Highland Spring has a typical pH of 7.8 — mildly alkaline.
Highland Spring is the UK's best-selling natural spring water, sourced from a single protected, organic-certified catchment in the Ochil Hills of Scotland. The brand has bottled from this source since 1979 and remains independently, family-owned.
Rainwater filters slowly through the hills over several years, picking up calcium and other minerals from the underlying rock, which nudges the pH mildly above neutral.
Highland Spring carries a TDS of roughly 220 mg/L — moderate, not extreme — with calcium and magnesium contributing to the mildly alkaline reading.
Because it's bottled from one protected catchment rather than blended from multiple sources, the pH and mineral profile stay consistent batch to batch.
Yes. Highland Spring meets UK and EU natural mineral/spring water standards, and a pH of 7.8 is squarely within the recommended drinking-water range.
