PERFECTING YOUR SKILLS - Single Wall Filters (continued)
NOTE: You may need to try Step 4 and 5
a few times, slightly adjusting the
GRIND SIZE and GRIND AMOUNT
dials each time until you reach your
desired combination.
STEP 3 – PREPARING THE SINGLE
WALL FILTER
Place the single or double shot Single Wall
s
Filter into the portafilter. When brewing into a
larger mug, always use the double shot filter
and only extract 2oz. If you require a larger
serving, add the hot water first and then
extract the espresso.
Preheat the portafilter by placing underneath s
the group head. Rinse with hot water from
the group head by holding down the double
shot button on the front, right hand side of
the machine. Dry the portafilter thoroughly
before use.
Unlike the Dual Wall Filters, the Single Wall Filters
have no markings on the underside of the filter.
Place the portafilter into the grinding cradles
Press the FILTER SIZE button according to s
the filter size (single shot or double shot)
you select.
STEP 4 – ADJUSTING THE GRIND SIZE STEP 5 – ADJUSTING THE GRIND AMOUNT
When setting the grind size it should be
s
fine but not too fine or powdery. The grind
will effect the rate at which the water flows
through the ground espresso in the filter and
therefore the taste of the espresso.
If the grind is too fine (looks like powder and
s
feels like flour when rubbed between fingers),
the water will not flow through the ground
espresso even when under pressure. The
resulting espresso will be over extracted, too
dark and bitter, with a mottled and uneven
crema on top.
If the grind is too coarse the water will flow s
through the ground espresso too quickly.
This will result in an under-extracted espresso
lacking in flavor and without the thick crema
on the top.
When grinding for a Single Wall Filter using a s
finer espresso grind, you will need to increase
the grind amount to ensure the filter is
correctly filled.
To increase the grind amount, turn the s
GRIND AMOUNT dial beyond the DUAL
WALL setting to obtain the correct amount of
ground espresso.
