Yeah, Missus Williams would not be proud of the way that I constructed that sentence.

What I meant to say is that stirring a naked shot will make it taste like the same shot pulled from a spouted PF.

And I'd also assume that it's for all of the reasons that we're all thinking.

Sorry for the inconvenient reading comprehension challenge, there, folks...

I pulled some more shots earlier today with the naked pf following the various advises and I managed to get better results but still not quite happy.

That's very true. I get a lot of crema with the naked pf. Actually the cup is fully of crema at 17 seconds. I stop the pull at 29 seconds and I get about 70ml. The cream collapses very quickly and after about one minute in the cup a very thin layer remains. The taste is getting better but still not as good as the one I get with the spouted pf.

I am not sure if the make of the pf also affects this: since I couldn't find a European stockist for Isomac Tea pfs the one I ordered and use was advertised for Vibiemme. It fits perfectly to the E61 group, no leakage and the Isomac's filters fit nicely. So again I assume I should not blame the pf but my skills.
