4.2 Step 2 - Tamping
1. After grinding is completed, bring the tamping lever (A21)
down completely (keeping the portafilter in position) (fig.
14). For a perfect result, repeat the step twice.
2. Keep the tamping lever fully down when removing the
portafilter (fig 15). When done, return the lever to the at-
rest position.
3. Make sure you reach the perfect dose (see "The "perfect
dose"").
Please note:
• If residual traces of coffee are left along the edges of the
filter after tamping, this does not affect the quality of the
brew or the resulting drink.
• Draw the portafilter away from the tamper with the lever
still down, so that the surface of the compacted coffee stays
smooth.
The "perfect dose"
• The coffee filters have a mark inside to identify the level for
perfect dose.
The filter should be filled up to the level of the mark.
• Ensure the coffee is at the recommended dose level after
tamping. You may need to adjust the dosing dial (B1) more
times before reaching the perfect dose.
• If your coffee is over or under extracted and the dose is
within the perfect dose range, adjust the grinder settings
finer or coarser (see "4. Making coffee"). Over extracted
coffee (pouring too slowly) needs coarser grind. Under ex-
tracted coffee (pouring too fast) needs finer grind
Please note:
If any residual ground coffee remains after tamping, it will not
impact the quality of the extraction.
Tamping pre-ground coffee
For preparation with pre-ground coffee:
1. add the pre-ground coffee into the filter;
2. attach the portafilter to the grinder outlet;
3. with the portafilter attached, lower the tamping lever
(A21) as far as it will go;
4. detach the portafilter;
5. press the button for the desired number of cups (1x or 2x).
4.3 Step 3 - Delivery of hot drinks
1. Select the temperature (fig. 17) (see "The temperature for
brewing hot drinks").
2. Select the desired drink (fig. 18). If the drink has been pro-
grammed (see section "6. Programming drink quantities"),
the drink light blinks briefly.
"Perfect
dose"
3. Press OK (B4) to start brewing (fig. 8) (pre-infusion and in-
fusion). Delivery of the coffee will stop automatically.
The temperature for brewing hot drinks
The temperature of the water is controlled throughout the
preparation process to ensure its stability during extraction.
The Specialista offers 3 infusion temperatures* set in a range
between 92 and 96 °C (197.6 and 204.8 °F).
Depending on the variety and roasting level of the beans, a dif-
ferent temperature is recommended: Robusta beans and dark
roast usually require lower temperatures. Arabica beans and
lighter roast usually require highter brewing tempertures. Use
the table below as reference and adjust to taste.

This is the temperature of the water in the thermoblock.
It is therefore different from the temperature of the drink
in the cup or the temperature measured when the drink
comes out of the portafilter spouts.
4.4 Step 3 - Delivery of Cold Brew
• Select Cold Brew (fig. 19): the OK indicator (B6) turns blue
to show that a cold drink has been selected.
4. Place 2 or 3 ice cubes in the glass (fig. 20).
5. Press OK to begin delivery. Delivery will stop automatically.
Please note:
• As no pressure is produced to brew this drink, the manome-
ter will not turn to a higher position.
• Cold Extraction Technology: Fresh water is best: be sure
the water in the tank is fresh. If the water is a couple of days
old, empty and rinse the water tank thoroughly.
4.5 Step 3 - Delivery of Espresso Cool
When preparing Espresso Cool, use the dedicated filters (C4) or
(C5) provided for this drink (fig.21).
Prepare the "perfect dose" as described in "4.1 Step 1 - Grinding"
and "Adjusting the quantity of ground coffee in the filter".
Then proceed as follows:
