The Prismo doesn't really increase the pressure in the chamber you can have by that much.
- the recipe itself is wrong, however I assume you're using the same recipe you got success with in italy, though that requires that the devices are the same kind (e.g. stovetop v electric) and powered the same way
- the device itself is broken
- the coffee you're using is different enough that the recipe doesn't work, or possibly the coffee you get at home is completely unsuitable for moka (wrong roasting, wrong grind size, ...)
Maybe consider watching James Hoffman's moka series for an intro? https://www.youtube.com/playlist?list=PLxz0FjZMVOl1Zot3qiJ-w...
The wines at the tasting in the winery are always amazing… and then you get home and open a bottle and it’s… meh.
The key issues were
* clean after every use (just with water)
* don't fill too much water, the water will touch the coffee for too long and make it sour, aim for just below the pressure valve
* don't tamp down the coffee grounds, just fill to the line
* dont have too fine a grind on the coffee
it sounds like a lot but I'm making great coffee now, i couldn't figure out the aeropress somehow
I love the Aeropress and have been rocking it since Obama's first term.
The AeroPress doesn't do real espresso, while the Nanopresso somewhat does. I never really got into the espresso that the Nanopresso produced though, while the AeroPress almost always makes a decent filter cup for me.
