How fine does the grind need to be for a pressurised PF e.g. DeLonghi?

Recommended Posts

I'm new to grinders - don't have one. I have a DeLonghi EC155 right now. I've been reading how you could have both a pressurised portafilter (standard) and mod it to be unpressurised, and I see the Gaggio Classic can be used both ways. As I understand it, pressurised PFs can take a slightly courser grind than unpressurised, where you need a nice tamped down puck to get a good shot.

 

So as a starter piece of kit before upgrading the grinder and considering going unpressurised, can I get OK results with a DeLonghi KG79? I realise that some of the grind may be uneven, but can it grind fine enough for a pressurised PF at least? I've also looked at the YT mod to grind finer, which looks fairly easy to do. So should I go ahead with an interim starter burr grinder or what?

 

Opinions welcome, as always.

Yes you can. Even better if you mod it so that it can grind finer. Don't expect the earth, but with a pressurised basket you will get good results with nice freshly roasted beans.

But, why bother? Go for a second hand more capable grinder and you won't have to pay much more than £150 or less. Saves the inevitable upgrade.

I've been looking on eBay, and there are always some big old commercial grinders at around £50-100. Good news, they grind true espresso. Bad news, they're huge and I have a small kitchen....... The smaller true espresso grinders tend to be the most expensive.

Small capable electric espresso grinder = mignon , unlikely you will get one or £50-100 .

Budget for closer to £200 even second hand.

The great thing is if you get a good grinder, you can whip the pressure gizmo out of the basket in a minute and the Delonghi will work pretty well. A cuisinart grinder worked well for me with the pressurised basket, £60-70 new. Or what about a hand grinder if you're short on space?

I picked up a Dualit 75002 cheap. I'll stick with pressurised for now - just want to see the difference with fresh beans. Then see where to go from there. I only drink decaf latte so may not be too critical, though I take the point that unpressurised is better in the long run even for milky coffees.
