The La Marzocco KB90 Commercial Espresso Machine: A New Standard for Specialty Coffee Shops

The La Marzocco KB90 is an uncompromising flagship designed specifically for extremely high-volume cafes. Serving as the ultimate technological evolution of the renowned Linea PB form, this model sets a new standard for performance and completely redefines bar ergonomics. The machine’s exterior design is inspired by the shield lines of the company’s classic logo, while the body panels are engineered to offer owners virtually endless customization possibilities.

Game-Changing Innovations

La Marzocco engineers have integrated revolutionary solutions into the KB90 that not only speed up beverage service but also significantly reduce the physical strain on baristas:

Straight-in Portafilter: This unique design allows the barista to insert the portafilter into the brew group with a simple, straight-in motion, eliminating the traditional side twist. This drastically reduces wrist strain and shaves precious seconds off every espresso shot.
Steam Flush: Immediately after extraction, the machine automatically purges the brew path with a burst of steam followed by a flush of hot water. This feature minimizes coffee residue buildup and maintains pristine group hygiene even during peak rushes.
Drip Prediction Algorithm: An intelligent algorithm accurately predicts the flow rate and stops the extraction exactly when the target cup volume or weight (when paired with optional ABR scales) is reached.

Technical Specifications and Performance

The machine is available to order in 2 and 3-group configurations, offering an unparalleled level of thermal stability:

Independent Boilers: The KB90 is equipped with an independent 1.3-liter coffee boiler for each individual group. This allows you to precisely set different brewing temperatures for multiple coffee beans simultaneously.
High-Capacity Steam: A 7-liter steam boiler (for 2-group) or an expanded 11-liter boiler (for 3-group) ensures a powerful, uninterrupted steam flow. The steam wands feature Pro Touch technology, remaining cool to the touch during milk texturing.
Dual PID and Saturated Groups: Electronic temperature control and specialized water circulation guarantee the absolute stability of every espresso pulled.

By choosing to buy the La Marzocco KB90, you are investing in a cutting-edge workstation that unites centuries-old Italian craftsmanship with the most innovative technologies of the 21st century.
