Sibling gypsum giants from the Vosges, and the two chalkiest glasses in the catalog. Hépar is the extreme: 549 mg/L calcium, 119 mg/L magnesium — comfortably over the 100 mg/L taste threshold, so the bitterness is real — and 1530 mg/L of drying sulfate. Contrex is the same idea turned down a notch (Ca 468, Mg 74.5, SO₄ 1187): still liquid limestone, but its magnesium sits below the line most palates notice.
Pick Hépar if you’re here for the full spa-cure experience, bitter edge included. Pick Contrex for the same dry, chalky, mineral-dense profile with less of the grip.
