La Marzocco KB90
Built for Cafes
Built for the World's Busiest Bars
Named for La Marzocco's board chairman, Kent Bakke, the KB90 is the ultimate evolution of the Linea PB form, built specifically for the highest-volume cafes in which every second and every motion behind the bar matters. Rather than starting from scratch, La Marzocco built the KB90 on the trusted, tested components of the bestselling Linea PB, then redesigned the parts of the workflow that create the most strain and the most friction during a high-volume rush.
Straight-In Portafilter
Locks into place on rails, cutting the twisting motion that drives barista wrist.
Automatic Steam Flush
Purges the brew path after every extraction, keeping groups clean through the rush.
Pro Touch Steam Wands
Vacuum-insulated wands that stay cool to the touch even after the busiest rush.
Authorized Dealer
Official La Marzocco authorized dealer. Full warranty support included.

The Machine
The Ultimate Workflow Machine for High-Volume Cafes
The headline change is a completely reengineered straight-in portafilter that locks into place on rails and releases with a press of the thumb, cutting the twisting motion that drives repetitive-stress injuries like barista wrist by roughly 12 times compared to a traditional portafilter engagement. Paired with an automatic steam-flush cycle after every extraction, the KB90 is built to keep baristas moving and groups clean throughout the day's busiest service.
The KB90 shares its dual-boiler architecture, saturated groups, and PID temperature control with the Linea PB, so servicing it doesn't require a technician to stock a new inventory of parts. What sets the KB90 apart is everything built around speed of service: the straight-in portafilter, the automatic steam flush, and a Drip Prediction algorithm that uses precision scales built into the drip tray to stop extraction based on mass instead of a fixed volume, improving shot accuracy and making dial-in easier across a team of baristas. See the full specifications on La Marzocco's official KB90 page ↗.
The KB90's back panels have also been engineered for broad customization, making it one of La Marzocco's most visually flexible machines for cafes and roasteries that want a KB90 finished to match a specific brand identity.
"A new standard in high-volume cafe performance, built to make great espresso faster, cleaner, and easier."

Sizing & Configuration
Choosing the Right Group Count and Configuration
If you are unsure which configuration fits your projected daily cup count, Bean and Brew Technologies can walk through your layout and volume expectations and recommend the right group count before you order.
| Group Count | Best For |
|---|---|
| 2 Group | Suits high-volume independent cafes and busy single locations where two baristas working the bar need a workflow advantage during peak hours. |
| 3 Group | Built for the highest-volume cafes, flagship locations, and multi-barista bars where speed of service is the top priority. |
AV or ABR: Which Configuration Fits Your Bar
Like the Linea PB, the KB90 is not offered in a semi-automatic (EE) version. Every KB90 is Auto-Volumetric, and the real decision is whether to add integrated drip tray scales for Auto Brew Ratio and Drip Prediction dosing.
Choose Standard AV If…
Your team is comfortable dialing in and reprogramming volumetric dose buttons and you want the most direct version of the platform.
Choose ABR If…
You want the machine to dose by weight or brew ratio, and want the Drip Prediction algorithm helping every barista on your team dial in shots consistently.
Comparison
KB90 vs Linea PB: How to Decide
The KB90 and the Linea PB share the same dual-boiler architecture, saturated groups, and PID temperature control. The KB90 is built directly on trusted Linea PB components, so choosing between them comes down to workflow priorities rather than shot quality.
The Linea PB is available in 2, 3, or 4 group configurations, offers a lower up-front cost, and is the more common choice for independent cafes and growing multi-unit operators. The KB90 is available in 2 or 3 group configurations and adds the straight-in portafilter, automatic steam flush, and Pro Touch steam wands, all engineered specifically to reduce barista strain and speed up service in the busiest, highest-volume environments. For cafes doing hundreds of drinks a day, in which every motion behind the bar counts, the KB90 is the stronger fit. For cafes that want Linea-platform reliability without the workflow-specific upgrades, the Linea PB remains an excellent choice with a lower cost of ownership. Either way, both machines are backed by the same Bean and Brew Technologies installation, warranty, and factory-trained service team.
