LINEA PB - a La Marzocco classic, re-imagined
In crafting the Linea PB, Piero Bambi refined and sharpened design elements and fine-tuned performance features that made the Linea Classic a specialty coffee icon. The Linea PB, designed by and named in recognition of Piero Bambi, introduces a new level of performance, reliability, and craftsmanship that carries the Linea into the future in a manner that is familiar, yet also fresh and new. The Linea PB features the iconic La Marzocco polished stainless steel body, updated with simplified lines and a lower profile, equipped with exclusive, user friendly interface software that gives the barista direct functional control over boiler temperature, brewing volume, hot water tap dose, auto-back flush as well as other options.
The new conical mechanical paddle is inspired by the original mechanical group used on the La Marzocco GS – the first dual-boiler espresso machine with saturated groups (1970). This conical valve system assures progressive control of water flow and pressure via an internal orifice, before applying full pressure. The new conical paddle valve controls the pre-infusion while the volumetric pump is working at full pressure, therefore barista may also perform a pre-infusion on one group while the other is extracting coffee. This dynamic system allows the barista to reduce channeling for a more balanced extraction.
