The Coffee System
The process of delivering espresso into a cup begins with whole beans,
stored in the bean hoppers, being fed to the grinders, ground to the
desired consistency, and then delivered to the brew chamber within the
brew group. Pressurized hot water is then introduced into the brew
chamber where the coffee is extracted from the ground beans and
delivered to the cup.
Only espresso-roast beans can be used in the Xpress.
Espresso Path
With ground beans in the brew chamber, the chamber is sealed and hot
water (195°F/85°C) between 135-140psi is forced through the ground
beans and through the lower piston. The “espressed” coffee is then
directed into the cup.
After the espresso is extracted, the used grounds are directed into the
grounds chute and into the grounds bin.
