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 Barcelona runs from 71 ppm to 362 ppm — a spread of 291 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.

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.
