San Pellegrino (also S. Pellegrino) is a brand of mineral water with natural carbonation.The water originates from a layer of rock 400 m (1,300 ft) 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 C (70 F).[1] The surrounding area, located on the Dolomite range, favors the formation and replenishment of a mineral water basin. The water then seeps to depths of over 700 m (2,300 ft) and flows underground to a distant aquifer. serve chilled at 8-10 degree celcius.
