Eureka Mignon Libra vs Mahlkönig EK43
Two grinders cross-shopped at the same money. The Mignon Libra turns 0–24 rotations; the EK43 is numbered 0–16.
Which to buy
Choose the
Mignon Libra if you…
- pull espresso — Eureka lists it for that, with a hand-adjustable fork
- want to grind by weight — to within ±0.2 g, Eureka says
- want a smaller grinder — 390 mm tall, 6.5 kg
Choose the
EK43 if you…
- brew filter as well — stepless from Turkish fine to coarse filter
- grind in volume — about 19–21 g a second from a 1,200 g hopper
- grind straight into retail bags — it has a bag clamp

Converting a setting
If a recipe quotes a setting for one of these grinders, read across for the equivalent on the other. Rows are spaced evenly by grind size, not by dial number — on a conical burr those are not the same thing.

The shape of each dial
Where the connectors bunch, that grinder’s dial is compressed and single steps count for more. Comparing the two shapes tells you which gives finer control, and where.
Eureka Mignon Libra
Mahlkönig EK43
Dialing in the Mignon Libra
The Mignon with an integrated scale, grinding by weight rather than time. The dial behaves like the rest of the Mignon range; what changes is dose repeatability, not grind character.
Dialing in the EK43
The grinder that changed what filter coffee was supposed to taste like, and still the reference for high-clarity brewing. Its very large flat burrs produce an unusually narrow particle distribution, which is why coffee ground on an EK often tastes cleaner at the same nominal setting than it does elsewhere. Stepless, so treat the numbers as targets.
