Porlex Mini / Tall II grind settings.
The travel grinder that fits inside an AeroPress. Thirteen clicks, and a chart that reflects how few that is.
The chart
Starting points, not targets. Each number carries a ± 1-click band because that is the honest resolution of this dial — land inside the band, then let taste move you.
| Brew method | Porlex clicks |
|---|---|
| Espresso anchor | 3 ± 1 |
| Moka pot | 4 ± 1 |
| AeroPress (short, fine) | 4 ± 1 |
| V60 / pour-over | 6 ± 1 |
| Kalita Wave | 6 ± 1 |
| Chemex / batch drip | 7 ± 1 |
| Clever / switch immersion | 8 ± 1 |
| French press anchor | 11 ± 1 |
| Cold brew | 12 ± 1 |
One click on this grinder moves the grind by about 0.76 of a point on the 1–10 universal scale — so roughly 1 click is the smallest change worth making between brews.
A chart gets you a starting number and then stops. Coffee Aeye quotes every recipe in Porlex clicks to begin with — and when you rate the brew, it tells you which way to move and how many, on this dial.

Two anchors, and interpolation between them. Espresso and French press are the only two bands that manufacturers and community charts actually document with any consistency, so those are the fixed points: espresso at 3 and French press at 11. Everything between is a straight line drawn through them, quantised to the click this dial actually resolves.
Absolute accuracy is not possible and this page will not claim it. Burr wear, per-unit zero points and assembly tolerances all shift where a number lands. What the two-anchor method gives you is the right shape — correct spacing between methods, correct direction of travel — which is what you need to dial in efficiently. The rest comes from calibration.
How this grinder works
A click nut under the burrs, zeroed at contact. Mini and Tall II share the same burr set and adjustment pitch and differ only in hopper capacity, so one chart covers both. The full brewing range spans under nine clicks.
Calibrating the chart to your own Porlex
If the chart runs consistently coarse or fine for you, do not nudge every row. Re-anchor it:
- Find your espresso mark — the click where a 1:2 shot in about 28 seconds actually happens on your machine. If you do not pull espresso, use the finest point where a moka pot does not choke.
- Find your French press mark — coarse enough that a four-minute steep is clean rather than muddy, and the plunger does not fight you.
- Enter both in Coffee Aeye. Replacing the two anchors corrects the zero point and the slope at once, and every method in between re-derives from your own two numbers.
This matters more on some grinders than others — it matters most anywhere the dial is stepless or the zero is set by hand.
Known quirks of the Porlex
Mini and Tall II are the same grinder for dialling purposes.
Different capacity, identical burrs and identical click pitch. Settings transfer between them exactly.
It nests in an AeroPress, which is most of the point.
The chart's AeroPress row is the one that matters — this grinder is built around that pairing, and it is where the limited range hurts least.
Very few clicks across the whole range.
Espresso to French press in under nine clicks. Like the Skerton, adjustments are blunt instruments. Use ratio and temperature for fine control, because the grind cannot give it to you.
Moving the dial when a brew tastes wrong
The chart gets you into the right neighbourhood. Taste gets you the rest of the way, and the rule is the same on every grinder here:
| What you taste | What it means | Move |
|---|---|---|
| Sour, sharp, thin, empty finish | Under-extracted | Finer |
| Bitter, drying, harsh, ashy | Over-extracted | Coarser |
| Balanced but weak | Ratio, not grind | Hold |
| Balanced but overwhelming | Ratio, not grind | Hold |
On this dial, 1–2 clicks is one meaningful step. Change one thing per brew. The full method is in the V60 dial-in guide.
Coffee Aeye holds this chart for all 18 supported grinders and closes the loop on it. Rate a brew and it converts the fault you tasted into a concrete move — how many clicks on your Porlex, in your own dial numbers, not a vague "grind finer". Calibrate your two anchors once and every recipe in the app re-derives to your unit. Get it on Google Play — €4.29, one-time.
Convert a setting to another grinder
Settings do not transfer between grinders — click sizes, burr geometry and zero points all differ. The grinder converter maps a Porlex setting onto any of the other 17 through the same universal scale this chart is built on.
