C EADO G RINDER R EVIEW
The actual espresso crema is an even rich colour
with the extraction being very even throughout the
pour, gradually changing from dark to light. There is
nice dark flecking, with no sign of uneven extraction.
Taste is excellent for both single origin coffees and
blends (which can be tricky), flavours come through
clearly and are not muddy in any way. It has often
been said that flat burrs have thin body compared to
conical burrs, this was certainly not my experience
with the E37S. The body in the shot was good and
the overall taste experience, excellent.
Grinder Maintenance
The E37S has a nice method of mounting the burrs,
it's excellent quality and possibly a better design
than other companies doing similar things.
The burr chamber is split into 2 major housings
holding the burrs. These are held together with 3
substantial cross head machine screws. The screws
hold the housing together, but they do not act to
locate the burrs relative to each other. This would
create too much play and with wear, eventually the
burrs would fail to line up accurately. There is raised
sleeve in the top burr carrier that engages with a
collar on the lower burr carrier, to ensure the burrs
are absolutely aligned in the horizontal plane. The
top housing has almost no play in any direction,
making up to 2 of the machine screws a slightly tight
fit, because as tolerances are so close. On my
grinder 2 of the screws went in easy, but the back
screw (which had the slight damage on the
head), was the tight one. With the tolerance this
close, it's almost unavoidable to have 1 tight
screw. I would imagine this is true of the
majority of E37S grinders. It doesn't matter,
because that stainless steel machine screw will soon
make up the few 1000ths of an inch, by wearing the
softer aluminium upper burr carrier hole enough to
become easy to fit over time. For me the important
thing will be to remember to always fit the front ones
first, take up the slack, then fit the rear one and
tighten alternately finishing with the rear. The key
point is, the sleeve and collar on the burr
carriers are what align the burrs, not the 3
machine screws
The burr assembly and motor are rubber mounted
and effectively form a single unit independent of the
case. This also reduces the potential for burr
misalignment, as the minimum number of aligned
components are in the grind path, variance in the
case will not affect burr alignment and neither will
heat or impact.
The adjustment of the burrs themselves is via
movement of the top burr assembly within a
threaded collar. The threads are extremely fine, but
well out of the way of the coffee, so they don't get
contaminated with grinds. In addition, the burr
chamber can be accessed without having to
unthread the burrs and the grind settings are not
disturbed.
Apart from one or two little things, this is probably
the best motor/burr assembly method I have ever
seen from an engineering point of view. It's simple,
robust and has a minimum potential for variation in
burr alignment.
Cleaning is a procedure that only takes a few
minutes. Remove 3 machine screws, vacuum out
the chamber, clean with a brush, close the chamber
up and replace 3 screws. All your grind settings
remain unchanged and with NO chance of cross
threading a burr carrier as in some other grinders.
