Eureka makes so many grinders that even we sometimes lose track. Over 30 models, plus names like Silenzio, Perfetto, Specialità, Zero, Manuale or Libra, which differ sometimes significantly, sometimes hardly at all. On this page we compile everything we've tested on Eureka and organize it so you know in a few minutes which Eureka is right for you. We've purchased around a dozen Eureka grinders ourselves and tested them according to our full protocol: particle distribution in the lab with the ZHAW, retention, volume, grinding temperature and consistency. Eureka grinders have also been in constant use in our coffee academies in Basel and on the Lower Rhine for years.
History and Brand
Eureka is not a young brand. The company was founded in 1920 in Florence by Aurelio Conti, initially with electric mixing devices, and only after the war did coffee grinders and other kitchen appliances follow. For three generations, Eureka remained in family hands (Aurelio, then Valerio, then Filippo Conti). Today the company operates as Conti Valerio Srl based in Sesto Fiorentino near Florence, led by Maurizio Fiorani. Manufacturing is still largely based in Tuscany today, Eureka speaks of "Made in Florence" and hand assembly. Under one roof, the brands Eureka 1920 and the premium line Eureka ORO operate. In 2024, Eureka opened the "Mignon Factory," its own production facility exclusively for the Mignon series, the best-selling model in the prosumer segment.
Most Eureka grinders continue to be manufactured in Italy. Two affordable entry-level models have now become exceptions: Eureka has the Manuale and the new Zero 55 S manufactured in its own facility in China; all other models continue to come from Italy. We don't see any quality disadvantage in our measurements, but "Made in Florence" no longer applies across the board to the entire range.
First, sort out the names: Mignon, Oro and 1920
Much of the confusion with Eureka comes from the fact that two different things are contained in the name: the design and the line.
Mignon is the design. The compact, angular housing with the stepless grind setting adjustment on top has made Eureka the reference for home use. Almost all models on this page are Mignons. They primarily differ in dosing and equipment: Specialità and Magnifico with timer and display, Manuale with only an on/off switch, Libra with scale, Zero as the budget range.
1920 and Oro, on the other hand, are the two lines—that is, the quality and price levels. Eureka 1920 is the classic line with the 50- and 55-mm burrs, robust and fairly priced. Eureka Oro is the premium line: it brings the technology of larger grinders into the Mignon housing, meaning 65-mm burrs, often with Diamond Inside treatment, and for single-dosing models the tilted grinding chamber for virtually no residue. The Mignon XL is the entry point into the Oro line, which also includes the Single Dose Pro and the 65-mm models.
Mignon tells you how the grinder is built. Oro or 1920 tells you which league it plays in. A 65-mm burr and the tilted zero-retention chamber are almost always Oro features.

Which Eureka should you buy?
Instead of sorting by model name, we sort here by need. Find the case that fits you best.
Cheapest entry level, you mostly drink the same bean. The Mignon Manuale. It's loud and a bit finicky out of the box, but it has a surprisingly clean burr set. With a few upgrades (more on that below) it becomes an affordable single-dosing grinder.
Comfort with timer, one favorite blend in daily life. The Specialità or the Magnifico. Both are quiet and consistent. The Magnifico has more durable burrs and stays slightly cooler under load; otherwise they're very similar.
Honest answer: The smart features don't justify the extra cost in our test. The burr set is solid, but the digital grind display drifts and makes saved recipes unreliable. If you're going to ignore the smart functions anyway, go for the classic Specialità instead. Details in the Smart test.
Larger, quieter, more consistent. The Mignon XL with 65-mm burrs, or from the budget line the Zero 65.
Fresh bean switching, single dosing. The Single Dose Pro. It has the large grind dial with counter and, thanks to the rear-screwed burrs, a narrower main peak—thus clearer espresso.
Exact dosing at the push of a button, espresso and occasional filter. The Libra 65 All Purpose. The scale takes away the need to weigh afterwards, and beginners especially benefit enormously. One note: scale grinders are not designed for the single-dosing workflow with an empty hopper; they want a filled bean container to work precisely.
The small grind dial: the Eureka weakness and its solution
One point runs through almost all Mignon models: the tiny original grind dial. On the Manuale, Specialità and Magnifico, it's too small, jumps in too large increments and makes it almost impossible to return to a remembered recipe. With the Manuale, this bothered us so much that we replaced it.
The solution at Eureka is called "King Size": a larger dial with scaling that even counts rotations. On newer models (Single Dose Pro, Libra 65) it comes standard; on older ones it can be retrofitted. In combination with a single-dose bellows and a grind funnel, we turned the Manuale into a grinder that keeps up with dedicated single-dosing grinders in terms of retention.
- King-size grind dial: solves the precision problem of the original dial.
- Single-dose bellows: drastically reduces retention.
- Grind funnel: cleanly directs the grounds into the portafilter.
- Wood lid: our own replacement lid for the Mignon series.
Burrs: Diamond Inside and Black Diamond
There's a lot of marketing and some misunderstandings around Eureka's burrs. We separate the two things that are often confused. The coating (Diamond Inside, Black Diamond) makes the burrs more durable, but doesn't change the grind profile or taste. We've measured this multiple times. The geometry of the burr, on the other hand, significantly changes the cup: Eureka offers various geometries under Black Diamond (Italian Espresso Taste, Espresso Specialty, All Purpose) that range from body-forward to acid-forward and clear.
Which burr matches which grinder and taste, we've broken down separately with lab and cupping data: Eureka Black Diamond burrs in test.
Eureka with scale: Grind by weight
Eureka was one of the first manufacturers to bring the integrated scale to compact home grinders. Instead of dosing by time, the grinder stops when the target amount is reached in the portafilter. The Libra (55 mm) was the first attempt and works cleanly only with the dosing ring and is now only available in remaining stock (around 230 euros). The Libra 65 All Purpose does many things better: 65-mm burr set, king-size dial, magnetic dosing ring from the factory. Next comes the Eureka Tio, a grinder that communicates directly with a Quick Mill machine and adjusts the grind itself.
Common problems and repair
Two things come up repeatedly with Eureka grinders. First, many Mignons scatter grounds around the portafilter; a dosing ring helps. Second, and more serious: With the Specialità (and identical models with the same touch display) the timer or display fails in some users. The good news: this is most likely a firmware problem that can be fixed with a reset instead of replacing the display every time. We've documented exactly how it works here: Eureka Mignon touch display problem.
Distribution, specialty retailers and accessories
Eureka sells through specialty retail, not through aggressive direct sales. We work with selected specialty partners whom we know provide good service, including grinder readjustment:
- Germany: Stoll Espresso and Lücke
- Switzerland: Adrianos
- Austria: Bohnendealer
These are affiliate links: it won't cost you any more, and we put the commission toward new test equipment.

Frequently asked questions about Eureka grinders
Are Specialità and Zero the same? No. They are two different, parallel-sold models. The Specialità is the established espresso classic with bean hopper and timer; the Zero is its own, cheaper and more versatile range (also available as Zero 65 with larger burr set).
What's the difference between Magnifico and Specialità? Almost nothing. The Magnifico has burrs treated with Diamond Inside (longer durability) and stays slightly cooler under continuous load. In everyday use, this has no measurable effect on particle distribution and taste.
Are Eureka grinders built in Italy or China? Eureka still manufactures most models in Italy. Only two cheap entry-level models, the Manuale and the Zero 55 S, now come from a Eureka facility in China. We could not detect any quality difference in our measurements.
Do Black Diamond burrs make better coffee? The coating doesn't; it just extends durability. The different geometries do—they significantly change the character. More on that in the burr comparison.
Is the king-size grind dial worth it? Definitely for older Mignons with the tiny original dial. It makes grind setting precise and reproducible.
Which Eureka has a scale? The Libra (55 mm) and the Libra 65 All Purpose (65 mm). For the classic Libra we recommend the dosing ring.
My Eureka display is glitchy, what do I do? Usually a firmware problem that can be fixed with a reset. See touch display problem.
And models like Silenzio, Perfetto or Oro? Many of them are variants of the tested Mignon grinders. The Silenzio is a sound-dampened variant, the Perfetto a timer grinder close to the Specialità, and Oro is not a single grinder but Eureka's premium line, which includes for example the XL and the Single Dose. For most, the path leads through the models tested here.
Conclusion
Eureka's range looks confusing, but behind the facade is a manageable system of just a few burr sets (50, 55 and 65 mm), combined with timer, scale or single-dose design. For most at home, the Specialità or Magnifico is the solid timer solution, the Single Dose Pro the best choice for fresh single portions, and the Libra 65 All Purpose the convenient all-rounder with scale. The Manuale is the budget bargain if you're willing to get your hands dirty yourself. And almost everywhere this applies: the tiny original grind dial is the weakness, the king-size dial is the answer.
