La Marzocco KB90 AV 2-Group – Espresso Machine with Straight-In Portafilter for High Throughput
During rush hour, every movement counts. The KB90 is built for throughput and workflow: the portafilter is no longer clamped in, but pushed straight into the brew group – “Straight-in Portafilter”. It's faster and more ergonomic, shot after shot, shift after shift. The 2-group version brings this same speed to a more compact footprint behind the counter – ideal for businesses that want high throughput without the larger footprint of a 3-group machine.
At Coffee Coaching Club, we are both a La Marzocco partner and a coffee roastery – we support configuration, installation, training, and service.
What makes the KB90 special
The KB90 is the further development of the Linea PB for maximum output. The Straight-In portafilter saves steps with every shot and protects the wrist. The Steam-Flush function automatically purges the brew group with a burst of steam and hot water after every shot – keeping things clean even during the busiest hours. It also brings multi-boiler technology with saturated brew groups and insulated Pro-Touch steam wands that stay cool even under continuous use. AV stands for Auto-Volumetric: programmable shot volumes per group, controlled by the water volume passing through.

Installation, delivery and service
The machine comes ex-factory without a plug. For on-site commissioning, we recommend the installation package and the descaling filter installation – both are automatically added to your cart as soon as you add the machine. Availability and delivery are arranged individually with you after purchase. A private barista course can be booked separately. Questions in advance via [email protected] or by phone during business hours; personal consultation in Bern and Zurich.
Who the KB90 2-Group is for
For cafés, roasteries with a bar, and hospitality businesses that want high throughput on two groups and a fast, ergonomic workflow – without needing the larger footprint of a 3-group machine. Our opinion is one of many: choosing between 2 and 3 groups usually comes down to expected guest volume and the space you have behind the counter.
