C EADO G RINDER R EVIEW
Dosing
The grinder itself is easy to use, the dosing system
works well and is fairly accurate with only a small
dose variance. Even when the level of beans in the
hopper is fairly low e.g. just visible at the neck of the
grinder, it doses well, with little "pop-corning". This
surprised me a little as the grinder has a smooth
domed nut and no auger.
There is a static/clump adjustment screw, where you
can adjust the balance between more static and less
clumps or vice versa. There is no magic here, it's a
metal flap to the burr chamber, on a hinge and a
rubber sprung flap mechanism that presses on
the metal flap with a pressure you can adjust.
More pressure = less static and slightly more
clumps, less pressure means less clumps, but more
static. I have left mine in the factory setting, as it
seems to work well enough. There are some small
clumps, but these resolve without any requirement
to stir the grinds and mostly fall apart when touched
or the portafilter is shaken.
In a coffee shop, when grinding directly into the
portafilter, you probably won't mind a small amount
of ground coffee dropping into the catcher tray
below. However, if your a clean freak like me, you
won't want ANY ground coffee dropping anywhere at
all. This can be easily prevented with the use of a
portafilter ring.
The 2 short Videos (links below), show this working.

Single Dosing
The practice of putting a measured amount of beans
into the grinder, and grinding until no more coffee
comes out. Many people like to single dose and
although this grinder will support single dosing, the
following areas should be considered.
Coffee tipped into the hopper won't stale very fast at
all and can happily be there all day or longer. The
grinder then is very easy to live with, with a 1.5 -2
sec purge to clear out stale coffee (espresso
setting), before pulling a shot. This purge is only
required for the first of a series of shots.
The burr chamber space holding ground coffee for
the sweeper arms to push out, is very small and the
arms move rapidly. Too light a tension on the anti
clumping system, trying to limit the retained grounds
below 2g, can cause ground coffee to exit the
dosing chute in a fine jet, missing the portafilter. The
anti clumping system should be set to it's minimum
tension, just before this begins to happen. If it does
exit in a fine jet sometimes, increase the
pressure on the anti clumping system (turn
adjuster anticlockwise) until this ceases to
happen.
With single dosing you need to allow for the purge,
and weigh out more beans than you need, then
hope the purge is gram accurate and then grind into
the portafilter. With the grinder being used in this
way, dosing is not so accurate to time and it can be
very awkward because you have to weigh
everything, including the purge. For me life is too
short for all this hassle and it never made much
difference in shot quality. My confession is, I used to
single dose for many years and even bought scales
for doing this. Finally I came to my senses some
years ago and stopped doing it, filling the hopper
with enough beans for the day is fine..
Grind Retention
This is the amount of coffee trapped in the lower
burr chamber, it has been ground, but remains in the
grinder. Retained grinds are normally removed by
"purging", grinding a small amount of coffee that is
thrown away, before grinding into the portafilter.
There is 2 types of retention for most grinders:
• The single dosing retention
• The normal use retention
Single dosing retention is what ground coffee is
left in the lower burr chamber after repeated pulsing
of the grind switch and brushing of the exit chute.
For the E37S it's approximately 2 - 3g, on an
unmodified grinder, with the anti static/clumping
mechanism in place...This is low for the class of
grinder.
