The most important features of the La Marzocco Linea PB AV

The La Marzocco Linea PB AV espresso machine stands out for its sleek design, state-of-the-art features, and outstanding performance. It's the ultimate choice for coffee shops, restaurants, and specialty cafes aiming to elevate their espresso offerings.

Size and design
Crafted with La Marzocco's renowned polished stainless steel body, the Linea PB AV exudes a modern yet timeless charm. Its simplified lines and lower profile blend aesthetic appeal with practicality, seamlessly integrating into any space while providing ample workspace for baristas. Embracing more modern design elements compared to the Linea Classic S AV, such as the Piero group caps and sleeker lines, it offers a contemporary twist on the classic Linea design.

Efficient and easy to use
An easy to use digital display allows for efficient and user-friendly control over the machine’s many capabilities, providing real-time readings for coffee boiler temperature, group temperature, steam pressure, and more. Password protected USB firmware updates make this machine highly adaptable and keeps it at the edge of technology.

Precision with saturated groups
Equipped with saturated groups, the Linea PB AV guarantees thermal stability and precise temperature control with every espresso shot. This ensures consistent extraction, allowing you to deliver shots that are rich, aromatic, and bursting with flavor. Available in 2 configurations, you can choose between 2 or 3 groups, tailoring the machine to suit more specific needs and volume requirements. This machine is designed to fit seamlessly into any barista station while offering substantial capacity. These features, combined with Piero group caps that aid in thermal stability, supplement this machine's sturdiness while providing ample space to deliver an array of coffee options. 

The boiler for the coffee group heads is a single one. If you would like to have independent boilers for each group head, we advise you to have a look at the La Marzocco KB90. It is an upgrade of the La Marzocco Linea PB AV

Dual boiler
The machine stands tall with a dual boiler system, a feature that perfectly balances the temperature for both brewing and steaming at the same time. This offers exceptional control, allowing you to deliver a superbly balanced espresso shot every single time. The innovative Piero group caps (designed by Piero Bambi) and saturated groups ensure unsurpassed thermal stability for consistent shots.

The La Marzocco Linea PB AV doesn’t just stop at the dual boiler. What puts this machine on a pedestal is the PID (Proportional-Integral-Derivative) control, a system that provides a precise and consistent temperature, crucial for an outstanding brew. This level of control ensures your coffee is always served at its optimal temperature, elevating the flavor to the next level. 

The AV feature allows baristas to program the amount of time or volume an espresso shot receives. The machine automatically dispenses the desired amount of coffee

steam wand
The machine comes with a normal steam wand that makes perfectly good, velvety milk foam, but you will have to watch out not to scald your hands by touching it while steaming milk, or after.

Let's not forget about the ECO mode, an energy saver option that puts power conservation in your hands. It’s saving you money as well as being kind to the environment - a critical addition in our increasingly eco-conscious world. 

Auto backflush & ruby flow restrictors
The Linea PB AV also comes equipped with auto backflush and ruby flow restrictors. Auto backflush simplifies the cleaning process, thereby minimizing downtime and keeping the machine at its optimum performance. Ruby flow restrictors prevent the impairment due to scale buildup and maintain stability, taking the maintenance off your plate.

  • Superior espresso quality: The Linea PB is known for producing top-notch espresso quality that loyal La Marzocco fans love. With its advanced PID control and Ruby flow restrictors, brewing exceptional and consistent espressos is a breeze.

  • Durability and energy efficiency: The machine's reputation for durability is a significant advantage. Furthermore, its ECO mode takes it a notch higher, contributing to energy conservation.

Cons of the Linea PB AV: 

  • Learning curve: Despite being user-friendly, the advanced technology in Linea PB could be overwhelming to new baristas, with a steep learning curve to really make use of all its features.
  • Cost: As a premium espresso machine, the Linea PB comes with an elevated price tag. The high-quality technology and durability could be worth the investment for some, but it might be a barrier to others with a more limited budget.
  • Size: Its dimensions, although accommodating both a 2 or 3 group setup, could be cumbersome for smaller coffee shop spaces or home counters; accommodating it might require some planning.
