La Marzocco KB90 AV 2-Group – Portafilter machine with Straight-In for high throughput
During rush hour, every movement counts. The KB90 is designed for throughput and workflow: the portafilter is no longer clamped in, but pushed straight into the brew group – "Straight-in Portafilter". This is faster and more ergonomic, shot after shot, shift after shift.
At Coffee Coaching Club, we are both a La Marzocco partner and a coffee roaster – 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 – ideal for high-volume operations. The Steam-Flush function automatically flushes the brew group with steam assistance – for more cleanliness between shots. Plus, multi-boiler technology, integrated scales, insulated Pro-Touch steam wands, and Drip Prediction. AV stands for Auto-Volumetric: programmable shot volumes per group.
Optionally, the KB90 is available with tall feet, which add 8 cm to the height – practical for large to-go cups.

Roaster's Tip
A machine with integrated scales and Drip Prediction only truly shines with consistent grind and beans. As a roastery, we supply freshly roasted beans for your business and advise on the appropriate grinder setup. Talk to us. This is our recommendation, one of many.
