NOTE
You will need to adjust the grind amount and
size if switching from a single basket to a
double basket, or vice versa.
The provided filter baskets are designed for:
1 CUP basket = approx. 8–10g.
If using pre-ground coffee, this is approx.
2 level scoops of the provided coffee scoop.
2 CUP basket = approx. 15–18g.
If using pre-ground coffee, this is approx.
3 level scoops of the provided coffee scoop.
If using freshly ground coffee, this is approx.
4 level scoops of the provided coffee scoop.
The reason for this difference is that pre-
ground coffee is often coarser and hence
occupies more volume than coffee that is more
finely ground.
NOTE
You may need to experiment with how much
coffee is inserted into the filter basket or how
long the grinder needs to run to achieve the
correct dose. For example, when using a finer
espresso grind with the Single Wall filter
baskets, you may need to increase the grind
amount to ensure the filter basket is correctly
dosed.
THE GRIND
If grinding coffee beans, the grind size should
be fine but not too fine. The grind size will
affect the rate at which the water flows through
the ground coffee in the filter basket and the
taste of the espresso.
If the grind is too fine (looks like powder and
feels like flour when rubbed between fingers),
the water will not flow through the coffee even
when under pressure. The resulting espresso
will be OVER EXTRACTED, dark in color and
bitter in flavor.
If the grind is too coarse the water will flow
through the ground coffee in the filter basket
too quickly. The resulting espresso will be
UNDER EXTRACTED and lacking in color
and flavor.
COFFEE DOSE AND TAMPING
Follow the instructions for:
1. Setting the Grind Size, page 13.
2. Setting the Grind Amount, page 13.
3. Selecting the Filter Size, page 13.
4. Automatic Dosing or Manual Dosing,
page 13–14.
5. Tamping the Ground Coffee, page 14.
6. Trimming the Dose, page 14.
PURGING THE GROUP HEAD
Before placing the portafilter into the group
head, run a short flow of water through the
group head by pressing the 1 CUP button.
This will purge any ground coffee residue from
the group head and stabilize the temperature
prior to extraction.
INSERTING THE PORTAFILTER
Place the portafilter underneath the group head
so that the handle is aligned with the INSERT
position. Insert the portafilter into the group
head and rotate the handle towards the center
until resistance is felt.
EXTRACTING ESPRESSO
• Place pre-warmed cup(s) beneath the
portafilter and press the 1 CUP or 2 CUP
button for the desired volume.
• Due to pre-infusion time, the espresso will
not start to flow immediately.
• As a guide, the espresso will start to flow after
4–7 seconds (infusion time) and should be
the consistency of dripping honey.
• If the espresso starts to flow after less than
3 seconds you have either under dosed the
filter basket and/or the grind is too coarse.
This is an UNDER-EXTRACTED shot.
• If the espresso starts to drip but doesn’t flow
after 8 seconds, then you have either over
dosed the filter basket and/or the grind is too
fine. This is an OVER-EXTRACTED shot.
