COFFEE MAKING TIPS & PREPARATION
COFFEE MAKING TIPS
& PREPARATION
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, 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
pressure and help to optimize the
extraction regardless of the grind, dose,
tamp pressure or freshness.
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.
