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 filter basket dry before
dosing with ground coffee as moisture
can encourage channelling where
water bypasses the ground coffee
during extraction.
SELECTING FILTER BASKET
SINGLE WALL Filter Baskets
Use Single Wall filter baskets when grinding
fresh whole coffee beans.
Single Wall filter baskets allow you to
experiment with grind, dose and tamp to
create a more balanced espresso.
•
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.
DUAL WALL Filter Baskets
Use Dual Wall filter baskets if using
pre-ground coffee.
Dual Wall filter baskets regulate the pressure
and help to optimise the extraction regardless
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
When 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 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 flavour.
COFFEE DOSE AND TAMPING
•
Wipe coffee basket with a dry cloth.
•
Using Single Wall filter baskets, grind
enough coffee to fill the coffee basket.
•
Tap the portafilter several times to
collapse and distribute the coffee evenly
in the filter basket.
