BEFORE BREWING: THE ELEMENTS OF A GREAT ESPRESSO

Before the Espresso Machine is even plugged in, you'll need
several elements to produce great coffee.

Fresh coffee beans

Great coffee can only come from fresh coffee beans, properly
roasted. Many baristas recommend buying beans roasted no
darker than a medium roast, the colour of which appears as an
even chocolate brown. This roast preserves the natural sugars
and flavour of the bean, which sets the stage for excellent
espresso. A medium roast is the darkest a bean can be roasted
without oils developing on the surface. Darkly roasted beans –
which appear dark brown or nearly black – look great, but the
extra roasting overwhelms the more delicate coffee flavours
and caramelises any sugars. A heavy "roasted" coffee flavour,
often bitter and sharp, will predominate with a dark roast.
To preserve the freshness of coffee beans:
Keep beans in an opaque, airtight container and store them
in a cool, dry place. Refrigeration is not recommended, as
condensation tends to form on the beans whenever the
container is opened. Freezing can help preserve beans stored
for an extended period, but it will also impair flavour.

If water leaks from the filter holder...
– the filter holder may not be properly attached
to the brew head
– coffee grinds may be clinging to rim of filter holder
or brew head gasket
– the brew head gasket may be dirty or worn
If little steam or froth is being produced, the...
– frothing boiler may not be at operating temperature
– " " dial may not be completely open
– frothing nozzle may be need to be cleaned
– water tank may be empty, or the frothing boiler
may not be filled
If the problem cannot be fixed with the steps above,
see the "Warranty and service" section.

Great tasting water

An often overlooked element of great espresso is the brew
water. If you don't enjoy the flavour of your tap water, don't
use it to brew espresso – use bottled, purified water instead.
Since it doesn't take long for fresh water to acquire a "flat"
quality and taste, it's also a good idea to change the water in
the tank often and refill the boilers after a long period of non-
use. Do not use highly mineralised water or distilled water –
they can damage the Espresso Machine.
The right grind — and grinder
Espresso demands a very fine, very consistent grind. Blade
grinders and inexpensive burr grinders usually fall short when
it comes to producing the grinds needed for outstanding
espresso. The best espresso requires a quality burr grinder, like
the KitchenAid Burr Grinder. A good burr grinder will maximise
the flavour and aroma of espresso by producing an extremely
consistent grind with very little frictional heating.
