All about the La Marzocco KB90 – Straight-in portafilter
On the KB90 the portafilter goes straight in: push it into the group without twisting, and release it with a button. La Marzocco built it for the busiest cafés, where baristas lock in hundreds of shots a day and wrists take the strain; according to La Marzocco the straight-in system cuts that strain twelvefold. After every shot, Steam Flush cleans the group with a burst of steam followed by hot water.
Which La Marzocco fits your needs?
The KB90 comes with 2 or 3 groups, as AV (programmable doses) or ABR (scales in the drip tray). High legs, a cup warmer and RAL colors are special-order options. Tell us your peak volume and how many baristas work the bar at once, and we help you choose.

Key features
Straight-in portafilter
Lock the portafilter in without twisting and release it with a button. Less wrist strain and a faster workflow, for left- and right-handed baristas.
Steam Flush
After each extraction a burst of steam from the group is followed by a hot water flush, keeping the group clean during the rush.
A coffee boiler per group
Each group has its own 1.3 liter saturated boiler. Dual PID controls coffee and steam boiler temperature.
AV or ABR
AV stops each shot at a programmed volume. ABR weighs the shot with scales in the drip tray and uses Drip Prediction to stop on target.
Pro Touch wands and half-turn steam valve
Steam wands that stay cool to the touch; the steam valve opens fully in half a turn and is serviced from the front.
Connected and monitored
La Marzocco Pro app, water sensor for conductivity and hardness of incoming water, USB port for firmware, eco mode and LED barista lights.

Reviews
La Marzocco KB90: our review
In the full review we look at how the straight-in portafilter and Steam Flush change the workflow in a high-volume café.
Frequently asked questions
Do my current portafilters fit?
No. The KB90 uses its own straight-in portafilters; the machine comes with them.
Which electrical connection does it need?
La Marzocco builds it for 200 V single phase, 220 V single or three phase and 380 V three phase, up to 5,670 W (2 groups) or 7,790 W (3 groups). Have your electrician check the connection before installation.
What does Steam Flush do?
After each shot, steam and then hot water flush the group and shower screen, so less coffee residue builds up during service.
AV or ABR?
AV stops the shot at a programmed volume. ABR has scales in the drip tray and stops on weight; useful when several baristas work the bar.
Which sizes can I order on this page?
This page lists the KB90 with 2 or 3 groups. Options such as legs, color, scales (ABR) or another voltage go through a quote.
What does OR include with the machine?
12 kg of OR specialty coffee for espresso, a Full Barista Training for two people from your team at OR Academy, and full installation of the machine with OR coffee beans.
