7) General notes for coffee preparation
The porta lters must remain heated since
they are at the lowest position of the
group itself and they are partially isolated
due to the rubber gas et between them.
This can be accomplished by lea ing the
porta lters installed in the machine when
not in use. The porta lters may also be
acti ely heated. This procedure may be
carried out by brewing some hot water
through the porta lter then turning off the
water flow before ma ing coffee.
t is important to remember that coffee left
o er in the lters must be remo ed only
when you need to prepare another cup
and only at that time should you place a
new dose of ground coffee in the lter.
The si e of the coffee granules is e tremely
important in preparing a good cup of
coffee other than the type of coffee mi
used uite ob iously. The ideal grinding
can be determined by ma ing arious
coffees using the amount of ground coffee
that you would normally use for each cup
we recommend at least
g . The best
grinding is that which allows coffee to flow
out from the lter holder spouts neither
too slowly drop by drop nor too uic ly
uic light brown flow . general rule
is that a double dose should dispense
appro imately
cc or fluid o . of
espresso in appro imately
seconds.
