Varia VS4 Coffee Grinder

Precision Single-Dose Engineering

The Varia VS4 Coffee Grinder represents a significant leap forward in home brewing technology, offering a level of precision and consistency previously reserved for commercial environments. Designed for the dedicated home barista who demands exacting standards, this electric grinder combines advanced mechanical architecture with a user-friendly single-dose workflow. Whether you are dialling in a complex espresso or brewing a delicate pour-over, the VS4 provides the granular control necessary to unlock the full potential of your beans.

53mm Supernova Burr Technology

At the core of the Varia VS4 lies the precision-aligned 53mm 6-core stainless steel Supernova conical burr system. These burrs are engineered specifically for high-clarity extraction, producing a uniform particle distribution that enhances flavour separation. The geometry of the Supernova burrs reduces the production of fines, ensuring that your espresso shots remain balanced and your filter brews stay clean and distinct. The result is a cup profile that accurately reflects the roast and origin of the coffee, without the muddiness often associated with standard conical burrs.

Stepless Adjustment for Exacting Control

Achieving the perfect extraction requires minute adjustments, and the VS4 delivers with its stepless adjustment system. Offering 10-micron precision, this mechanism allows you to fine-tune your grind size with incredible accuracy. Unlike stepped grinders that force you to settle for a setting that is "close enough," the VS4 lets you find the exact point where flavour and texture align. The adjustment dial is smooth and stable, ensuring that once you have found your sweet spot, the setting remains locked in without drift.

Ultra-Low Retention Workflow

The Varia VS4 is built around a 76.5° sloped architecture, a design choice specifically implemented to optimise bean feed and minimise retention. By utilising a near-vertical exit path and integrated bellows, the grinder ensures that almost every gram of coffee you put in makes it into your dosing cup. This ultra-low retention design—often less than 0.1g—means you are always brewing with fresh grounds, eliminating the need to purge waste between grind size changes or different beans.

Powerful and Stable Motor Performance

Driving the system is a robust 200W brushless DC motor paired with a planetary gearbox. This combination provides high torque at lower speeds, maintaining RPM stability within ±1.5% even when grinding dense, light-roast beans at fine settings. The variable speed control (150–300 RPM) allows you to experiment with grind speeds to further manipulate the particle distribution and taste profile of your coffee.

Built for Versatility and Durability

Constructed from CNC-machined aluminium alloy and stainless steel, the VS4 is as durable as it is functional. Its modular design features a quick-connect chamber that allows for tool-free cleaning without losing your alignment or zero point. From the magnetic dosing cup to the electrostatic-reducing exit chute, every component has been considered to streamline your morning routine.
