5) General Notes for Coffee Preparation
The potafi lters must remain heated since they are partially isolated
from the group due to the rubber gasket between them. This can be
accomplished by leaving the portafi lters installed on the machine
when not in use. The portafi lters may also be actively heated.
This procedure may be carried out by activating one of the brew
buttons to fl ush hot water through the portafi lter then turning off
the water fl ow.
Other than the type of coffee blend being used, naturally, the size
of the coffee granules is extremely important in the preparation of
a good cup of coffee. Ideal grinding can be determined by making
various coffees using the amount of ground coffee that you would
normally use for each cup (we recommend at least 6g). The most
suitable grinding allows coffee to fl ow gradually from the fi lter
holder spout - neither too slowly, nor too quickly. A general rule is
that a double dose should dispense approximately 2 fl uid oz. of
espresso in approximately 25 seconds.
IMPORTANT
To improve fl avor, the temperature of water in the coffee boiler,
which has a direct impact on the groups, may eventually be
increased or reduced via the digital display (please consult the
Software Programming Manual for detailed instructions).
