QUESTION: Does the new Eagle One by Victoria Arduino have preinfusion?
ANSWER: All Victoria Arduino machines have pre-infusion – technically a double pre-infusion (through the gigglers by the flowmeters and via SIS).
The SIS (Soft Infusion System) allows the water to make contact with the coffee with only water supply pressure and eventually ramps up to 9 bar once the chamber in the group-head fills to the top. This creates the best extraction – always – regardless of the user and/or tamp consistency. It’s also shown to minimize channeling.
Gigglers can be modified as well if requested, however, with the SIS there really isn’t a need to do so.
