SKU m-la-marzocco-kb90

Faster workflow for high volume service

When orders stack up, the KB90 focuses on speed and repeatability. La Marzocco redesigned the portafilter system to improve workflow efficiency and reduce wrist strain for the barista.

Steam Flush runs after each extraction, helping minimise coffee residue in the group and extending the time between needing to clean the group during service.

Set coffee and steam boiler temperatures using the PID temperature controller and adjust key settings on the digital display. Lock in the portafilter using the Straight In system, then start the shot. If Drip Prediction is fitted, drip tray scales help stop extraction based on mass. After the shot, automatic steam flush purges the brew path, followed by a hot water flush.
