    Kony E vs Compak E6 OD

    Hi All,

    I've had a Kony-e at home now for the last year or so and it's an amazing grinder - 18g in 5 sec and relatively quiet. The major issue I have with it is grind retention...which I knew would be an issue in a home setting. I'm purging the first double shot of the day into the bin and then using the second, but finding the 3rd is often the money shot. So if I need to make a grind adjustment it's not ideal - end result is I'm settling for non-optimal grind settings rather than purge more coffee into the bin. I'm considering buying a Compak E6 OD and wonder what the grind retention is like on this grinder from those that might have some experience with it and any other thoughts.

    Have you considered the Kafatek Monolith? Single dose, almost zero retention (<0.5gm) Very small footprint. Mine has recently arrived and has replaced the Robur on grind duty in the kitchen (and which
    has been banished to the roastrery).

    Thanks for the suggestion chokkidog.

    Looks like a very impressive grinder and love the minimal retention but I'm looking at spending circa $1000 used so the Kafatek grinder probably won't be on the cards this time round. Maybe one day.

    For now I'm specifically looking for any input regarding the retention of the compak as that is a possibility at this point in time.

    Cool and good luck with your search! I'm not qualified to comment on hat particular model of Compak.

    I should mention though I am open to other suggestions like Chokki's. It was fun checking out that grinder for a dreamy 5 minutes....

    Kony E vs Compak E6 OD

    Hi pretzel, I have a compak E8OD so mine is a little bigger I think. I flush a gram or two through it each time but it seems to have only a little retention.
    I like the appearance of the compak but I canít stand the adjustment collar. I also removed the anti clumping flap because it increased the retention and didnít seem to help with reducing clumping at all. I think my next grinder will be a peak.

    Thanks very much for the input. Ok so it seems like retention is not a huge issue. Is it possible for you to elaborate on what you don't like about the adjustment collar?

    Hi Pretzal
    I use a Robur-E and single dose – 0.0g retention
    I'm constantly swapping beans and grind between double and triple baskets etc. All it cost was $0 to make a little plastic wedge out of ice-cream container lid to clear the chute after grinding. They're great grinders - why change?
    Cheers Matt

    Do you have any pictures of the wedge? Have you removed the anti clump mesh? Thanks for the input

    Not pretty, but it works
    Yes I have removed the mesh and the finger guard.
    You have to go substantially finer in grind (All loaded up when doing events I'm at 7 – but single dosing I'm around 4.5 on the crown wheel). I weigh in the beans, and grind it all into a plastic cup. Then I clean the chute out with the wedge, give it another grind hit which blows out anything left, and sweep again. Then with the aid of a jam funnel I dump the cup contents into the P/F and settle.
    It is a little slower and a little messier due to static – but a price worth paying IMHO

    I do something similar with my Mazzer Mini Matt.

    I use a 20 mm artists brush, sweep the chute after each shot (takes seconds) as you say very little grounds retained, certainly not enough to affect the following shot.

    To take the retained grounds thing a little further.

    I give the grinder a clean up every six weeks or so, remove top burr carrier etc and clean out any fines that have accumulated, have retained and weighed the accumulation a number of times, the total is always under 3 grams.

    Do I feel this build up has a detrimental affect on shots? not in the least.

    My feeling is there are other variables that come in to play that have a far greater affect than a few stray grains of stale coffee.

    i.e. Dirty group heads and porta filters immediately come to mind, have seen people obsessing over bean quality, roast times, distribution etc, remove the basket from their PF and it looks like you could grow mushrooms in the build up of gunk, don't even think of peering into the group head, will probably look like a biological warfare site.

    Coming from a mazzer where the adjustment collar moved smoothly the Compak feels somewhat ďstickyĒ. I also donít like the mechanism in which it locks the adjustment collar either, itís just weak.
