Grinders, espresso
Ranked on the two things espresso needs and filter does not: fine, precise adjustment, and consistency at a fineness where small errors become large ones.
Espresso is the demanding case. Filter brewing tolerates a wider spread of particle sizes because water passes through slowly under gravity; espresso forces water through a compressed bed at nine bars, and every inconsistency becomes a channel.
That means two requirements that filter grinders can ignore. The adjustment must be fine enough to move a shot by a couple of seconds, and the grind must be consistent at a fineness where fines clog and boulders let water through. Our ranking below is by how well each grinder meets those two demands, not by price.
Retention and adjustment matter less: you set it once and leave it. A stepped grinder is plenty.
Every change of bean needs a new setting, and coffee left inside mixes into the next dose. That is where retention becomes concrete.
The range has to cover two worlds. Few grinders do it well, and those that claim to often do one end badly.
Burrs heating up shift the grind across doses. It is a real effect, especially on small compact grinders.
| Your use | What matters most | What matters little |
|---|---|---|
| One coffee, set once | Burr uniformity | Retention |
| Varied coffees | Stepless, low retention | The timer |
| Espresso and filter | Range width | The finish |
| Several cups in a row | Burrs that stay cool | The display |
An espresso grinder degrades through oils before burrs. Oily coffee leaves a deposit that goes rancid and ends up in the cup. No burr life can be stated: it depends on how much you grind and on the roast level.
Burrs spin fast and do not stop instantly.
55 mm (2.17 in) flat burr · stepless · near-zero retention
Stepless adjustment, 55 mm (2.17 in) flat burrs and almost nothing left in the chute — the three things that separate a serious espresso grinder from a good one. It is quiet enough to use at six in the morning without an argument.
Best for: A Gaggia Classic, Lelit or Rancilio owner who has stopped blaming their technique.
40 mm (1.57 in) conical · 40 espresso steps + 20 filter
The cheapest electric grinder that genuinely does espresso and filter without being bad at both. Forty fine steps in the espresso range is the whole point — and Baratza will still sell you a burr set for it in ten years.
Best for: Anyone pairing a grinder with a Gaggia Classic, a Dedica upgrade, or a Barista Express they have outgrown.
39 mm (1.54 in) nitrogen-hardened burr · hand · filter & espresso
The hand grinder others are measured against, and priced accordingly. Grinds better than electric grinders at twice the money, and asks for your arm every single morning.
Best for: One or two exceptional cups a day, travel, and anyone who values the object.
38 mm (1.50 in) stainless burr · hand · espresso-capable
Out-grinds electric grinders costing three times as much, provided you accept the arm. The ESP burr reaches espresso fineness with real adjustment — which is not true of most hand grinders at any price.
Best for: One or two coffees a day, or a travel grinder that does not compromise.
Neither is universally better. Flat burrs give a narrower particle distribution, which reads as clarity and separation — you taste individual notes. Conical burrs give a rounder, heavier, more forgiving shot. Light single origins favor flat; dark roasts with milk make the difference nearly invisible.
The setting you want always exists. With stepped adjustment you sometimes need a grind between two clicks and cannot have it. The cost is repeatability — there are no numbers to return to, so owners mark the collar with tape or a pen.
Only if you single-dose. If you weigh in exactly what you intend to brew, a gram of retention means yesterday comes out first and today stays behind. If you keep a full hopper and grind on demand, retention is irrelevant.
Between two doses of the same coffee, no. After a change of setting or of bean, yes: what sits in the chute comes out with the next dose and skews the result.
Yes, and often well: for the same money a hand grinder has better burrs. The limits are the effort, real at fine settings, and the slowness if you serve several coffees.
When the grind turns uneven and adjustment no longer rescues it. No lifespan can be quoted: it depends on kilos ground and on roast level, not on the calendar.
Not necessarily, but it must not be trivial next to it. A heavily machine-weighted split is the commonest arrangement and the most regretted.
Static, made worse by dry air and light roasts. A drop of water stirred into the beans before grinding cuts it down sharply.
Aimed at: A Gaggia Classic, Lelit or Rancilio owner who has stopped blaming their technique.
Best thing about it: Stepless micrometric adjustment — infinite positions, not clicks
Worst thing about it: Overkill for anything but espresso; the filter range is an afterthought
Aimed at: Anyone pairing a grinder with a Gaggia Classic, a Dedica upgrade, or a Barista Express they have outgrown.
Best thing about it: 40 closely-spaced steps in the espresso range — you can actually dial a shot
Worst thing about it: Retention of roughly a gram means single-dosing needs a bellows or a tap
Aimed at: One or two exceptional cups a day, travel, and anyone who values the object.
Best thing about it: Nitrogen-hardened steel burrs that stay sharp for years of daily use
Worst thing about it: Very expensive for a device with no motor
Aimed at: One or two coffees a day, or a travel grinder that does not compromise.
Best thing about it: Grind quality genuinely competes with 200-euro electric grinders
Worst thing about it: About 40 seconds of steady cranking per espresso dose

Espresso machines and grinders swing by a hundred dollars or more across the year, and the biggest "discounts" often land at prices the same model sold for six weeks earlier. UniverTrack tracks the real price history across retailers, spots fake reductions, and alerts you when it is genuinely the moment to buy.
