STATEMENT: I am very pleased thus far and I can't believe that it has taken me so long to replace my old Solis Maestro! I struggled with grind consistency and I couldn't grind fine enough for certain blends even after doing the modification.

QUESTION: It's obviously a slower grinder, given it's weaker motor, but this shouldn't effect the grind quality, should it? Or have I missed something?

STATEMENT: An interesting thing, that I noted, was that with 220V/50hz AC(which is what we have) the motor does 1400rpm as opposed to 1600rpm on a 110V/60hz AC circuit, which would reduce the amount of heat transferred to the coffee during grinding.

Hey Chris,
I just upgraded from a Kitchenaid Pro Line last night. I too am AMAZED at the difference. Actually, my KA PL lasted one single day before I hit a solid VISIBLE wall of limitation.

Here is my problem, but it is a good "problem," I guess. I was trained on a Robur and the two bars I have had experience on had Roburs and Jollys. Look, I find myself waiting on the Mazzer. Heck, I waited on the Jolly, but I am really waiting on the Mazzer. It is just sooo sllloooowww compared to the Robur. I find the grind quality to be right there with the Jolly, no question on that idea.

But, this means one thing for me and my espresso setup: There will be a Robur in my house eventually and this mini will be subjected to Decaf work. Which is OK, my Decaf volume may just beat allot of coffee bar volumes, "per capita." For example, this morning I had a guest over, my wife and both of my girls. I pulled four doubles on decaf for the girls and one capp for both of them. That is five pulls. I pulled five regular shots for my guest and he had a capp. My wife had two doubles and a capp. I had five doubles and capp. When I sit at a bar for a while, I hardly ever see that decaf machine work.

Dan,

That's very interesting! Now I'm curious...I wonder if you could install the Super Jolly burrs in the Mini Electronic? Would those holes line up? You'd effectively have a doserless Super Jolly, albeit with a weaker motor that would need more recovery time...

@Wilson, For me, speed is not a huge issue as I usually just make doubles for myself and the occasional cappa's for friends that visit.

I also wonder if the parts are interchangeable. I had always assumed that they were the same part, as I'd never seen a 64mm Mini-E burr set on any online catalog. eg. Take espressoparts.com mentioned above - They have a 58mm burr set listed for the Mini and a 64mm burr set listed for the Super Jolly, but no 64mm set listed for the Mini-E. So I had always assumed that when I came to replace my Mini-E burrs that I'd have to buy the Super Jolly part.

Your comment about waiting on the SJ does not mesh with my experience. In the Titan Grinder testing, I found the Robur to be only slightly faster than the SJ:

Robur: ground 20.0g in 8-9 seconds, yielding 19.6g grinds
MXK: ground 20.0g in 20-22 seconds, yielding 19.2g grinds
Super Jolly: ground 20.0g in 10-11 seconds, yielding 20.0g grinds

I'd love to have a Robur for the grind quality and forgiveness, but you'd probably be better off with a Major if speed was the main issue. In general, conical grinders grind more slowly, due to slower rpms and a longer grinding path.

What kind of Robur?

I guess there is a noticeable difference in grinding speed between the 110v Robur with its 71mm burrs and the 3 phase 220v Robur with its 83mm burrs. Both spin at 500rpm. Note the difference in the picture down to the right:

Are there cafes, or anyone else using this second kind in the U.S?
If so, maybe this settles the difference in your observations?

Good point. We tested the 110V version.
