Coffee Appreciation

usual espresso grind, and triple basket do the job for me

Mine does this too.
I've given up, for now.

Using a baked portafilter doesn't require anything different to a regular one. What it does do is show you flaws in either your beans (too old, shit supermarket beans etc) or your technique.
If it's pissing out everywhere then I guess the grind is far too course or the beans are too old. Or the tamping technique is flawed etc etc etc

As Bombcup often says, home espresso is a pain in the arse

Fresh Monmouth beans, awesome tamper technique... I think a naked portafilter just needs more coffee to stop it spitting... I've upped to a 20g shot which has helped bigtime so now I'm experimenting with grind to get the right flow... Guessing it'll be 5 clicks just like I've been doing all along, a super fine grind isn't working at all...
