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.

At its softest, Florence sits 1.8× above the top of the zone the SCA Water Chart marks as its target (2.8–6.2 °dH). Read that as a distance, not a verdict: the chart maps taste outcomes, it does not grade cities.

- 200 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.
Of the 47 cities we publish, Florence ranks 25th by hardness.
