The VS4 redefines your coffee ritual through the perfect balance of design precision and mechanical excellence.
Powered by a 200 W brushless motor with a planetary gearbox and variable RPM control (150–300 RPM), it delivers uncompromising consistency, torque, and control. At its core, a 53 mm 6-core conical burr set ensures exceptional uniformity and clarity in every grind — from espresso to cold brew, maintaining remarkable consistency throughout the grind range.
Key Features
SUPERIOR BURR DESIGN
Precision-engineered 53 mm 6-core conical burrs deliver optimal particle-size distribution and refined flavor clarity across all brew methods. The geometry and alignment are optimized for balanced extraction and clean flavor definition.
POWERFUL & EFFICIENT
Driven by a 200 W brushless motor paired with a planetary gearbox, the VS4 maintains stable torque and smooth performance across variable speeds (150–300 RPM), offering fine-tuned control for every grind profile.
LOW RETENTION DESIGN
A patented single-piece removable burr chamber with a quick-connection bayonet system ensures low retention and effortless maintenance. The design minimizes grind waste and allows fast, tool-free disassembly while maintaining perfect alignment.
ROBUST HOPPER ADJUSTMENT
A stepless 10-micron adjustment system provides ultra-fine control from espresso to cold brew, maintaining high consistency throughout the grind range. An independent internal adjustment thread eliminates hopper drift, cross-threading, and wear — ensuring smooth, repeatable, and precise calibration every time.
ACTIVE IONISATION TECHNOLOGY
Integrated active ionisation neutralizes static and preserves coffee aromatics, delivering a cleaner, more uniform grind with reduced clumping.

Why Should You Get This
| Tool-Free Quick Release | You can lift out the entire one-piece burr chamber and upper assembly in seconds without losing your calibrated zero point or grind setting. |
| Variable RPM Control | A powerful 200W brushless DC motor and planetary gearbox let you change speeds from 150 to 300 RPM. Lower speeds mimic hand grinders for delicate filter coffee, while higher speeds suit espresso. |
| Active Ionization | An integrated ionizer and plasma generator actively eliminate static electricity for a clean workflow with near-zero retention. |
| The Varia VS4 delivers serious grind performance in a compact form, with precise stepless adjustment, variable RPM, and low retention for effortless dialing-in from espresso to filter. | |
