Eureka Mignon Libra Espresso Grinder, Grind by Weight
Guaranteed Safe Checkout
Eureka Mignon Libra espresso grinder55 mm flat burrs and a weighing system that stops at your dose.
The Eureka Mignon Libra is an electric espresso grinder that weighs the coffee as it grinds into your portafilter and stops at the dose you programmed, consistent to ±0.2 g. Inside are 55 mm hardened steel flat burrs, a stepless micrometric grind adjustment and a 300 g bean hopper. It is built for home baristas who pull espresso every day and want the same dose in the basket without weighing each one on a separate scale. Available in White, Black and Chrome.

- Stepless micrometric grind
- White, Black or Chrome
Grams or seconds
A timed grinder
- It runs for a set number of seconds, so the grams drift when the beans, the roast or the hopper level change
- You weigh every dose on a scale, then top up or scoop out
- A dose that is a little off changes how fast the shot runs
The Mignon Libra
- It weighs the grounds going into the portafilter in real time
- It stops at your target, consistent to ±0.2 g
- Pull the portafilter mid-grind and the motor stops at once
Move the grind finer or coarser and the dose stays where you set it, because the target is grams, not seconds. Dialing in becomes one variable at a time.
Three numbers for a home bar
How a dose works
-
Set the fork
The adjustable fork holds the portafilter hands-free. Eureka designed it to fit any portafilter, 58 mm included, and you set it by hand with no tools.
-
Program two doses
The touch display stores two dose programs plus continuous grinding, for example your single and your double.
-
Grind
Press once. The Libra weighs as it grinds and stops at the target. The ACE system cuts clumps and static so the grounds fall evenly.
-
Adjust
The stepless micrometric collar moves in any increment, not fixed steps. Change the grind; the dose weight holds.
Who it is for
The Libra fits if
- You pull espresso every day and want the scale out of the workflow.
- Two people share one machine and each wants the same dose with one press.
- You want a quiet morning. Eureka builds the Libra with its Silent Technology.
- Your counter has 39 cm (15.4 in) of height under the cabinets.
Look elsewhere if
- You brew mostly pour-over or want a grinder that travels. The 1Zpresso K-Ultra is a hand grinder that folds into a bag and covers pour-over to espresso.
- You want filter coffee first. Eureka lists espresso as this model's recommended use.
The numbers
Answered plainly
Does the Libra really grind by weight?
Yes. Eureka's Instant Grind Weighing Technology weighs the ground coffee landing in the portafilter while it grinds and stops the motor at your target. The weighing system is calibrated at the factory, so it is ready to use out of the box.
Will it hold my portafilter?
Yes. The fork adjusts by hand, with no tools, and Eureka designed it to fit any portafilter, 58 mm included. Set it once and the portafilter sits under the chute hands-free.
Can I grind for pour-over too?
It will grind coarser, but this model is set up for espresso, which is the use Eureka recommends for its burrs. If your mornings are mostly pour-over, a hand grinder such as the K-Ultra is the better match.
What happens if I pull the portafilter out mid-grind?
The grinder stops immediately. Eureka built that stop into the weighing system, so a bumped portafilter does not keep the motor running.
