Description

With the latest entry into their enduring Mignon line of grinders, Eureka asked themselves, “how can we possibly revolutionize home espresso again?” “Is it even possible?” Folks, the survey is in, and the answer is a resounding, heck yes. Why grind by time when you can grind by weight? Coffee will never be the same. Sure, other grinders in the ether can, technically, grind by weight, but none with the precision and beauty of the Eureka Mignon Libra.

*Includes the Mignon Libra 58mm Dosing Funnel. 53mm needs to be purchased separately.

Need to Know

The Eureka Mignon Libra brings professional grind-by-weight precision into your home kitchen without the complexity of commercial equipment. Built around 55mm flat hardened stainless steel burrs and a 310-watt motor, the Libra grinds directly into your portafilter with remarkable accuracy — consistent within ±0.2 grams, shot after shot. The adjustable portafilter rest accommodates any basket size, and Eureka's anti-vibration system keeps the grinding process stable even if you bump the machine mid-dose. At just 64 decibels, it's one of the quieter grinders in its class — ideal for early mornings when the household is still asleep.

This is a grinder for the espresso enthusiast who's tired of guessing. No more tapping beans into a portafilter and hoping you nailed the dose. No more wasted coffee from over-grinding. The Libra weighs as it grinds, stopping precisely when your target is reached. It's the kind of tool that removes variables and lets you focus on technique, temperature, and taste.

Key Features

  • Grind-by-Weight Technology: Set your dose in grams and let the Libra stop automatically. Accuracy within ±0.2g means consistency you can taste.
  • 55mm Flat Burrs: Hardened stainless steel burrs deliver uniform particle distribution for balanced extractions and clean flavor clarity.
  • Stepless Micrometric Adjustment: Dial in espresso with infinite grind size control — no preset detents, just smooth, continuous adjustment.
  • Programmable Settings: Save multiple dose presets for different coffees or brew methods. Switch between profiles without resetting every time.
  • Anti-Vibration System: Eureka's patented design dampens motor vibration, keeping the grind stable and reducing noise to around 64 dB.
  • Adjustable Portafilter Rest: Accommodates spouted, bottomless, and oversized portafilters. Hands-free grinding with zero awkward balancing.
  • Compact Footprint: Fits comfortably on most countertops without dominating your workspace. Premium build quality in a thoughtfully sized package.

Ideal For

The Eureka Mignon Libra is perfect for the intermediate home barista who's ready to eliminate dosing guesswork and focus on extraction quality. If you've been eyeballing doses or using a separate scale, the Libra streamlines your workflow and tightens your consistency. It's also ideal for households where multiple people make espresso — everyone can save their preferred dose and grind size without recalibrating every morning. At $799, it sits in the sweet spot between entry-level grinders and high-end single-dosers, delivering grind-by-weight precision without the four-figure price tag.

Whether you're pulling straight espresso or dialing in for milk drinks, the Libra gives you the control and repeatability that separates good shots from great ones. And with Clive behind you, you'll get there faster.

Frequently Asked Questions

Reviews

Customers praised this grinder's accuracy, consistency, and quiet operation. "Great fluffy grounds" with precise grind-by-weight feature streamlines workflow. Some noted the adjustment knob is overly sensitive, requiring aftermarket solutions. Minor quality issues included scratched aluminum parts and uncalibrated units. Overall highly recommended despite calibration needs.

  • It is consistent and very accurate. I love that it removes the step of weighing my beans.
  • Great fluffy grounds. Has a nice smooth taste with clarity. Makes workflow so much faster.
  • The built-in scale makes fine-tuning a breeze, and the funnel helps keep my station tidy.

This is a big step up from our Baratza Encore.
One gripe...I got a larger grind adjustment knob, and while trying to install it, ended up having to disassemble the grinder to get the rod thing threaded again. Eureka should have a better design for that part of the grinder.

Great machine. So far its met my expectations. The only gripe i had, was that the grinder isn’t calibrated from the factory. Unless i missed that information in the instructions that it needs to calibrated out of the box. Regardless im very happy with my grinder. I would recommend this product!

Broken out of the box

Well this came broken out of the box. The LED screen has missing segments so we can't really tell whether we are dialed into say 18 g or 10 g. Also it's tricky to run in continuous or manual grind mode or maybe just not intuitive. It took us a really long time and call into Clive to figure out how to set the unit to zero and get the burrs to touch before using it our first time. Huge disappointment though receiving a broken grinder right out of the box.

Incredibly happy with my grinder and Clive Coffee

I love the Eureka Mignon Libra grinder. It is consistent and very accurate. I love that it removes the step of weighing my beans on a separate scale. To note, I do spot check the weigh by grind function occasionally to ensure its accuracy and it has been spot on every time. Additionally, I can not say enough great things about Clive Coffe. Their entire team is wonderful. They are very knowledgeable about all the items that they sale and incredibly responsive when I have any questions. I live in Texas and they make you feel like they are down the street instead of accross the country with how fast and efficient they are with their custom support. I will only use them for all my espresso needs.

It's a good grinder and

It's a good grinder and produces accurate grind by weight performance.

Unfortunately, the grind size adjustment knob is far too sensitive making it difficult to adjust (without over or under shooting) the desired grind size. This is time consuming and wasteful. each time I start a new bag of beans, I have to go thru this dialing in process, due to the slight variances of roast and coffee age.

I have two Eureka Mignon Specialita's and two Mignon Libra Espresso Grinders. They all suffer from this same problem.

In the past, I have purchased three aftermarket grind adjustment solutions which are made specifically for the Eureka grinders due to this known problem. It is available for $31. 99 before tax and shipping on Amazon under the description: ARO Espresso:tm: Aluminum Grinder Setting Dial for Eureka.

I have now just ordered another unit for my fourth grinder from Eureka.

Hopefully you or your engineering staff can sort out this problem, particularly when the grinders are already very expensive.

The Eureka Mignon Libra is

The Eureka Mignon Libra is an absolute game changer! It is by far the quietest grinder I have ever used. In is easy to dial in, makes great fluffy, consistent grounds. Though it’s expensive it’s worth what you pay. It is a quality piece of equipment. My only complaint is the logo on the grind control knob is not centered and is quite irksome. It’s like buying a Ferrari or Lamborghini or other fine Italian sports car and having the hood badge off center by an inch or two. You notice it every time you go to drive it, or even when you just walk by. It doesn’t affect the performance, just reminds you it’s not “the perfect” grinder they claim it to be.

I Wish I could Edit My Review

I was disappointed to discover that the word Libra is nothing more than a stuck on logo. While wiping down my grinder I noticed that the L was missing. Now I have to remove the remaining letters otherwise it will really look stupid.
I expected more from a $799 grinder that I have only had a few months.

Amazing device. Make the workflow so much easier, and the grind is near perfect. Very precise movement, so be careful when making adjustments. Also, make sure to use their funnel, else you will need to tare every time.

The Mignon Libra is working

The Mignon Libra is working great, just as advertised. Been using it for about three weeks now. Dialed in very easily on day one, the knob makes it easy. Just works, place porta filter/dosing funnel on holder, hit button, get exact amount every time. It's wonderful.

First Eureka

This is my first higher end coffee grinder. I love the sleek design and ease of use. Though using dosing funnel is highly recommended. Like another review mentioned, the porta filter fork area can be easily scratched. Overall, I like using grind weight than time.
I had a small issue with ordering but Clive coffee quickly helped me to resolve!

I wish there was an option for 4-1/2 stars

This grinder is replacing a Mazzer Super Jolly grinder that I have had for over 10 years. It's gone through modifications to make it a single dose grinder but what it remains is VERY LOUD!
When I saw the Libra for the first time, the idea of a super quiet grinder that was also a grind by weight grinder was all I needed to know.
The grinder was very easy to set up and it was dialed in for my espresso machine in a matter of 2 attempts. Going from single dosing for the past 2 years to a grind by weight grinder is a giant leap of both streaming my workflow and technology (not waking my wife up with the sound of coffee grinding) In fact, the first morning I used the grinder, my wife slept through the entire process. That was never the case with the Mazzer Super Jolly.
The only 2 very minor complaints I have with the grinder are in the materials used in the construction. The hopper lid has a dimple right in the middle from injection molding. The lid being made of clear plastic, that dimple is very noticable. A black plastic lid, dimple free would look so much better and more in line with the overall high quality look of the grinder.
Second, the aluminum parts used behind the portafilter fork are very soft, and scratched easily from the dosing funnel rubbing against it. Once I saw the scratches I of course modified how I inserted the portafilter into the fork.
The grinder makes beautiful fluffy grounds and, once recalibrated, doses out consistent, accurate weights.
Bottom line, it looks great, is extremely quiet and does what it's designed to do efficiently. Now to look for a replacement lid cause this one is driving me crazy. LoL.
Thanks to Tony and Clive Coffee for the great customer service!
