This brand publishes some numbers or ranges in official reports, but not a complete analysis — gaps below are the brand's choice, not ours.
Character
Bands follow the water-sommelier convention (hardness = Ca×2.5 + Mg×4, as CaCO₃; “source protection” is the nitrate measure that world calls virginality) — computed from the values below, never asserted separately.
