Voss has long been a symbol of premium bottled water, known as much for its sleek cylindrical bottle as for its supposed purity. Hailing from a protected artesian aquifer in southern Norway, the water is naturally filtered and is bottled without extensive processing. While this sounds impressive, the term 'chemicals' can spark concern. However, in the context of drinking water, 'chemicals' primarily refers to naturally occurring minerals. The composition of Voss water, whether still or sparkling, is what truly defines its unique taste and low mineral profile. Examining its chemical makeup reveals not a long list of additives, but rather a simple, naturally occurring mix of minerals.
The Mineral Profile of Voss Still Water
Voss still water is defined by its remarkably low mineral content and low total dissolved solids (TDS). The water from the artesian aquifer is protected for centuries by impermeable layers of rock and sand, which results in very few minerals being dissolved into it. This minimal TDS is a major factor behind its signature clean, crisp taste. The still water's chemical profile is quite straightforward, comprising a very low concentration of the following key minerals:
- Calcium: A very low 3–5 mg/L.
- Magnesium: Less than 1 mg/L.
- Sodium: A minimal 4–6 mg/L.
- Chloride: A low 12 mg/L.
- Bicarbonates: Less than 20 mg/L.
The low mineral count also affects the still water's pH, which typically hovers around 5.5–6.0, placing it on the slightly acidic side. The low sodium and minimal mineral content make Voss Still a good option for those on a low-sodium diet or who prefer a neutral-tasting water.
The Ingredients of Voss Sparkling Water
Voss sparkling water, by contrast, has a significantly different chemical profile from its still counterpart. The carbonation process not only adds fizz but also alters the mineral balance, increasing some compounds to achieve its distinct flavor profile and bubbly texture. The sparkling variety has a higher total dissolved solids count, approximately 290–300 mg/L, and a lower pH of around 4.8–5.2. Its chemical composition includes:
- Carbon Dioxide: Added for carbonation.
- Sodium Bicarbonate: A key ingredient that increases sodium content and adds to the distinct taste.
- Sodium: A much higher 90–100 mg/L due to the added bicarbonate.
- Bicarbonates: Around 230–250 mg/L, a dramatic increase over the still water.
- Calcium, Magnesium, Chloride: These remain at low levels, similar to the still water.
The increase in bicarbonates and sodium provides a more complex taste profile than the simple, clean flavor of the still water. For individuals monitoring their sodium intake, it's important to note the difference in sodium levels between the two Voss varieties.
A Side-by-Side Comparison of Voss Water
The table below provides a clear comparison of the key chemical components found in Voss Still and Sparkling water from their primary Norwegian source. Values are presented in milligrams per liter (mg/L) based on official reports.
| Mineral / Parameter | VOSS Still (mg/L) | VOSS Sparkling (mg/L) |
|---|---|---|
| Calcium | 3–5 | 3–5 |
| Magnesium | <1 | <1 |
| Sodium | 4–6 | 90–100 |
| Chloride | 12 | 12 |
| Bicarbonate | <20 | 230–250 |
| Total Dissolved Solids (TDS) | 44 | 290–300 |
| pH | 5.5–6.0 | 4.8–5.2 |
Beyond the Minerals: Addressing Chemical Concerns
While minerals are the primary chemical components of Voss water, consumer concern about other contaminants is valid. Voss conducts extensive testing on its water sources and finished products to ensure compliance with all relevant quality and safety standards, including U.S. FDA and California regulations. In these reports, many harmful inorganic, volatile organic, and synthetic organic chemicals are listed as 'ND' (Not Detected).
Another concern is the potential for chemicals to leach from plastic bottles, particularly when exposed to heat. Voss water is available in both glass and plastic (PET) bottles. Choosing a glass bottle or ensuring proper storage of the plastic bottle can help mitigate any potential risks associated with plastic leaching. Voss's brand identity, tied to its pristine Norwegian source, suggests a strong emphasis on maintaining a clean and pure product from source to consumer.
What Determines Voss's Signature Taste?
The unique taste of Voss is directly linked to its mineral composition, or lack thereof, especially in the still water. The exceptionally low TDS count results in a water that is almost flavor-neutral, which many people find particularly refreshing and pure. This contrasts with mineral-rich waters that have a more distinct, sometimes earthy, flavor from higher levels of dissolved minerals. The pristine, protected source in Norway contributes to this consistency of taste, as it is shielded from the atmospheric and geological influences that could alter the water's chemical makeup.
The Artesian Source and Bottling Process
The entire process, from extraction to bottling, is designed to preserve the water's natural state. The water is sourced from an artesian aquifer, which is under sufficient pressure to push the water naturally towards the surface. This means the water requires minimal intervention before bottling. The still water is bottled at the source without undergoing filtration, which preserves its unprocessed nature. Regular analytical tests are performed at the source to verify the constancy of the mineral composition, ensuring that what goes into the bottle is as consistent as what comes out of the ground.

Conclusion: The Final Verdict on Voss's Ingredients
In conclusion, the 'chemicals' in Voss water are predominantly naturally occurring minerals. The low TDS of the still water makes it distinctively pure and clean-tasting, while the addition of carbon dioxide and sodium bicarbonate creates the fizz and higher mineral content of the sparkling version. Both varieties are sourced from a protected Norwegian aquifer, with extensive testing conducted to ensure safety and quality. When choosing between still and sparkling, understanding the different chemical compositions—particularly the sodium content and pH—can help you make an informed decision based on taste preference and dietary needs. Ultimately, the simple and low-mineral nature of Voss still water is what sets it apart in the premium bottled water market.
