Hi

Glad to be on the forum and looking forward to the wisdom of coffee geeks.

I owned a Gaggia Classic Coffee for about 9 years; purchased a VBM Piccolo a few days ago. Using an Isomac Professionale grinder.

The shots are better than ok but not at the standard I want yet - the coffee is still a little bit watery. The problem is when I use any of the obvious controls - increase the dose, grind finer or tamp harder - the extraction slows to a few drips. Any suggestions would be very gratefully received.

Cheers

MD

Welcome to CG.

Try to keep as many of the variables consistent. Do not change tamp pressure.
Try grinding the same amount for now. Keep the distribution technique the same, regardless of what it is. Make sure the coffee is tamped perfectly level. Otherwise, your pours will be uneven.

Your grinder, if new needs at least 5-10 #'s through it to "season" the burrs. It is a good enough, certainly more than adequate to yield a grind consistent enough for good pours.

Perhaps, watch some videos, and practice.

Thanks for the response

Doing my best to keep all the variables consistent. The grinder is several years old, and is as clean as I can get it without taking it apart. I'm going to purchase a new tamper as the one I have is a mm too small - but I can't see that having a major impact. I have watched several coffee-porn videos in the last few days as well.

I am puzzled though by the extraction. The first few mils are now coming through ok, then it slows to a drip? I'm not sure whether this is because of the grind, the dose, the tamping, or a mix of all three. If I ease back on any of them, the extraction is too fast.

Cheers

The first bit of the extraction is fine and then it slows down? I'm certainly no expert, nor do I have a ton of experience, but that almost sounds like a pump issue. Can you post a video? Was the Piccolo new when you bought it?

Thanks Dave

Machine is brand new - purchased last Thursday. And the pressure is showing steady at 9 bars.
