01 Moca.
The perfect grinder.
Congratulations on purchasing your new Olympia Express
Moca coffee grinder.
For a perfect espresso you need to select a first-class coffee
blend, good water and an espresso grinder that produces perfect espresso powder—a precision-made machine that reliably
delivers optimum results. However, the most important thing
is the «Barista», the man using the machine. Only when all
factors are combined in the best possible way is the result a
truly exceptional espresso. It is the same as falling in love.
Therefore, choosing a particular espresso machine or grinder
is not a decision made solely made with the mind – you also
have to be in love with it.
The Moca has stood side by side with our espresso machines
since 1967. It is understated, but just as robust, durable and
built with the same premium materials—only first-class steel,
aluminium and genuine glass. Typical Swiss Design in
Swiss Made quality.
Key features: an electric espresso grinder with extra large
64 mm grinding burrs made of hardened special steel and
a 300-watt DC motor. It grinds quickly and continuously,
without heating up the beans. By means of a dial, the grind
can be precisely varied as required. The body consists of
mirror-finished stainless steel in the front, and the side
frames of resistant powder coated steel.

Four rubber feet assure a firm position. The sealed glass hopper
can hold approximately seven ounces of espresso beans. The
rotary slide on the bottom of the hopper closes automatically
when you remove the glass hopper by turning it.

Getting started.
Grind setting,
dosage and
other tips.
To enjoy the perfect espresso, we recommend the following
steps:
1. Carefully take your coffee grinder out of the packaging.
Remove all additional transport protection, e.g. plastic films.
Remove foreign objects from hopper if there are any.
2. Carefully read all the user manual.
3. Place the coffee grinder on an even and slip-proof surface
that is easy to clean.
4. Put the glass bean hopper 2 into the opening on the
grinder 3 and turn the container until it stops. The grinder
works only when the container is screwed in. Slide the
collecting vessel 8 between the feet 7 of the machine.
In order to obtain a perfect espresso, the grind setting needs
to be checked regularly and if necessary, adjusted, to avoid
problems with too fine or too coarse espresso. This procedure
may be necessary a few times within a week if the meteorological conditions (humidity, temperature etc.) change
considerably.
5. Fill coffee beans into the bean hopper 2 and put on the
lid 1 . Take care always to leave the lid on when grinding.
6. Plug in and switch on the appliance. When switched on I
the appliance is ON, when switched on the aplliance is OFF.
Fill the bean hopper 2 with roasted coffee beans. The
lid 1 seals the bean hopper 2 . The hopper can contain
about seven ounces of beans.
7. Put the portafilter onto the two rests 9 , pressing it against
the button 10 . When the basket is sufficiently filled (small
cone above the filter edge), pull away the portafilter.
In order to regulate the grind, turn the grind coarseness
dial 5 on the right side of the grinder 3 . Big dots indicate
a coarse grind, small dots a fine grind.
Please observe the following information:
If you want to change the grinding burrs towards a finer grind,
please do this when the motor is running in order to prevent
beans from being squashed between the grinding burrs.
• The domestic coffee grinder is only intended for stationary use.
Installation in vehicles of any kind is not admitted.
• For cleaning and servicing the machine must be disconnected
from the power supply system by removing the plug from the
power socket.
The optimal dosage for an espresso is 7,5 to 9 g.

Cleaning and
maintenance.
Coffee beans contain various oils, fats and waxes. This is why
you should clean the bean hopper 2 and the grinding burrs
from time to time with a damp cloth. Otherwise a bitter and
rancid smell may occur and the grinding burrs can plug up or
stick together. We recommend cleaning the grinder once or
twice per month and especially cleaning the output 4 from
coffee residue.
We recommend cleaning the grinding burrs regularly with
specialized cleaning products (e.g. Grindz™) or alternatively
with dry bread. Simply process/grind the cleaning product at
different grinds.
Clean the body with a dry microfiber cloth (high-gloss surfaces are scratch-sensitive). Wash the lid 1 of the bean
hopper 2 manually with mild soap. Do not wash the lid 1
and the bean hopper 2 in the dishwasher (aluminum changes
color and darkens with aggressive cleaning agents).

Servicing and
replacement.
Warranty, customer service
and disposal.
Alongside normal cleaning and maintenance, like all domestic
appliances, the grinding burrs have to be replaced at regular
intervals. This work must be carried out by a professional and
is required after about 550 to 660 lb. (250 to 300 kg) of ground
coffee.
From the day of purchase you have two years’ warranty on
the coffee grinder, subject to appropriate operation and care.
In order to promote the durability of the grinder, please observe the information provided on “cleaning & maintenance”.
In the event of a fault with your coffee grinder, it must
be repaired by specialists authorized by the manufacturer
or experienced experts. Please send us the completed
warranty slip.
The grinding burrs definitely need to be replaced if:
• the freshly ground powder is more than just lukewarm;
• oily bubbles are visible on the freshly brewed espresso
(which appear due to squashed beans or not thoroughly
ground beans);
Disposal
• the espresso grind is too fine (dust-like);
The packaging materials are environmentally friendly and
reusable. Dispose of the packaging at your local waste disposal centre. Ask your city or municipal administration for
ways to dispose of the coffee grinder in an environmentally
friendly and appropriate manner.
For disposal please observe the following information:
• Make the machine unusable in order to prevent any possible
danger emanating from it.

02 Espresso.
The importance of the water.
The quality of the water used is very important for the preparation of a good espresso. It is important not to use hard water, so
the taste and the aroma of the ground beans can fully unfold.
The importance of
the bean.
01
02
Most available coffee blends sold consist of two different
coffee blends, which differentiate in taste, caffeine amount
and shape. Arabica beans have a rounded cut in the middle,
are longer and flatter. The unroasted beans have an intense
green color. The cut on the Robusta bean on the other hand
is very straight, it is rounder and it is a little lighter in color
with brown or grey shading. Whereas the Robusta bean has
high caffeine content, the Arabica beans are milder and more
aromatic.
Even though common opinion suggests that pure Arabica
blends are better than ones with a small proportion of Robusta
beans, it should be noted that a small Robusta part (about
10 %) intensifies the taste and the aroma; it also simplifies the
espresso making procedure and compensates the traces of
bitterness in Arabica beans.
Even though the roasted beans are enclosed in vacuum orvalve
packages and do not lose their characteristics for many months,
they are, however, at their best within the first 3–4 weeks. We
suggest a dry and airy place for storage. Warmth, light and
strong aromas are to be avoided.
Espresso loses its aroma very quickly when exposed to air.
Therefore, the packaging should only be opened just before
filling it into the grinder. Because more taste is lost more
quickly when the beans are grinded, only grind as much as
you need.

Perfect espresso in
five steps.
A grinder is never used in isolation but is always a counterpart
to a coffee machine.
the right choice of basket (either for one or two cups). If you
select the wrong one, the outcome can be frustrating.
The preparation
The espresso machine should be switched on 15 minutes
before use, so that the right temperature exists in all parts of
the machine and the needed pressure has built up. Since most
parts only really heat themselves when the espresso is being
made, we suggest putting the portafilter with basket, but
without espresso into the brew group and letting water flow
through by lifting and lowering the lever. Repeat this action
two to three times until the brew group and portafilter are hot.
The tamping
The espresso in the portafilter basket has to be properly
tamped down to provide the flowing water with the needed
resistance: If the espresso is not tamped sufficiently, the
water will run through the grind without picking up the entire
aroma, if the espresso is tamped too hard, the water flow
can be very slow or not happen at all.
The ideal tamping force is around 33 lb. (15 kg). For training
purposes, we suggest that you use your bathroom scales, with
a little practice you will find out the perfect tamping pressure.
The grinding
For the use of the grinder, please consider the advice offered
to you later in this manual, entitled “The Moca”, the manual for
your grinder. The setting of the grinder is extremely important,
since it can alter the size of the grind. If the beans have been
ground too coarsely, the water will flow through the grind too
quickly and not all the desired aromatic parts will have been
extracted. The result is a thin espresso that is poor in aroma.
However, if the grind is too fine, the water will run through the
coffee very slowly and the espresso will taste wooden and
bitter.
The extraction
After tamping, place the portafilter, which holds the basket,
counterclockwise into the brew group. If water or coffee spills
out from the sides when you pull the lever down, you have
either put in too much espresso grind or the portafilter is sitting too loosely in the brew group. Once it has been tightened,
pull the lever up slowly, and then push it back down.
The result should be an aromatic, delicious espresso with a
beautiful hazel-colored crema.
Endless factors, such as humidity, air pressure and quality,
blend and roast temperature of the bean are of such high
importance to the outcome that there is not “the” right grind
setting. The ideal grind setting is achieved when it takes
20 – 30 seconds to pull a single espresso shot.
The dosage
It is important to aim for the right amount of espresso powder
when grinding directly into the portafilter. The ideal amount
would be between 7,5 and 9 g. Not following these guidelines
would mean that the same problems might occur as with the
too coarse or too fine espresso grind. Please pay attention to

Judging the
result.
If you have followed the instructions, the result is a perfect
espresso. You can judge this by the following criteria:
The first impression
The color of the crema shows the caramelized natural sugars
of the espresso bean. Ideally, the crema should be of a hazel
color with shimmers of red irregular stripes (fig. 01). The crema
should be three to four millimeters thick. It should not include
any big bubbles and last a minimum of three minutes without
breaking up or decomposing.
If the crema is light, thin, contains big bubbles and disappears
quickly, it is a sign of insufficient use of the espresso grind
(fig. 02). If the crema is dark brown or black with a white spot,
or it is too thin with the tendency to form a black hole in the
middle, the espresso grind has been exhausted (fig. 03).
The aroma
The espresso flavor consists of many different substances.
After the extraction of the shot(s), the aroma should be
intense but pleasant and slightly sweet. The espresso should
not be burned or taste wooden, smell musky or like tobacco.

01 Perfect crema
02 Light and thin crema
03 Dark brown crema with black
hole in the middle
03
The taste of the espresso should be perfectly balanced between sweet and bitter, including a rich body and a sufficient,
but not excessive density. It should never taste burnt or leave
a bitter aftertaste. A watery tasting espresso without the
needed density is normally due to badly brewed espresso.
A touch of hazelnut can develop when a blend with a high
Arabica percentage is used. An unclear, weak or lack of smell
is a sign of poor use of the espresso. A biting, sour taste or too
dominant smell means the espresso has been exhausted.
The taste
A perfect espresso needs no sugar, however, but sugar can
complete it. The taste test should be made without sugar,
to avoid distortion of flavor.
A bitter tasting espresso with an intense taste and not much
aroma plus an extreme aftertaste is normally the outcome of
a too intensely brewed espresso grind.
