Swiss coffee grinder maker Pinecone recently launched the Siberian, a relatively compact production grinder for commercial settings.
The grinder’s breakthrough features include a brushless DC motor designed to maintain cool operation while also being compatible with single-phase 110-volt power, as well as adjustable burr speed.
The Siberian’s design was derived largely from its predecessor, the Foxtail, which has an identical countertop footprint. Both models feature the same 120-millimeter flat burrs, and their grind chamber modules are interchangeable.
Yet whereas the Foxtail requires 3-phase power to spin its burrs at 1,600 RPM — on United States power grids — the Siberian, which comes set by the factory to spin at 1,500 RPM, can run on standard household power.
“The conventional electric power connection brings high performance grinding to markets which could never have dreamed of it before,” Pinecone Founder Ilan Maimon told Daily Coffee News. “Developing a modern drive system and replacing the 3-phase conventional motor [also] achieves smaller height, cooler grinding on a much wider performance duty cycle, and an environmentally friendly ‘green’ grinder with much better energy efficiencies.”

The Siberian also introduces a digital grind chamber module featuring electronic grind adjustments executed by a servo motor. Changes to the grind setting are more precise than by direct manual adjustment, according to the company, and the system’s onboard memory can store and replicate precise settings. A self-homing and automated recalibration procedure is also built into the new modules.
“It’s a sophisticated ‘closed loop’ control system, which is monitoring the grind setting movements to a much finer resolution than 2 microns. The measuring resolution of our system is 0.3 microns, yet for convenience and user-friendly purposes, we limited the user [grind setting] resolution into 2 microns,” said Maimon. “Bringing a micron resolution accuracy, with absolute repeatability, is so important for brewers.”
Featuring an intuitive graphical interface, the digital module is also now available on the Siberian’s predecessor, the Pinecone. Data collection and new control features are expected to soon be available to users of the two grinders through an upcoming app.
Pinecone made its worldwide debut in 2023, launching its Foxtail commercial grinder and Pinion consumer grinder at the SCA Expo in Boston. The Siberian debuted one year later at the SCA Expo in Chicago and the Hotelex expo in Shanghai, China.
Priced at 5,600CHF ($6,249.10 as of this writing), Siberians that run on 220-volt power started shipping to international customers last month. Pending safety certifications, the company expects to begin shipping 110-volt Siberians to U.S. customers by September of this year. North Carolina-based GH Grinding & Brewing Solutions is Pinecone’s U.S. distribution partner.
