What this means
Kettle & appliances
Limescale is a persistent issue. Kettles fur up quickly, and boilers, dishwashers, and washing machines all accumulate scale that reduces efficiency and shortens lifespan. Water treatment (a softener, inhibitor, or filter) is strongly recommended.
Espresso
Scale is a serious concern at this level: machines need regular descaling and filtration is strongly recommended. In the cup, the water has strong opinions. Light roasts lose their acidity and origin character almost entirely. But dark-roasted, milk-based espresso can work well here. London's coffee culture developed around exactly this kind of water: strong, dark-roasted coffee served with milk, where the density and body that hard water produces become a virtue rather than a flaw.
Filter & pour-over
Hard water hits filter coffee harder than espresso because the brewing ratio gives it more influence. Lighter roasts will taste flat and indistinct; the buffering neutralises the acidity that carries fruit and floral notes. Darker roasts produce a drinkable but heavy cup. If you're brewing pour-over with water this hard, the water is the first thing to address.
Drinking & cooking
Noticeably mineral-heavy on the palate. Soap and shampoo lather poorly. Tea may develop a film on the surface (that's the calcium reacting with tannins). Cooking water may leave a chalky residue on pans.
Bicarbonate
Significant buffering that pushes mash pH high enough to require acid additions for most beer styles other than stouts, and produces espresso that is notably flat and heavy, with muted acidity and a tendency toward a uniform, opaque flavour profile.
