La Marzocco KB90 Commercial Espresso Coffee Machine
Ultimate workflow. Built for high-volume coffee service.
The La Marzocco KB90 is a high-performance commercial espresso machine designed around one simple idea: making great coffee faster, cleaner and easier.
Created specifically for busy cafés and high-volume coffee environments, the KB90 combines La Marzocco’s proven dual-boiler technology with its innovative Straight-In Portafilter, automatic Steam Flush, independent saturated boilers and advanced extraction technology.
The result is a commercial espresso machine that puts workflow, consistency and barista comfort at the heart of every service.
Available in 2, 3 group configurations, the KB90 is built to handle demanding coffee service while giving baristas precise control over every extraction.
Why choose the La Marzocco KB90?
The KB90 takes the familiar foundations of La Marzocco’s commercial espresso machines and rethinks how a barista interacts with them.
Its revolutionary Straight-In Portafilter removes the traditional twisting motion used to lock a portafilter into the group head. Instead, the portafilter engages with a straight-in movement, helping to create a more natural workflow and reducing repetitive wrist movement.
For busy cafés, that means less wasted movement and a smoother workflow during the morning rush.
The KB90 also features Steam Flush, automatically cleaning the group after extraction with a burst of steam followed by hot water. This helps minimise coffee residue and keeps the group cleaner during busy periods.
For cafés where consistency, speed and barista ergonomics matter, the KB90 is engineered to make every part of the coffee-making process work harder.
Straight-In Portafilter
A completely different way to work.
The standout feature of the KB90 is its Straight-In Portafilter system.
Rather than twisting the portafilter into the group head, the barista simply inserts it straight into position. La Marzocco designed the system to simplify the movement required to engage the portafilter and states that it can reduce wrist strain by 12 times compared with a conventional locking motion.
That makes the KB90 particularly suited to busy, high-volume coffee environments where baristas repeat the same movements hundreds of times during a shift.
It’s a small change that can make a big difference to the way a café works.
Steam Flush
Cleaner groups. Less interruption. Better workflow.
During a busy service, keeping espresso groups clean can be challenging.
The KB90’s automatic Steam Flush helps solve this by using a burst of steam followed by a flush of hot water after extraction.
This helps remove coffee residue from the group and reduces the build-up of unwanted flavours during service.
The result is a cleaner brewing system and a more efficient workflow, without relying on the barista to manually clean the group after every extraction.
Dual Boiler Technology
The KB90 uses a dual-boiler system, separating espresso brewing from steam production.
This allows the machine to maintain the conditions required for consistent espresso extraction while providing the steam power needed for busy milk-based coffee service.
Each group also has its own independent saturated coffee boiler, helping provide excellent temperature stability and allowing individual groups to be optimised for different coffees.
This makes the KB90 particularly useful for cafés serving multiple blends, single origins or decaffeinated coffee.
Dual PID Temperature Control
The KB90 features Dual PID temperature control, allowing the coffee and steam boiler temperatures to be electronically controlled.
Precise temperature management is fundamental to repeatable espresso, particularly when a machine is being used continuously throughout a busy service.
Combined with independent saturated boilers, the KB90 is designed to deliver stable brewing temperatures shot after shot.
ABR & Drip Prediction
For cafés looking for additional automation and consistency, the ABR configuration incorporates precision scales into the drip tray.
La Marzocco’s Drip Prediction technology uses the measured output from the espresso to predict the final yield and automatically stop the extraction at the desired point.
This helps baristas achieve greater consistency when switching between different coffees, blends and recipes.
For high-volume cafés, it can help reduce variation between shots while making the machine easier to use across different baristas.
Pro Touch Steam Wands
The KB90 is fitted with Pro Touch steam wands, designed to provide high-performance milk steaming while remaining cool to the touch.
The ergonomic design helps make steaming milk comfortable during busy periods, while the steam valves open fully with just a half turn, reducing the amount of movement required by the barista.
Independent Saturated Boilers
Each group head has its own saturated coffee boiler.
This allows different groups to be configured for different temperature requirements, providing flexibility for cafés working with multiple coffees.
Combined with La Marzocco’s temperature control technology, the system is designed to provide excellent thermal stability throughout service.
Designed for High-Volume Cafés
The KB90 was specifically developed for demanding commercial environments.
With configurations available from 2 through to 3 groups, the machine can be specified according to the volume and workflow requirements of the business.
Whether you’re running a busy independent café, speciality coffee shop, hotel, restaurant, bakery or high-volume hospitality operation, the KB90 is designed to keep up.
Built for Baristas
Good coffee starts with good equipment, but great equipment should also make a barista’s job easier.
The KB90 incorporates a number of features designed around the person operating the machine, including:
- Straight-In Portafilter system
- Pro Touch steam wands
- Half-turn steam valves
- Integrated barista lighting
- Digital display
- Intuitive programming
- Automatic Steam Flush
- Eco Mode
- Easy-access steam valve servicing
- Hot water economiser
Every element has been designed to make commercial espresso preparation more efficient.
Easy Maintenance
The KB90 is based on the proven architecture of the La Marzocco Linea PB, meaning many of its components and systems are familiar to technicians already experienced with La Marzocco commercial equipment.
The steam valve has also been engineered for straightforward servicing from the front of the machine, helping reduce maintenance time and potential downtime.
For a busy café, that’s an important consideration.
Energy Efficiency
The KB90 features insulated boilers and an Eco Mode that can be programmed to place the machine into standby mode.
Insulated boilers help reduce energy consumption while also contributing to temperature stability.
For businesses operating commercial coffee machines for long periods every day, energy efficiency can form an important part of the overall cost of ownership.
