Deeside
Deeside is a natural mineral water from the Cairngorms National Park in Aberdeenshire, Scotland, bottled by Deeside Water. The source is associated with Pannanich Wells, filtered through Cairngorms granite. The TWD database also contains a separate entry for the Waitrose No.1 Royal Deeside product, which is bottled at the same source by Deeside Water for the Waitrose own-label premium range.

Mineral character
Calcium is 4 mg/L, magnesium 3 mg/L, sodium 6 mg/L, sulphate 6 mg/L, chloride 9 mg/L, and bicarbonate 26.6 mg/L. Hardness is 22 mg/L as CaCO₃ and TDS is approximately 60 mg/L. All ions are at very low levels, reflecting minimal mineralisation through granitic geology. This profile is essentially identical to the Waitrose No.1 Royal Deeside entry; both represent the same source water.
