Brewing Espresso; Pulling Shots - STARBUCKS Sirena User Manual

5 PULLING SHOTS

Warning! Do not remove the portafilter during coffee dispensing or immediately after brewing.
Wait 20 seconds while pressure is relieved in the filter: Danger of burning!
Warning! After pressing the coffee button(s), do not remove the portafilter immediately if
coffee does not flow out. In case this occurs, switch off the machine, and wait at 2-3 minutes
before removing the portafilter from the brew head.
The machine is fitted with a special pressurized portafilter (4), which allows you to pull either one or two
shots of espresso with the same filter basket for ground coffee (10).
• To brew espresso, the machine must be turned on with the ON/OFF button (15). Wait until the brew lights
(18 and 20) illuminate and remain fixed.
• During brewing, the machine ready lights located on the espresso buttons (18 and 20) may flash on and
off; this operation should be considered normal.
• Before use, make sure that the hot water/steam wand (6) is closed and the water tank contains enough water.
• Do not remove water tank when unit is brewing.

5.1 Brewing Espresso

Using the Pressure Adapter (rubber gasket adapter and plastic support peg)
The Sirena is equipped with a special pressure adapter (11a) and plastic support peg (11b) that assist in creating
a full body espresso with crema, even if the grind is not perfect. This adapter and peg are to be used when
making single and double shots, and will help you make a great shot of espresso with a high quality crema.
The pressure adapter (11a) and plastic support peg (11b) are offered as replacement parts by the manufacturer.
To order new parts, please call 1-800-933-7876.
• Insert the plastic support peg (11b) into the portafilter (4). Then insert the rubber gasket adapter (11a), with
the curved side facing down, as shown in Figure M.
• Insert the ground coffee filter (10) into the portafilter (4). (Fig. N)
• Brew a single or double espresso as described in the sections below.
Note: When using pre-ground coffee, you must first insert the plastic support peg (11b) into the
portafilter, along with the rubber gasket adapter (11a), and then insert the ground coffee filter (10),
as shown in Figure N.
Note: The Sirena utilizes a self tamping method when brewing espresso: the coffee is tamped when
the portafilter is inserted into the brew head. For optimal brewing, it is better to avoid tamping the
coffee in the portafilter.
Brewing a Single Shot
For best results when making espresso, you will need to ensure the unit is fully warmed up and the portafilter
is preheated. A preheated portafilter will result in a higher temperature of coffee and will help retain the espresso's
flavourful taste. We suggest you dispense a couple of shots of water through the portafilter to ensure it has
been heated to the optimal temperature.
• Insert the plastic support peg (11b) into the portafilter body (4) along with the rubber gasket adapter (11a).
Then insert the ground coffee filter (10) into the portafilter (4) body. (Fig. N)
• Holding the handle towards the left, fit the rim of the empty portafilter into the brew unit (13), as shown
in Figure P.
• Turn the portafilter from left to right until it firmly locks in place; you may have to hold the base of the
machine to keep it from turning.
• Release the grip from the portafilter.
