Harvested from the ancient springs of Rogaška Slatina, Slovenia, ROI is naturally carbonated and filtered through complex geological layers over some 8,000 years. Infused with extraordinarily high levels of magnesium, calcium, and bicarbonate, this water boasts one of the world’s richest mineral profiles.
On the palate, its intense mineral depth is balanced by a bold, crisp texture and a clean, neutral orientation (pH ~6.8), making it taste powerful yet harmonious. ROI isn’t just to be drunk it demands presence.
