https://prima-coffee.com/learn/artic...te-bg-espresso I have a 1zpresso JX-Pro. Highly recommended. Price to performance is really good IMO. Very quick to grind and consistency is fantastic. As well as the ridiculous number of clicks. |

It’s just off of touching, so it’s as fine as it will safely go. It’s (the grind) is really the only thing I haven’t changed since I started with the Robot. It’s funny how easy the Youtube videos make it look!

Interesting! I dont know how the Robot works, but did you try tamping harder?

No prob. Out of interest, what dose are you using? You might get a better result with a slightly larger dose and a harder tamp to create more resistance. (that could of course result in channeling, though) If you did this, you could try a longer pre-infuse while holding the arms in place to allow the puck to swell to it's max size before continuing with the pull of your shot. Might also create some resistance.

I decided to order the ceramic burrs instead of buying another grinder to see how that works. I really like the Forte’ with its weight and time grind choices so we’ll see how the burrs changes things.

I know I’m over thinking this, but re grinds and extraction times I’m wondering if grinders that offer a larger distribution of particle size within a grind setting will produce a tighter puck with longer extraction times.
Here’s where I’m coming from: the steel burrs on my Forte’ BG are supposed to produce a mostly uniform particle size, which benefits V60 type extraction. On the other hand, the ceramic burrs on the Forte’ AP are supposed to produce a slightly finer particle size, but also more fines...or larger distribution of particle size for a given setting. If you have smaller particles filling in between (interstitial) the larger particles, it stands to reason that he resistance to flow will be increased...no? I’m just trying to figure out why I cannot build pressures that other Robot users are getting.

Yes, I agree with what you are saying in principle.
If it helps... here's my current grind. I know it's coffee dependent but photo's always help regardless IMO. This is a grind for a 17g in, 40g out. I go for a 10-15 second preinfuse at 2 bar, ramp up to 9 and back down to 6/5 bar by the end of the shot. This is the finest my Oxo burr grinder can do for comparison sake. I would agree that there are far less fines in here and even though it looks pretty fine, the espresso grind is still much finer. And the grinder itself can also go much, much finer.

Just finished a resto-mod on a 1978 La Pavoni Europiccola. Before and after image above. The powder coat was done by ArcaneMoto in Brooklyn. Just need to tighten the boiler flange and it's good to go. |

Wow that looks great! The inside of my base is rusted pretty bad. Wonder if I should get it powder coated!
