    Perhaps due to the so-called 'Nutating Tamp' that I've always used, decent distribution is taken care of.

    Never been a fan of introducing extra steps into the espresso equation though and have never found it necessary to deviate from what 'just works'...

    Mal.
    Same here; an extra step is just another opportunity for human error and inconsistency - and the need for one is generally indicative of an issue elsewhere ime.

    I use a grind on demand grinder and simply keep the level of beans in the hopper as low as possible to still prevent popcorning and inconsistent grind times. The throat on the ECM V-Titan is very narrow, which helps avoid any issues with stale beans.

      Same here in terms of keeping it simple. I don’t want to turn a simple espresso making exercise into some sort of complex alchemy.

      One thing I do think is important though is to make sure that the basket is dry but aside from that I time the Robur by estimation and almost always get it bang on. I aim simply to get the basket filled level with the top by smoothing over with my finger then just give it a good firm tamp. No Freemason type manoeuvres with the tamper.

      I get consistent results.

        I'm not so keen in the residual beans that sit in the neck of the grinder.

        Is anyone weighing the beans first and only dispensing say 20g at a time for each shot?
        Hi Dbun,

        I have been single dosing for at least 2 years in the M2M thinking that this method would keep my beans fresher everyday. However, I did notice that the beans deteriorate overtime by opening/closing my airtight container daily and a couple of shots a week were not as pleasant as the first ones. The containers I use dont hold more than 50grms of beans.

        2 weeks ago after looking at this post (thanks btw) I decided to give the "hopper" dosing a try. I added 300grs of beans, closed the lid and considering I only drink one milk coffee in the morning, the beans were there for almost a week. To my surprise I had the same experience on beans degradation that I had when single dosing.. no major difference but with some good advantages:

        consistency of my shots.
        -channeling was gone as I used to have minor channeling.
        -the workflow has improved as it is more convenient.

        I realised that the beans were deteriorating thanks to the hopper gate at the bottom and perhaps how loose the top lid was, so I decided to do some mods and since then, a week later, I can say that all my shots are as pleasant as the first one and way too consistent. Obviously you need to grind a couple of seconds to get rid of the old grinds stocked in the grinder from the previous day.

        So, this is what I did:

        1. I had a Bormioli Rocco - Ypsilon Brio Latte 220ml glass, that has a rubber wrap food safe approved. I removed the hopper's gate and took the rubber off the glass and wrapped it perfectly on the m2m hopper neck sealing the hopper's gate hole 100%, push it up as much as I could. This rubber piece fits perfectly in the m2m throat creating a "sealed" container extending the hopper capacity a little bit.

        2. For the top, I was lucky enough to see that my Airscape container middle lid was also a perfect fit creating a sealed container. Thanks to the function of this lid I also find out that not much air is introduced from the chute as it is normally full of grinds in between the chamber,burrs and chute. I am sure if one was to put his head in the grinder chamber not much oxygen would be there to survive :-). Leaving the chute opened also allows for fresher beans to breath a bit.

        As I said, I have been testing this mod for a week, full hopper, only one coffee every 24 hours.. and my palate is enjoying it.

        I decided to post my mods just in case they are useful for other users. I'll be posting some photos in the evening once I am back home.

        Cheers.

          Ah that sounds fascinating, good on ya for giving them mods a go! Yeah would love to see photos. And yes definitely consistency improves. At the end of a session I'll just bag the beans back up and get as many beans out of the throat as possible, takes no time at all. But I've always wondered about a method to keep the hopper lid and chute airtight... but definitely keep in mind that temperature and light also have an effect on bean quality deterioration. Also to let any remaining gas to leave the beans.

          One-way valve bags in a cool dark place works well for this, but I'm intrigued about your idea, and if you find that taste isn't affected that's awesome

            That's right, I wouldn't discard Single Dosing just yet for the summer days, I'll see how it goes, at the moment I am happy with the results.
            I am glad here in Melbourne we have almost 8 months of cool weather. I am attaching some photos now.. The grinder does not look that bad after all:

              i tried single dosing for the first time over the last few days whilst i was dialling in for a new basket and bean i started using.
              Main reason i did it this way was because the amount of retention on the mazzer kony e, so if i had to make an adjustment, i wasnt throwing away a heap of coffee.
              once dialed it i was getting consistent shots, and beautiful results, so decided to go back to my old method of putting in enough beans in the hopper for my daily amount of coffees.
              I was amazed at the difference, from single dosing and consistent shots, it went to chokers, so would have had to grind a fair bit coarser to yield the same amount of liquid in the same time. 32 sec up to 44 second.
              I am not sure if i want to re dial in for a hopper full of beans compared to single dosing.
              However i was not expecting this result at all, and if someone had told me this would have happened, i think i would have laughed at them.

                Are you talking about the issue on the M2M or on the Koney e? The M2M needs a decent dose of beans, or a workaround that simulates this.

                  my grinder is the kony e, and dare say works in the same way, requiring some beans in the hopper otherwise the grind completely changes as i have just found out.
                  Definitely need to go coarser when the hopper has beans in it compared to just weighing beans for each shot

                    Yeh, the M2M is a fairly extreme case of the need to charge the hopper though. The grind consistency changes really noticeably unless you have a decent payload in the hopper. I own and have owned a number of other grinders where the impact of the payload is far, far less that on the M2M. Great little grinder though.
