Mahlkönig VTA 6S grind settings
On the Mahlkönig VTA 6S, start pour over at 7, espresso at 3.5 and French press at 11.3. Every other method, with the range to adjust in, is below.
The shape of this dial
The top line is the universal grind index every BrewMark recipe uses. The bottom line is the VTA 6S’s own dial. The connectors show how one maps onto the other.
VTA 6S settings for each brew method
Start at the recommended setting, brew, then move within the range by taste. Sour or weak means go finer; bitter or harsh means go coarser.
| Method | Setting | Range |
|---|---|---|
| TurkishThe finest setting this dial has. Turkish wants powder, around 150 µm. | 1≈ 170 µm | fine end |
| EspressoFine. Aim for a 25–30s shot and adjust from there. | 3.5≈ 330 µm | 2.5 – 4.8 |
| Moka potFiner than filter, coarser than espresso. No tamping. | 5.4≈ 460 µm | 4.8 – 5.7 |
| AeroPress (short steep)For 1–2 minute recipes. Go coarser for longer steeps. | 6.1≈ 500 µm | 5.7 – 6.6 |
| Pour over — V60 / coneThe reference point for most published pour-over recipes. | 7≈ 560 µm | 6.6 – 7.8 |
| SiphonMedium. Short contact over steady heat, so start here and taste. | 7.4≈ 590 µm | 6.8 – 8.3 |
| Pour over — flat bottomKalita, Orea and similar. Slightly coarser than a cone. | 7.8≈ 610 µm | 7.1 – 8.7 |
| Steep and release — Clever / SwitchSteep, then drain through a paper filter. If it drains slowly, go coarser. | 8.2≈ 640 µm | 7.4 – 9.1 |
| Drip / batch brewAutomatic brewers. Coarser to suit the longer contact time. | 8.5≈ 660 µm | 7.8 – 9.6 |
| CuppingMedium-coarse, for tasting side by side. Keep it the same across every bowl. | 8.7≈ 670 µm | 7.9 – 9.6 |
| ChemexThe thick filter needs a coarser grind to avoid stalling. | 9.6≈ 730 µm | 8.7 – 10.7 |
| French pressCoarse. Too fine here is the usual cause of a muddy cup. | 11.3≈ 840 µm | 10.5 – 11.8 |
| Cold brewCoarsest setting you have. 12–18 hours of contact. | 12.3≈ 900 µm | 11.8 – 13 |
≈ µm is the particle size, approximate, after Honest Coffee Guide’s scale for the VTA 6S. It is not the maker’s microns per click, which measure how far the burrs move.
How much room you have to adjust
That is the resolution you actually have to work with on the VTA 6S. Where the number is small, a single step moves the cup more than you would expect — so change one at a time and taste before moving again.

Convert a grind setting to the VTA 6S
If a recipe quotes a setting for a different grinder, this maps it onto the VTA 6S’s dial using the same curve the chart above is built from.

How these numbers were worked out
Every grinder gets mapped onto a shared 0–100 grind index, where 0 is espresso-fine and 100 is the coarsest useful setting. Five reference points on the VTA 6S are placed on that scale — espresso, moka, filter, French press and coarse — and the settings in between are interpolated.
The VTA 6S joined the catalog in October 2026. Its reference points were worked out rather than read off a maker’s chart: Honest Coffee Guide places every setting on this grinder on one scale of particle size, and each point sits where that scale reaches the size the same method lands on across the grinders we have checked. We couldn’t confirm whether these numbers are printed on the grinder or counted from where the burrs touch, so check your own dial before relying on the ends of the range. That makes them a starting point rather than a specification, and they are marked unverified until a manufacturer’s chart confirms them. Sources: Honest Coffee Guide, mahlkoenig.com.
The VTA 6S’s dial is interpolated linearly between those reference points, which is the right model for its burr geometry.
The result is that “medium-fine” resolves to a real number on this grinder rather than a vague instruction. It is a starting point, not a guarantee — burr wear, bean density and roast level all move the target, which is why every row above gives a range as well as a number.
