Pietro by Fiorenzato - vertical flat-burr manual grinders

Grinders are one of the keys to exceptional espresso. Discuss them here.

58mm burrs with multipurpose and filter-specific options
Lots of colors and finish options
No info on pricing

I just hope it's more practical to use than the other flat-burr manual grinder that's currently available, the OE Apex.

Well really this is actually true flat and not ghost, the OE isn't really a real flat burr grinder

Very neat. Wonder if it'll take 58mm SSPs. Looks like it may be a bit hard to stabilize though, I can't seem to see where your other hand grips the grinder.

This is really interesting. I've been considering making something like this, but I have too many projects already.
I'm really considering pre ordering if the price is at all reasonable.

Unless the grinding is very smooth and the silicon base is incredibly sticky, I can definitely see it slipping out from under the user for some particularly hard beans.

I'm probably wrong if they've done thorough testing, but it just doesn't seem that practical. Perhaps a bigger base similar to the HG1?

First Mazzer and then Fiorenzato. Old line Italian grinder companies are making hand grinders; Doug really started something.

Seriously. He's pushed hand grinding market forward exponentially.

This grinder looks interesting but I can't imagine it works well for espresso??

Super interesting, I might send them an email for more details. They're about 1 hour drive from me too so I could pay a visit :)

Apart from the usual alignment I'm wondering about how would the grind adjustment work. I was under the impression that adjusting flat burrs is somehow more finicky than that of conical burrs, and that the burrs should be turning while adjusting.

I would've liked some SSP options from the 64mm range (MP and cast steel) but again I wonder if the burr geometry here is different because of the very low RPM.

Only if you have beans on top in SD isn't really that necessary, several cannot also not run while adjusting.

Probably it is, also cranking even larger burrs will definitely make it harder, also I wonder if that low RPM is good. Normal we are 600-1400rpm you simply ain't going to crank that out.
