Experience Precision Grinding Like Never Before 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. 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 and 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.
