Wattwiller
Wattwiller is sourced from a spring in the village of Wattwiller, Haut-Rhin department, Alsace, Grand Est, France. The village name derives from Alsatian words for “water” and “village.” The spring lies within the Parc Naturel Régional des Ballons des Vosges, a Natura 2000 protected area. The mineral waters of Wattwiller were probably used in the Roman period; the French government formally authorised commercial exploitation in 1848. Bottling facilities were rebuilt in 1924 by Jean Baptiste Deiber after the First World War. Since 2004, Wattwiller has been owned by the Belgian group Spadel, which also owns Spa and Bru; Wattwiller is Spadel’s French brand. Wattwiller holds natural mineral water status.

Mineral character
Wattwiller is a moderately soft, bicarbonate-dominant water with a notably clean ion profile. Bicarbonate is the highest ion at 135 mg/L; calcium is 35 mg/L; sulphate is 24 mg/L; magnesium is 11 mg/L; sodium is 3 mg/L; chloride is 0 mg/L (below detection). Nitrate is also recorded at zero. Total hardness is 133 mg/L as CaCO₃; alkalinity is 111 mg/L as CaCO₃. TDS is approximately 209 mg/L. The near-zero sodium, zero chloride, and zero nitrate reflect the protected, undeveloped nature of the source area in the Vosges: the only meaningful ions are calcium, magnesium, bicarbonate, and sulphate.
