PRE-INFUSION

An espresso machine is said to use pre-infusion if it applies a moderate amount of pressure to the coffee before applying full brew pressure. Pre-infusion is often said to improve extraction by causing the coffee to swell, filling fissures in the puck that might otherwise cause channeling. Our premier range of espresso machines, the Appia manufactured by Nuova Simonelli in Italy offers you pre-infusion.
