  • K3 settings

    I got my new grinder and some fresh beans.

    The problem now is changing the grinder settings.
    Is there supposed to be a small screw outside the little knob on top?
    In the manual it shows one for locking and releasing but I dont have one.
    Or do I unscrew the allen keys on top to adjust the settings ?

    Please let me know, Im eagerly waiting to try it out!

      I think I figured it out. I just swivel the top and that changes the settings?
      I just made a coffee and its almost the worst Ive tasted.

      My shots take about 10 seconds, so I think Im doing some things wrong.
      Im not sure how full my portafilter should be and if the coarseness of the bean is too fine/coarse.

      Anybody able to give me some advice ?

        First you have to get your dose then you adjust your grind.

        10 Seconds sounds way to quick so it is a matter of adjusting your grinder to a finer setting.

        There are numerous checks. I havent used 5c test but you fill, tamp, and place a 5cent piece on top of the puck, lock it in and the 5c imprint should just be visible. Ultimately after you have brewed your shot remove the portafilter and there should be a slight impression of the shower screen and the puck should be firm to the touch. In terms of early warnings obviously if you try and lock the portafilter in and its resisting this is an indication of overdosing.

        When you get it right make note of how far you tamper travelled into the depth of the basket as this will be your guide for future; note try to tamp the same each time and dont adjust how hard you tamp to reach that point as this will change the playing field.

        Once satisfied with the dose then adjust finer to slow/coarser to quicken the pour. The aim being a 20-30 second pour for 30ml that doesnt blonde until right near the end of the time frame.


        As for tamping most important thing really is ensuring its level moreso than pressure. As long as its firm you dont need to tamp the crap out of it, you just want a firm, polished surface.

        Tamp with finger touching the rim of the basket as your sense of depth will be improved around the base of the tamper through the sense of touch rather than eyeballing it.

          Once you get pretty close to the correct grind, just a couple of mm adjustment makes a world of difference.
          So go easy on the adjustment once you start to get a slower extraction.

            Ditto both the replies above. Also....youll probably find it easier to get the dose/grind settings right using a double filter basket (wasted a bit of time myself stuffing round with the single).

              Okay.. Ive had some practise but I have more questions..

              When I dose I spill a fair bit, so often knock it down..
              I found because it fills in one spot of the portafilter I tried tamping it down then adding more on top otherwise I have to grind, tap, grind, tap X 5+.
              Double tamping bad ?

              My grind setting is getting close to the very max, so what sort of signs can tell me its too fine?

              Im still getting about 13 seconds pours.

                  Different everything I know but this is a video of my technique which you may find useful if you fast forward it you get some video of dosing, tamping etc.

                    Depending on the beans thats pretty close. Some roasts contain more oil than others so will clump earlier, but youre pretty close.
                    Have you tried tamping on a bathroom scale to see how much you are actually tamping.
                    I feel that double tamping may be a bit much.
                    With the K3 I can vary the grind so much, 18g basket, and get a 20 second pour easily. You can even slow it down to a 20ml in 20seconds if you so desire.
                    I pulled mine apart last night for a good cleanout for a new brand of bean, and it took about 4 baskets to get right for the new bean. (Spewin cos its a beautiful roast, never had anything like it. I call it Cherry Ripe  )

                          Great video.
                          It helped with ideas to keep clean but the portafilter sits on the k3 and the slide/guide just above so it leaves no room for a plastic sleeve?

                          The beans are coming up to three weeks old.
                          I used scales and even with 30 pounds pressure still 13 seconds.

                          I start timing when I see the first drop?

                          I think tomorrow Ill try the 5 cent test.

                            Timing starts the moment you pull the lever or press the button to activate the brewhead.

                              OK. So you might already be achieving a 20sec pour (which is in the ballpark). Does your coffee still taste bad?

                              Also, when you are adjusting the grind, are you doing this while the grinder is running? If not, might be worth backing the grinder off a little (towards the coarse end) and then re-adjusting while grinding.
