Coffee Making
Tips
PRE-HEATING
Heating your cup or glass
A warm cup will help maintain the coffee's
optimal temperature. Pre-heat 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
reduce the extraction temperature enough to
significantly affect the quality of your espresso.
Always ensure the portafilter and filter basket
are pre-heated with hot water from the hot
water outlet before initial use.
NOTE
Always wipe the portafilter and filter basket 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 and dose to
create a more balanced espresso.
1 CUP 2 CUP
Dual Wall Filter Baskets
Use Dual Wall filter baskets if using pre-ground
coffee. Dual Wall filter baskets regulate the
pressure and help to optimize the extraction
regardless of the grind, dose or freshness.
1 CUP
NOTE
Regardless of whether you use Single Wall or
Dual Wall filter baskets, use the 1 CUP basket
when brewing a single cup and the 2 CUP
basket when brewing two cups or a stronger
single cup or mug.
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.
