    which grinder for rocket premium plus?

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi all, first time poster, so please excuse the "noobness"

    I'm using my rocket with rancilio rocky. I use double shot portafilter at all times as I normally make 2 cup at once - one for the missus. However I'm always making a big mess when removing the portafilter from the rocky. It's sitting too close to the doser and there is no room for me to move the portafilter without leveling the grind onto the table. I resort to dosing the grind into a container and scoop the grind into the portafilter - which is very annoying.

    To reduce the stress, I'm thinking i should replace the rocky with something else. I've been looking and reading and would like this grinder to be doserless, step-less or smaller steps compared to rocky, not too tall, and chrome finish to match the rocket. I am hoping to spend less than 600. I shortlisted a few: Compak K3, Macap M2M, or Nuovo Simonelli. I also come across a good deal for macap m4 but it's with doser which I don't really favor.

    I am hoping someone could advise which grinder is more suitable for the rocket. Thanks in advance.

    I actually ended up buying the mazzer mini electronic. The adjustment is very fine and I am still trying to get use to it. It is very well built in my opinion. Hopefully I can dial it in correctly soon. Any tips on getting there quickly without wasting too much beans?

    after much reading and research, I decided to change the burr to the ones from super jolly. faster grinding speed intrigues me. Just wondering if anyone regretted doing this and revert to the mini-e burr? and if so what's the reason/s? Thanks

    On a older thread, a test was conducted by the site sponsor Talk Coffee in order to see if this would put too much stress on the Mini's internals. Although the results were negative after testing it for about a week (the grinder stalled), others, including myself, have had no issues at all with doing this to the mini & I certainly would never go back to using the original burrs.

    As for dialing it in, the setting won't be the same on every grinder. My Mini E setting only ever goes between 0.9- 1.3 on the collar. If you intend to use a consistent dose then make sure you are using that quantity consistently while you make adjustments. Only go up 2-3 notches max at a time and come down 1 at a time if it chokes. I'm not fussed with tamping because I use a light touch and just use the tamper to level basically. Once you get used to it, and if you find the need, you might find yourself making half notch adjustments.

    Decent choice with the mazzer over the old rocky. I personally can't stand the Rocky's clumpy grounds. The Mazzer Mini E is still somewhat of a clump monster at times, but I use WDT & a Coffee Catcha so I don't have to break the clumps up in a separate container. The weather has been more forgiving lately so no WDT for me.

    We found a stall rate of about 25% when the mini-e was fitted with SJ burrs. Mazzer fits the Luxe with 61mm burrs and it appears that that's the upper limit for reliable operation of their 250W motor.

    When the SJ-E represents $240 at current RRP over the mini-e, I'd call it a no brainer.

    I cannot live the the glacial slowness of the mini-e. It's sort of like they fit the portafilter rest so that you can go cook breakfast while you wait. The SJ-E offers better performance and for me it's where Mazzer electronic grinders start. Regardless of all of this, the Macap M4D blows both of them into the weeds for Mini-E spend.

    All very good points Chris I wouldn't have bought it new & if I had been in that position it would have been the SJ-e while I had not yet tried an m4d.

    Having scored my used mini-e for $350 from a friend I'd say I had little choice in the matter. I'd be silly not to have taken the deal.

    Yes Gonzo. I'd agree that at $350, you got a good buy....

    Thanks Chris and Gonzo, I got mine used as well; which fits into my $600 budget. I'll definately appreciate the seemingly finer adjustment and speed on the m4d if I could afford it.

    I've got a diffrent experience with the rocky. It seems to clump less. Likely because i normally grind into the doser, which I then dose into a tray and transfer onto the portafilter. Seems to be more consistant as well - this could be caused by me giving the mini-e burr a good clean the the grinds are filling the "gaps" in the burr and grinding chamber. The mini-e seems to produce tiny clumps which is hard to break when I shake/knock the portafilter. I am sure the characteristics will change with the new burr, so waiting for them to arrive before I re-attemp to fine tune further and waste another round of beans.

    We must live in the Mythical "Clump Free Zone" here in Warwick, as none of the grinders I have ever used over the past 15 years or so, have ever created clumpy coffee...

    Maybe I just hold my tongue the right way...

    I had a laugh If only Brisbane were a clump free zone too.. I may sound like I'm being harsh on the grinder but I'm not that fussed. It's only due to using VST baskets that I started using WDT when dosing. If i wasn't using a VST, I wouldn't bother.

    Same thing here Mal
    Occasionally I get a clump - but usually when I've changed beans and the grind is too fine…

    Yes I was driving through Warwick last w/e - on the way to a trail ride.
    I swore the sign on the eastern approach said
    'Welcome to Warwick - Australia's Home of the Clump Free Espresso Grind'

    I thought to myself that's new! Wonder if Mal's seen it ?

    Left is sj burr.
