Common questions
- What does FOZ taste like?
- FOZ is a still water, full-bodied, silky and soft, closing on a soft, round finish. It belongs to the Velvet Robe type in our sixteen-part typology, and the house tasting notes run almost textureless softness, faint bicarbonate sweetness and long alkaline finish. Its pH is alkaline, which on the palate reads as silky, slightly bitter.
- Is FOZ good for you?
- FOZ is a regulated bottled water and safe to drink. The published analysis shows a moderately mineral water at 314 mg/L dissolved solids. Sodium sits at 105 mg/L, over the 20 mg/L low-sodium line.
- What minerals are in FOZ?
- FOZ carries calcium 0.5, magnesium 0.01, sodium 105 and potassium 0.4 mg/L over bicarbonate 269, sulfate 7 and chloride 0.4 mg/L. Sodium leads the mineral profile with bicarbonate the main anion, at 314 mg/L total dissolved solids. It also publishes 17 mg/L of silica, the beauty mineral.
- How much sodium is in FOZ?
- FOZ carries 105 mg/L of sodium. That is over the 20 mg/L line a low-sodium claim requires.
- Is FOZ hard or soft water?
- By its calcium and magnesium, FOZ works out to 1 mg/L as calcium carbonate, which counts as soft water. That is soft enough to leave a kettle clean and to drink light.
- Is FOZ alkaline or acidic?
- Yes. FOZ has a published pH of 10.01, on the alkaline side of neutral, where it drinks silky, slightly bitter. That comes from bicarbonate-rich geology rather than any additive.
- Can you use FOZ for baby formula?
- Probably not the first choice. FOZ falls outside the German infant-formula guidance because sodium at 105 is over the 20 mg/L line. Pick a still water that clears all three limits, boil and cool it before mixing, and ask your pediatrician.
- Is FOZ still or sparkling?
- FOZ is a still water, bottled without carbonation.
- Where does FOZ come from?
- FOZ comes from Guarani Aquifer artesian well, São José do Rio Preto, São Paulo state (depth >230 m) in Brazil, a single source.
