KINGrinder K4 grind settings
Where to set the KINGrinder K4 for every common brew method — worked out from this grinder’s own dial curve rather than a one-size-fits-all chart.
The shape of this dial
The top line is the universal grind index every BrewMark recipe uses. The bottom line is the K4’s own dial. The connectors show how one maps onto the other.
Settings by 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 |
|---|---|---|
| EspressoFine. Aim for a 25–30s shot and adjust from there. | 23 clicks | 15 clicks – 35 clicks |
| Moka potFiner than filter, coarser than espresso. No tamping. | 40 clicks | 35 clicks – 49 clicks |
| AeroPress (short steep)For 1–2 minute recipes. Go coarser for longer steeps. | 58 clicks | 49 clicks – 72 clicks |
| Pour over — V60 / coneThe reference point for most published pour-over recipes. | 82 clicks | 73 clicks – 92 clicks |
| Pour over — flat bottomKalita, Orea and similar. Slightly coarser than a cone. | 92 clicks | 85 clicks – 101 clicks |
| Drip / batch brewAutomatic brewers. Coarser to suit the longer contact time. | 99 clicks | 92 clicks – 108 clicks |
| ChemexThe thick filter needs a coarser grind to avoid stalling. | 108 clicks | 101 clicks – 118 clicks |
| French pressCoarse. Too fine here is the usual cause of a muddy cup. | 126 clicks | 117 clicks – 137 clicks |
| Cold brewCoarsest setting you have. 12–18 hours of contact. | 148 clicks | 137 clicks – 165 clicks |
How much room you have to adjust
That is the resolution you actually have to work with on the K4. 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.
Dialing in the K4
External adjustment at a notably low price, which is the whole proposition. Its click resolution is finer than most grinders in its bracket, so small movements do less than you might expect — move in larger increments than you would on a C3.

Convert any recipe’s grind setting to your K4
If a recipe quotes a setting for a different grinder, our converter maps it onto the K4’s dial using the same curve this chart is built from. 80+ models supported.

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 K4 are measured against that scale — espresso, moka, filter, French press and coarse — and the settings in between are interpolated.
Because the K4 uses conical burrs, the curve between those points is fitted with a monotone cubic spline rather than straight lines. Conical burr dials are rarely linear, and the spline guarantees the curve never doubles back — a coarser index always produces a coarser setting.
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.
