Scores, selection and sources
In its review, the Mignon Specialita gets 9.5 for build quality, 9.6 for performance, 8.9 for handling and 8.3 for value for money. On average that would be just under 9.1, but its overall score is 9.4. This number is an editorial judgement and not an average, and that is exactly how the scores are meant on all eight places.
On 1 October 2026, the category electric coffee grinders counts fourteen reviewed grinders. The eight with the highest overall score make it onto this page, the Specialita first and the Fellow Opus with 8.6 last.
The lower end shows where the average lies: no grinder below €139.99 on Amazon.de made the list. The four cheaper ones in the catalogue lie below it with 7.6 to 8.2 points, and right at the edge only the sort order separates two grinders with the same score.
None of these devices has stood on our worktop. All fourteen reviews have been revised; they draw on manufacturer pages and instruction manuals and use the Amazon catalogue as a cross-check. If something is said here about a particular grinder, it can be read up there.
Flat or conical burrs, and what the data sheet says about them
Three of the eight grind between two flat discs, five with a cone that turns inside a ring. The flat-burr grinders have stated diameters: 55 millimetres for both Eureka, 58 for the Wilfa. For the conical burrs, Baratza gives 40 millimetres for both models and so does Fellow, while Graef and Sage name no diameter for their cones.
The two designs work differently in construction. In a cone, the beans are broken up at the top, where the gap is wide, and ground further down; the grind size is set by the narrowest distance at the exit. Between two discs, they travel from the centre outwards until they fit through the gap at the edge. We cannot say which design delivers the more even grounds: none of the eight reviews contains a measurement of particle size, and we have none of our own either.
What can be read off, however, is the mechanics around it. According to the product page, the two Eureka turn at 1,350 revolutions per minute, draw 310 watts and weigh 5.6 and 6.5 kilograms. The conical grinders lie below that, with 550 revolutions for the Baratza, 350 for the Opus and 70 to 165 watts. The Wilfa fits neither group: 58-millimetre discs, but 80 watts, and Wilfa expressly advertises slow grinding. For the Graef, a rotational speed (approx. 800 to 900) appears only in the Amazon catalogue.
Incidentally, in the catalogue the flat burrs sit at both ends of the price scale. At the very top the two Eureka, at the very bottom the two cheapest grinders in the category, both with flat burrs and neither on this list. The design alone therefore says little about price. In our assessment, what matters more when buying is not whether a cone or discs do the grinding, but how the gap can be adjusted.
Stepless, stepped or with a tool
Why the steps matter so much for espresso is explained in the same way by the Sage, Baratza and Wilfa reviews: the water has to pass under pressure through a firmly tamped puck, and how fast it runs through depends on particle size. A French press steeps for several minutes without pressure and forgives a step in grind size far more easily. If the right espresso grind lies between two steps and the grinder has no second adjustment path, all that is left to you is changing the dose.
Only the two Eureka adjust steplessly. The other six have steps, and how many of them belong to espresso varies widely. The Sage table reserves 30 of 60 steps for espresso, Baratza on the Encore ESP 20 of 40, and it calls this half high resolution. The Wilfa provides steps 3 to 7, the Opus the range 1 to 2 with five click positions. The Virtuoso+ has no designated espresso zone; Baratza suggests step 8, below which seven steps remain. For the CM800, Graef gives no step numbers at all, only the rule of thumb fine, medium, coarser.
Four of the stepped grinders have a second lever that reaches beyond the scale, and each costs some handwork. On the Graef you take out the upper burr and reset it with a screwdriver, according to the manual at first by two to three positions at most. On the Sage you move the upper cone by one number after removing the container and the cone. The Opus has a blue inner ring under the bean hopper which, according to Fellow, allows steps of 16.7 micrometres; for this the hopper comes off, and by our reading every correction shifts the whole scale with it. Baratza supplies the Encore ESP with shims that move the range by about five steps but create no intermediate values.
Stepless adjustment has its own price: there is no click to serve as a marker. On the Specialita, you can find a setting again only via the notches on the adjustment knob, and Eureka warns that the machine can stall if the knob is turned a full revolution while the motor is stationary. The procedure step by step is covered under adjusting grind size.
Dosing by seconds, by grams or by hand
Only two of the eight bring a scale with them. The Libra has the scale in the portafilter fork and switches off at the set gram value, accurate to plus/minus 0.2 grams according to Eureka. The Wilfa weighs beforehand: its lid is a removable scale, accurate to 0.1 grams according to Wilfa. You weigh the beans on it, tip them in, and the grinder runs until the hopper is empty.
Four control by time, with very different resolution. The Virtuoso+ sets 0.1 to 40.0 seconds in tenths of a second. The Sage stores its own duration for every shot and cup count, in steps of up to 0.2 seconds according to Sage. The Specialita has two programmable doses and a manual mode. The Opus has four fixed run times, 30, 60, 90 and 120 seconds, and for it the time is merely an upper limit, because the portion you put in is ground until nothing is left.
Two have no quantity control at all. The Encore ESP runs via a pulse button or the on/off button, the CM800 for as long as the portafilter presses against its contact switch.
This matters as soon as you change the bean. A timer repeats a time, not a mass, and how much ground coffee falls per second depends on the grind size. Baratza documents this itself for the Encore ESP: 1.3 grams per second at step 10, 2.2 grams at step 30. If you change the bean on a timer grinder, you weigh once afterwards and reset the time. For six of the eight, therefore, a scale belongs next to the grinder in our assessment, and the brew calculator works out the brew ratio for it.
Places one to eight and the reason for each
Place 1: Eureka Mignon Specialita, 9.4
The Eureka Mignon Specialita takes first place because of one detail of the adjustment. Eureka moves not the upper but the lower grinding disc and gives as the benefit maintenance without losing the setting you have found. Anyone who opens the upper burr carrier for cleaning does not, by our reading, start from scratch afterwards. On a stepless grinder without clicks, that is exactly the point where things otherwise snag. We would recommend it to someone who stands at the portafilter every morning and wants to hold a setting for weeks. It has no scale, the bean hopper holds 300 grams, and at approx. €431.90 it is the second most expensive grinder in the catalogue.
Place 2: Eureka Libra 16CR, 9.2
According to Eureka, the burr set of the Eureka Libra 16CR has the same characteristics as that of the Specialita. What it can do in addition sits in the fork: the portafilter rests there freely while grinding, a scale counts along, and it stops at the set gram value, selectable in tenths of a gram. That counts if you clamp in a different roast every week and would otherwise have to re-weigh the grinding time after every change. It still sits behind the Mignon Specialita because the extra cost of around €207 lies solely in the dosing. One catch is in the manual: a knock against the portafilter or fork pauses the process, and some disturbances are read by the grinder as removal of the portafilter, in which case the dose is lost. At approx. €639, none of the fourteen grinders in the category costs more.
Place 3: Wilfa Svart Uniform+, 9.1
Among the first four, the Wilfa Svart Uniform+ is the only one with a focus on pour-over. Its reason for being on the list is the sequence the manual prescribes: choose the grind size, weigh the beans on the lid, fill them in, start, and after the last bean the motor stops by itself. The lid scale has a stopwatch, and a short press on on/off tares and sets the time to zero at the same time. If you brew pour-over or AeroPress by the gram and do not yet own a coffee scale, you need no second device with it. As a daily espresso grinder we would not buy it, for the reason given above under the steps, and because it has no holder for the portafilter. Before buying you should also know that Wilfa listed it on its own site in September 2026 as sold out and now describes it as the predecessor of the Uniform Evo. The replacement burrs were available to order at the same time.
Place 4 and 5: Baratza Encore ESP and Baratza Virtuoso+, 9.0 each
Two grinders from the same maker with the same score, and according to Baratza with the same core: 40-millimetre cones made of M2, a high-speed steel, plus the same power, speed, hopper and outer dimensions. That the Baratza Encore ESP stands ahead of the Baratza Virtuoso+ is not a verdict. In a tie, our list framework sorts by file name.
What separates them is already laid out above: the ESP splits its scale and has no timer, the Virtuoso+ has the timer and no espresso zone. Then there is the fixing of the cone, on a quick-release clamp you loosen by hand on the ESP, on a thread on the Virtuoso+. The ESP comes with a dosing cup for 54-millimetre portafilters and an adapter ring for 58 millimetres; for the Virtuoso+, Baratza names the cup only as compatible. The Virtuoso+ costs €50 more.
In our assessment the ESP belongs with someone who pulls espresso in the morning, sets up a French press at the weekend and weighs the dose anyway. The Virtuoso+ suits someone who mostly brews filter or AeroPress and prefers to repeat the quantity by time. Their reviews give the ESP 8.9 for value for money and the Virtuoso+ 8.6; for handling it is exactly the other way round.
Place 6 and 7: Graef CM800 and Sage Smart Grinder Pro, 8.8 each
Here too, with equal points, only the name decides the order, although the two grinders are built in opposite ways. The Graef CM800 manages without a timer and without a scale. You set the switch to AUTO, press the portafilter against the contact switch on the holder, and it grinds until you pull it back; two holders of approx. 60 and approx. 70 millimetres are included. At approx. €139.99 it is the cheapest grinder on this list. We see it with someone who is looking for a grinder to go with a first portafilter machine, already owns a scale and wants to stay under €150.
The Sage Smart Grinder Pro relies on a display and stored times, and for that its review gives 9.0 for handling, against the Graef’s 8.3. For one to eight shots and one to twelve cups you store a separate duration each, and the switch from espresso to a pot costs one turn of the grind setting, one press on SHOTS / CUPS and pulling out the holder. Compared with the Graef CM800 you pay around €59 more, and on value for money the Graef leads with 8.6 against 8.2. Its bean hopper holds 450 grams, the largest as standard of the eight.
Place 8: Fellow Opus, 8.6
With the Fellow Opus, the manual itself advises against storing beans in the grinder, and the hopper holds 100 grams. What gets it onto the list is the switch between preparations: from espresso to pour-over it is one turn of the outer ring, from 1 to 2 to 5 to 9, and as long as the inner ring is left untouched, both remembered positions stay valid. It is for you if you weigh every portion beforehand and move between portafilter and pour-over, but do not dial in a new espresso bean every week. The cone has six cutting edges and turns at 350 revolutions per minute with 6 newton metres of torque.
How the eight differ
| Model | The difference | Price | Our score | Pick this if |
|---|---|---|---|---|
| Eureka Mignon Specialita | 55 mm flat burrs, stepless via the lower burr, dosing by time | approx. €431.90 | 9.4 | you pull almost only espresso and want to hold a setting for a long time |
| Eureka Libra 16CR | same burr characteristics, scale in the fork stops at the target weight | approx. €639 | 9.2 | you often change the roast and want to dose by gram without re-weighing |
| Wilfa Svart Uniform+ | 58 mm flat burrs, scale in the lid, grinds the weighed portion until empty | approx. €330 | 9.1 | you brew pour-over or AeroPress and do not yet have a coffee scale |
| Baratza Encore ESP | 40 steps, 1 to 20 fine for espresso, no timer | approx. €179.95 | 9.0 | you alternate between espresso and French press and weigh the dose |
| Baratza Virtuoso+ | same 40 mm cone, timer to the tenth of a second | approx. €229.95 | 9.0 | you mostly brew filter and repeat the quantity by time |
| Graef CM800 | contact switch instead of timer, fine adjustment only with a tool | approx. €139.99 | 8.8 | you want to spend little on a first portafilter machine and have a scale |
| Sage Smart Grinder Pro | own grinding time per shot and cup count, 60 steps | approx. €199.00 | 8.8 | you grind espresso on weekdays and a pot on Sundays |
| Fellow Opus | single dosing with a 100 g hopper, inner ring for intermediate values | approx. €230 | 8.6 | you weigh every portion and switch between portafilter and pour-over |
The prices are the guide values from our price boxes, the score is our assessment from data sheets and manuals. Whether one grinder grinds more evenly than another, this table cannot show, because none of us has checked that.
What you pay for between €139.99 and €639
For five of the eight, the reviews show the guide price as of September 2026. For the Libra and the Wilfa, the Amazon catalogue showed no price when retrieved on 7 September, both values are older, and the Libra’s value has stood unchanged since July 2026. For the Graef CM800, the catalogue showed €149.59 on that day.
At the bottom, the Graef CM800 stands alone at approx. €139.99. You get a conical burr set with 40 steps, a bean hopper for 350 grams and the contact switch; you determine the quantity by hand at the portafilter. In the Graef shop, the same grinder cost €189.99 on 25 September 2026.
In the middle, four conical grinders lie close together: Encore ESP, Smart Grinder Pro, Virtuoso+ and Opus. Between the cheapest and the most expensive of these four lie around €50, and for that money you do not buy a better grinder but a different way of dosing, from the split scale without a timer to single dosing. In the Baratza shop, the Encore ESP and Virtuoso+ cost the same as on Amazon; in the Sage shop, the Smart Grinder Pro stood at a regular €259.90 on 25 September.
At the top the paths part. From the Wilfa Svart Uniform+ to the Mignon Specialita it is €101.90, for which you change from a stepped grinder with a scale to a stepless espresso grinder with a fork, giving up the scale in the process. From the Mignon Specialita to the Libra 16CR comes another approx. €207, and from here on the extra cost, according to the manufacturer data, no longer buys a different burr set, only dosing by weight. The Libra thus costs around €499 more than the Graef CM800, a good four and a half times its price.
Which grinder suits which kitchen
Your portafilter is 51 millimetres. Then the dosing cups of the Encore ESP and the Opus are ruled out, both are built for 54 and 58 millimetres, and you grind into the catch container and transfer. The Smart Grinder Pro takes such a portafilter in its small holder for 50 to 54 millimetres. According to their manuals, the forks of the two Eureka fit all commercially available portafilters. For the Graef it stays open which of its two holders belongs with which basket; there we would ask customer service before buying.
The grinder has to fit under a wall cabinet. The Fellow Opus measures 26.8 centimetres according to the manufacturer and is thus the lowest of the seven for which a manufacturer figure exists. Then come the two Baratza at 34, the Specialita at 35, the Sage at 38.9, the Libra at 39 and the Graef at 39.7 centimetres. For the Wilfa there is only the catalogue figure from Amazon, and whether it refers to the device or the carton is unclear. Allow air above all of them, because lid and hopper come off upwards; with the optional 510-gram hopper the Libra grows to 43 centimetres.
You want to leave a week’s beans in the grinder. Then the Opus and Wilfa are out of the question: one holds 100 grams, the other takes up to 75 grams according to the Amazon catalogue. The Sage takes 450 grams, the Graef 350, the other four 300 each.
You are buying machine and grinder from one budget. Then we would not start with the Libra but put the money into the machine. The Smart Grinder Pro lies around €440 below the Libra 16CR, the Graef CM800 around €499.
You grind a large pot in one go in the morning. The grounds container of the Encore ESP holds 120 grams, and Baratza warns that grounds above the Max line can clog the burrs. With the Wilfa, 75 grams of hopper content at 60 grams of coffee per litre (not a Wilfa figure) is enough for a good 1.2 litres; beyond that you weigh and fill twice.
Care, dead space, throughput: what cannot be equated
None of these grinders lists a part as dishwasher-safe. Seven of the eight manuals expressly forbid the dishwasher, for individual parts or for all. The Graef manual says neither yes nor no; for the bean and grounds containers it provides warm water with a little washing-up liquid. The intervals cover a wide range. Graef provides, depending on use, for cleaning at least once a week, Baratza for brushing the burrs about once a month with daily use, Fellow for the cones of the Opus at least every three months. For the bean hopper of the Specialita and Libra, Eureka recommends hand washing at least once a week. The procedure in detail is explained in our guide on cleaning a coffee grinder.
Two quantities cannot be compared across the eight. The first is dead space, that is, the grounds that remain in the burrs. None of the manufacturers whose review asks about it gives a figure; Fellow speaks of low retention only for the Opus. The Virtuoso+ review does not ask for a quantity but cites Baratza’s note that partly ground beans can remain between the burrs after switching off. On the Wilfa this is especially a pity, because Wilfa writes that the European Coffee Brewing Centre examined exactly this residue.
The second is throughput in grams per second. Only Eureka and Baratza state it, and Eureka even twice: for the Specialita, the manual gives 1.4 to 1.8 grams per second in the espresso range, the product page the higher range of 1.8 to 2.5. Without throughput, the seconds of a timer cannot be translated into grams, and that affects precisely the Sage, which of all eight relies most on stored times.
Six reviews without a place, plus successors without a review
Six grinders in the category are missing here, all with scores below the average or exactly on it. These six reviews have also been revised; here we take from them only price, score and type of burr.
The Graef CM820 for approx. €157 has the same score of 8.6 as the Fellow Opus. That the Opus is here and the CM820 is not follows again from sorting by file name; which of the two we prefer is therefore not revealed by place eight. Like the Opus, the CM820 grinds with a cone, and it costs around €73 less.
Next come three more conical grinders and two with flat burrs. The Sage Dose Control Pro stands at approx. €153.25 and 8.4 points, the DeLonghi Dedica KG 520.M at approx. €131.89 and 8.2, the Rommelsbacher EKM 400 at approx. €87.99 and 8.0. With flat burrs follow the Rommelsbacher EKM 200 for approx. €54.99 with 7.8 points and the Caso Barista Crema for approx. €39.99 with 7.6, the cheapest grinder in the category.
Not in the catalogue are the successors and sister models mentioned in the reviews. Wilfa lists the Uniform Evo, Fellow sells the Opus 2 in the USA, Baratza has the ESP Pro above the Encore ESP, and of the Specialita sisters Compatto, UP and Smart, none is reviewed by us. Hand grinders are a category of their own with their own best hand grinders list; a general overview of the designs is given by the grinder guide.
