Tesco British Natural Mineral Water

Tesco British Natural Mineral Water is a moderately soft water with a clean, balanced profile. Bicarbonate is the highest ion at 166 mg/L, with calcium at 40 mg/L and magnesium at 14 mg/L giving a total hardness of 158 mg/L as CaCO₃. Sulphate (10 mg/L), chloride (13 mg/L), and sodium (6 mg/L) are all low. The profile is near-identical to the discontinued Tesco Ashbeck, with only chloride reduced from 17 to 13 mg/L.

Tesco British Natural Mineral Water is sourced from a spring in the Eden Valley, Cumbria. The water is bottled by Roxane (a subsidiary of the French company Sources Alma). This product replaced Tesco Ashbeck in late 2024, drawing from the same Eden Valley source.

Tesco British Natural Mineral Water is available exclusively at Tesco stores in the UK, typically £0.22–0.28 for 2 L (as of March 2026). It replaced Tesco Ashbeck in late 2024. Sold in still format.
