Starting settings
These are the settings each creator gave, measured from their own grinder's zero. Use them as a starting point.
| Method | Setting | Context | Confidence | By | Source |
|---|---|---|---|---|---|
| Espresso | 1 to 1.4 | Daddy Got Coffee's usual range on his M47 Classic. Each tick is about 2 to 3 s of shot time | stated | DGC | 16:19 |
| Pour-over | about 4 revolutions from zero | Stock burr on Daddy Got Coffee's grinder. Others report about 5, since grinders zero differently | approx | DGC | 16:19 |
| Pour-over | 3 to 4 revolutions (Pour Over burr) | Kinu Pour Over inner burr for maximum clarity. Go 2 to 3 revolutions for a sweeter, heavier cup | stated | DGC | 9:16 |
| Pour-over | about five revolutions off the zero point | A starting point against a dialled-in C40. It brewed in a similar time but came out under-extracted and weak | approx | DGC | 8:12 |
| Pour-over | about a full revolution finer than that start | Light roasts. It reached C40-like extraction with better flavour, and the brew time barely changed | approx | DGC | 9:13 |
| Pour-over | two to three revolutions | Roughly a full revolution finer for a more intense, blended cup with heavier body, using a low ratio and low agitation | approx | DGC | 10:46 |
| Immersion | 3.5 | 2020, rotations then numbers scale. Reader-submitted and approximate | approx | Christensen | grind size chart |
| Pour-over | 3.0 | 2020, rotations then numbers scale. Reader-submitted and approximate | approx | Christensen | grind size chart |
| AeroPress | 2 | 2020, rotations then numbers scale. Reader-submitted and approximate | approx | Christensen | grind size chart |
| Moka | 1.8 | 2020, rotations then numbers scale. Reader-submitted and approximate | approx | Christensen | grind size chart |
| Espresso | 0.9 | 2020, rotations then numbers scale. Reader-submitted and approximate | approx | Christensen | grind size chart |
Cup profile
- It leans traditional but is still good for filter. It was Lance Hedrick's favourite for espresso in 2022 15:52.
- Sweetness and a silky body. Lance Hedrick uses it as his reference when comparing sweet and clear burrs 14:26.
- Sweet, syrupy, balanced espresso, likened to Lab Sweet-style burrs 13:40.
- The pour-over burr is very clear, though more blended than a ZP6 22:39. It has balanced acidity and higher clarity than the K series 1:32.
Strengths
- Fast, at under 30 s for a filter dose 15:52.
- Matches or beats many large electrics for traditional espresso 13:40.
Weaknesses
- Plastic catch cup unless you buy the magnetic one 15:52.
- The knob-style dial is annoying 22:39 and less usable than external clicks 13:40.
- Not the best for light roasts 13:40.
- Swapping in the pour-over burr risks centring 12:07.
Verdict
In 2022 it was part of Lance Hedrick's "holy trinity" of hand grinders 15:52. His 2024 tier list graded the M47 an A 22:39. In 2025 it edged the J-Max in the cup but lost on usability 13:40. With pour-over burrs it was roughly level with a Timemore 078 for filter, with the 078 slightly ahead for him 1:32.
James Hoffmann's take
- It was his overall pick in the 2019 hand-grinder showdown, for build, usability and cup quality in both espresso and filter. Each step moves the burrs about 10 µm, and early on his espresso settings drifted until the burrs had seasoned 17:14 20:05.
Daddy Got Coffee's take
- In 2025 he found the espresso nuanced and fuller-bodied, even with light roasts, where it beat his Niche Zero. The stock burr makes great light-roast pour-over if you grind about a revolution finer than the usual very coarse advice. Drawdown time barely changes, so judge by taste 1:31 8:42 11:44.
- He calls the Pour Over burr a chameleon. Very coarse gives ZP6-like clarity, and a revolution finer gives a sweeter, blended cup, even though the particle spread is wide 0:00 5:40 7:13.
The Coffee Chronicler's take
- In 2025 he tried the Phoenix. It made rich, textured classic espresso, and pour-over that was more blended than heptagonal cones give. The fixed handle makes switching methods slower to adjust, the plastic cup is flimsy, and 18 g takes about 50 s. He found it solid but pricey for the plastic at $250 9:44.
