous water sources.
The result: you can experience the character of Alpine springs, volcanic islands, or limestone aquifers—all from your kitchen.
Beyond Taste: Functional Hydration
Different mineral profiles aren't just about preference—they serve different purposes. Higher magnesium content may support recovery after exercise. Calcium-rich water contributes to daily mineral intake. Silica is associated with skin and hair health.
With programmable mineral profiles, your water can adapt to your needs throughout the day.
The CUIVEN Terroir Collection includes profiles inspired by the French Alps, Fiji, Italian Dolomites, Icelandic Springs, New Zealand, and custom mineral balances.
