    Eureka Grinder Dose Sensor

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi,
    Don't know if this topic has been covered elsewhere, but was wondering how the dose is measured on the Eureka grinder.

    Does the sensor measure the weight of the beans or does it simply go on time of grind.
    I had the machine consistently giving a perfect dose then changed the beans and then way too much.

    I would have liked the dose adjustment to have been on the outside of the machine as it needs to be played with a lot more than I expected.
    When the grind is made finer it packs down more, so the dose has to go up. It seems like you very often need to adjust the dose when you play with the grind.

    I think it is the Mignon although I am wondering why the question, surely all models with sensors would use the same sensing device.

    Mignon runs on a timer. Not by volume.
    The timing adjustment is located underneath which unfortunately makes it harder to make minor timing adjustment each time.

    Thanks for the response. I guess having a fixed time would naturally produce different dose depending on the beans and how easy they are to grind - amount of oil etc.

    Yes the adjustment is in a rather silly place and so small you can't be sure how much you have turned it.

    I found this review and he has the same comment about the adjustment.

    He also suggests breaking up clumps in the grind by stiring then.
    Surely this a bit fiddly and time consuming when you just want to do two cups.

    A suggestion for doserless grinders that has clumping issues is to use something like a small yogurt container, cut the bottom off and put it on your portafilter to make catching stray grinds easier (keep it cleaner) and then use something like a toothpick and give the grind a stir after to remove the clumps... which will also fluffs up the grind, and ensure more even distribution in the portafilter.... remove the yogurt container, than tamp...

    once you make it as part of your process, it becomes 2nd nature, and doesnt seem time consuming...

    but then, I single dose only, so I weigh my beans, and grind them individually for each shot... no need to worry about the timing... just how fine the grinds are and ensuring there are no left overs inside the grinder, and I tamp it evenly

    Hmmmmm....was just trying to help you get a relevant response....won't bother next time.

    The newest Eureka Mignon model now comes with the timer on the side. Just a little easier!! I tend to not use the timer anyway

    Wow, that seems like a bit of work.

    I was thinking that the Eureka saved me some effort as it is reasonably consistent with the dose, probably better than I could do stopping the grind when it looked like the correct amount was in the pf. Although not too much effort to run a toothpick through the clumps.

    No worries mate, I probably read it the wrong way.

    Are you saying you weigh the beans then only add the 7gms of beans to the hopper?
    How do you ensure there are no grinds left inside? Give it a bit of a thump or use a brush?

    Do you time the extraction or eyeball the quantity?

    I do shots using either 18g or 20g baskets.
    I weigh them individually and grind them. Any left over grind I use a little paint brush to brush them out of the chute area.

    I am using a mazzer super jolly though and have converted it to a doserless grinder. And my process has made it easier with minimal grind retention.

    Give it a gentle thump on the side to knock some grind out too

    I am now using the toothpick and find it does give a nicer looking puck.

    Not sure what you mean by that, but assume you weigh out 18 or 20 gms of beans and all the grinds go into the pf.
    You said you only make one cup, so I am guessing that is larger than a 200 ml cup, or is it double strength?

    Do you extract 60 ml?

    I normally make a double espresso for my morning pick up or a latte so I use 18g for it. So yes 60ml for 18g

    When I prepare my take away latte to work, I would use the 20g basket and pull around 75ml for a 400ml latte for the drive to work. Allows the taste to cut through the large amount of milk

    I never really use the single basket.
