Built for this water
Parthenope
The reference blend, built for the middle of the spread. In Naples that is the high ground — the Vomero, Posillipo, Chiaiano, the Sanità — where the water sits near 21 French degrees. Dense, dark, long on the tongue. If your water lands in the middle, start here and do not move.

The water in Prague runs from 84 ppm to 257 ppm — a spread of 173 ppm that crosses Soft → Medium → Hard. That is not imprecision: a city this size is served by several waterworks, and the average describes no tap in particular. Check which works supplies your street before you trust a city figure, ours included.
The same number, three ways
- °dH
- 4.7–14.4 °dH
- °f
- 8.4–25.7 °f
- ppm CaCO₃
- 84–257 ppm
German utilities publish °dH, French and Italian ones °f, British and Irish ones ppm CaCO₃. Same water, three conventions — worth knowing if you compare your city with one abroad.
