Built for this water
Ligeia
Mineral-rich water brings weight but mutes the top of the cup — and where alkalinity is high as well, it buffers the acidity and the cup arrives flat. Ligeia answers with higher-grown arabica and a shorter roast — more aroma, more lift, enough brightness to still read through the mineral.

At its softest, Rome sits 2.6× 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.
The same number, three ways
- °dH
- 15.9–19.6 °dH
- °f
- 28.3–35 °f
- ppm CaCO₃
- 283–350 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, Rome ranks 5th by hardness.
