Lowest TDS

If you like a light, neutral-tasting water, start here.

Criterion: TDS or dry residue of 50 mg/L or less, as published: the EU “very low mineral content” level.

Why it matters

Fewer dissolved minerals means a more neutral taste and less limescale in kettles and coffee machines. WHO cites taste panels rating water under 300 mg/L as excellent, though very low levels can taste flat.
