single Wall Filters for aspiring Baristas
Experiment with grind size, grind amount and tamp The appliance is supplied with two
Single Wall
Filters - 1 x single shot and 1 x double shot. These filters provide no additional
slowing of the water flow rate, hence experimentation with the grind size, grind amount and
tamp force is required to achieve favorable results. These filters are suited to both pre-ground
vacuum packed espresso as well as beans ground fresh in the integrated grinder. A great
espresso is a balance of main flavor elements: acidity, aroma, bitterness, body, nuttiness,
and sharpness. By using the Single Wall
Filters you are free to explore the world of espresso
by adjusting grind, grind amount and tamp to extract a rich variety of flavors.
extracting an espresso
step 1 – Filling the Water tanK
• Ensure the charcoal water filter is securely fitted inside the tank. Refer to ›Care and Clea
-
ning‹, ›Installing the Filter in the Water Tank‹
• Fill the water tank with cold tap water to the maximum mark on the side of the tank and
slide the water tank carefully back into position at the back of the machine.
• Plug the power cord into a power outlet.
• Press the POWER button to ›on‹, the POWER button surround will flash while the machine
is heating. When the correct temperature has been reached, all the button surrounds on the
control panel will illuminate.
step 2 - pre-WarMing the cups
This will help maintain the espresso’s optimal temperature when brewed into the cups.
• The cup warming plate will start to warm as the machine heats.
• Run hot water from the group head without the
portafilter inserted by holding down the
-button on the front, right hand side of the machine, then place the cups on the warming tray.
note:
Check the water level before use and replace the water daily. The water tank should
be refilled with fresh, cold tap water before each use. Do not use mineral or distilled water
or any other liquid.
step 3 – preparing the single Wall Filter
• Place the single or double shot Single Wall Filter into the
portafilter.
When brewing into a larger mug, always use the double shot filter and
only extract 2oz. If you require a larger serving, add the hot water first
and then extract the espresso.
• Preheat the
portafilter by placing underneath the group head. Rinse with hot water from
the group head by holding down the double shot button on the front, right hand side of the
machine. Dry the portafilter thoroughly before use.
Unlike the Dual Wall Filters, the Single Wall Filters have no markings on the underside of
the filter.
• Place the
portafilter into the grinding cradle
• Press the FILTER SIZE button according to the filter size (single shot or double shot) you
select.
step 4 – aDJusting the grinD siZe
• When setting the grind size it should be fine but not too fine or pow
-
dery. The grind will effect the rate at which the water flows through the
ground espresso in the filter and therefore 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 ground
espresso even when under pressure. The resulting espresso 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 ground espresso too quickly. This will
result in an under-extracted espresso lacking in flavor and without the thick crema on the top.
step 5 – aDJusting the grinD aMount
• When grinding for a Single Wall Filter using a finer espresso grind,
you will need to increase the grind amount to ensure the filter is correct-
ly filled.
• To increase the grind amount, turn the GRIND AMOUNT dial beyond
the DUAL WALL setting to obtain the correct amount of ground espresso.
note:
You may need to try step 4 and 5 a few times, slightly adjusting
the GRIND SIZE and GRIND AMOUNT dials each time until you reach your desired com-
bination.
step 6 – grinDing the Beans
• Fill the hopper with fresh coffee beans.
• Ensure the
portafilter is inserted into the grinding cradle.
• Ensure the FILTER SIZE button reflects the filter size inserted in the
portafilter.
• For Auto Start and Stop Grinding - push the
portafilter in once to
activate the grinding switch, then allow the portafilter to be filled with
fresh ground espresso.
note:
To stop the auto grinding midway through a grinding cycle, push the portafilter in
once, or press the FILTER SIZE button.
• For manual grinding - push and hold the
portafilter in until the desired amount of ground
espresso has been delivered.
