7. EKV 6600.0 café profi coffee machine
Whether as a café, espresso, late macchiato or simply with foamed milk – the type of coffee enjoyed
is a matter of personal taste. It’s a fact that the coffee bean brew has been the national beverage of
the European population since the beginning of the 19th century. Most people nowadays associate
drinking coffee with experiencing a unique flavour. The aroma and the diversity of selected coffee
beans will tempt you to a completely new culture of enjoyment. The sensuous enjoyment of coffee
hence expresses a personal awareness of life.
7.1 Fundamental principles
7.1.1 Order reference for fully-automatic coffee machines
The table enables you to break down the model identifier/designation and to recognise the design,
the size and the features of the appliances.
For fully-automatic coffee machines this is explained on the basis of model EKV 6600.0 M.
Model identifier Meaning Options:
EKV
EKV = Built-in
fully-automatic coffee
machine
6 Appliance width 6 = 60 cm wide
600 Fittings
The figures refer to the classification of the
coffee machine within the product line.
.0 Generation Modification options
M Design M = Metallic (stainless steel)
The appliance identifier hence means:
the EKV 6600.0 M is a fully automatic built-in coffee machine, 60 cm wide, a generation 0 appliance
in a stainless steel design.
7.1.2 General
The new Küppersbusch built-in fully automatic coffee machine makes coffee machines an integral
part of kitchens and attractive eye-catchers too. No valuable worktop space is wasted. Built-in fully-
automatic coffee machines offer more than extensive, convenient features. The elegant design is also
a real highlight. At home, in studio kitchens, in offices and in elegant business premises.
Training manual Section 7 – Page 4

Control unit and coffee dispenser
The smart electronic system regulates complex brewing processes and the clear optical display
guides users through all of the new coffee machine programs, hence making operating and
programming the machine child's play, even for inexperienced coffee makers. The various settings,
such as setting the brewing temperature, pre-brewing time, volume of coffee beans to be ground
and water hardness provide the new product with all that it takes to develop individual flavours. The
new EKV 6600.0M coffee machine enables you to experience the special flavour of coffee specialities
such as espresso, latte macchiato, cappuccino and lungo.
7.1.3 Structure and functioning of a fully-automatic coffee machine
Operating the built-in fully-automatic coffee machines is quite simple since they are operated from
the front. They are ready to use in no time at all – it’s all so easy. The panel opens very easily when
the bar handle is pressed. The water tank which is filled from the front, the coffee bean box and the
main switch are all located behind the panel.
All of the functions of the fully-automatic coffee machine can be set on the control panel. The
brewing unit and the adjusting knob for the grinding setting are located behind the service flap.
The height and the general depth of the coffee dispenser can be adjusted at the bottom. The
AromaControl knob is used to adjust how strong the coffee is when it is poured out. The collecting
bowl collects anything that overflows or drips and is used to deposit the cups. The jet can be used for
hot water, for steam to froth milk or for warming up beverages.

7.1.5 Steam appliances, semi-automatic, fully-automatic and pad machines
Numerous different systems for “coffee and espresso machines“ are available on the market. The
different methods of making coffee applied by the steam appliances and the semi-automatic, fully-
automatic and pad machines are described below.
Steam appliances
Water is heated up in a water tank for this standard type of espresso machine. Pressure builds up
when the water begins to boil. This pressure forces hot water through a sieve filled with espresso
powder. Disadvantage: the water that makes contact with the espresso power is very hot. This
releases bitter substances into the espresso, making it bitter and unenjoyable.
Portafilters /semi-automatic machines
With so-called semi-automatic machines or portafilter appliances a lot is automated, but not
everything. Espresso powder must be filled into the portafilter of the machine. Only then is the sieve
put into the machine. Water is automatically portioned with a pump at a temperature of more than
98°C, heated up and forced through the espresso powder at high pressure. Semi-automatic machines
need to be cleaned manually every time they are used, as oils contained in the espresso powder will
otherwise be deposited in the machine. They will become rancid with time and spoil the taste of
espresso.
Fully-automatic machine
Everything happens quite automatically here at the press of a button! Coffee powder is automatically
ground, apportioned and filled into the sieve (brewing chamber). The hot water is then forced
through the sieve and the coffee or espresso will be ready. The sieve will clean itself.
Pad machines
So-called pad machines are coffee machines that make coffee in cup-size portions. Coffee powder is
put into the machine as pre-filled pads. The advantage of this type of machine: no portioning is
required, since the pad that is put into the machine has already been filled with the right quantity of
powder. Disadvantage: the ground coffee in the pre-filled pads loses its aroma quickly if it is stored
for any length of time.
Training manual Section 7 – Page 8
Coffee machines

7.1.6 Keeping coffee hot
Coffee should not be kept hot on the hotplate of coffee machines or on a warmer. The reason: the
heat will cause the coffee to re-draw. This means that water will evaporate, resulting in the
evaporation of the fine coffee aroma. Coffee will not only lose its flavour; it will also taste bitter very
quickly.
7.1.7 Where can I get the freshest coffee?
Coffee bought at the small roasteries found in almost any larger town is freshest. These roasteries
generally sell high-quality beans which are roasted gently for a long time.
7.1.8 What is the difference between coffee and espresso?
Espresso and coffee are made from the same bean but the roasting times are different. Espresso is
roasted for longer than coffee. The result: espresso is tastier and has a stronger coffee flavour with a
lower acid content. Classic espresso generally comprises a mixture of Arabica and Robusta beans.
However, what distinguishes espresso and coffee most is the way they are made. Espresso is not
made in filter paper; it is made in a metal sieve. Within 10 to 12 seconds for automatic coffee
machines and within 25 to 35 seconds for espresso machines used on a cooker hotplate, water
heated up to 95°C is forced through this sieve. This means that the espresso powder only makes brief
contact with the hot water. All of the flavouring but only a little caffeine and few bitter substances
are dissolved in the powder. This is why an espresso, which is considered to be a black, particularly
strong beverage, only has half as much caffeine as a cup of coffee.
Training manual Section 7 – Page 9
Coffee machines

7.1.9 How can I recognise a good espresso?
Blend
Espresso experts swear by espresso blends which not only contain expensive Arabica beans, but also
comprise a 20% to 30% proportion of Robusta beans. This lends espresso a full flavour and a strong
aroma. The proportion of Robusta beans is also vital for the espresso crema. The high content of
ethereal oils in this bean makes the crema especially tasty and creamy. When buying, consumers
should make sure that the espresso has a robusta bean content of at least 20%. It will then have the
typical tart flavour and a super crema. The beans can be blended in specialised retail stores according
to personal preference.
Grinding setting
Espresso powder should not be too coarsely ground. The reason: the water would not make sufficient
contact with the powder for the flavours and aromas to develop properly. Espresso beans ground at
setting one or two are ideal.
Crema
What is also important for a good espresso is the ”crema“, i.e. the foam on top of espresso. It should
be a hazelnut brown colour and as thick as possible. A spoon of sugar will stay on top of a good
crema for two to three seconds and will only then submerge.
The crema is so important because it functions like a lid to protect the espresso. Precious aromas and
flavours do not evaporate so quickly. Instead they are contained in the espresso by the crema.
Temperature
A ready-made espresso should not be served colder than 80°C, as flavours and aromas will otherwise
not be able to develop their full potential. This is why connoisseurs drink their espresso quickly in two
or three sips as soon as it is served. This is how to get the most out of an espresso.

Thanks to its professional brewing unit the built-in coffee machine is able to make two cups of coffee
at once. This saves time, especially when numerous guests are being catered for.
7.1.13 Adjusting filling quantities to cup sizes
Households have different sizes of cups for coffee and for espresso. The fill-up quantity can be
adjusted quickly to the respective cup size so that a cup is filled up with just the right amount. Simply
place a coffee cup or an espresso cup under the coffee dispenser and press the button for espresso
until the right quantity is in the cup. After this, each time the “espresso“ button is pressed an
espresso cup will be filled with the same quantity, until a new setting is made. This setting can
naturally also be made for the “coffee long” and “coffee” buttons.

7.2.2 Grinding setting
Setting the grinder as you wish to enable the selected coffee beans to develop their full flavour to
perfection is child's play. The adjusting knob for the grinding setting is located on top of the brewing
unit behind the service flap. The knob can be set from fine to course in 10 stages. When the grinding
setting is adjusted no coffee beans may be present in the grinder.
Which grinding setting is best for coffee?
The quantity of coffee is important for the flavour and the aroma of coffee as well as for how the
coffee agrees with you. As a matter of principle: the stronger you like your coffee, the finer it should
be ground. Finely-ground coffee turns out stronger than when it is coarsely-ground. You must
however be careful: if the beans are ground too finely the coffee will quickly taste too strong and too
bitter. Too much flavouring and in particular too many bitter substances are released when the coffee
is brewed. On the other hand, if too little powder is used, coffee will taste weak and bland.
