6.4 Preinfusion
Preinfusion is a process where the coffee grounds in the portafilter are moistened before the brewing
begins. This allows the grounds to evenly expand and seal any channels, ensuring consistent resistance
throughout the filter. This results in a more uniform extraction of flavors from the coffee. By default,
preinfusion is deactivated.
6.4.1 Activating the preinfusion
1. Switch the machine off.
