La Marzocco KB90 Espresso Machine | 2 or 3 Groups
Denim Coffee
The KB90 is the ultimate evolution of the Linea PB form. Designed specifically to increase speed of service in the highest volume cafes while easier for the barista thanks to an improved workflow. La Marzocco has redesigned the portafilter system to improve workflow efficiency and to reduce the wrist strain of the user.
Efficiency can also be increased thanks to Steam Flush: after each extraction, a burst of steam from the grouphead is followed by a flush of hot water, keeping the machine clean even in the busiest rush hours.
This innovative function minimizes off flavored buildup, and increases the time between having to clean the group. The KB90 allows for a new level of expression in machine design, the panels have been engineered so that virtually infinite customization combination can be created.

Auto-Volumetric (AV) vs Auto Brew Ratio (ABR)
AV measures the volume of the water passing through the portafilter using a flow meter. Shots are stopped when a pre-set volume of water has been dispensed. This provides consistency based on water volume. Best for shops that prioritize ease of use and reliability for a large volume of shots.
ABR measures the weight of the liquid espresso using built-in scales. Shots are stopped when a target weight (or ratio) of liquid espresso has been achieved. This provides greater consistency by automatically adjusting for variations in the coffee dose weight. Best for quality-focused cafes that need maximum control and flavor consistency across different coffees.
