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. With every new coffee machine from CHF 1'500, a private barista introduction course of around 60 minutes is included – in Bern, Zurich or online, for up to two people from the same household or company attending together. The course must take place within one month of delivery; after that, the entitlement expires. 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.
What goes with it
