Built for this water
Leucosia
Soft water arrives almost empty and leaves the cup thin, sharp at the edges, short in the middle. Leucosia is roasted longer and blended heavier to put back what the water will not carry: weight, sweetness, a low finish that holds.

Helsinki falls inside the zone the SCA Water Chart marks as its target (2.8–6.2 °dH) — unusual enough among the cities we publish to be worth saying.
The same number, three ways
- °dH
- 2.9–3.1 °dH
- °f
- 5.2–5.5 °f
- ppm CaCO₃
- 52–55 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, Helsinki ranks 41st by hardness.
