CoFFee MaKing Tips
& preparaTion
PRE-HEATING
heating your cup or glass
A warm cup will help maintain the coffee’s
optimal temperature. Preheat your cup by
rinsing with hot water from the Hot Water
outlet and place on the cup warming tray.
heating the portafilter and filter
basket
A cold portafilter and filter basket can re-
duce the extraction temperature enough to
significantly affect the quality of your espres-
so. Always ensure the portafilter and filter
basket are preheated with hot water from
the Hot Water outlet before initial use.
noTe: Always wipe the filter and filter hol-
der dry before dosing with ground coffee as
moisture can encourage ‘channeling’ where
water by-passes the ground coffee during
extraction.
seleCTing FilTer BasKeT
single wall Filter Baskets
Use Single Wall filter baskets if grinding
fresh whole coffee beans. Single Wall filter
baskets allow you to experiment with grind,
dose and tamp to create a more balanced
espresso.
Dual wall Filter Baskets
Use Dual Wall filter baskets if using pre-
ground coffee.
Dual Wall filter baskets regulate the pressu-
re and help to optimise the extraction regar-
dless of the grind, dose, tamp pressure or
freshness.
Use the 1 cup filter basket when brewing
single cups and the 2 cup filter basket when
brewing two cups, stronger single cups or
mugs.
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 re-
sulting espresso will be OVER EXTRACTED,
dark in colour and bitter in flavour.
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 lacking in colour and fla-
vour.
CoFFee Dose and TaMping
• Wipe coffee basket with a dry cloth.
• If using Single Wall filter baskets, grind
just enough coffee to fill the coffee basket.
You may need to experiment with how long
the grinder needs to run to achieve the cor-
rect dose.
• Tap the portafilter several times to distri-
bute 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.
