The Eureka Mignon Single Dose Pro is the new version of the popular Eureka Single Dose grinder. The first version was already a solid grinder in the single-dosing category, but it also had weaknesses – particularly with retention and usability. Now comes the Pro model. Whether the "Pro" also delivers in the cup, we've 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 500 to 1000 euro price range. Learn more in our article on the topic.
What's new? A first look
The most obvious change: the new, significantly larger grind adjustment wheel with counting function. One full rotation advances the revolution counter. This makes switching between filter and espresso much easier – and above all more reproducible. Anyone who regularly switches between recipes will be delighted. The tactile improvement of the grind adjustment wheel is noticeable – and actually functional.
The grinder has also been refined in detail: the lid sits more securely, the discharge has been improved, and there's now a new, tapered dosing cup with a rounded 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! The burrs in the new Single Dose Pro are held from the back with screws, no longer from the front. What sounds trivial changes a lot, and we'll keep coming back to it throughout the test report.

Retention: Less, but still not little enough
Eureka has improved on retention – at least on permanent retention. It's now at 0.2 g and reduced compared to the old version (previously 0.3–0.4 g permanent). For temporary retention, it's different: 0.7 g is realistic. That's not really good for a single-dosing grinder – even if it's a good value compared to grinders with bean hoppers.
Permanent retention improved because the upper burr is now screwed from the top – i.e., from the back. Really great! Additionally, a slot in the burr suspension was reduced.
In short: the residual grounds in the grinder are less, but not as minimal as you'd expect from the best single dosing class grinders. 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 out the coffee more effectively, since the side slot is closed and all the blowing force goes into the grinder.
Speed, noise, temperature
The grinder is fast. 18 g of 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. The temperature increase is also minimal: 32.4 °C on average after five shots – unproblematic for the aromas.
The noise level is 81.1 dB – not whisper-quiet, but in the middle range. Anyone with a massive work surface will hear less. On lighter furniture it vibrates noticeably.
Operation: Finally comfortable
The operation is a major plus for the Pro model. The new grind adjustment wheel with counting helps enormously with reproducibility. Returning to the old grind setting also works without problems.
We determine this by switching from the standard recipe (T4) to ristretto, then lungo (T6) and back to espresso. When resetting, we proceed purely visually by setting to a noted grind adjustment. We then measure the extraction time and also compare the particle distribution via laboratory 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 adjustment wheel, this is 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 attention – the 0.7 grams of coffee from retention are part of the output 18 grams!
The dosing aid reduces static losses, the dosing cup functions well and sits securely 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 powerful, 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 is very nicely executed here. 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 benefits greatly from the upper burr being screwed from the back. The grinder's main peak is much narrower than that of the previous version. We can grind really fine without losing clarity.
The fact that many burrs are mounted with screws through the burr is rarely discussed. Actually surprising, since otherwise every imperfection on a burr leads to a big drama and buying new burrs. But the screw holes have such a large impact on the overall 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. Above all, reproducibility and everyday practicality have been significantly increased. The reduced retention is a step in the right direction – but doesn't yet reach the level of the best single-dosing grinders.
The best thing about the new grinder is the upper burr screwed from the back, which leads to more uniform particle distribution and thus better espresso. Bravo Eureka, that's a good path! Now what about the other burr?!
If you have the first version, you don't necessarily have to upgrade – but if you're starting fresh, you get a very good grinder for a fair price. And: it looks incredibly good in coffee maker green. What else distinguishes the grinder: it's manufactured in Europe and spare part availability and repair options are ensured thanks to competent specialist workshops in Germany, Switzerland and Austria.
