CoffEE doSE and tamPIng
•
Wipe coffee basket with a dry cloth.
•
Using single wall filter baskets, grind
enough coffee to fill the coffee basket.
You may need to experiment with the
GRIND AMOUNT dial to achieve the
correct dose.
•
Tap the portafilter several times to
collapse and distribute the coffee evenly
in the filter basket.
•
Tamp down firmly (using approx.
15–20kgs of pressure). The amount
of pressure is not as important as
consistent pressure every time.
•
As a guide to dose, the top edge of the
metal cap on the tamper should be level
with the top of the filter basket AFTER the
coffee has been tamped.
•
Wipe excess coffee from the rim of the
filter basket to ensure a proper seal in
the group head is achieved.
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 stabilise 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 centre 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 required volume.
•
As a guide, the espresso will start
to flow after 4–8 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 10 seconds, then you have
either over dosed the filter basket
and/or the grind is too fine. This is an
OVER-EXTRACTED shot.
