La Marzocco KB90 3 Group
The 3-group KB90 is La Marzocco's high-throughput evolution of the Linea PB, designed around a straight-in portafilter that locks without the usual wrist twist and an automatic steam flush that cleans the group between shots. With an independent boiler per group and optional drip-prediction scales, it is built for the busiest cafés where speed and consistency matter most.
