Degree of grinding
31
The degree of grinding determines the
contact time between the ground coffee
and the water, known as the extraction
time. Only when the ideal degree of
grinding is selected can the machine
dispense a perfect cup of coffee with a
fine, hazelnut brown crema.
Identifying the ideal degree of
grinding
There are various ways to tell whether
the degree of grinding is set correctly.
The degree of grinding is too coarse if:
- The espresso or coffee flows into the
cup very quickly
- The espresso or coffee tastes sour
- The crema is very pale and uneven
The degree of grinding is too fine if:
- The espresso or coffee flows into the
cup very slowly
- The espresso or coffee tastes too
bitter
- The crema is dark brown
Adjusting the degree of
grinding
If the degree of grinding is adjusted
by more than one level, the grinder
may be damaged.
Only ever adjust the degree of
grinding one level at a time.
Each time you adjust the setting,
start making a new drink so that the
beans are ground. You can then
adjust the degree of grinding by one
setting again.
The slide control for adjusting the
degree of grinding is located on the top
right behind the appliance door.
Open the service panel.
Push the slide control a maximum of
one setting to the left (for finer
grinding) or to the right (for coarser
grinding).
The degree of grinding you select will
be used for all coffee drinks.
Close the service panel.
Make one cup of coffee.
Adjust the degree of grinding again, if
required.
The altered degree of grinding will not
be used until after the second coffee
has been dispensed.
The grinder will naturally wear out
slightly over time. Set the grinder to a
finer degree of grinding if necessary.
