The Eureka Mignon Single Dose Pro is the new version of the popular Eureka Single Dose grinder. Even the first version was a solid grinder in the single-dosing category, but it also had weaknesses – particularly regarding retention and usability. Now comes the Pro model. Whether the "Pro" also comes through in the cup, we tested – as always with our full test protocol and a critical eye on what improved, what stayed the same, and where there's still room for improvement.
We compared 10 single dosing grinders in the price range of 500 to 1000 euros. Read more about it in our article on the subject.
What's new? A first look
The most obvious change: the new, much larger grind setting dial with counting function. One full rotation increments the rotation counter. This makes switching between filter and espresso much easier – and above all, more reproducible. If you regularly switch between recipes, you'll really appreciate this. The tactile improvement of the grind setting dial is noticeable – and actually functional.
The grinder was also refined in detail: the lid sits more stably, the discharge was improved, and there's now a new, tapered dosing cup with a bulbous base area that sits better on the portafilter – and actually does so without distributing statically charged coffee dust around the kitchen.
But the most important change is inside the grinder! On the new Single Dose Pro, the burrs are held from the back with screws, no longer from the front. What sounds trivial changes a lot, and we'll come back to it again and again in the test report.
Recommended specialty retailers for the Eureka Single Dose Pro
We search for specialist partners for you, partners we know do good work and provide good service. We maintain close contact with these retailers. These are commission links. If you order through these links, it doesn't cost you any more, but we receive a small commission that we invest in new test equipment.
Retention: Less, but still not little enough
Eureka has improved retention – at least when it comes to permanent retention. It now sits at 0.2 g and is reduced compared to the old version (previously 0.3–0.4 g permanent). Temporary retention is a different story: 0.7 g is realistic. That's not really good for a single-dosing grinder – even though it's a good value compared to grinders with bean hoppers.
The permanent retention improved because the upper burr is now screwed from above – i.e., from the back. Really great! Additionally, a slot in the burr suspension was made smaller.
In short: residue in the grinder is less, but not as low as you'd expect from the best grinders in the single dosing category. At least: static charge is low, RDT is not necessary.
Speaking of temporary retention: if you push the slider on the bean hopper into the grinder, the grinder blows the coffee out more effectively, since the side slot is closed and thus all the blowing force goes into the grinder.
Speed, Noise, Temperature
The grinder is fast. 18 g espresso is ground through in about 11 seconds. With a full bean hopper, the Single Dose Pro manages 28 g in 10 seconds. That's impressive for such a compact grinder. Temperature rise is also kept in check: 32.4 °C on average after five pulls – unproblematic for the flavors.
The noise level is 81.1 dB – not whisper quiet, but in the midrange. If you have a massive work surface, you'll hear less. On lighter furniture, vibration is noticeable.
Usability: Finally comfortable
Usability is a major plus with the Pro model. The new grind setting dial with counting helps enormously with reproducibility. Returning to the old grind setting is also straightforward.
We determine this by adjusting from the standard recipe (T4) to ristretto, then lungo (T6), and back to the espresso. When resetting, we proceed purely visually by going to a noted grind setting. We then measure extraction time and also compare particle distribution via lab measurement.
A look at the particle distribution helps assess reproducibility. The fine peak changed from 30.2 % to 30.5 %, the main peak from 200.5 to 203.2 microns. That's almost no difference at all and an outstandingly good value. With the new grind setting dial, a real strength of the grinder!
When you input 18 grams of coffee, you get 17.9 or 18 grams back out of the grinder. The standard deviation here without RDT was only 0.044 g. But be careful – the 0.7 grams of coffee from the retention are part of the 18 grams dispensed!
The dosing aid reduces static loss, the dosing cup works well and sits stably on the portafilter.
A real update compared to the old version: something has changed here – and you notice it in everyday use.
Taste: Dark Chocolate Meets Clarity
The espresso from the Pro version is full-bodied, with notes of dark chocolate, marzipan, and cocoa. The body is medium, the texture silky-creamy. The grinder brings clarity to the cup without losing depth. That's a combination that rarely succeeds – and here it's been implemented very nicely. We tasted our Apas espresso, which we frequently use in grinder and machine tests.
The particle distribution curves show what we taste: a clear, dense main peak with good reproducibility.
The new Eureka Single Dose Pro does very well with the upper burr screwed from the back. The grinder's main peak is much narrower than that of the previous version. We can really go fine without losing clarity.
The fact that many burrs are attached with screws running through the burr is rarely discussed. Actually quite surprising, since otherwise every blemish on a burr becomes a big drama and necessitates buying new burrs. Yet the screw openings have such a huge impact on the entire grinder geometry. This becomes obvious when you see the old particle distribution curve next to the new one.
Conclusion: Good grinder gets better
The Eureka Mignon Single Dose Pro is a successful update. The improvements aren't spectacular, but they're well thought out. Reproducibility and everyday practicality have been significantly improved. The reduced retention is a step in the right direction – but it doesn't quite reach the level of the best single-dosing grinders yet.
The best thing about the new grinder is the burr screwed from the back, which results in more uniform particle distribution and thus better espresso. Well done Eureka, that's a good direction! Now for the other burr too?!
If you have the first version, you don't necessarily need to upgrade – but if you're just getting started, you get a very good grinder for a fair price here. And: it looks damn good in coffee maker green. What also distinguishes the grinder: it's manufactured in Europe, and spare parts availability and repair options are ensured thanks to competent specialist workshops in Germany, Switzerland, and Austria.
