    Single dosing my Mazzer Mini.

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    As per a request in another thread, here's a run down on the way I single dose my Mazzer Mini, others may well consider it's more pfaffing around than they are prepared to go through, if so please disregard my comments.

    If your trying to single dose using the stock standard doser all you need is a scale, available for a few bucks on ebay and a small stiff bristle artists brush, I've cut the handle of the brush so it fits into the doser and at an angle, chisel shaped to scrape the delivery chute clear.

    Start with the grinder clear of loose grounds, ideally remove the top burr and give the grinding chamber a good clean, then reassemble, use the brush to clear the chute, then turn the grinder on briefly so that it throws any loose grounds into the doser and sweep out the doser, once you start using this method this step wont be necessary as you do it as part of the process at the end of each grind.
    I'm assuming you will have already removed the declumping/safety mesh from the delivery chute.



    • Establish the dose for your machine
    • Weigh the dose
    • dump the weighed beans into the hopper
    • grind, when finished lift the hopper while the machine is still running and brush any left over particles into the grind mechanism
    • Scape/brush out the chute, then run the grinder again to throw any loose grinds into the doser
    • Dose into your porta filter, I use an Orphan espresso funnel, keeps everything pretty clean, then clean up the doser with your brush, sweep any remaining coffee into the PF
    • At this point the grind/delivery path is clear of coffee grounds and ready for the next grind
    • Tamp and pull the shot.
    • Note well, keep your fingers well away from moving parts, this applies to the top burr area and the delivery chute, the moving parts will also chew up brushes, so don't stick a brush into the delivery chute with the machine running.

    I've explained the process using the doser, which I did for almost 8 years without drama, I have now modified my Mini with an after market hopper from a Mini E, it does make the process easier/quicker with no doser to sweep out, unfortunately these hoppers are not easy to come by and are a bit fiddly to fit

    The process sounds quite complex, in reality it only takes seconds from start to finish.

    I know there are excellent grinders on the market now that almost eliminate the need for this process, however if your in the position of having a Mini and either don't want or cant afford a new grinder this explanation may help, I'm happy to answer questions.

    To those who dislike or disagree with my way of doing things, sorry I have wasted your time.

    Sounds exactly like my procedure with the Robur
    It's really not that fiddly – all about practice and muscle memory!

    Same process as I use with my Robur, although haven’t found the need for a dosing funnel after doing the Shnozzola mod.

    Ditto for me with our Kony-E...

    Excellent write-up Yelta and will help lots of CSers (and others) to deal with single dosing.

    Great explanation Yelta.

    Agree this process seems very manageable and repeatable.

    I must admit to be mildly disappointed that no chickens were ritually slaughtered on full moons .

    Appreciate the time you devoted to this write up it’s certainly clarified a few things for me.


    Cheers.

    Thanks SP, takes me back to my days of writing work flow docs, you really had to have your ducks/chickens in a row.

    Thanks for posting that Yelta! As someone who is considering a Mazzer Mini for single dosing it's very informative/reassuring.

    There seems to be a bit of controversy on whether to remove this or not (some baristas even suggest just removing pieces of it!) with the argument for removing it to prevent build-up/retention and the argument for leaving it to prevent static/clumping. How do you find your grounds with it removed?

    No negative issues whatsoever, first thing I did when I purchased the grinder new.

    I suspect its more to stop clumsy/stupid buggers from stickin a finger in there than to prevent clumping.

    (some baristas even suggest just removing pieces of it!) I suspect that's code for ( I don't have the skill/dexterity to use a screw driver to remove it intact so I'll cut out the bits I can reach with a pair of small side cutters)

    On the other hand if your not comfortable removing it leave it in place and put up with the issues it creates.

    Is your grind setting different, between single dosing and having beans in the hopper?

    I mentioned this the other day in another thread, as an experiment, half filled the hopper of the Mini and ground/pulled a shot on the same setting, the difference was negligible.

    Single dosing my Mazzer Mini.

    Came to be an owner of a Mazzer Mini today. Was surprised by how quiet the grinder was.

    Yelta , can you elaborate further on what did you mean by “sweep any remaining coffee into the PF”
    This step as I understand it is over sweeping the grinds in the doser.

    Thanks
