Common questions
- What does b'ui taste like?
- b'ui is a still water, full-bodied, clean and crisp, closing on a soft, round finish, with a silica smoothness. It belongs to the Cathedral type in our sixteen-part typology, and the house tasting notes run mineral-heavy body, saline edge and long bicarbonate finish.
- Is b'ui good for you?
- b'ui is a regulated bottled water and safe to drink. The published analysis shows a rich and mineral water at 920 mg/L dissolved solids, with 28 mg/L of silica (over our glow line). Sodium sits at 175 mg/L, over the 20 mg/L low-sodium line.
- What minerals are in b'ui?
- b'ui carries calcium 120, magnesium 40, sodium 175 and potassium 21 mg/L over bicarbonate 473, sulfate 120 and chloride 184 mg/L. Sodium leads the mineral profile with bicarbonate the main anion, at 920 mg/L total dissolved solids. It also publishes 28 mg/L of silica, the beauty mineral.
- How much sodium is in b'ui?
- b'ui carries 175 mg/L of sodium. That is over the 20 mg/L line a low-sodium claim requires.
- Is b'ui hard or soft water?
- By its calcium and magnesium, b'ui works out to 460 mg/L as calcium carbonate, which counts as very hard water. That is genuinely hard water, chalky on the tongue and quick to scale a kettle.
- Is b'ui alkaline or acidic?
- b'ui is effectively neutral at pH 7.26, neither an alkaline nor an acidic water.
- Can you use b'ui for baby formula?
- Probably not the first choice. b'ui falls outside the German infant-formula guidance because sodium at 175 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 b'ui still or sparkling?
- b'ui is a still water, bottled without carbonation.
- Where does b'ui come from?
- b'ui comes from Manantial San Francisco spring, Tehuacán, Puebla (fed by glacial melt from Pico de Orizaba / Citlaltépetl volcano) in Mexico, a single source.
