Mineral Water’s subtle taste and terroir are determined by the minerals it contains. The amount of minerals dissolved in water is indicated as total dissolved solids, measured in milligrams per liter (mg/l) or parts per million (ppm), which are equal.
TDS - Total Dissolved Solids in Bottled Water
A water’s TDS is normally made magup mainly of carbonates, bicarbonates, chlorides, sulfates, phosphates, nitrates, calcium, magnesium, sodium, potassium, iron, manganese, and a few other minerals. Gases, colloids, or sediment is not included in the TDS measurement.After mouthfeel, TDS is the second most important factor in matching water with food. The higher the mineral content, the more distinct a water’s taste can be. Think of low TDS waters as comparable to white wines, with a clean, neutral taste and less weight; high TDS waters are more like red wines, with a heavier, more substantial feel. Very high TDS waters feel distinctly heavy and may have an aftertaste, much like a big, bold red wine. Most mineral water you drink, though, probably has a medium TDS measurement and is more like a heavy white or a light red wine.
|Super Low||0 - 50mg/l|
|Low||50- 250 mg/l|
|High||800 - 1.500mg/l|
|Very High||1.500mg/l & over|
Regulations regarding TDS vary throughout the world. In the United States, bottled water must contain at least 250 mg/l TDS to be labeled as mineral water. TDS above 500 mg/l qualifies a water as -low mineral content- more than 1,500 mg/l allows a - high mineral content - label.
