Hi All

I just upgraded to a Mazzer Mini Electronic. 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. Anyway, I was wondering, can I assume that the grind quality that I am getting is the same as that from the Super Jolly? The burrs are exactly the same size (64mm). 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?

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.

Hi Mark,

I upgraded on the Mazzer too and only wish I would have done that earlier. That grinder is the perfect fit for my needs, grinds so much better and neater, and in the polished version I ordered it, pairs up beautiful to my machine. Since the burrs and the motor speed are exactly the same, grind quality and grind speed should be exactly the same on a Super Jolly. The stronger motor makes the SJ not faster, but more robust for commercial use. For home use I prefer the advantages that a doserless design provides me. Very happy with my new grinder, fast enough for my (home) needs and certainly not producing too much heat.

Ciao, Tom

Although they both have 64mm burrs, the Super Jolly is actually much, much faster than the Mini E. When I first switched to the Super Jolly for the Titan Grinder Project, I constantly overshot the target dosage. The "Duranium" burrs were even faster:

Both have exactly the same burrs, both have exactly the same 1400 rpm at 50 Hz, but much, much faster grind on the SJ: amazing! I'm not the greatest in physics, but do I miss here something? A different design of the burrs like those "Duranium" burrs can clearly make a difference, but with same burrs and same rpm? Please explain!

Ciao, Tom

EDIT:

OK, the "antistatic-fence" on the Mini E could take some speed, but who cares that much about speed in a home setting anyway? Grind quality should really be the same.

That could be it, I don't know. The difference in speed is unmistakable.

Although I haven't carefully compared them side-by-side, I did spend a couple months using both. My impression is that they're not the same grind quality. Maybe it's the compaction of the grounds caused by the doserless design, maybe it's my imagination, but I remember thinking the Super Jolly's pours were more consistent. I welcome the opinions of those who have compared them side-by-side.

Thanks for the feedback guys.

I don't know much about electronics myself but surely the beans provide some level of resistance to the motor when they are being ground up? Perhaps this is negligible but perhaps the 350watt motor of the Super Jolly doesn't slow down as much, in the "face" of this resistance, compared to the 250watt motor of the Mini Electronic...or something?! Or maybe I don't know what I'm talking about!? I'd just like to understand why there is this dramatic difference in speed.

Dan, I think you have a Mini-E at the moment, no? The SJ grinds a double in about 8-10 seconds. How long for the Mini-E?

OK, I just measured: It ground 15 grams in 20 seconds. Note the grind setting and coffee bean hardness affects the speed; it's currently about 5 notches finer than the factory "start here" setting. The estimate that the Super Jolly is approximately twice as fast sounds right to me.

Here is a grind test I did to measure my fresh from the box SJ for the titan grinder project.

UPDATE: Andy pointed out that the Mazzer Mini Electronic and Mazzer Super Jolly have the same diameter burrs, but they are not the same part numbers. According to espressoparts.com, the burrs are reference numbers 182D for the Jolly and 189D for the Mini E. I assume (*) the speed difference is attributable to a difference in the burrs' cutting angle.

(*) D'oh! I just returned Lino's Super Jolly this past Friday; I could have compared them side-by-side...
