Precision Grinding for Every Brew: The VS3 Grinder is engineered for coffee enthusiasts who demand excellence in every cup. With its high-quality materials, advanced grinding mechanics, and user-friendly design, the VS3 delivers consistent, precise results for both espresso and filter brewing.
Cutting-Edge Grinding Performance: At the heart of the VS3 is a 48mm conical burr set, featuring a 6-core design with a 38mm inner diameter. Crafted from high-nitrogen 420 stainless steel, the burrs achieve a hardness of HRC58, providing durability and a burr life of up to 150kg of coffee. This ensures a consistent grind over time, with precise particle distribution for a better brew.
Stepless Adjustment for Unmatched Precision: The VS3 offers stepless grind adjustment, allowing for micro-level tweaks with a relative vertical burr shift of just 10 microns (0.01mm) per increment. This flexibility ensures that you can dial in your grind size with precision, whether you're pulling shots of espresso or brewing a perfect pour-over.
Efficient, Quiet, and Consistent: Equipped with a powerful 100W DC motor, the VS3 grinds with a load speed of 170 RPM and uses a stainless steel gearbox for smooth, consistent operation. An 18g dose can be ground in 34 seconds for espresso at the #4 setting, or in 25 seconds for filter coffee at the #10 setting. Despite its speed, the grinder operates quietly, allowing you to enjoy the process without noise disturbance.
Minimal Retention, Maximum Flavour: Designed for low retention, the VS3 ensures that your coffee stays fresh with every grind. With the use of RDT (Ross Droplet Technique), retention is less than 0.1g for a 10g dose, while without RDT it remains below 0.2g, keeping your grounds as fresh and uniform as possible.
Built to Last: The VS3’s body is constructed from ADC12 die-cast and machined aluminum, providing strength, durability, and stability for daily use. This solid construction, combined with its robust motor and stainless steel burr set, ensures the grinder can handle even the most demanding brewing needs.
Important Note for Light Roasts: While the VS3 excels at grinding for both espresso and filter coffee, please exercise caution when using it for underdeveloped light-roasted beans at espresso settings. These beans can be challenging to grind, so be sure to feed them slowly or adjust to a slightly coarser grind size to protect the burrs.
ZERO RETENTION FOCUS
76.5° SLOPED GEOMETRY
• The VS3 (Stepless 38mm) Electric Grinder utilises a sloped geometry with a 76.5° acute angle. Using this geometry also allows for ideal zero retention conditions as well as a better workflow in relation to adding coffee to the hopper, making grind adjustments, and 180° access to the dosing cup.
• Purging will not be necessary when grinding different coffees with a retention of less than 0.1 over a 10g dose.
SPACE GRADE CNC MACHINED ALUMINIUM CONSTRUCTION
ABSOLUTE PRECISION AND ALIGNMENT FROM THE GROUND UP
• Every edge of the main body is machined to 0.02mm accuracy and high grade processing.
• High grade scratch resistant spray powder coated matte finish. Durable and easy to clean.
PRECISION STEPLESS GRIND ADJUSTMENTS
FINE PITCHED THREAD WITH 0.01MM (10MICRONS) OF RELATIVE BURR SHIFT PER INCREMENT.
• Our stepless adjustment is operated by turning the hopper in the desired direction. As a result of our stepless assembly, we can achieve virtually endless particle sizes giving you full access to experimenting with your brews.
• Each shift of the burr represents a 10μm (Micron) relative vertical burr shift or 0.01mm per increment.
• Hopper capacity of 30g.
2ND GENERATION MOTOR
STAINLESS STEEL GEARBOX
• New motor construction with full stainless steel gearbox construction and 170RPM grind speed ensuring speed for espresso and filter settings.
• Uncompromised consistency and precision across all grind settings.
• Safety mechanism built in to ensure over torque protection.
UPDATED ASSEMBLY FOR INCREASED CONSISTENCY
SINGLE BODY OUTER BURR
• Improved burr chamber assembly for ultimate alignment and concentricity of the driveshaft and burr set resulting in extreme consistency and precision.
• Unique to the VS3 the driveshaft is machined to a 0.015mm tolerance.
• P5 class double layer ball bearings for smooth, stable and precise movements.
• Hard chamber premium springs for stability an damping of the burr under resistance load resulting in decreased vibrations and movements of the internal parts increasing consistency.
SMALL FOOTPRINT BUT MIGHTY
• Compact size and unmatched performance & consistency.
• VS3 is a highly compact electric grinder that has extreme performance from commercial espresso settings to hand drip and cold brew.
SINGLE BODY MACHINED OUTER BURR
• New outer burr design machined out of one piece of stainless steel using precision tolerances resulting in precise alignment, concentricity and stability while grinding resulting in a far more precise and consistent particle distribution.
• Small notches have also been added to the ears of the outer burr to ensure that it can be easily removed from the chamber by hand.
REFINED USER EXPERIENCE
• Magnets into our hopper lid to connect with the hopper as well as our base to connect with our dosing cup.
• Non slip silicone feet are also installed on the base of the VS3.
• Includes silicone bellows cleaner.
COMPACT DC WALL MOUNTED ADAPTER
• Discreet and compact, the power brick mounts directly to your wall or under cabinetry, keeping your bench space clean and clutter-free.
• Tuned specifically for the VS3’s motor requirements, the adapter provides steady DC current that supports smooth, low-RPM grinding with high torque output.
• Compatible with international AC standards (100–240V input), ideal for both home and commercial environments.
• Industrial-grade casing with integrated strain relief for long-term durability.
