Distilled Water
Distilled Water
Distilled water is a category, not a brand. It is produced by boiling water to steam and condensing the vapour, a process that leaves behind dissolved minerals, salts, and most contaminants. The result is water with effectively zero mineral content. It is not classified as natural mineral water, spring water, or bottled water in any legal sense: it is a purified-water product. Source feedstock varies by producer and may be tap water, groundwater, or any available supply.

Mineral character
By definition, distilled water has zero or near-zero dissolved minerals. Calcium, magnesium, sodium, sulphate, chloride, and bicarbonate are all at or below detectable levels. TDS is effectively 0 mg/L. This makes distilled water the zero baseline used in TWD blending calculations: it contributes no ions and dilutes any blend without shifting its mineral balance.
