I need something portable non in the sense that I want to grind coffee in the middle of the street, I'd bring it in the office on monday and bring it back on friday for the weekend.

For that purpose I could buy 2 stands (assuming they are not overly expensive) and place 1 at home and 1 at the office, and if they figure out a design that allows you to remove the entire grinder from above (maybe by detaching some sort of lever on the base) I can even see the idea of fixing the base to the counter with screws or something like that.

My only problem is that the instability is a reaction to a lot of force being used and this is because you have to work hard to grind, and that's what I want to avoid at all cost especially cause I'm weak.

Not to diss your opinions, but your responses continue to make me think you've never held the grinder and base I used in your hands which makes it hard for me to figure out your concerns, most of which don't seem like they are real. At least not for the version I played with.

My take was that the instability was caused by the lack of a place to hold on to. The only place to grab the grinder is almost centered with the axis of the burrs which because of the very short body gives you almost no leverage to keep it steady as you're fighting both with the beans and with the handle wanting to rock it back and forth. What you want to hold it by is the catch cup but when I tried that, the catch cup just came off.

At this point. I would consider it a manual grinder, not so much a hand held grinder. But as has been pointed out, you can press it down on a table to hold it steady which works, but the base changes everything, suddenly it's quite easy to use other than the current issue with the catch cup which I hope will be corrected before release.

Whether with the base it will still be to hard to crank, I can't say, it's certainly easier to crank than the Apex I own, but maybe harder than my Helor 101.

I don't think you understand what I mean




The catch cup is the bottom piece that is taken off to pour grind into what ever vessel you're using, you need to take the two pieces apart shown here regardless of a stand or not. It doesn't matter if you can pull the entire grind up from the stand or not, it is still a more complicated routine then if you could let those part be together and could pull a catch cup horizontally from the stand.

This would make it far faster then needing to pull said part apart.

You could easily design an integrated bottom part integrated stand with a catch cup you could move out like on electric grinders as a replacement part without changing the current design of the grinder.

I don't know if you've used other hand grinders, but the force required to grind was less than the conicals I have used (perhaps with the exception of those with cheap ceramic burrs that take forever to grind like in a Hario Skerton). With a handheld grinder the challenge with light roasts is maintaining grip on the cylindrical body. For the Pietro you can use body weight to stabilize the grinder even without a stand. I'm not particularly strong and I don't think you'd need to be.

OK< if you start from we're going to completely redesign the grinder and make it stand only, what you're showing would be better, but that's not their design goal at the moment and unless they decide it's not a portable grinder, that won't work very well as it would tend to slide out while being used freehand.

It's not a redesign of the grinder, the grinder will be exactly as it currently is, it is only a replacement bottom part you can use instead of the lower current catch cup, that you can slot the upper part into, it should be absolutely doable, however as I wrote earlier it would be a more expensive add on solution.

I would still get the base just to avoid that holding it down that much it also lift the handle a bit

I did a cupping and a blind cupping to compare my Pietro (pro-brew) with my Comandante C40 and 1zpresso K-Max.

Compared to both conical hand grinder the biggest difference was the sweetness and smoothness I got from the pro-brew burrs. C40 had a good fruitiness but I got a more defined fruitiness from the Pietro.
When brewing V60s the difference between pro-brew and the conical hand grinders (especially C40) aren't that big when grinding on 20/21 klicks and above but it gets bigger when grinding finer.
