A test report from July 2026 gives Wolfach 58.5 mg/L (3.3 °dH), which is soft water. The figure covers the town centre (Kernstadt) only; outlying districts with their own supply may differ and are not included here. With soft water, limescale is rarely an issue at home, and detergent can be dosed for soft water.
German law (WRMG) uses 3 bands: soft < 8.4 °dH, medium 8.4–14 °dH, hard > 14 °dH.
