straight-in portafilter improves efficiency and ergonomics

kb90

The ultimate workflow machine, a new standard in high volume café performance.

The KB90 is the ultimate evolution of the Linea PB form. Designed to optimize the workflow for the barista in the world’s busiest bars by improving the ergonomics and features of the machine. The KB90 is named for our Board Chairman, Kent Bakke. 20 years ago, Kent imagined one of the most exciting new features of the KB90, the Straight-in Portafilter. Kent has always seen La Marzocco’s mission to create machines that make the lives of the barista easier and more efficient, and the KB90 embodies this philosophy.
