Subject: With Mazzer Mini E: How to prevent clotting and getting a good distribution
As I wrote in an earlier post, my Rancilio Silvia did not pour evenly in
both cups, filling the left one quicker than the right one. Meanwhile I
leveled the machine more exactly, paying attention to the group head
instead of the top of the machine and it is already better now. However
I also suspect that the distribution and leveling is part of the
problem. I did a quick search and found this post of RandyG:
http://groups.google.com/group/alt.coffee/browse_thread/thread/31e62d230e31c9f9/bb8a7be07571a9b4?lnk=gst&q=polish&rnum=11#bb8a7be07571a9b4
and tried to copy this method. The difficulty however is that the ground
coffee dispensed by my Mazzer Mini E, is kind of clotted, or in small
clumps, probably caused by static electricity. I already catch the
coffee in a small plastic container and pour it into another container
(I remember having read something about this method) to prevent this
clotting, but unfortunately this does not help much.
Anyhow, this clumps obstruct an even distribution and probably this also
is a cause for my uneven pours.
Is there a, preferred simple, solution for this ?
Btw, I assume that the polishing has to be done with less pressure than
the final tamping ?

as the dosing chamber does look like one of those sifters

shouldn't they make grinders that sift the coffee when you click it
over (whatever thats called), like a flour sifting thing. I think that
would be cool - or is that not cool?

if thats cool then thats my million dollar idea, maybe i could mod my
rocky to do this someday.

A similar approach is discussed here:

http://www.home-barista.com/weiss-distribution-technique.html

I don't go to the trouble of using a yogurt cup. Using a doserless
grinder, I stop the grind when the PF is about 3/4 full and stir the
ground coffee around with the sharp end of a very narrow chopstick (I
use the bigger end to get the grinder going when the beans get stuck -
multi-purpose tool), breaking up the clumps and getting the grounds
distributed to the edges of the basket. Then I fill the rest of the way
and break up the few additional clumps while levelling. I'm still a
rank beginner at this, but even as I've experimented with grind
settings, tamp pressure, etc, my pucks have come out very cleanly, so I
think I'm getting pretty even distribution for the most part.

I've pvc-taped a couple of very thin wires (coated florist wire) to the
"other" end of my grinder brush. My routine is to gently press the
mounded coffee in the pf with the cup of my hand, give a stir with the
wires, and then level and tamp as usual. "Better" results are not
striking with any single shot, but I do notice a trend toward less
channeling and nicer pours.
