PERFECTING YOUR SKILLS - "NON-PRESSURIZED" SINGLE WALL FILTERS

STEP 3 - PREPARING THE SINGLE WALL FILTER
•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 the espresso.
•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).
•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 4 - GRIND SIZE & AMOUNT
When selecting the grind size it should be
fine 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
fingers), 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
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 ESPRESSO
•Distribute the ground espresso coffee evenly in the fi lter and press down lightly with the tamping end of the measuring spoon.
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.
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.
