Germany’s mineral heavyweight against Italy’s table star. Gerolsteiner is nearly three times as dense (TDS 2500 vs 853) with a huge bicarbonate load (1808 mg/L) that keeps it improbably round for its weight, plus 104 mg/L magnesium, over the taste threshold, so a genuine tonic edge sneaks in. San Pellegrino is drier, not rounder: its mineral character comes from sulfate, and its bead is finer.
Pick Gerolsteiner if you want maximum mineral payload that still drinks smooth, and you like that faint bitter grip. Pick San Pellegrino for a lighter, drier, more food-flexible glass.
