If the customer changes beans, the machine must be re-calibrated. The Extraction Goal The goal when calibrating the Concordia Model 2500s/i is to extract a double espresso shot in 16-22 seconds. Espresso Extraction & Temperature Parameters Once the machine has been calibrated, measure extraction time and drink temperatures to verify they are within operating parameters.
Before you start Step 3, a few things you should know… Espresso Grounds Ground espresso roast beans should have a texture between table salt and flour. The specific texture will ultimately depend on the grind. The grounds should be uniform in size. 4-14 Concordia 2500s/i Technical Support Manual 2900-233...

This pre-infusion process enhances the quality of the espresso shot. The Model 2500s/i has seven 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 wait time between the pre-infusion and the brewing.
