The KB90 is the ultimate evolution of the Linea PB form. Designed to optimize the workflow for the barista in the world’s busiest bars by improving the ergonomics and features of the machine. The KB90 offers one of the most exciting new features of the KB90, the Straight-in Portafilter. It continues to be the mission to create machines that make the lives of the barista easier and more efficient, and the KB90 embodies this philosophy.

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. High volume coffee environments demand that a barista can work fast and efficiently to produce drinks during the busiest periods of the day. The Straight-In Portafilter can noticeably mitigate the repetitive stress injuries occurring through its ease of action improving the natural workflow and output of barista.

Auto 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 backflush during service.

Auto Brew Ratio with Drip Prediction

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.

Independent Boilers

Separate boilers for each group head allow barista to optimize temperature for individual coffees.


PID Temperature Controller
Allows you to electronically control coffee and steam boiler temperature.

Saturated Group Design
Ensure unsurpassed thermal stability, shot after shot.

Thermal Stability System
Brew water is pre-heated before entering the boiler for increased temperature stability.

Easy Rebuild Steam Valve
Engineered so the valve can be serviced directly from the front of the machine without needing to be removed.

Hot Water Economizer
Enables you to fine-tune the tap water temperature for rinsing.

Barista Lights
LED lighting allows you to focus on your extraction and the cup.
