Eureka Mignon Libra Espresso Coffee Grinder
Since we brought in the Eureka line of espresso coffee grinders back in 2015, we have seen many different models over the years. Each one has something unique to offer. The Atom Specialty 65 can handle large-volume grinding. The Perfetto can grind for multiple brew methods. Now we are excited to introduce this new grinder with a feature that you don't find in other grinders. The Eureka Mignon Libra features grind-by-weight dosing. Most on-demand grinders are timed based in that the grinder will run for a preset time. As you refill your hopper with beans that may have a slightly lighter or darker roast, that can affect how much coffee will fill your portafilter. This may require recalibrating your grind time. With the Eureka Mignon Libra, you select the exact amount of ground coffee you need (in grams) and it will grind out that amount. Lessens the need to readjust and is accurate within +/- 0.2 g to reduce waste.
On Demand Grinding
- Grind by Weight Dosing! One of the few espresso coffee grinders on the market with this feature! Most on-demand grinders are timed based in that the grinder will run for a preset time. As you refill your hopper with beans that may have a slightly lighter or darker roast, that can affect how much coffee will fill your portafilter. This may require recalibrating your grind time. With the Eureka Mignon Libra, you select the exact amount of ground coffee you need (in grams) and it will grind out that amount. Lessens the need to readjust and is accurate within +/- 0.2 g to reduce waste.
Flat Grinding Burrs
- Flat burrs – Large size at 55 mm. The larger the size, the more of a grinding surface, resulting in faster production.
- Easy access – Remove the bean hopper. Behind the back logo, there is a Philips head screw that holds the top panel. Under the panel, there are 2 more Philips head screws that hold the top burr carrier.
- High rpm – Fast spinning rate at 1350 rpm. The higher the speed, the faster the production, which can increase efficiency and reduce wait times.
- Silent Technology – This built-in anti-vibration innovation solution helps reduce the grinding noise by ~20 dB resulting in a happier home and a more productive workspace.
- Reduce waste – Fits easily on almost every portafilter (57mm or 58mm). Helps reduce any spillage that may happen during the grinding process.
- Stepless – Infinite number of grind settings which allows you really fine-tune your grind. The adjustment dial is located underneath the hopper. The entire dial is numbered so you can remember your current grind setting easier. Turn clockwise for a finer grind and counterclockwise for a coarser grind.
Adjustable Portafilter Fork
- Ease of use – Allows you to rest your portafilter while grinding for a complete hands-free operation. Accommodates most portafilters.
- Adjustable – Accommodates almost any portafilter including the dosing funnel. The distance can be easily adjusted from 1″ to 2.5″.
- Top coating – The top of the fork has a silicone surface to prevent it from scratching the portafilter.
- Low profile – The total height of the Eureka Mignon libra without the hopper is a little under 11.5″ (to the grinding adjustment knob). The bean hopper adds another 4.25″ bringing the total height to approximately 15.375″. The total capacity is approximately 300 grams of whole coffee beans.
- Set screw – Secures the hopper to the grinder. Serves as a reminder for users to make sure the hopper is empty before removing it.
- Finger guard – Prevents users from “accidentally” putting their fingers in the grinding burrs. Also helps reduce
- Stopper – A door near the bottom of the hopper can slide in to close the opening. This allows you to remove the hopper with beans inside so you can easily change the beans. There will be some beans in the burrs which you will have to grind out first before removing the hopper.

Espresso Coffee Grinder Warnings:
- Changing grind settings: It is very important to only change grind settings when the unit is powered on and the burrs are in motion. If you do not do this, the burrs will ‘gunk’ up and render the grinder to only produce very coarse grinds or no grinds at all. To remedy this, you will have to open up the grinder to get access to the grinding burrs. This issue will be considered operator error for lack of following directions, and not be classified as a defective grinder.
- Electrical cord: For most grinders, the cord is placed between the packaging (foam or cardboard) and the underside body of the grinder. During shipping, it is normal for a bend or insignificant blemish/slice to damage the cord.
- Finding coffee grinds in a new grinder: Most manufacturers test their grinders with coffee beans before they leave their facility. Unfortunately, they are not always able to get every trace of coffee out of the grinders after testing. As a result, you may find coffee beans or grinds inside your grinder, or there may be grinds in the packaging.
- Static issues: There are static issues with all grinders, even the highest-quality models. We firmly believe that the static comes from the coffee beans. If you are having static problems with your coffee grinder, try using a different blend of beans.
- Electrical: To avoid electrical damage (which is not considered a manufacturer’s defect), please acquire and install a single-outlet surge suppressor rated at 1080 joules or higher. A surge without protection can damage a grinder at the power switch, the capacitor, the motor, or the wiring.
- Burr cleaning: For routine maintenance of the grinding burrs, we recommend using grinder cleaning agents. We do not recommend any removal of the burrs or the burr carrier for cleaning (unless necessary) as re-assembly can cause damage.
- Replacing burrs: NEVER use a flathead screwdriver and hammer to wedge under the burrs for removal. This could badly damage your grinder.
