Just bought a new stove-top coffee maker, a Bialetti "Musa".
Had a similar (cheaper) one until this morning when I left it on the flame and ruined it.
Reading the instructions for the Bialetti raised two questions:
1. What level of grind is ideal?
The instructions say "not too fine" and leave it at that. I'd always put an "espresso grind" on the beans I put into my no-name, but essentially identical, device.
2. Is what comes out of these devices "espresso"?
Clearly I'm a coffee lover, not an expert. Google is kind of unhelpful.
