PERFECTING YOUR SKILLS - "NON-PRESSURIZED" SINGLE WALL FILTERS PERFECTING YOUR SKILLS - "NON-PRESSURIZED" SINGLE WALL FILTERS
STEP 3 - PREPARING THE SINGLE
• Place the single or double shot Single
Wall Filter into the portaﬁ lter. When
brewing into a larger mug, always use
the double shot ﬁ lter and only extract
2oz. If you require a larger serving,
add the hot water ﬁ rst and then extract
• Preheat the portaﬁ lter by placing
underneath 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 portaﬁ lter thoroughly before use.
Unlike the Dual Wall Filters, the Single Wall
Filters have no markings on the underside
of the ﬁ lter
(refer to page 8).
STEP 4 - GRIND SIZE & AMOUNT
When selecting the grind size it should be
ﬁ ne but not too ﬁ ne or powdery. The grind
will effect the rate at which the water ﬂ ows
through the ground espresso in the ﬁ lter
and therefore the taste of the espresso.
If the grind is too ﬁ ne (looks like powder
and feels like ﬂ our when rubbed between
ﬁ ngers), the water will not ﬂ ow 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 ﬂ ow
through the ground espresso too quickly.
This will result in an under-extracted
espresso lacking in ﬂ avor and without the
thick crema on the top.
When grinding for a Single Wall Filter using
a ﬁ ner espresso grind, you will need to
increase the grind amount to ensure the
ﬁ lter is correctly ﬁ lled.
STEP 5 - TAMPING THE GROUND
• Distribute the ground espresso
coffee evenly in the ﬁ lter and press
down lightly with the tamping end of the
Refer to ‘Espresso Making Tips’, page 31
• Clean any excess ground espresso
coffee from the rim of the portaﬁ lter to
ensure a proper ﬁ t into the group head.
STEP 6 - PRIMING THE GROUP HEAD
• Before placing the portaﬁ lter into position,
it is recommended to run a short ﬂ ow of
water through the group head.
• Place a container or empty cup under
the group head.
• With the portaﬁ lter removed, prime
the group head by pressing and holding
down the single or double cup button
for approximately 5 seconds.
Refer to ‘Manual Espresso’, page 24.
A pumping noise will be heard during
this operation, and water will run through
the group head.
• Use 1 level measure of ground espresso
coffee for the 1 shot ﬁ lter and 2 level
measures for the 2 shot ﬁ lter.
Refer to ‘Espresso Making Tips’, page 31.
STEP 7 - INSERTING THE PORTAFILTER
Place the portaﬁ lter underneath the group
head so that the handle is aligned with
the insert graphic. Insert the portaﬁ lter
holder up into the group head and rotate
the handle to the right until resistance is
felt, this will be at an approximate 90°
angle to the machine.
