Unique quality: Very low Total Dissolved Solids (TDS). Some people prefer this as it can be an indication of the water's purity, although this also means there are less beneficial minerals in the water (the lower the TDS, the lower the mineral content). Minerals deliver the health benefits and optimal hydration we look for in a good water (electrolytes are actually minerals), so in our opinion a low TDS is not necessarily indicative of a healthful water.
Our Take On It: Voss is commendable for its commitment to environmental practices. While the glass packaging makes it reusable, Voss would be a more healthful water if it were naturally alkaline. Natural alkaline water cannot be replicated in a lab and is only a result of the natural filtration process as well as the surrounding soil, bedrock, and vegetation. Voss's pH comes in at 6.0 which is actually on the acidic side of the pH scale (7.0 is neutral). That being said, allowing a water to maintain its natural pH is far more healthful than creating an artifically alkline pH through ionization or electrolysis.
