2.8 How to adjust a coffee?
After installation, the machine must always be adjusted
for the coffee beans to be used. Use this chapter to
help you do this. Once the coffee-making process has
been set, the user must always use the same bean
melange (mixture).
Coffee crème (lungo)
Always start with adjusting a
coffee
(usually button 1). First,
make a couple of coffees without changing the settings and
measure the brewing time of these cups of coffee.
The coffee brewing time is the time from the
moment the pump starts until the moment the
pump stops.
The brewing time of a coffee is dependent on two factors:
• grinding fineness
• coffee dosage
Adjust the grinder in such a way that a good cup of
coffee is made according to the brewing times shown
on the right. Make use of Chapters 2.2 to 2.4.
Espresso
Once the coffee creme has been set, there are some
more settings for the Espresso.
Because the same coffee grind is used for an Espresso-
based drink, the brew time for an Espresso (50 ml) will
be much lesser than for a normal coffee.
If there is still volume left in the brew chamber from the
espresso group (Standard: max. 9.0 g. / XL: max.12.5 g)
it is possible to increase the grinding time.
By increasing the grinder time for the espresso drink
in small steps, more coffee will be dispensed into the
brewer chamber. This creates more resistance and a
longer brewing time.
