For our April 2026 video, we ran five grinders on the same espresso machine, with the same coffee and the same extraction targets, and the cheapest of the five, the 1Zpresso JX-Pro S hand grinder, outperformed the Fellow Opus, the electric closest to it in price. The video walks through each grinder; the text below works from each maker’s published specs and from published measurements.
Our grinder science post makes the case for spending on the grinder before the machine; this page compares specific grinders.
Six grinders, by their makers’ specs
Each grinder’s name links to its maker’s page or manual, checked October 15, 2026. The specs are as published by the maker.
| Grinder | Burrs; adjustment | Dosing |
|---|---|---|
| 1Zpresso JX-Pro S | 48 mm (the JX’s burr); 12.5 µm per click, 40 per turn | Hand grinder, 30–35 g |
| Fellow Opus | 40 mm stainless steel conical; 41 settings plus an inner ring | Timed stops, 30 s to 2 min |
| Baratza Sette 270 | 40 mm conical (S1); macro steps plus a stepless micro ring | Timer, to 0.1 s |
| Turin DF64 Gen 2.7 | 64 mm flat, steel or Red Titanium; stepless collar | Single-dose, about 50 g |
| Eureka Mignon Silenzio 55 | 55 mm flat, hardened steel; stepless | Timer; 300 g hopper |
| Niche Zero | 63 mm conical; stepless dial | Single-dose |
The grinders in more detail
1Zpresso JX-Pro S
1Zpresso says the JX-Pro “is suitable for both pour-over and espresso”, and that its 12.5-micron adjustment “makes finding the espresso sweet spot easy”. The S version adds a folding handle. 1Zpresso’s chart puts espresso at 12–16 on the dial, counting 10 numbers to a turn from a zero where “the handle starts to spin with resistance”. It’s a hand grinder, so you crank every dose.
Fellow Opus
Fellow’s guide for the original Opus puts espresso between 1 and 2 on its outer ring. On the ring’s quarter steps that’s five positions (calculated), and Fellow suggests the inner ring for finer espresso adjustments. Fellow now sells the Opus 2, with 48 mm conical burrs and a stepless dial; the row above is the original.
Baratza Sette 270
Baratza pairs macro steps with a stepless micro ring for what it calls “270 pinpoint grind sizes”, and the timer doses to a tenth of a second. Its no-chute design drops the grounds straight from the grind chamber into the portafilter. Baratza includes shims to customize the grind range, and says it grinds “anything from espresso to single-cup pour overs”.
Turin DF64 Gen 2.7
An earlier version of this page covered the DF64 Gen 2.5; Turin’s current listing is the Gen 2.7, with a revised chute and ion-generator probes to cut static. It has 64 mm flat burrs, a stepless collar and a fixed-speed 250 W motor, and Turin says its burrs cover espresso and filter.
Turin offers SSP aftermarket burrs separately and notes that they “require installation and alignment”. Our burr alignment guide covers what that involves, including Turin’s own view that alignment isn’t needed in most cases. For light roasts at fine settings, Turin suggests switching the grinder on and pouring the beans in slowly.
Eureka Mignon Silenzio 55
The Silenzio 55 has 55 mm flat burrs of hardened steel, which Eureka rates at a 300 kg lifespan, and a stepless adjustment that moves the lower burr, so you can do maintenance without losing your setting. Eureka rates the burrs for “All Purpose” use, with output figures for both espresso and brew. It weighs 5.6 kg, and Eureka’s Silent Technology uses an anti-vibration system to cut grinding noise.
Niche Zero
The Niche Zero has 63 mm conical burrs and a stepless dial, and Niche lists its noise at 72 dB while grinding. Niche advertises “zero retention”; in Gagné’s 2021 espresso comparison, his Niche Zero retained an average of 0.18 ± 0.04 g. Niche’s own guide puts espresso between 5 and 20 on the dial. It sells direct from Niche’s site, with a US plug option.
What separates espresso grinders
Four things come up again and again in the published work:
- Sharp burrs. Rao writes that sharper burrs make a narrower spread of particle sizes, and that as burrs dull they make both more fines and more boulders, which always nets out to slower flow and lower extraction. His illustration has a coffee’s best extraction falling from 20.5% to 19.0% as a burr set wears over 30,000 shots.
- Burr size. Rao says larger burrs make fewer fines and a narrower spread, enough that some large-burr grinders reach 21% extractions where some small-burr grinders can’t taste good above 19.5%. Gagné’s 2023 analysis of 24 espresso grinders measured by the Kaffeemacher team and the ZHAW found that, within that sample, larger burrs didn’t systematically grind more evenly; burr geometry and coating looked more important.
- Alignment. Gagné cautions that there was no way of knowing whether the grinders in that data set were well aligned, which could plausibly affect their results. See the alignment guide.
- Adjustment. The step size each maker publishes tells you how small a change you can make, from 12.5 µm per click on the JX-Pro S to stepless dials.
Flat versus conical matters less than the labels suggest. In the same analysis, conical burrs were on average less even, but the overlap was large: a specific flat burr can easily be less even than a specific conical one. Our conical vs flat burr grinders post goes further.
Finding your espresso setting
Each maker’s number only means something on its own grinder. Two published starting points for espresso:
- 1Zpresso’s JX-Pro chart: 12–16 on the dial.
- Niche’s guide for the Niche Zero: 5–20.
Fellow’s chart puts the Opus between 1 and 2. Turin’s and Eureka’s product pages give no espresso setting for these models.
Then dial in by taste and time; our espresso dial-in guide walks through it.
Where to buy
