I have juste bought a nuova simonelli musica / eureka mignon, and I m making test with a bottomless filter. Here are the pics: The extraction: https://imgur.com/a/v7uoFG6 The coffee after extraction: https://imgur.com/a/26Cnyi2
In the video we clearly see something is wrong. Then, when I check the filter I can see some channels in the coffee but I don't understand why.
I also notice some coffee on the edge, that could make me think tamper has not the good size. But, I use espro 58' the same I used on a Gaggia Classic, so it should be the good size for the musica.
Can you help me bring a diagnostic to improve my espresso please?
