FROTHING MILK / MAKING CAPPUCCINO
To prepare a traditional cappuccino or latte, we recommend:
1. Prepare espresso first with a large enough cup according to "MAKING THE
ESPRESSO"part.
2. Using cold (39°F-50°F), fresh whole milk, and pour milk in 1/3 of cup/jug.
The density of the frothed milk will depend on the milk fat content. The
volume of milk will increase after frothing.
3. Using stainless steel, circular, rounded milk jugs, narrower at the top, with
a spout, necessary to make cappuccino decorations.
4. Before starting, it is important to slightly move the Steam Wand outwards
in order to insert the jug directly under it and facilitate the movements
required to froth the milk correctly.
5. Press steam button " " , it starts preheating, the steam indicator is flashing, when
machine preheating finished the steam indicator lights on.
6. Put an empty cup under the steam wand, turn the steam control knob
counterclockwise to the maximum position, release a little water in the steam wand,
and turn the steam control knob clockwise to turn off the steam after the steam
comes out.
7. Put the cup/jug with milk under the steam wand, place the steam nozzle just below
the surface of the milk. If it is inserted too deep, the milk will not be frothed; if it is
not inserted deep enough, big bubbles will be produced and then disappear
immediately.
When selecting a cup size, it is recommended that the diameter
of the cup be no less than 2.75inch. As the volume of milk will
increase after foaming, make sure that the cup has enough height.
Tips:

HOW TO USE
12
The steam pressure increases as the knob is rotated.
The entire operation should last no longer than 60 seconds.
To froth the milk correctly, the steam nozzle must always be
in contact with the milk and not with the froth. Therefore, as
the layer of froth increases, the jug must be slightly raised
trying to keep the nozzle in contact with the milk, without
touching the bottom of the jug.
Note:
It is important to keep the nozzle not at the center but close to the edge of the jug,
with an appropriate angle to produce a stronger vortex.
8. Rotate the steam control knob counterclockwise to let the steam comes out.
9. Once the desired frothing has been achieved, the steam nozzle must be pushed
deeper to heat the milk well.
10. Once the desired result has been achieved, close the steam control knob, by
rotating it clockwise, to stop dispensing steam and remove the jug.
It is advisable to always keep a hand on the rounded part of the
jug to feel the temperature increase of the unfrothed milk.
Tips:
To make the froth more compact, it is advisable to lightly tap the
jug on a flat surface after frothing.
Tips:
11. Pour the frothed milk into prepared espresso, now cappuccino is ready.
The Steam Wand may be very hot during and after use.
To avoid scalds, move it only by placing your fingers on
the rubber tip fitted on the Steam Wand.
