ROI – Natural Sparkling Mineral Water
Sourced from the historic springs of Rogaška Slatina in Slovenia, ROI is one of the most mineral-rich natural waters in the world. Formed over millennia and naturally carbonated at the source, it carries a composition defined by extraordinary density and precision.
With a Total Dissolved Solids level of 7,481 mg/L and exceptionally high magnesium content, ROI delivers a deeply structured and functional profile. Its fine, persistent effervescence carries a pronounced mineral presence, creating a saline, long finish that lingers with clarity.
Traditionally valued for its restorative properties, ROI is both a gastronomic and functional water—designed to support digestion, replenish minerals, and bring depth to the table.
Why We Love It:
At Rienne, we value water with purpose. ROI stands as a rare expression of mineral intensity—structured, restorative, and deeply rooted in tradition. A water that supports the body while elevating the experience of the table.
