What Los Angeles tap water does to your coffee
LA blends Colorado River water with local groundwater, and public datasets report roughly 157–180 ppm — at or just over the top of the ideal brewing range. Coffee tastes flat and muted at the high end, and more importantly your espresso machine and kettle will scale up noticeably faster than in a soft-water city.
The water comes from Colorado River, Sacramento Delta and local groundwater, supplied by LADWP. Figures above are published city averages — hardness shifts by neighbourhood and season, so your utility's annual water quality report is the number that actually applies to your kitchen.
How to fix it
Filter for coffee and descale on a schedule. A carbon filter helps taste; for espresso, cut your brewing water with distilled or use a dedicated in-tank filter. Plan to descale an espresso machine every 2–3 months rather than the once or twice a year a soft-water city gets away with.

Altitude: what 305 ft changes

Brewing in the Los Angeles climate
