ROI Roitschocrene — The Legend from Slovenia since 1647

There is no comparable water on this planet. That is not marketing. That is geology.

ROI comes from Rogaška Slatina in eastern Slovenia, a location at the intersection of three major geological structures: the Alps, the Dinaric Alps, and the Pannonian Basin. This unique tectonic configuration creates the conditions for what ROI is: the most magnesium-rich natural mineral water in the world.

The History

The spring itself is over 8,000 years old. Written records date to around 1300, when the spring water was already known for its health-promoting properties. In 1572, Leonhard Thurneysser presented the first chemical analysis in his work Pison.

The mythology runs even deeper: according to legend, the winged horse Pegasus struck the earth in Rogaška at Apollo's command, opening the spring. Apollo declared: "Here springs the source of health and the true power of the gods."

In 1665, Count Petar Zrinski drank the water while hunting — his miraculous recovery led him to introduce ROI to the entire European royal family. In 1680, Dr. Paul de Sorbait, court physician to Emperor Leopold I, examined the water and described it in his Praxis Medicae, calling it "The God Potion." In 1687, Joannes Benedict Gründel wrote the first and only monograph on a single water in Europe — naturally, it was about ROI.

By 1774, ROI was so sought-after that counterfeits appeared on the market. Empress Maria Theresa decreed that every bottle from Rogaška must bear the year of bottling and an annually changing symbol. Prices were published in Viennese newspapers. That is royal quality control.

In 1893, ROI received a quality medal at the World Exhibition in Chicago — named the third best water in the world, alongside Selters and Vichy.

"As with wine, it is not only the qualities that one can perceive, but also the history." Michael Mascha, Founder of the Fine Water Society

The Source

The springs of Rogaška Slatina sit at the heart of Slovenia's most tectonically diverse region. The oldest rock layer dates to approximately 285 million years ago. At a depth of 300 meters, this unique geological system enriches the water with magnesium, calcium, sulfates, and bicarbonates. Radiocarbon dating estimates the age of the artesian spring water at around 8,000 years. It rises to the surface without pumps — driven by the carbon dioxide it contains.

In 1721, Emperor Charles VI granted the Vienna Pharmacists' Association the concession to use the spring. In 1803, Ferdinand Attems purchased the land around the springs and founded the spa town — today known as the Rogaška Spa Resort.

The Health

ROI works differently depending on how you drink it: fast and warm to accelerate intestinal activity, slow and cool to increase mineral absorption. Since magnesium regulates the entire nervous and muscular system, the world's most magnesium-rich mineral water is an ideal complement to a demanding lifestyle — in moderation.

"Think about it — way more electrolytes than Gatorade. But straight from Mother Nature." Martin Riese, World's leading water sommelier

The Taste

ROI carries one of the highest TDS values of any bottled water on the planet. Its enormous mineral content delivers a distinctive, voluminous, and rich taste — the elements in harmonious balance, easily absorbed by the body in soluble form.

"This is strong water." Evan Chang, Buzzfeed

"ROI is like a cognac for me. I always call it the Big Boy." Martin Riese

The Design

With the renaming from Roitschocrene to ROI in 2011 came a new design philosophy. Since then, the brand has received prestigious awards from the Fine Water Society and other institutions year after year — for both design and taste.

Exclusivity

ROI is available exclusively through FINE LIQUIDS in Germany and Europe. Production is strictly limited to protect the source.

ROI is a member of the Fine Water Society.
