    Niche Grinder dosing techniques

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Niche Grinder dosing techniques?

    Wondering how others dose into the portafilter from a Niche grinder. So far I have tried:

    1 Dosing into stainless cup and lifting off without settling - grounds uneven and spilt everywhere.
    2 Trying to dose into plastic Decor cups that I pre measure the beans into - goes crazy with static and finely ground coffee goes all over grinder, shelf and self.
    3 Dosing straight into portafilter - hit and miss and messy. I don't have a dosing ring to try that.
    4 Dosing into stainless cup then taping lightly on mat before lifting the cup off - best yet but there appears to be a move away from tapping/settling grounds into PF (apart from gentle tap on the side.)
    see post 49410-clumping-does-matter

    Dosing is easier with 20g Pesado basket cf 18g Rocket basket as there is more room to play with.

    What do others do?

    grind into dosing cup, give it a shake and a few hard taps on the side, pour into portafilter with funnel while tapping on the side. no issues with clumping.

    So far my preferred technique is to pour the ground from the Niche's catch cup into the basket with a dosing ring. Then give it a WDT before tamping. It is possibly more steps than some prefer, but I find this workflow to be quite tidy (no spilled ground) and I get good results.

    Using Niche's dosing cup as intended (ie fit the portafilter on the grind cup and then flip them both together to transfer the ground) seems to demand a slightly more sophisticated technique for which I am lacking.

    I was doing a thing with the cup inverted in the portafilter, bang the spouts straight down on a rubber mat, then tilt 45 left and bang, then 45 right and bang, then straight down again, then remove cup and palm tap. Seemed to be too much faffing about and caused inconsistent channelling. Got a tallish funnel and have been tipping in from the side before giving a few palm taps to finish. Seems to be much more consistent. I'm guessing because the banging down method compacts the grounds a fair bit, whereas side tapping tends to leave them fairly fluffy until compacted by tamping, which is naturally more uniform. Also when dosing directly into the portafilter from my Atom I would then palm tap before tamping, so it could just be that's what I'm more practiced at.

    Thanks all. Clearly a funnel is the go. But what sort?

    1 Big standard plastic funnel
    2 Espreso dosing funnel
    3 Fancy funnel with distribution spike in the middle

    I'm using a different cup to grind into (tiamo from Dolo) as it doesn't protrude into the basket as much (felt i got more channeling but not proven) and the horizontal lip helps me hold it during gently and slowly flipping (anticlockwise) the portafilter & cup back over. Once portafilter back right way up and with the cup still on, i tap the portafilter on the lefthand size to move the grounds from a pile on the right to more central. Remove cup, quick tidy (or use a distribution spinny tool thingo) tamp and ready to go.
    All that take 5-10 seconds and now is pretty consistent.

    I usually cover the cup with my portafilter than turn both around shake it than give it a hard bang on the counter (using a bottomless) and shake and bang again, take the cup off (at this stage there should be a slight mound in the center or the side), give it a few taps to fill the void left by the cup, level the surface with distribution tool then tamp.
    Get occasional channeling but works 95% of the time.

    Tried many different techniques and always revert to: 20g weighed, ground into supplied cup, shake (or WDT with a skewer), mount, invert, level, light tamp. Bean dependent, very consistent, R58@6.5bar, 20gVST, 40g out in 40secs, invariably.

    40 sec shot? Isn't that over extraction?

    My main question, apart from avoiding spillage, was to settle/tap on the mat or not. It was the post on clumping and NOT tapping PF on mat that had me questioning my technique - see post 49410- "clumping-does-matter". But it has been fascinating and very helpful to hear what others are doing.

    I rarely (if ever) tap the PF on the mat to settle. Over exratacted? tastes awesome to me :-), - at a very fine grind the pull appears as if in slow motion and gathers early and evenly across the naked. On occassion the pull starts from the outside of the basket and quickly gathers to the centre - these shots (interestingly) are generally less balanced in the cup. I have had the odd shot run to 60secs! (new beans) and still tastes awesome.

    While a longer pour makes over-extraction more likely, there's a lot more going on. The grind, dose, temp etc all combine to affect the rate of extraction of oils from the ground coffee, and the point at which you 'should' cut the shot. You can get over-extraction at 20 seconds if you try hard enough

    It might be at 9bar (no guarantees), but noonar's shot is running at 6.5bar so unlikely.

    I've settled intot he following procedure:

    - place dosing cup on auto-taring scales (Brewista)
    - add 22.4g of beans.. (not entirely sure how i settled on this dose but it seems to work well for me)
    - grind into cup give it a slight shake
    - mount portafilter, invert and shake gently side to side to level any peaks
    - use BT wedge distribution tool and light tamp

    I used to use the supplied cup but now have the Decent stand and collar so dose directly into the PF and the use a distribution tool after a single tap and finally the Decent tamper. Never get channeling just coffee coming out of the centre of the naked portafilter.

    Brilliant Bob, been waiting for someone to provide some feedback on your Decent stand and Niche set up, great timing as I have been mulling over having a cylindrical timber stand made that does the same but not sure where to look/start. Might just go with the Decent set up instead.

    Bob_Weis I've been trying to find an Australian seller of the Decent stand and collar. Can you advise as to where you got yours from?
