Home espresso enthusiasts who want café-quality flat-burr grinding without café prices
Buy on Amazon →This is the cleanest comparison on the site, because almost everything is held constant. Eureka Mignon Specialita and Eureka Mignon Libra share the Mignon platform and the same 55 mm flat burrs. What Eureka Mignon Libra adds is a scale inside the grinder, so it doses by weight rather than by time — and whether that is worth the difference comes down to a single habit.

The short answer
Buy the Eureka Mignon Libra if you weigh every dose today and want to stop. Grind-by-weight removes the scale from your workflow without removing the accuracy, and our record marks it best for shot-repeatable espresso workflows that want dose-by-weight without a separate scale.
Buy the Eureka Mignon Specialita if you do not weigh doses, or you are happy to keep a scale on the counter. You get the same burrs for meaningfully less. Our record marks it best for home espresso enthusiasts who want café-quality flat-burr grinding without café prices.
How we can say this: both grinders went through the same published evaluation against the same rubric, and each one's full record is on its review page. That is a repeatable, documented comparison; it is not a taste test, and we say so wherever it matters.

Which one should you buy?
Every row below is resolved from the two catalog records, not from a preference of ours; where the records tie, the row says so.
| If what matters most to you is… | Then | Because |
|---|---|---|
| Spending the least | Eureka Mignon Specialita | Same burrs, same platform — the gap is the scale. |
| Dosing by weight | Eureka Mignon Libra | The one feature that separates them, and the whole argument for the dearer grinder. |
| Stepless adjustment | Either — the records tie | Both micro-adjust continuously; neither gives that up. |
| The largest burrs | Either — the records tie | They share a burr size, so this one ties — which is the point of the comparison. |
| The smallest footprint | Eureka Mignon Specialita | Both are Mignon-bodied and tight on the counter. |
| The quietest kitchen | Eureka Mignon Libra | Manufacturer figures, listed below. |
| A longer warranty | Eureka Mignon Specialita | Weigh it alongside the price gap. |

The price difference, and what it buys
| Grinder | What it is | Price |
|---|---|---|
| Eureka Mignon Specialita | Flat Burr · 55 mm · Timed | $549 |
| Eureka Mignon Libra | Flat Burr · 55 mm · Grind-by-weight (integrated scale) | $799 |
| Difference | $250 | |
The gap buys a scale you do not have to look at. That is worth a great deal to someone who weighs every dose and nothing at all to someone who does not — which makes this one of the few comparisons where the right answer is genuinely a fact about you rather than about the grinders.
What grind-by-weight actually removes
Every accurate espresso workflow weighs the dose. The usual way is a scale on the counter: tare the portafilter, grind, check, adjust, brew. It works and it is cheap.
Eureka Mignon Libra moves that scale inside the grinder. You ask for a dose in grams and it grinds until it has delivered that, which removes a step and a gadget from the bench.
What it does not do is make the coffee better. The shot is the same shot; the difference is how much attention it took to get there. Our record marks Eureka Mignon Libra as best for shot-repeatable workflows that want dose-by-weight without a separate scale — which is a precise description of who should pay the difference.
What the two share, which is nearly everything else
Both run 55 mm flat burrs on the same Mignon body, both adjust steplessly, and both are built for the same counter. The spec table below is unusually boring for a comparison page, and that is the useful finding: there is no hidden second difference lurking behind the headline one.
So if you have decided against grind-by-weight, you are not giving anything up by taking Eureka Mignon Specialita. You are buying the same grinder without the scale.

Buy on Amazon →Frequently asked questions
Is the Eureka Libra worth the extra over the Specialita?
Only if you weigh every dose today. The Libra adds a scale inside the grinder so it doses by weight instead of time; everything else — the 55 mm flat burrs, the stepless adjustment, the body — is shared. If a scale on your counter does not bother you, the Specialita is the same grinder for meaningfully less.
What is the difference between the Specialita and the Libra?
One feature. The Libra doses by weight using a built-in scale; the Specialita doses by time. They share the burr size, the burr type, the stepless adjustment and the Mignon body, which is why the spec table on this page is so nearly identical.
Does grind-by-weight make better espresso?
No. It makes the same espresso with less attention. Dose accuracy matters for repeatability, and weighing achieves it either way — the Libra just does the weighing for you. The cup is decided by the coffee, the recipe and the machine.
Do both grinders use the same burrs?
They share a burr size and type according to our catalog records, which the spec table on this page lists side by side. That is the reason this comparison comes down to dosing rather than grind quality.
Which Mignon should I buy if I only drink espresso?
Either, on grind terms. The question is whether you want the dose weighed for you. Both are aimed at home espresso and both are stepless, which is what dialling in wants.
