About
Water, checked against the maker's own words.
Mineral & Steam is a reference for people who own, or are choosing, a home espresso machine. We collect what each maker publishes about water, quote it word for word, and compare it with your water one measurement at a time.
230
espresso machines, from single-boiler to lever and plumbed-in
712
maker water quotes, each saved word for word with its link and date
376
products in all, each spec from the maker or marked "Not listed"
What we do
- 01
Read the maker
Specs and water limits come from the maker's manual, spec sheet or page, or its authorized distributor. When a maker doesn't publish a number, we say "Not listed".
- 02
Compare, don't judge
The check says whether a reported value falls within or outside a machine's stated water requirements. We don't rank machines or call one better.
- 03
Show the way back
When water misses a limit, we show ways to fix that measurement, and only where the maker's own words support them.
Lines we hold
What we don't do
- 01
We don't test machines by hand. We compare what makers publish.
- 02
We don't assess drinking-water quality or safety. Your water supplier's annual report covers that.
- 03
We don't sell anything. Every buy button goes to the store's own site.
- 04
A commission never changes which products we include or how we order them.
