High TDS Mineral Water — Understanding total dissolved solids and mineral richness

“High TDS” is a useful starting point when comparing mineral waters, but the number tells only part of the story. TDS stands for total dissolved solids: the combined concentration of dissolved substances in water, commonly expressed in milligrams per litre (mg/L).

What does TDS measure?

Mineral water picks up naturally occurring minerals as it passes through its source. TDS gives an overall measure of dissolved content, including minerals such as magnesium, calcium, sodium and bicarbonate. It does not tell you how much of each mineral is present, nor does a higher figure automatically mean a water is healthier or better for everyone.

One Tree’s mineral profile

One Tree Mineral Water’s typical analysis lists a TDS of 1,500 mg/L. The same analysis lists magnesium at 110 mg/L, bicarbonate at 370 mg/L, sodium at 180 mg/L and calcium at 44 mg/L. These figures help explain why the water has a distinctive mineral character. For the latest analysis and any natural variation, refer to the current product label.

How does mineral richness affect taste?

The mix of minerals, rather than TDS alone, shapes a water’s taste and mouthfeel. Two waters with the same TDS can taste quite different if their mineral proportions differ. One Tree’s mineral-rich profile gives it a smooth, distinctive flavour, especially when served chilled.

How to compare mineral waters

Start with the TDS, then read the individual mineral concentrations and serving size. Consider your taste preferences and any dietary guidance relevant to you, particularly around sodium. TDS is a measure of dissolved content, not a medical claim or a standalone score for water quality. The best way to understand a mineral water is to look at its complete analysis and try it for yourself.
