What this means
Kettle & appliances
Some light mineral residue may appear in kettles over time, but significant limescale buildup is unlikely. No treatment needed for most appliances.
Espresso
A good range for espresso. Enough mineral content to provide body and balance acidity without posing a real scale risk to the machine. Most specialty coffee water targets fall in or near this band.
Filter & pour-over
Excellent for filter brewing. The slight mineral content adds body and sweetness without masking acidity, giving a balanced cup across most roast levels. This is close to the SCA's recommended range for brewed coffee.
Drinking & cooking
Tastes clean with a slight mineral presence. Good all-round water for cooking; it won't interfere with delicate flavours or leave noticeable deposits.
Bicarbonate
The buffering starts to become assertive: darker beer styles (porters, milds, brown ales) benefit from this level as it supports higher mash pH, but espresso will begin losing some of its brighter acidity, producing a rounder, heavier cup that flatters darker roasts while muting lighter ones.
