Linea PB | 3 Group

List Price: $23,320

If you’ve visited a specialty coffee shop over the last 10 years, there’s a high likelihood that your espresso was brewed with a Linea PB. The Linea PB adds to the reliability of the Linea Classic S with significant feature enhancements designed to put the barista in the driver’s seat. And with the choice of volumetric or Auto Brew Ratio (ABR) technology, baristas can customize every aspect of extraction to benefit both the end cup and the behind-the-bar workflow.

The Linea PB machine is also available as the Linea PB X. While the Linea PB has one brew boiler that powers all group heads, the PB X features an independent brew boiler for each group head. This feature empowers baristas to tailor the temperature of each group head to match the recipe for a specific single-origin coffee, blend, or roast level that you might find at a coffee shop that prioritizes rare or exceptional quality coffee varietals.

Performs Best For

Mid to high-volume coffee shops that desire customizable barista controls (such as dedicated temperatures) to enhance espresso quality, aid in a smooth bar flow, and improve energy efficiency. 

Fresh Cup uses a scoring rubric to rate espresso machines on a variety of metrics. See our scoring rubric:

Program Sophistication Gauges how deep and precise a café’s espresso program can be on the machine, and how much barista training it demands. Level 1 covers capsule or batch-brew stations, while Level 5 delivers full pressure/flow profiling, integrated scales, data logging and IoT connectivity for competition-grade menus. Volume Capability Reflects the peak drinks-per-hour the machine can maintain without recovery issues. Scores run from under 30 drinks (Level 1, boutique bar) to 120+ drinks per hour (Level 5, drive-thru chains or stadium kiosks). Automation Support Measures how many routine tasks the machine handles on its own—dosing, flushing, milk steaming and self-cleaning. It spans fully manual levers (Level 1) up to bean-to-cup super-automatic sequences (Level 5). Extraction Control Rates the operator’s control over brewing variables. Entry levels lock in temperature and pump pressure; mid-levels add independent PIDs and programmable pre-infusion; Level 5 delivers full pressure/flow profiles with live data logging. Workflow & Ergonomics Assesses how the machine’s physical design speeds service and reduces fatigue. Higher scores denote low-profile bodies, cool-touch or auto-purge steam wands, intuitive UIs and other features that minimise repetitive strain. Tech & Connectivity Looks at the depth of digital features—from simple PID displays and shot timers (Level 2) up to Wi-Fi dashboards, cloud telemetry, open APIs and fleet-management suites (Level 5). Design Customization Captures how extensively the machine’s appearance and UI can be tailored. Level 1 models ship in a single finish; mid-range offers swappable colour panels or logo plates; Level 5 machines feature fully modular skins and deep UI-branding options.

Noteable Features

Digital Controls

In comparison to the older Linea Classic S, the Linea PB has digital controls that allow baristas to program everything from steam temperature to volumetric dosing with the push of a button.

Choose Your Configuration

Volumetric (AV) allows baristas set the desired output of the shot and the machine stops automatically based on the programmed pulses. Optional drip tray scales for Auto Brew Ratio (ABR) capabilities allows baristas to set a desired coffee: water ratio and the machine automatically pulls the shot to that ratio.

Piero Group Caps

To accomplish the proper volumetric dosing features, La Marzocco introduced Piero Group Caps with the Linea PB. These group heads have an integrated flow meter that ensures proper thermal stability and pulse accuracy in comparison to older Linea models.

Eco Mode

For energy-conscious cafe owners, the Linea PB also comes with Eco Mode. In Eco Mode, the machine enters a “standby” state which lowers boiler temperatures when not in use.
