San Benedetto was arguably the original favorite of the Republic of Venice, in vogue with aristocratic Venetian families during the Renaissance. The water, tapped at the surface in ancient times, is now drawn from 1,000 feet below ground to ensure that all its original features are unchanged and unadulterated; the water trickles to its source from the glaciers of the Dolomites. Without question, San Benedetto is an elite, low-mineral delicacy that carries a 30 milligram per liter punch of Magnesium.
