Varia VS4 - Precision Coffee Grinder with Conical Burr - Sand

Yes. The VS4 is designed specifically for single-dose grinding, with a hopper capacity of 30–40 g. This ensures maximum freshness, accuracy, and extremely low retention. The workflow encourages dosing beans before each grind for the best results.

The VS4 is capable of grinding from Turkish/espresso fine (100–200 microns) all the way to coarse French press (1000+ microns). The full adjustment range is approximately 2.5 revolutions from zero to fully open, providing excellent versatility for espresso, moka pot, pour-over, drip, AeroPress, French press, and cold brew.

The grinder uses a stepless 10-micron internal adjustment system.

Turn clockwise for finer grind.

Turn anticlockwise for coarser grind.

The adjustment scale is marked from fine to coarse, and the factory calibration aligns “0” with the burr touch point (do not grind at “0”).

The VS4 is powered by a 200 W brushless DC motor with a planetary gearbox. The motor speed is adjustable between 150–300 RPM, allowing control over heat, clarity, and grind uniformity during operation.

Set your desired RPM using the control dial on the side of the grinder.

Espresso typically benefits from lower RPM (e.g., 150–180).

Filter coffee may use higher RPM (e.g., 250–300).

Press the power button to begin; the burrs will start rotating immediately at your selected speed.

After grinding, once the burrs have stopped, press the single-dose bellows to blow out any remaining grounds from the grinding chamber. This helps ensure the VS4’s ultra-low retention performance and a cleaner workflow.

The VS4 features a tool-free quick-release chamber and hopper collar for easy cleaning.

You can choose between:

- Surface Clean (quick brushing of the burr chamber)

- Full Chamber Removal (removing the lower chamber for deep cleaning)

- Complete Disassembly (removing the outer burr, mounting plate, gaskets, and carrier ring—recommended only when needed)

The manual provides step-by-step instructions for each level of cleaning (Section 6).

Light maintenance such as brushing or using the bellows should be done after every grinding session.

A more thorough chamber clean is recommended weekly for regular users, and full disassembly is only necessary if you suspect clogging, oil buildup, or if you are replacing burrs.

To determine the burr touch point:

- Ensure the grinder is off and unplugged.

- Remove beans from the hopper.

- Turn the adjustment collar slowly clockwise while listening and feeling for the first point of contact.

- Stop immediately when you hear a faint “chirp” or feel resistance. This is your burr zero reference.

No. The VS4’s design isolates the calibration thread from the hopper thread. This prevents drift, cross-threading, and eliminates the need to recalibrate when removing the hopper for cleaning.

The VS4 includes a built-in thermal protection system.

If the motor or driver becomes too hot:

- The grinder may pause automatically after approximately 20 seconds of no coffee being detected in the grinding chamber.

- Allow the grinder to rest before restarting.

You can grind extremely fine, but never grind at the “0” burr touch point, as this can cause burr damage. Use caution when grinding near the finest end of the scale, especially for Turkish-fine settings.

The body is constructed from precision-machined aluminum alloy with stainless-steel components, ensuring stability, reduced vibration, and long-term durability.

Dimensions: 161.4 × 97.7 × 337 mm

Weight: approx. 5.27 kg

The stable, compact footprint makes it ideal for home and professional environments.

Check for:

- A clogged chute (clean with the brush)

- Incorrect grind setting (too fine for the beans)

- Beans stuck in the hopper (shake gently or remove lid)

- If the problem persists, follow the troubleshooting and maintenance steps in Section 6.

Yes, but with caution. Flavored or extremely oily beans may create buildup faster, requiring more frequent cleaning to maintain performance and prevent clogging.
