tompoland To clarify: My experience of the niche as well as the Weber EG-1 was that the retention was pretty darned good at around 0.3 g but every now then they would simply drop a significant sized clump of coffee out and the Moca SD does not do that.
That’s not my experience with Niche. Like most I found first dose needed a couple of extra beans and then forget it. @DavecUK looked at carry over from that. As using the can I check weighed for yonks. I do get build up at the top of the chute but the rate per shot doesn’t show up on 1/10g scales. It doesn’t fall out. It may build up very quickly. Next time I clean it I will have a closer look at this and weigh it when I get it out. I’d like to find complete info on totally dismantling it as well.
There are 2 aspects on retention. What goes in comes out and what is left behind that may cause carry over problems etc. That can only be looked at from dead clean. Then comes the run the burrs in problem. ;) Even an SGP needs that and needs shots run to settle from clean. It can weigh in well but broken beans collect on top of the burrs. It settles to a point where one or two chips may or may not fall into the burrs. I’ve run a mazzer mini with what goes in comes out. I mentioned this to my son, One time he used it 1/10g short so I told him what to do to get the other ⅒ out.
dfk41 Now, I share an open plan kitchen so in my humble opinion, looks wise (not that I could give a monkeys!) the Niche fits far better into this arrangement.
Hence me mentioning the difference with this designer.
Talk about grinds and burrs. What chance does Niche have of producing the same grind as a Kony with it’s hopper on. I’d say zero. Probably more so than the difference on flat as more grinds need to forced out - the reason people were reluctant to use them - a lot more trapped grinds when the hopper is used,
