    Eureka Mignon

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi everyone
    Has anyone had a Eureka Mignon grinder and had trouble with it clumping?
    Ive tried cleaning it out by tapping it on the bench and sucking it out with
    a vacuum cleaner.
    Any help would be much appreciated.
    Cheers Mick

    No one's chimed in on this so I'll give it a go. I've only played with the EM0480 and the compak k3 doserless and they all clump. I'm guessing most doserless will clump to some extent due to static build up, and where a doser will unclump a doserless will grind static and all into the portafilter. I know mazzer has a anti-static mesh that is fixed at the grind exit which helps with that. Not sure you can do more than what you are doing unless you find a way to get rid of static prior to the exit chute.

    Welcome to CS.

    Depends on what you mean by "clumping".

    Use of oily beans will cause "undue" (because there will always be some in a doserless grinder when grinding for espresso) clumping, as will use of a finer grind than required, and of course we are not able to see / check that from our screens!

    I personally havent found the Mignon to clump unduly (given my own grinding / brewing technique), so my first throught would be to check that you are correctly dosing your coffee filter. Operators that under dose, then rely on grinding finer to slow up the pour. That of course will cause the problem you are asking about.

    Also of course, make sure you are not using beans that are roasted darker than the cinnamon brown colour that we like to use for espresso in Oz.....OR if you like those southern Italian style black oily roasts, accept they will cause what you are apparently seeing.

    Hope that helps.

    Good morning

    After reading your advice i tried to grind a little coarser and got no where near the magic 30mil in 30sec so
    i looked at the beans Belaroma S10 there dark the are grinds fairly oily and roasted on 7/1/12 I dont know if the age
    is a factor or not. I bought them in July. I found a lot of buildup in the chute everytime i ground.

    Maybe i need to break out another bean variety and give that a go.

    Cheers Mick

    ...7/1/12...I hope that's M/D/Y...and not D/M/Y...anyway, after 4 weeks it's starting to go stale. Oily will clump, and if not cleaned out of your grinder will become like tar. Time to look for a good roaster.

    Where are you located? A number of the site sponsors sell freshly roasted beans (have a look at the Sponsors thread from the main forum page), or you can buy beans roasted to order through BeanBay (see tab at top of this page 'Beanbay' next to the tab that says 'Forum'), for which there are several delivery options.

    I live in Geraldton WA got some beans coming from Mista Barista Con Calcio I also recieved the
    Benito Secret Blend from DiBartoli with my Giotto V2.

    Just tried the Benito beans next to no clumping and a lot nicer tasting coffee, not bitter at all.
    Cheers

    Yes therein lies the problem. The coffee is too old. In order to achieve somewhere in the "spec" rate of pour, you will be grinding finer than you would for "freshly roasted" product. And that (the finer grind) causes the "undue" clumping I was referring to.

    And as you've seen, coffee that old does not satisfy......

    Glad you've sorted it.
