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.

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.

Buick Coworkers go mad for Clumsy Goat

I run a cowork space and the coffee is one of the main reasons people come! WE all LOVE it. Occasionally I run out and have to swap beans ... complaints flood in. Other beans I've used clog my machine up, the super crema works brilliantly. Great customer service too. Thank you Clumsy Goat.

Good grinder

My first real coffee grinder, it's sleek and quick. Not too noisy as well. The small footprint is really nice I can easily store it in a cupboard when I need countertop space.

Great product, Good Prices, FANTASTIC service

Excellent quality grinder, quiet, awesome grinding consistency producing 18g in 9.2 seconds. This is. Huge step up. The fork is not so good for Sage 54mm integrated portafilters, so removed the fork, you can get mods for this on Etsy. The price was competitive and the staff were amazingly flexible when I needed to change the colour before they shipped it. Really nice humans at the of a phone!
