La Marzocco KB90

Overview

The La Marzocco KB90 is a commercial espresso machine that has found its way into the homes of the most dedicated and well-heeled espresso enthusiasts. Originally designed for high-volume specialty coffee shops, the KB90 introduced the revolutionary Straight-In portafilter system — an ergonomic innovation that allows baristas to insert the portafilter straight into the group head rather than twisting it in. This dramatically reduces repetitive strain during busy service. The dual boiler system with saturated group heads ensures unwavering thermal stability across all groups. The ABR (Auto Brew Ratio) system uses a scale integrated into the drip tray to measure output weight in real time, automatically stopping the shot at the programmed ratio. The KB90 features independent PID control for each group, a massive steam system, and the build quality that has made La Marzocco the most trusted name in specialty coffee. For home use, this machine is extreme overkill — but for those who want the absolute best commercial technology available, regardless of price, the KB90 delivers an unmatched experience.

The La Marzocco KB90 comes equipped with PID temperature control for precise brewing, pre-infusion for even extraction. It features a dual boiler boiler system made of stainless steel with a 350 ml capacity. The rotary pump delivers 9.0 bars of pressure for optimal extraction.

Priced at $18,000, the La Marzocco KB90 is designed for passionate enthusiasts and semi-commercial users who accept nothing but the best. The dual boiler design allows simultaneous brewing and steaming, making it ideal for milk-based drinks without any wait time.

In terms of build quality, the La Marzocco KB90 is a substantial machine, weighing in at 55.0 kg, manufactured in Italy, drawing 4500W of power. With dimensions of 500 x 600 x 450 mm (W×D×H), make sure you have adequate counter space. This machine requires direct plumbing, which provides unlimited water supply but needs professional installation.
