The ultimate workflow machine, a new standard in high volume café performance.

The KB90 is the ultimate evolution of the Linea PB form. Designed specifically to optimize the workflow for the barista in the world’s busiest bars by improving the ergonomics and features of the machine. The Straight-in Portafilter improves the movements of brewing and removes the strain on the barista that causes repetitive stress injuries. Efficiency is also increased thanks to Steam Flush: after each extraction, a burst of steam from the steam boiler purges the brew path and is followed by a flush of hot water, keeping the group clean even during the busiest hours. This innovative function minimizes coffee residue in the group, and reduces the number of times baristas need to back flush during service. The KB90 allows for a new level of expression in machine design, based on 70’s retro design and the La Marzocco shield, the panels have been engineered so that virtually infinite customization combination can be created.


  • Straight-In Portafilter: designed to simplify the motions required to engage the portafilter and reduce the strain by 12 times on the barista for even greater performance and everyday usability.
  • Auto Brew Ratio (Optional): precision scales incorporated into the drip tray improve beverage consistency by stopping the extraction based on mass. The machine uses an algorithm called Drip Prediction to improve shot accuracy and ease of dialing in.
  • Saturated Groups: ensure unsurpassed thermal stability, shot after shot.
  • Independent Coffee Boilers: separate boilers for each group head allow baristas to optimize temperature for multiple coffees.
  • Dual PID (coffee and steam): allows you to electronically control coffee and steam boiler temperature.
  • Steam Flush: keeps the groups clean with an automatic burst of steam and a flush of hot water between extractions.
  • Programmable Doses: auto-volumetrics ensure repeatability and consistencty in high-volume settings.
  • Pro Touch Steam Wands: high performance steam wands that are cool to the touch


  • Stainless Steel Portafilters & Precision Baskets: for improved cup quality and consistency.
  • O-Led Display: intuitive programming simplifies the adjustment of machine parameters.
  • Proportional steam valve: lever-style activation for proportional solenoid steam valve eliminates the need for regular maintenance.
  • Hot Water Economizer: fine tune the temperature of the hot water spout.


  • Available Models: 2 or 3 groups.
  • Personalized Colors: customizable colors based on the RAL color system, on request.
