A question for those of you who may be far more expert in the art than I am.
I recently bought naked bottomless portafilters for them. A 51mm for the Casabrews and a 58mm for the KitchenAid. Overall I rarely have any difficulty with them but I've noted especially brewing with the KA, it has a tendency to send little errant streams of espresso everywhere but to the cup. Wondering what I am perhaps doing wrong or could do better to get the nice streams. Otherwise love the results but oh boy I seem to be needing a lot of cleanup LOL
Any tips for someone new to "wide open" brewing?
