Over the course of two years La Marzocco worked with thirty of the world’s finest coffee professionals to design a machine. This group was known as the “Street Team”; the Strada, Italian for street, was named in their honor. Street Team input resulted in the most technologically advanced traditional espresso machine featuring traditional hydraulics and a barista-friendly design. This conical valve system assures progressive control of water flow and pressure via an internal orifice, before applying full pressure. The new conical paddle valve controls the pre-infusion while the volumetric pump is working at full pressure, therefore barista may also perform a pre-infusion on one group while the other is extracting coffee. This dynamic system allows the barista to reduce channeling for a more balanced extraction.
