Pressure & Pre-Infusion
Limiting the maximum pressure throughout extraction
produces a balanced espresso with an aromatic crema. Too little
pressure during extraction leads to espresso that is thin and
under-developed, too much pressure can lead to bitter flavors.
Extraction Pressure
Over-Pressure Valve (OPV)
limits maximum extraction
pressure for optimal
espresso flavor.
Low Pressure Pre-Infusion
Gradually increases water
pressure at the start of the
extraction to gently expand
grinds for an even extraction.

Temperature
Precise and stable water temperature is required for optimum
espresso flavor. Water temperature that is too low can lead to
espresso which is sour, too high can lead to ashy/bitter flavors.
Stainless Steel Espresso Boiler
Dedicated espresso boiler with electronic PID control delivers
precise water temperature to +/-2˚F
Actively Heated Group Head
Maintains thermal stability
throughout extraction.
PID controlled.
Stainless Steel Heat Exchanger
Delivers pre-heated water to
the espresso boiler via the
steam boiler, aiding
thermal stability for
optimal extraction
temperature.
Consistent average extraction temperature.

Simultaneous Steam
The ability to texture milk whilst extracting espresso ensures
the delicate aromatics of the crema are captured, producing
a creamier texture with more complex flavors.
Stainless Steel Steam Boiler
Dedicated steam boiler
delivers steam on demand,
allowing you to texture for
one cup or continuously for
multiple cups.
