It belongs to the Minimalist type in our sixteen-part typology, and the house tasting notes run bright calcium, lean body and crisp finish. Its pH is just over neutral, which on the palate reads as a touch sweet.

- Is South Downs hard or soft water?

- Can you use South Downs for baby formula?
- Probably not the first choice. South Downs falls outside the German infant-formula guidance because nitrate at 12.5 is over the 10 mg/L line. Pick a still water that clears all three limits, boil and cool it before mixing, and ask your pediatrician.
