Lauretana
Lauretana is sourced from a spring at Caruzza, at over 1,000 metres altitude in the municipality of Graglia, in the province of Biella, Piedmont, Italy. The water originates from the hydrogeological area of the Monte Rosa glacier. Bottling began in 1965; the brand is named after the Madonna of Loreto, venerated at the nearby Sanctuary of Graglia. Lauretana holds natural mineral water status. The brand is independently owned by the Lauretana company.

Mineral character
Lauretana is the lightest water in the TWD database, and markets itself as the lightest in Europe. Its TDS of 14 mg/L is vanishingly low. Calcium is 1 mg/L, magnesium is 0 mg/L, sodium is 0.88 mg/L, and bicarbonate is 4 mg/L. Total hardness is 2 mg/L as CaCO₃. Sulphate (1 mg/L) and chloride (0 mg/L) are at or near zero. This is as close to distilled water as a natural source gets. For blending, it functions essentially as a diluent: it adds volume without adding minerals.
