Eureka Mignon Libra review (2026)

Updated 2026-10-21 · Based on 8 cited sources.

Kaffeemacher calls it a clear buy for home espresso once a dosing funnel stops the mess. Catches: espresso only, 2.4 g retention, 79.8 dB, and a portafilter of 175 g or more to tare.

2 of 2 reviewers recommend it

Eureka Mignon Libra is an electric grinder that suits Espresso and Moka pot. From €553.80 delivered to Germany, prices vary by country.

What are the pros and cons of the Eureka Mignon Libra?

Pros

  • Tests show the built-in scale is easy to calibrate and delivers the target dose reliably.
  • Tests show 20.2 g in 10 seconds, which places it in the upper-middle speed range for home espresso grinders.
  • With a dosing funnel fitted, tests show the grounds land in the basket without spray, and the maker says a funnel now comes in the box.
  • A reviewer finds the 55 mm burrs give rounded, body-forward espresso that suits medium to dark roasts, the same in the cup as the Specialità.

  • A retailer's own test over ten grinds saw doses average about 0.1 g under target, with the worst miss 0.3 g under.

Cons

  • Without a dosing funnel, grounds scatter around the grinder base, and tapping the portafilter to settle them upsets the scale.
  • Tests show 2.4 g total retention, and the same test advises purging about 3 g after changing the grind size.
  • Tests show it needs at least 175 g on the fork to tare, so very light portafilters and dosing cups may not trigger the scale.
  • A reviewer would reach for a larger burr set for mostly light-roast shots, as the 55 mm set suits medium to darker roasts best.

Who it suits

Best for

  • Home espresso drinkers who want to dose by weight without a separate scale
  • Milk drinks and medium to dark roasts
  • Households or small pop-ups pulling several shots in a row

Skip if

  • You want one grinder for espresso and filter
  • You mostly brew light roasts
  • You want to grind without a portafilter or into a light dosing cup

What do owners say about the Eureka Mignon Libra?

  • FH message if the portafilter is not seated. Customers on a shop page say the display shows FH unless the portafilter sits exactly in the fork. One says it happened often at first, another that it works accurately once placed carefully.
  • Scatter and funnel workarounds. Kaffeemacher says a dosing funnel stops the spray. itsXris also uses one. Travelling Dippegucker found a third-party funnel unsettled the tare and kept a spoon at the outlet instead.
  • Bottomless portafilters sit poorly. Kaffeemacher says some bottomless portafilters do not sit securely on the fork. itsXris found a spouted portafilter worked better for a pop-up.
  • Some units arrive with faults. RoastAroma's summary of owner threads mentions loose screws and on/off switch problems out of the box on some units.
