ROI Natural Mineral Water

A 3,000-Year Journey, Bottled for the Few Who Truly Appreciate It

Drawn from the sacred underground spring of Rogaška Slatina, ROI is one of the rarest and most mineral-rich waters on Earth — naturally carbonated, exceptionally pure, and shaped over millennia by geological forces no lab could replicate. Revered for its unmatched magnesium content and legendary origin, ROI is not just hydration — it is a mineral elixir, born of nature and revered by the world’s elite.

Bottled at the source, ROI carries a bold mineral profile with naturally occurring bubbles, offering a distinctive, almost saline complexity on the palate. It’s the preferred pour of sommeliers and wellness aficionados alike, prized for its digestive support, revitalizing properties, and ability to stand beautifully beside elevated cuisine.

Why We Love It:

According to legend, this spring was revealed when Pegasus struck the earth with his hooves, opening what would become a sacred site of healing. Today, ROI rises naturally to the surface—effervescent, untouched, and rich in dissolved minerals. With a Total Dissolved Solids (TDS) level of 7,481 mg/L, this water is not only complex and bold in character—it is profoundly restorative.

Aged through 8,000 years of natural filtration, ROI is bottled at the source with no artificial carbonation, no additives, and no compromise. Its smooth texture, mineral-forward profile, and award-winning taste make it a preferred pour for Michelin chefs, elite athletes, and water sommeliers worldwide.
