  • Page 67: Calibration

    Section 4: Software 3033-004B Calibration Concordia refers to calibration as the process of adjusting the Xpress to extract the perfect drink. The Xpress may require adjustment to perform within specific extraction parameters using the customer’s choice of beans and settings.

  • Page 68: Calibrating Pump Pressure

    The bean hoppers only need to be configured if the machine will not be serving regular and decaffeinated espresso drinks. However, the Xpress can also be programmed to serve both espresso drinks and coffee drink. 1. Place coffee beans in the rear grinder.

  • Page 69: Espresso Extraction And Temperature Parameters

    Extraction Temperature Parameters Unless otherwise specified, the calibration goal for the Concordia Xpress is to extract a double espresso in 18-23 seconds. The extraction time for a single shot of espresso is based on the extraction time for a double.

  • Page 70: Calibrating Milk Timings

    One fluid ounce equals approximately 30mL. For example, calculating the brewed coffee timing for a 12oz cup would 12 x 30 = 360mL The default settings for brewed coffee are 12oz/355mL and 16oz/475mL. 4-16 Concordia Xpress Technical Support Manual 2900-300B...

  • Page 71: Calibrating Flavor Timings

    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.
  • Page 72 Pressure on the ground coffee is slightly increased. PRE-TREATMENT #7  Espresso grounds are pre-infused for 4/10 of a second.  A four-second delay before brewing.  Pressure on the ground coffee is slightly increased. 4-18 Concordia Xpress Technical Support Manual 2900-300B...
