An average 30-year journey through the rock Flowing from the snow and the rain that infiltrate in the high dolomitic mountains (1200-1300 metres above sea level), the water takes average 30 years to travel through the rock before finally arriving at San Pellegrino Terme (at 350 metres ASL). Along the way, it becomes naturally enriched with minerals. The addition of carbon dioxide provides acidity and prolongs the now sparkling water’s sensation of scent and taste, finishing with a slightly bitter note, which has made it famous and unmistakable throughout the world.
