The KB90 is La Marzocco's Ultimate Workflow Machine.
Taking the Linea PB form to the next Level, the KB90 built keeping in mind Baristas in the world's busiest cafes.
The KB90 is named for La Marzocco Board Chairman, Kent Bakke who 20 years ago, Kent imagined one of the most exciting new features of the KB90, the Straight-in Portafilter.
dual boiler system
Separate boilers optimize espresso brewing and steam production.
independent brew boilers
Separate boilers for each group head allow barista to optimize temperature for individual coffees.
PID temperature controller
Allows you to electronically control coffee and steam boiler temperature.
saturated group design
Ensure unsurpassed thermal stability, shot after shot.
thermal stability system
Brew water is pre-heated before entering the boiler for increased temperature stability.
Keeps the group clean with an automatic burst of steam and a flush of hot water between extractions.
pro touch steam wands
High performing steam wands that are cool to the touch.
easy rebuild steam valve
Engineered so the valve can be serviced directly from the front of the machine without needing to be removed.
hot water economizer
Enables you to fine-tune the tap water temperature for rinsing.
Intuitive programming makes it easy to adjust machine parameters.
LED lighting allows you to focus on your extraction and the cup.
auto-volumetric and auto-volumetric with scales/Auto Brew Ratio (ABR)
Designed to simplify the motions required to engage the portafilter and reduce the strain by 12 times on the barista for even greater performance and everyday usability. High volume coffee environments demand that a barista can work fast and efficiently to produce drinks during busiest periods of the day. The Straight-In Portafilter can noticeably mitigate the repetitive stress injuries occurring through its ease of action improving the natural workflow and output of barista.
The Steam Flush automatically cleans the shower screen with a burst of steam and a flush of hot water through the grouphead after each extraction. Thanks to the use of hot steam the shower screen remains clean longer, compared to the use of hot water only, reducing the need of in-shift backflushing of the machine. The Group Steam Flush helps the busiest bars keeping the machine clean also in the busiest rush-hours minimizing the unpleasant flavor notes due to a dirty brew path. The steam flush function can also be set splitting the two separate functions: the group steam clean that consists in a spray of steam and a 3 second hot water auto-flush.
The Drip Prediction algorithm automatically stops espresso extraction at the correct moment to ensure target beverage mass is reached. Drip prediction works by monitoring the flow of espresso into the cup via load cell, with this data the algorithm is used to predict the exact moment the beverage needs to be stopped in order to reach the correct final weight without the need to set an offset time. Because this system is algorithm based, it does not need to learn over time, and will not lose accuracy if you switch between blends, decaf and single origins.
The iconic 3-button keypad has proven itself reliable, user-friendly and appreciated worldwide. In combination with proprietary La Marzocco electronics, programming is intuitive for both baristas and technicians.
Using the same hardware logic of the Linea PB, the programming of each function is easy and intuitive for all kind of users; from roasters to technicians, from baristas to bar owners.
The easy rebuild steam valve is a revolutionary mechanical steam valve that both baristas and technicians will love. It keeps the same standard of steam quality in steaming milk compared to all other La Marzocco machines appreciated from baristas around the world. The valve is also engineered in a way that, in case of ordinary or extra-ordinary maintenance, technicians can access the valve without the need of removing the body panels of the machine, minimizing the machine downtimes and the duration of servicing.
The La Marzocco Pro \u2013 Touch Steam Wand, ensures the steam wand is always cool to handle by the barista. Designed with state-of-the-art technology from the aerospace industry, the barista\u2019s hand is fully insulated from the hot steam.
