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

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 is named for our Board Chairman, Kent Bakke. 20 years ago, Kent imagined one of the most exciting new features of the KB90, the Straight-in Portafilter. Kent has always seen La Marzocco’s 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 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.



Dual Boilers System
Separate boilers optimize espresso brewing and steam production.

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

Dual PID (coffee and steam)
Allows you to electronically control coffee and steam boiler temperature.

Saturated Groups
Ensure unsurpassed thermal stability, shot after shot.

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



Steam Flush
Keeps the group clean with an automatic burst of steam and a flush of hot water between extractions.
pro touch steam wands
High performing steam wands that are cool to the touch.
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.
digital display
Intuitive programming makes it easy to adjust machine parameters.
barista lights
LED lighting allows you to focus on your extraction and the cup.



auto brew ratio/drip prediction (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.
