Corrections
Every setting we got wrong, and what changed
A grind chart is only useful if you can trust it, so mistakes are listed here rather than quietly fixed. Each entry says what the page showed, what it shows now, and who or what caught it. Spotted another? Tell us.
Mazzer Mini and Super Jolly: settings withdrawn
- Was
- Both charts counted whole rotations of the collar, with filter at 5 rotations on the Mini and 4 on the Super Jolly. Mazzer counts printed collar numbers from where the burrs touch, and a forum measurement puts a full turn at about 10 numbers, so the charts were roughly ten times too coarse.
- Now
- The Mazzer pages no longer give a full chart. The contact point differs between units and Mazzer doesn't say how many notches make a number, so no figure holds across units. The pages now quote Mazzer's own reference points, such as espresso about 1 number and 4 notches from contact, and explain how to dial in from there.

- Mazzer's own grinder tutorial
Fellow Ode and Opus: settings written as marks the dial has
- Was
- Positions between numbers were written as decimals of the true value, so the second mark after 4 on an Ode read "4.7" and the first read "4.3". The Ode has only two marks between numbers, so those read as positions it does not have.
- Now
- Written as the number and which mark after it, the way owners count them: on an Ode, 4, 4.1, 4.2, then 5; on an Opus, up to 4.3. The positions themselves did not change. A setting typed as 4.2 for these grinders is now read as the second mark.
- Caught by
- A reader with an Ode Gen 2, and third-party Ode charts that write marks this way
Baratza Forte BG: settings written as the dial reads them
- Was
- The settings chart counted the 260 micro steps end to end and printed numbers like "96", which appear nowhere on the grinder. Only the shop widget wrote the macro number and micro letter.
- Now
- Every page now writes macro 1–10 and micro A–Z, as Baratza labels the dial: "4R" is macro 4, micro R. The positions did not change.
- Caught by
- Baratza's Forte manual
Burr type corrected on three grinders
- Was
- The Varia VS3 and Lagom Mini were listed as flat burr and the Cuisinart DBM-8 as conical. Burr type picks the curve every setting is read from.
- Now
- VS3 and Lagom Mini are conical (48 mm, per their makers); the DBM-8 is flat.
- Caught by
- The makers' specifications and the Cuisinart manual
Mahlkönig X54: wrong dial length
- Was
- The dial was modelled as 1–15. It is marked 01–35, so most settings shown were too low.
- Now
- Re-derived on the real 01–35 dial: espresso 01–05, filter 15–25, French press above 25, as in Mahlkönig's manual.
- Caught by
- Mahlkönig's X54 manual
Baratza Encore ESP: espresso and filter settings
- Was
- Espresso was shown at 7 and a V60 at 17.7, from an aggregator table that disagrees with Baratza.
- Now
- Re-derived from Baratza's operating manual: espresso 15, AeroPress 22, V60 25, French press 32.
- Caught by
- Baratza's operating manual v1.0
Kafatek Monoliths: settings withdrawn
- Was
- Both Monoliths showed pour over at 4 rotations and espresso at 0.5. Those were placeholder numbers, identical for two different grinders, and never read off a real dial. On an early Flat Max, 4 rotations is far too coarse for pour over.
- Now
- The Monolith pages no longer give a number. Kafatek has changed the dial and thread between versions, and the collar is unmarked, so no figure holds across units. The pages now explain how to dial in from your own zero point.
- Caught by
- An owner of an early Flat Max, by email
46 grinders checked against published charts; 25 were wrong
- Was
- Many charts were filled from shared templates. Ten of the wrong rows had the wrong dial length, so they printed settings that do not exist on the grinder.
- Now
- Every row with a published per-method chart was checked and corrected, and each check is recorded so it can be re-run. Grinders without one are marked unverified on their pages.
- Caught by
- Makers' charts and published per-method tables
Breville built-in grinders: one dial copied three times
- Was
- All three were given the same 1–18 dial. The Barista Express has 16 settings, the Express Impress 25 and the Touch Impress 30.
- Now
- Each chart now uses its own dial, with every method kept in the same place relative to it.
- Caught by
- Breville's own product and tutorial pages
Baratza Encore: cold brew too fine
- Was
- Cold brew showed 31.8 against published guidance of 35–40.
- Now
- The French press and coarse reference points were corrected; all nine methods now sit inside published ranges.
- Caught by
- Published per-method guidance
Fellow Ode Gen 2: French press too fine
- Was
- French press showed 8.2, below every published figure (9.0–9.2).
- Now
- French press is now 9.1 and cold brew 10.2.
- Caught by
- Published per-method tables
Timemore C3 and C2: pour over too coarse
- Was
- Both showed pour over at 20 clicks, against published ranges of 11–18 (C3) and 14–18 (C2). The two had identical numbers despite different burrs.
- Now
- Pour over is now 15 clicks on the C3 and 16 on the C2, with French press and cold brew corrected to match.
- Caught by
- Published per-method tables
Fellow Opus: settings off the end of the dial
- Was
- The Opus was modelled as a 1–41 dial, so the page showed settings like "French press 24.7" on a dial numbered 1–11.
- Now
- Rescaled to the printed 1–11 ring. The anchors are still marked unverified pending Fellow's own guide.
- Caught by
- Fellow's gear guide
1Zpresso grinders: settings for the wrong dial
- Was
- Seven 1Zpresso grinders carried reference points worked out for a different dial range, so their settings were unusable.
- Now
- Each was re-derived for its own dial, and the fix was carried through to the converter.
- Caught by
- 1Zpresso's published settings
