OPERATING YOUR BREVILLE DUO-TEMP™ ESPRESSO MACHINE
The Grind
If using a pre-ground coffee, ensure an
espresso grind suitable for espresso/
cappuccino machines is purchased.
If grinding coffee beans, the grind should be
fine but not too fine or powdery. The grind
will affect the rate at which the water flows
through the coffee in the Filter and therefore
the taste of the coffee.
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 coffee will be over extracted, too
dark and bitter, with a mottled and uneven
crema on top.
If the grind is too coarse the water will flow
through the coffee too quickly. This will
result in an under-extracted coffee lacking
in flavor and without the thick crema on the
top layer of coffee.
Tamping The Coffee
After measuring the ground coffee into the
Filter it must be tamped (pressed down)
using the flat end of the measuring spoon.
The ground coffee should be tamped
quite firmly.
If the coffee is not tamped firmly enough,
the water will flow through the water
too quickly and the coffee will be under
extracted. If the coffee is tamped too firmly,
however, the water will flow through the
coffee too slowly and the coffee will be
over extracted.
NOTE
The taste of your coffee will, of course,
depend on personal preference and on
many other factors such as the type
of coffee bean used, the coarseness
or fineness of the grind and the
tamping pressure (pressed down). We
recommend experimenting by varying
these factors to achieve the coffee
taste of your preference.
