San Pellegrino Sparkling Natural Mineral Water is the first choice of mineral water, from top-end restaurants to funky cafes. The water originates from a layer of rock 400 metres below the surface, where it is mineralized from contact with limestone and volcanic rocks. It emerges from three deep springs at a temperature of about 22 degrees Celcius. The surrounding area, located on the Do range, favours the formation and replenishment of a mineral water basin. The water then seeps to depths of over 700 metres and flows underground to a distant aquifer.
