The kb90 sets a new standard in high volume cafe performance
striving to make great espresso faster, cleaner and easier.
The KB90 is the ultimate evolution of the Linea PB form. Designed specifically to increase speed of service in the highest volume cafes while easier for the barista thanks to an improved workflow. La Marzocco has redesigned the portafilter system to improve workflow efficiency and to reduce the wrist strain of the user. Efficiency can also be increased thanks to Steam Flush: after each extraction, a burst of steam from the grouphead is followed by a flush of hot water, keeping the machine clean even in the busiest rush hours. This innovative function minimizes off flavored buildup, and increases the time between having to clean the group. The KB90 allows for a new level of expression in machine design, the panels have been engineered so that virtually infinite customization combination can be created.
 
 
straight-in portafilter
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.
 
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 back flush during service.
 
drip prediction algorithm
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.
