Eureka Mignon Manuale Test: Budget-Friendly Espresso Entry and Hidden Gem with Upgrades
Eureka's product range is often as opaque as a poorly extracted espresso. There's the Silenzio, the Specialita, the Perfetto – and at the very bottom of the price hierarchy sits the Eureka Mignon Manuale. With a street price of around 240 francs (or euros), it's the cheapest entry ticket into the world of Italian traditional grinders.
The grinder was developed at a time when single dosing wasn't yet a topic for the mass market. Actually, mechanically it works exactly like such a grinder: it has an on and off switch – and that's it. No programmable time, no portions. Modern single dosing grinders work exactly the same way, only they've been further optimized, especially to reduce retention.
Retention is the area of a grinder that fills with ground coffee residue that isn't directly dispensed during brewing. Without optimization, we measure around 3 grams of retention on the Manuale. That's quite typical for an old-school "dosing grinder." However, if we perform optimizations ourselves, this value drops significantly.
This is why this test report is also a guide on how to turn the classic Mignon Manuale into a budget single dosing grinder with Eureka quality. Why is it worth it? Because the particle distribution and espresso quality absolutely speak in favor of this grinder!
Working Classically with the Mignon Manuale
Without time-controlled dosing and with a simple bean hopper, many of the cheaper espresso grinders were equipped when "grinding on demand" became popular both at home and in gastronomy. Instead of a dosing chamber, coffee is ground directly into the portafilter. Home baristas used to control the amount dispensed often by eye. A few weighed the dispensed amount.
Since the dispensed amount is crucial for maintaining the brewing recipe, we teach strict weighing in our home barista courses. This works quite easily with the Eureka Mignon Manuale: we position a scale in front of the grinder and grind directly into a dosing container that sits on the scale. When the target amount is reached – let's say 18 grams of coffee for a double espresso – we stop the grinding manually.
From the dosing container, the coffee is transferred to the portafilter, tamped, and then the espresso is pulled.
Feel: The Solid Eureka Base
A Eureka is, in almost every price range, a Eureka. And yes, the Mignon series with its solid, milled aluminum body hardly differs from the Manuale to the expensive Oro XL in basic quality.
However, the Manuale unfortunately comes with the small, tiny, and repeatedly criticized mini grind adjustment wheel. If you only want to make one upgrade to the grinder, make it this one: swap the wheel for a larger one. Precise espresso adjustment is otherwise virtually impossible. The larger the diameter, the more precisely the adjustment can be controlled and, above all, noted.
The adjustment is basically stepless. However, you only notice this with a different wheel. If you set the grind with the small original wheel, you automatically keep jumping in larger increments. There's no orientation whatsoever, and returning to a previous recipe is simply impossible.
Otherwise, the Manuale has the aforementioned on/off switch, 50 mm flat parallel burrs, and a bean hopper with a capacity of around 300 grams. One detail is annoying in daily use: if you push the slider in and remove the hopper, about 11.5 grams of coffee remain in the chute, which would have to be laboriously removed before switching beans.
The Mignon Manuale is 35 cm tall, 14 cm deep (with plug 16 cm), 12 cm wide, and weighs 5.6 kilograms. The burrs rotate at a fixed speed of 1350 revolutions per minute.
In Operation: Not for Sensitive Ears
Before we talk about the quality of the ground coffee, we need to discuss the noise level. The name "Silenzio" for the more expensive models doesn't come by chance, because the Manuale doesn't have any of the sound dampening installed in those. In our test, we measure a proud 86.6 decibels. That's loud. Really loud. For comparison: the dampened Specialita is more in the 78 decibel range. If you want to make espresso in the morning without waking the whole house, you won't find friends with the Manuale.
The grinding speed is also rather leisurely. For 18 grams of espresso beans, the grinder needs about 17.4 seconds. Without countermeasures, the grinder also scatters considerably, and the coffee grounds don't just land in the portafilter but also happily scatter onto the work surface due to static charge.
The Lab: Surprising Inner Values
We took the grinder apart and measured it. Inside, 50-millimeter hardened steel burrs work, classically bolted through by the grinding burr. A critical point for any grinder is the retention. When we use the grinder with the standard bean hopper, it retains approximately 3.2 grams of coffee grounds inside in total. That's relatively little for a dosing grinder, but in the age of single dosing quite a lot – especially if you want to use the grinder that way.
For example, if we put 18 grams of coffee into the empty grinder, we lose up to 2.4 grams in what's called exchangeable retention. The permanent retention, which practically never sees daylight, comprises another 0.8 grams.
The Particle Distribution: The Secret Star
We had the ground coffee from the Manuale measured in collaboration with ZHAW (Zurich University of Teacher Education). In this standardized measurement procedure, which we've already conducted on over 90 grinders, the small 50mm burrs show a surprisingly homogeneous picture.
We arrive at a main peak of 200.8 microns, which is very narrow and good. Many particles are similarly sized and are therefore extracted uniformly. In contrast is a rather higher fine peak, meaning fine particles that create good resistance in the portafilter (puck).
Interestingly, the budget Manuale grinds here "cleaner" and with a narrower peak than, for example, a Niche Zero, which costs significantly more. So the grinding mechanism delivers a quality that far exceeds what the price would suggest. That's a real statement to the competition.
The Upgrade: From Beginner to Single Dosing Expert
The good particle distribution invites further optimization of the grinder – and thanks to many available third-party additions, this is possible. We ourselves have identified the three most sensible upgrades:
- The larger grind adjustment wheel ("King Size")
- The single dosing bellows hopper
- Better guidance for the ground coffee (funnel)
Since we were bothered by the small adjustment wheel and the retention, we modified it. First, we replaced the tiny original wheel with a larger one that Eureka itself calls the "King Size" wheel. This finally allows the grind to be set delicately and precisely.
The real breakthrough is converting to single dosing. We removed the standard hopper and replaced it with a bellows attachment. Now, when you operate the bellows toward the end of the grinding process, you actively push the coffee residue out of the grinding chamber.
The lab results are impressive: the retention reduces to 0.1 to 0.2 grams. Suddenly, the 240-franc grinder is playing in the same league as dedicated single dosing grinders, which often cost double or triple. Whoever performs this small conversion significantly upgrades the machine.
The small attachable discharge funnel also ensures that the ground coffee lands better in the dosing container. Yes, such a thing is also a worthwhile investment, as is a small scale for weighing the coffee powder amount.
Taste in the Cup
Measurements are important, but does the espresso also taste good? We've tasted various roasts, including our dark Apas and medium roasts. Since the particle distribution is very homogeneous, we achieve espressos with nice texture and a round body.
The grinder is excellent for classic, dark to medium roasts. Here it really shines and delivers results that are hardly distinguishable from significantly more expensive grinders.
However, anyone primarily drinking very light, fruity roasts might hit some limits. We often couldn't set the grinder fine enough – lighter roasts require an even finer grind to develop sufficient resistance in the portafilter. In our experiments, we even heard the burrs grinding against each other before the espresso flowed slowly enough. This is nothing for light roast lovers. So we switched back to medium roasts like the Toca or Apas, where the grinder shines.
Conclusion: The Best Grinder Under 300 Francs?
The Eureka Mignon Manuale is a fascinating device. Out of the box, it's loud and somewhat awkward to operate. But at its heart – in the grinding mechanism and motor – good Eureka quality awaits.
The grind adjustment in the basic version is challenging, which can be solved by upgrading the adjustment wheel. Then it's also possible to switch reproducibly between recipes and coffees. The grinding speed is slow, and to thoroughly clean the grinder (cleaning), you first have to loosen a few screws. That's impractical.
And yet: especially the espresso in the cup impresses thanks to very good grind homogeneity. And that's why the Eureka Mignon Manuale is an interesting grinder that – especially as a single dosing grinder with some upgrades – offers a very exciting entry into the world of espresso.
We think that with the right upgrades, the grinder doesn't have to hide behind hyped models like the Varia VS3 or the DF54. You just have to get your hands dirty yourself, but then the grinder is fun and makes damn good coffee!
