PROGRAMMING YOUR GIOTTO
OR MOZZAFIATO
Modern coffee roasting companies, cafes and professional baristas
have very precise brewing preferences for their coffees. Specific
blends, single origins and roast profiles can perform better at
incrementally different temperatures.
Rocket Espresso machines measure the *exact boiler temperature
and display that reading on the controller. The table below shows the
boiler temperature and the corresponding group head temperature.

ADJUSTING THE GROUP HEAD
TEMPERATURE
1. Turn off the machine.
2. Remove the drip tray and portafilter.
3. Turn the machine on.
4. The display will initially show the software version and then
immediately show the boiler setting temperature.
5. To change the boiler temperature, keep key A pressed until the
display reads PrG. Then immediately press key B.
6. Press key A or B to increase or decrease the temperature. After 3
seconds it will memorise and display the temperature you keyed in.
•
Most espresso machines measure the water temperature used for
the extraction in the brew boiler. The boiler temperature reading
is then converted into a group head extraction temperature. This
information is misleading and inaccurate as the digital readout
on many machines does not display the real temperature at the
group, rather the temperature the manufacturer wishes the user
to see.
• Rocket Espresso measures and displays boiler temperature. The
table above indicates ‘real’ group temperature through precise
measurement using the SCACE meter.
