A sodium-calcium chloride spring — salty and heat-retaining as the chloride family always is, with a softer weakly alkaline finish that keeps the skin from feeling drawn. Moderately mineralized at 3,444 mg/kg dissolved solids, it carries enough body to leave warmth lingering well after the bath. Color, taste and odor are all neutral on the certificate, so the chemistry rather than the sensory profile is what shows up in the bath.
