About the Product

One of the newest additions to Eureka's range of Mignon grinders - the LIBRA boasts inbuilt weighing technology for extreme precision, reducing waste and improving coffee flavour. Perfect for home users and small commercial outlets.

We received a pre-release version here at Clumsy Goat Coffee for us to test prior to its launch in the UK and we've been really impressed. The Grind By Weight system is a feature normally found on much more expensive grinders, such as the Mahlkonig E65 GBW, which retail around £2,000.

You can expect a grinder that's very easy to dial in, with impressive grind consistency, quiet operation, less coffee waste and strong reliability.

Key Features:

Extreme Precision - With a dose consistency of 0.1 - 0.15g, you can achieve optimum in-cup results and minimise coffee waste.

Intuitive Touch Display - Easily set the quantity for single and double shot; grind by weight, even in continuous mode; switch from single to double (and visaverse) during the grinding process without any coffee waste.

Inbuilt Scale - Be able to weigh the ground coffee into the filterholder while grinding.

Hands-Free Operation - Adjustable in height and compatible with any type of filter holder (including naked).

Stepless Micrometric Regulation System - This ensures incomparable precision and grinding performance with infinite adjustment points.

Ace System - Anti-Clumps & Electrostaticity system prevents clumps from developing and eliminates the electrostatic charge of ground coffee, ensuring incomparable cleanliness and dose consistency.

Silent Technology - A marked reduction in the grinding noise compared to comparable grinders.

Libra grinder has Faulty scale

Heard a lot of good reviews about this grinder. So ordered one for myself.
But I have to admit the Libra grinder delivered to me has a faulty scale. Does not dispense a correct quantity even after several attempts to recalibrate as per Eureka suggestions.
Currently checking with Clumsy Goat team to sort this out.
So far haven't heard back what happens next.

Good but arrived without the dosing funnel

Very happy with the machine, grinds fast and quiet but no dosing funnel was in the box which I was expecting to be in the box.

Grinding coffee couldn’t be easier

The Eureka Mignon Libra takes all the fuss out of grinding coffee, this is as convenient as you get, it makes you feel like you’re preparing coffee in a coffee shop. It took 3 or 4 cups to find my setting and now the grinding process has been reduced to 10 seconds. Consistent weights and grind size means you set it and forget about it. I love it. Does it help that it looks fantastic?

Great little Grinder for the Price

I wanted a grind by weight grinder that didn’t break the bank. Absolutely love it! Coffees are more consistent and better tasting, partners with my niche giving me the ultimate setup. Clumsy Goat delivery was great and responsive.

A brilliant grinder

I ordered the Libra as Grind by weight was exactly what I was looking for. The quality of the grind from the flat burrs is excellent and the weight is often within 1/10th gram.
I was a little disappointed that the ‘LIBRA’ logo was faulty as the letter I was missing. After a little to-ing and fro-ing with the retailer we settled the problem with a transfer for me to replace the logo myself and a few extras by means of an apology. Had there not been this small issue I would have gladly rated the Libra with 10/10
(BTW the offer was there for the grinder to be returned for repair but I chose not to as I needed the machine).

Mignon Libra

Dial In with Accuracy, Grind by Weight

The Eureka Mignon Libra delivers the precision of commercial grinders like the Mahlkönig E65 GBW—at a fraction of the size and price. With real-time grind-by-weight functionality, it’s engineered to give baristas at home or in small cafés complete control over every dose.

Unlike timer-based grinders that require frequent recalibration, the Libra weighs each dose as it grinds, ensuring incredible consistency and less coffee waste. You’ll never need to weigh your portafilter before and after again—it’s all built into the machine.

With its smooth touchscreen interface, stepless grind control, and whisper-quiet motor, the Libra combines high-tech performance with everyday usability. It’s everything you need for repeatable, flavour-focused results.

Mignon Libra

Grind Quality, Simplified

With the Mignon Libra, Eureka has blended high-end grind performance with simplicity and convenience. At its heart is a 55mm flat burr set, delivering exceptional uniformity for espresso, and the ability to adjust grind size with near-infinite precision.

The touchscreen makes it easy to toggle between single and double shots, while the grind-by-weight system ensures you’re never left with a soggy, over-packed puck or an underfilled basket. You get the exact dose you need—every time.

It’s a grinder designed not just to perform, but to perform simply. No noisy motors, no complex calibration—just reliable, repeatable results in a sleek package.

Clumsy Goat Fairtrade Italian Espresso Coffee Beans – 100% Arabica

08/11/2025

I bought a replacement espresso machine as my old ones pump failed. The ordering process was easy, the price right and delivery arrived to my scottish island home quickly and with no surcharge. What impressed me most was the packaging. The Rancilio machine I bought was well packed from the factory, but it was encased in a larger box with extra protection, which is superb as I've had deliveries from other companies that have not survived the trip.
