Calibrating Flavor Timings
Since customers can choose to change the flavors used for drinks, the
headings in the FLAVOR TIMINGS software sub-category are generic.
For customers without custom flavor choices, the table below displays
the software generic headings and the corresponding default flavors.
For more information on how to calibrate flavor timings, please see the
Changing the Flavor Pour Rate topic in Section 9: Flavor System.
Espresso Extraction Pre-Treatment Options
During pre-treatment, a small amount of water is infused into the ground
beans. The grounds are then allowed to soak momentarily before the
brewing process begins. This pre-infusion process enhances the quality
of the espresso shot.
The Xpress has eight pre-treatment options, each varying in the specific
pressure used to pack the ground beans, the amount of water used to
pre-infuse, and the delay between the pre-infusion and the brewing. The
pre-treatment settings for single, double, and triple shots are individually
adjustable. The software category for adjustment is COFFEE PWDR
PRE. For directions on accessing the software menus, see page 4-4.
The default setting for a single espresso shot is pre-treatment
option #4 (regular and decaf).
The default setting for a double espresso shot is pre-treatment
option #1 (regular and decaf).
The default setting for a triple espresso shot is pre-treatment
option #0 (regular and decaf).
Pre-Treatment Options
PRE-TREATMENT #0
Pressure on the ground coffee is slightly reduced.
No pre-infusion water added.
No delay before brewing.
PRE-TREATMENT #1
The ground coffee is lightly packed, and then the pressure is
slightly reduced.
Espresso grounds are pre-infused for 1/10 of a second.
