La Marzocco KB90 Espresso Machine - 13.6L Boiler Capacity, Dual PID
The La Marzocco KB90 sets a new benchmark for high-volume café performance, engineered specifically to make crafting exceptional espresso faster, cleaner, and more efficient. Representing the ultimate evolution of the iconic Linea PB form, this machine dramatically optimises barista workflow while significantly reducing physical strain. Its revolutionary 'Straight In' portafilter system eliminates the traditional twisting motion, easing the physical repetitive strain on the barista’s wrist and accelerating speed of service during peak rush hours.
To maintain pristine operating conditions without disrupting service, the KB90 features an automated Steam Flush function that delivers a burst of steam and hot water after every extraction, rapidly removing coffee residue and preventing off-flavoured buildup. Precision is further elevated by an advanced drip prediction algorithm, which automatically terminates the extraction at the perfect moment to ensure precise cup yields, even when seamlessly switching between different single origins, blends, or decaf options. Additionally, the machine offers an unprecedented level of aesthetic expression, with outer panels engineered to allow virtually infinite customisation combinations.

Features

Straight-In Portafilter: A revolutionary layout that allows the barista to insert the portafilter directly from the front, completely removing the traditional twist-and-lock wrist movement to significantly lower repetitive physical fatigue.

Auto Steam Flush: Automatically shoots a burst of steam and a hot water rinse immediately following an extraction, purging coffee residue to reduce back-flushing down-time during service rushes.

Dual Boiler System & Saturated Groups: Incorporates distinct boilers to isolate espresso brewing from high-capacity steam output while maintaining robust temperature consistency shot-after-shot.

Independent Brew Boilers: Every individual group head houses its own micro-boiler, letting baristas optimize precise extraction temperatures for different origins and custom blends simultaneously.

Dual PID Temperature Control: Enables digital adjustment over temperatures for both the brew and steam boilers.

Auto Brew Ratio (ABR) & Drip Prediction: Premium option equipping the drip tray with built-in precision scales that work alongside an internal predictive algorithm to automatically kill the extraction exactly on target mass.

Pro Touch Steam Wands: High-performance steam arms engineered with vacuum insulation to remain totally cool to the touch for barista safety.

Front-Accessible Steam Valve: Redesigned setup allows technicians to service or rebuild the steam assembly from the front face without removing the valve housing from the machine.

Hot Water Economizer: Provides full control to adjust tap water temperature limits for clean rinsing and tea prep.

Infinite Aesthetic Customization: Structural paneling engineered to accept custom finishes, wraps, and colors for a personalized look.

Why the La Marzocco KB90 is the Smart Choice for Your Business
In a fast-paced specialty coffee market, a café's success rests on three fundamental pillars: speed of service, product consistency, and staff retention. As foot traffic scales, standard commercial espresso setups can inadvertently create operational bottlenecks and increase staff physical fatigue. The La Marzocco KB90 is specifically engineered as a high-volume solution to these challenges, turning the espresso bar from a bottleneck into a highly optimized profit driver.
Redefining Throughput and Protecting Your Staff
The most immediate business advantage of the KB90 is its revolutionary Straight-In Portafilter system. By removing the traditional twist-and-lock motion, it reduces physical strain on the barista's wrist by up to 12 times. In a busy environment, this ergonomics boost directly translates to faster shot preparation and significantly mitigates repetitive strain injuries among your team. Happy, pain-free baristas work faster, engage better with customers, and experience less turnover—saving your business substantial hiring and training costs.
Combined with the automated Steam Flush function, which purges coffee residue with a burst of steam and hot water after every shot, your team no longer wastes critical seconds manually wiping down screen elements during peak rush hours. The machine effectively keeps itself clean, allowing your baristas to focus entirely on maintaining throughput and driving sales.
Surgical Consistency That Drives Customer Loyalty
Speed means nothing if the beverage quality suffers under pressure. The KB90 protects your brand reputation with independent group boilers that isolate brewing temperatures perfectly, ensuring thermal stability shot-after-shot.
When equipped with the optional Auto Brew Ratio (ABR) and Drip Prediction technology, the machine automatically controls target mass in the cup using integrated precision scales. Human error is eliminated from the equation. Whether your staff is switching between a house blend, single-origin guest roast, or decaf, the KB90 precisely self-terminates the shot exactly when your recipe demands it. This guarantees that every customer receives the exact same premium beverage experience regardless of how busy the bar is, locking in the repeat customer base that sustains long-term business growth.
