The La Marzocco Linea PB is the machine that defines the modern specialty coffee bar. An evolution of the legendary Linea that shaped café espresso culture for decades, the Linea PB adds independent brew boiler PID control to each group, built-in scales as an optional upgrade, and connectivity features that make it as technologically sophisticated as it is mechanically proven. This is the machine that runs some of the most acclaimed espresso bars in the world.
At Kanen Coffee, the Linea PB serves as our flagship showroom demonstration machine — the benchmark against which everything else is measured. Its saturated group heads, dual-boiler thermal stability, and consistency across groups make it the choice for high-volume specialty cafés, but its size and capability also make it a coveted home installation for the most serious espresso enthusiasts. There's nothing quite like pulling a shot on a Linea PB.

What It Pairs Well With
The Linea PB is a commercial machine and ideally pairs with commercial-grade grinders — the Mazzer Major, Mahlkönig E65W GbS, and Nuova Simonelli Mythos are the most common pairing in commercial settings.
For a home or low-volume installation, the showroom grinders below can work:
-
Eureka Atom 75 — our highest-performance showroom grinder; 75mm flat burrs and stepless adjustment hold up well for low-volume use
-
Lelit William — capable flat-burr option for home Linea PB installations
Our team can advise on commercial grinder options if you're setting up a café — book an appointment to discuss.
