La Marzocco KB90 Commercial Espresso Machine

About La Marzocco

La Marzocco was founded in Florence in 1927, and by 1939 had developed and patented the first coffee machine with a horizontal boiler — a design that became the industry standard. The KB90 represents the brand's most recent rethink of what a high-volume commercial machine should feel like from the barista's side of the bar.

The Product

The KB90 is the ultimate evolution of the Linea PB form, engineered specifically to optimise workflow for baristas working in the world's busiest bars. Its standout feature is the Straight-In Portafilter — the first of its kind in the industry — designed to simplify the motion of engaging the portafilter and reduce repetitive strain on the barista by a factor of 12. In a high-volume environment where a barista might pull hundreds of shots a shift, that's a genuine injury-prevention feature, not just an ergonomic nicety.

Beyond the portafilter redesign, the KB90 introduces Auto Steam Flush — a burst of steam and hot water after every extraction that keeps the group clean through the busiest hours and cuts down how often your baristas need to manually backflush. Auto Brew Ratio with Drip Prediction uses precision scales built into the drip tray to stop extraction based on mass rather than time, using an algorithm to improve shot accuracy and make dialling in genuinely easier. Independent boilers for each group head let baristas optimise temperature per coffee, rather than accepting one compromise setting across the whole bar.

About the Product Line: KB90 vs Linea PB

The KB90 builds directly on the Linea PB platform that's become an industry standard in its own right. Where the Linea PB gives you La Marzocco's proven saturated-group performance, the KB90 adds the Straight-In Portafilter, Auto Steam Flush, and optional Drip Prediction on top — the choice for the highest-volume bars where barista ergonomics and workflow speed are as important as the coffee itself.

Key Features

Straight-In Portafilter — The industry's first, reducing barista strain by 12 times over a traditional twist-and-lock motion.

Auto Steam Flush — Automatic post-extraction cleaning cycle that reduces manual backflushing during service.

Auto Brew Ratio with Drip Prediction (optional) — Precision drip-tray scales stop extraction by weight for more accurate, repeatable yield.

Independent insulated boilers per group — Optimise temperature for individual coffees rather than one setting for the whole bar.

Water pre-heating system — Reduces recovery and start-up time during peak service.

Choosing Between Versions

The KB90 is available in 2 Group and 3 Group configurations, each in AV (Automatic) or ABR (Auto Brew Ratio, with drip-tray scales) control. Choose the 3 Group for genuine peak-hour, multi-barista volume; choose ABR if you want extraction stopped by weight rather than fixed volume for the most accurate, repeatable yield.

Why Choose This Product

The KB90 is for the high-volume bar where barista wellbeing and workflow speed are treated as seriously as extraction quality — the kind of operation pulling shots continuously for hours at a time. If repetitive strain and workflow bottlenecks are genuine concerns at your busiest bar, this is engineered specifically to address both.

Buying and Installation Notes

Confirm your available phase and voltage supply before ordering — the 3 Group requires a heavier draw, so check your circuit capacity. Given its weight and commercial duty cycle, plan for direct plumbing into your water and drain lines. Optional extras include high legs (R7,199), a water sensor (R11,311), custom colour (R32,599), and an electric cup warmer (R11,499) — ask us about customisation.
