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.

The water in Brussels runs from 206 ppm to 421 ppm — a spread of 216 ppm that crosses 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.
Against the SCA target zone
At its softest, Brussels sits 1.9× 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
- 11.5–23.6 °dH
- °f
- 20.6–42.1 °f
- ppm CaCO₃
- 206–421 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, Brussels ranks 6th by hardness.
