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 reduce the extraction temperature
enough to significantly affect the quality
of your espresso. Always ensure the por-
tafilter and filter basket are preheated
with hot water from the Hot Water outlet
before initial use.
NOTE:
Always wipe the filter and filter holder
dry before dosing with ground cof-

neling' where water by-passes the
ground coffee during extraction.

ground coffee.
Dual Wall filter baskets regulate the
pressure and help to optimise the extrac-

Use the 1 cup filter basket when brew-

single cups or mugs.

If grinding coffee beans, the grind size
should be fine but not too fine. The grind

water flows through the ground coffee
in the filter basket and the taste of the
espresso.
If the grind is too fine (looks like pow-
