Italy's Number 1 Sparkling Water, Ferrarelle gushes from the Sorgenti di Riardo Park, close to Naples, in the South of Italy. Ferrarelle acquires its natural sparkle as carbon dioxide rises through the deepest parts of the extinct volcano Roccamonfina in Campania, near Caserta. The area is currently protected by more than 5000 olive and oak trees. It is also known as the Assno Valley and Bagni, meaning baths.

The natural sparkle and fine balance of precious minerals are the result of the course taken by the water over the millennia. In fact, the rocks from which Ferrarelle springs are many thousands of years old, as are the subterranean strata over which the water flows. Ferrarelle dates back to pre-Roman times.
