puck "suctioned" to group head - Breville BBE
Curious as to if this is any indication of something I can improve.
Essentially when I go to remove the portafilter the puck remains "suctioned" to the bottom of the group head instead of in the portafilter basket. Puck generally comes off cleanly into my hand when I touch it to break the seal with the grouphead. I use a calibrated tamper and have routinely checked I'm not overfilling with the Breville blade tool so I don't thing its that but I might be wrong.
Would this puck behavior be a symptom of grinding too fine or some other thing I can improve or refine upstream in the espresso process?
