Kees van der Westen's See-Thru Espresso Pre-Infusion Perfection Contraption
Kees van der Westen, the man, may be camera-shy, but the newest engineering development for his Spirit and Speedster espresso machines proved most photogenic in Dublin this week. Making its global debut at the World of Coffee trade show is what the Kees van der Westen team calls a progressive pre-infusion cylinder system : PPIC for short. This technology allows a barista to take hands-on control of pre-infusion—that is, the initial wetting of the coffee puck that occurs before an espresso shot is extracted from a machine. By simply turning a knob, the barista can now manually modify the pressure involved in the infusion process. A glass cylinder lets the barista see the spring-loaded piston in motion, relying on its rise as a visual cue and reading the pressure gauge for instant feedback. Plus, since each group has its own knob, a machine can have as many pre-infusion sett...
