Most of the attention in a coffee setup goes to the machine, which is not entirely wrong but is a long way from right. The bean matters just as much, and so does grinding it fresh with a decent mill set correctly. Coffee's flavour comes from more than 800 separate aroma compounds that are only released as the bean is broken up — and roughly 30 per cent of them are gone shortly after grinding. However well it is packaged, pre-ground coffee is not a real alternative to grinding your own.
This covers 24 electric grinders from a single test, from an entry-level mill to professional-grade machines. Hand grinders are a separate category and are not included.

Best Overall: Eureka Mignon Specialità
Made by an Italian firm that has been building grinders and espresso machines for over a century, and aimed at experienced home baristas. It is a stainless-steel machine with a striking, angular and genuinely compact shape, available in a range of colours, and the build quality is high throughout.
The mechanism is a 55 mm stainless steel flat burr with stepless grind adjustment, and at 5.6 kilograms the machine stays put on any worktop. The removable hopper holds up to 250 grams of beans. Grind size is set with a small knob, and the display handles dose and grind time. It barely builds up any static and releases almost all of the grounds it produces rather than keeping them inside. The portafilter holder is adjustable, so baskets from different espresso machines fit.
Once you have found the right setting it produces very homogeneous, fine grounds at a professional standard. At around 79 decibels it is one of the quieter machines here, and cleaning is straightforward — the hopper lifts off and a few screws expose the burrs, and your settings survive the process.
Two honest caveats. It does not enjoy being moved constantly between fine and coarse: switch to filter coffee and you will be readjusting and tasting until it is right again, though the test notes that most grinders in its class behave the same way. And the hopper sits on a narrow seat, with a lid that feels as though it could crack. Search Amazon UK · Amazon US
For Serious Espresso: Lelit William PL72
The specialist, and the one with the professional components. Its 64 mm stainless steel flat burrs produce exceptionally homogeneous grounds at 2.8 grams per second, notably quicker than much of its competition. The solid stainless housing weighs 6.6 kilograms, which keeps it stable and damps the noise down to 74.8 decibels — quieter than the overall winner. It builds up practically no static at all, so very little of what it grinds is lost on the way out.
It is set up for real use: the portafilter holder is height-adjustable, the ejection angle can be adjusted, and there are two programmable doses for single and double shots. Grind adjustment is micrometric and precisely done.
The flaw is the interface. Its display-driven control centre makes the machine unnecessarily complicated, and setting the dose is close to unguessable without the manual — genuinely annoying on an espresso grinder, where you readjust every time you open a new bag of beans. The strengths still outweigh it. Search Amazon UK · Amazon US
Best for Filter and French Press: Baratza Encore ESP
An upgrade of a long-standing favourite, and visually almost identical to it — the same plain plastic housing, the same 40 grind settings. The ESP suffix promises usable espresso grinds, and it delivers: the grounds at fine settings are far more even than its predecessor managed. Even so, this is a machine to buy for filter coffee and the French press, where it does its best work.
It runs on a good stainless steel conical burr, is easy to operate, and has sensible adjustment. The revision brought real improvements: the burr runs more smoothly and quietly, there is less dead space inside, and static is low. The catch bin and housing were upgraded in material too.
Its one practical limitation is dosing. There is no portafilter holder, only a catch cup, which makes measuring a shot precisely more awkward than it should be. Search Amazon UK · Amazon US
Also Tested
Sage The Smart Grinder Pro was previously the espresso recommendation and remains a strong all-rounder at a lower price than the Lelit. Its stainless conical burr offers 60 grind settings covering espresso, filter and French press; grind time is programmable and shown along with the setting on a modern display. It is a lot of machine for a beginner and oversized next to a simple espresso machine, and adjusting the grind time in 0.2-second steps or using the portafilter contact switch assumes some familiarity. Use a coffee scale with its grind-by-weight function. The supplied portafilter holders sit tightly, so take care not to spill grounds when removing them. Search Amazon UK · Amazon US
Baratza Sette 270W is the luxury option and the fastest machine in the test at 3.5 to 5.5 grams per second — the less time a bean spends between the burrs, the more aroma survives — and it stays remarkably homogeneous at that speed. Adjustment is stepless and accurate from coarse to very fine, and a built-in scale with a front display removes the need for a separate one. The heat-producing motor is placed as far from the beans as the design allows, and the grounds drop straight into a portafilter or a filter, the two swapped in seconds. It needs worktop space.

KitchenAid Artisan 5KCG8433E is the quiet one, with a high-quality stainless burr and 70 grind settings producing very fine, homogeneous results. It can grind for espresso but is at its best at coarser settings for filter and French press. It cleans easily, generates no static, has a display, and doses automatically by cup or by time.

Melitta Calibra has the feature most of this field lacks: an integrated scale, which with its stainless conical burr allows genuinely exact dosing. The grounds are fine and homogeneous and there are enough settings to experiment with, making it a reasonable choice for beginners and improvers alike. What keeps it from the top is the rest of the package — a somewhat clunky design, a noise level that becomes wearing, and noticeable static. Search Amazon UK · Amazon US
Rommelsbacher EKM 400 sits between the entry-level machines and the specialists, with a stainless conical burr and 35 grind steps that produce homogeneous results, particularly at medium to coarse settings. Against the cheaper EKM 200 it adds a 200-watt motor and an LED display, and doses in finer 0.1 steps, though without a scale it is not gram-accurate. At 79.3 decibels it is relatively loud, and despite an antistatic function some grounds still cling. Not quite a recommendation, but a solid filter-coffee machine. Search Amazon UK · Amazon US
Rommelsbacher EKM 200 is the beginner's machine, offering 63 grind settings from nine main steps of seven sub-steps each while staying simple to handle. The compromises are real at the price: the plastic housing builds static and leaves grounds behind, grind duration cannot be varied on its own but only by portion size, and the adjustment feels notchy. The burr itself is steel and well made.
Graef CM 800 is a genuine all-rounder among entry-level mills, competent across every grind from cold brew to espresso and not especially loud despite its conical burr. Its chrome-alloyed stainless conical burr grinds evenly across all 40 settings. Two small drawbacks: the settings are not stepless, which only matters as your standards rise, and thorough cleaning is complicated by static in the plastic housing and a built-in catch.
Solis Scala Zero Static does what its name says — it is genuinely antistatic, so grounds do not cling. Quiet and well built, with a stainless conical burr that grinds fine enough for an espresso machine. Gram-accurate grinding is not possible, so a coffee scale is part of the deal.
Tchibo's electric grinder suits hand filter, cold brew, French press and filter coffee, with 26 grind steps and quantities set by cup, weight or time, dosed through an integrated scale. It is a good machine to learn on, with plenty of fine-grained adjustment, sound results and a stainless housing — but it does not manage espresso.
Baratza Encore, the model the ESP replaced, remains a fine choice for filter and French press. Its plastic body builds almost no static, which keeps grinding tidy, and the long cable means you can use it anywhere. Its 40 mm conical burrs give evenly sized grounds at every setting coarser than espresso. Marks against: a loud burr, and of the 40 settings only about 28 are genuinely usable, because the first 12 grind too coarse even for a French press.
Zassenhaus Kingston is well made and inexpensive, in a timeless stainless finish, and it runs very quietly. Despite a stainless flat burr it does not deliver homogeneous, aroma-preserving results at every setting: it is fine for French press and filter, just about copes with a stovetop pot, and does not grind espresso beans finely enough. Static is its other drawback.
Melitta Molino is aimed at beginners and did not do well here. Its flat burr offers only 17 settings, which is not enough for demanding use, though it does grind fine coffee very homogeneously and so can manage espresso. It is relatively loud, and the plastic body generates so much static that a thorough clean is needed after every use.
Braun FreshSet KG 7070 failed the test. Static is extreme and grounds stick everywhere, handling and cleaning are too complicated, and despite a stainless flat burr with nine settings the grounds are neither fine enough nor evenly sized. It is usable for a French press or a percolator and not much else.
Electric or Hand-Cranked?
A hand mill grinds anywhere, with no power, and with decent gearing the work is easy — but only in small quantities. An electric grinder makes the job trivial and comes in a huge range of models with correspondingly wide differences in quality.
Which Burr Type?
Flat burrs are the most common: the bean is ground between two discs and the grounds are carried outwards. Conical burrs work on the same principle in cone form, with the grounds falling downwards, which means a lower rotation speed is needed. As for materials, stainless steel burrs are robust and inexpensive but can build heat quickly, while ceramic barely heats at all and is taste-neutral, though more prone to damage than metal.
Then there are blade grinders, which work like a blender and shred the beans irregularly rather than grinding them. Uneven grounds mean uneven extraction, which is why the test advises against them outright. That single decision matters more than almost anything else here: as long as you avoid a blade machine, even an inexpensive mill beats pre-ground coffee comfortably, and the difference surprises most people — including when the brewing is done by an ordinary filter machine.
How to Spot a Good Grinder
Beyond the burr type, a good mill shows itself in use. Look for high-quality, stable construction; simple handling; and stepless grind adjustment, or at least plenty of intermediate steps. The grounds should not be heated during grinding, and the particles should come out uniform in size and shape. Static build-up and grounds retained inside the machine should both be as low as possible.
Where a maker quotes a grind rate in grams per second, higher is better: the faster the beans pass through, the less time they spend heating up, and the more of the delicate aromas survive. The rest is practical — settings you can change without tools, a manual or fiddling; a short grind at a tolerable volume; a machine that sits securely on the worktop; and no heat from either the motor or the burrs.
Getting the Grind Right
Adjust for each bag of beans. No two varieties are the same: surface and roast level differ, and both change the texture of the grounds. Every fresh bag means readjusting, tasting and building up experience until the grind size and duration are right.
Consider two grinders if you drink both. Each brewing method needs different grounds. If it is French press in the morning and espresso in the afternoon, you are resetting the machine at least twice a day and starting the fine-tuning again each time. A dedicated espresso grinder alongside a coarser mill solves it.
Clean it regularly. No water or milk is involved, but grinding is not a clean process: beans carry oil that settles and can turn rancid, and grounds are left behind every time. You can either take the mechanism apart and vacuum it carefully, or run a cleaning cycle with cleaning granules made for the job. The test prefers the manual route, on the grounds that you can see it is actually clean.
How the Testing Worked
Every grinder was lined up side by side and assessed first on appearance — design, weight and dimensions — then examined individually for build quality.
The grinding itself was judged under conditions as consistent as possible, which is harder than it sounds: different brewing methods need different grind sizes, different beans and, realistically, different machines. Rather than pick one standard, the testers bought a range of fresh beans in different roasts and ground them on every machine for every style of coffee, which is what surfaces each model's speciality — and why several machines here are recommended for one brewing method and not another.
