Elegant engineering with superior temperature control   Equipped with a CPU board and designed for superior temperature control, the gb5 combines gracious lines and harmonious curves with powerful technological advancements, in line with classic La Marzocco design and spirit. The machine is an understated companion to any coffee bar. Its unmatched temperature stability provide steady brew water and steam even at the peak of the morning rush. The gb5 has redefined the standard for temperature stability in modern espresso equipment in light of “PID” technology.   Features Saturated groups ensure unsurpassed thermal stability, shot after shot. Dual boiler system separate boilers optimize espresso brewing and steam production. Dual pid (coffee and steam) allows you to electronically control coffee and steam boiler temperature. Insulated boilers reduce energy consumption while contributing to temperature stability. Ruby flow restrictors synthetic ruby flow restrictors resist scale formation and erosion. Pre-heating system prior to entering into the coffee boiler, water is pre-heated – thus increasing productivity.   Product Brochure

Ultimate workflow   Easy The KB90 is tailored to the needs of the busiest coffee shops, making drip preparation easier for barista. Straight in portafilter The Straight In Portafilter is designed to simplify the motions required to engage the portafilter and reduce the strain 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. It has been proven in a study conducted by FAENTIA CONSULTING S.r.l. that the Straight In Portafilter can reduce strain on the barista by 12 Times / 1200%. The Straight In Portafilter offers workflow efficiency and a universal ease of use. Steam flush 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. Consistent In an aim to improve cafe workflow, advanced electronic features have been added to the KB90 in order to remove the excessive steps required to prepare drinks without compromising quality and consistency. Drip prediction algorithm 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. Familiar interface 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. Reliable The KB90 has been designed as an evolution of the Linea PB, featuring La Marzocco’s greatest technologies all in one. Linea PB logic 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. Easy rebuild steam valve 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. Pro-touch steam wand The La Marzocco Pro – 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’s hand is fully insulated from the hot steam.
