2. Select the desired drink (fig. 21). If the drink has been pro-
grammed (see section "7. Programming drink quantities"),
the drink light blinks briefly.

Coffee preparation temperature
The water temperature is controlled during the entire prepa-
ration process to ensure its stability during the extraction step.
The Specialista Arte has 3 infusion temperatures* in a range
between 92 and 96 °C.
The temperature effectively utilized will depend typically on
the variety of been and the roast: Robusta beans require a lower
temperature, and Arabica beans a higher temperature. The
same applies for dark roasted beans or for light roasted beans,
respectively.

* This is the temperature of the water in the thermoblock.
It is therefore different to the temperature of the drink in
the cup or the temperature of the drink at the moment of
release from the outlets of the filter holder.
5. PREPARATION OF COLD BREW BEVERAGES
Cold Extraction Technology provides a method of preparing cof-
fee that uses cold water, or water at room temperature. Instead
of heat, a longer period of infusion is used to extract the proper-
ties of the coffee beans.
Proceed as follows:
1. Select Cold Brew
OK button turns blue.
2. To ensure the coffee circuit is cold, it will be advisable to run
a trial delivery first: accordingly, place a container under

the coffee spout (A10) and press OK: press OK again after
a few seconds to stop the delivery;
3. Remove and empty the container, then attach the filter
holder, with the appropriate dose, to the coffee spout;
4. Prepare a glass with 2-3 ice-cubes and position it under the
coffee spouts (fig. 24);
5. Press OK (indicator light blue): delivery will begin.
6. Delivery stops automatically.
Please note:
• Cold Extraction is a pressureless technology: consequently, the
pressure gauge does not move during delivery.
• The recommended coffee mill setting for Cold Brew beverages
is between 4 and 6.
• Make certain that the water in the tank is fresh. If the water
is one or two days old, empty the tank and rinse thoroughly.
Keep the water tank clean at all times.
6. MAKING MILK DRINKS
6.1 Frothing the milk
1. Fill the jug (C8) with the amount of milk to be warmed/
frothed, bearing in mind that the volume of the milk will
increase 2- or 3-fold (fig. 25). For a denser and more evenly
distributed froth, best results will be achieved using whole
cow's milk at refrigerator temperature (about 5 °C).
2. Place the jug under the steam wand and press the steam
button (B9) (fig. 26).
3. To froth the milk, rest the steam wand (A9) on the surface
of the liquid. This mixes air with the milk and steam.
4. Keep the steam wand in contact with the surface, taking
care not to let in too much air and create excessively large
bubbles.
5. Immerse the steam wand below the surface of the milk,
this creates a vortex in the liquid. Once the milk is heated
to the desired temperature, press the steam button again
and wait for the flow of steam to stop completely before
removing the milk carafe from the machine.
Barista tips:
• Fresh milk is best. Always use fresh milk straight from
the fridge.
