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.

This grinder has made my workflow so much quicker. Going from a hand grinder to this, I can pull two double espressos in around 3 minutes, compared to around 15mins beforehand.
I love the grinder , the weight is spot on every time I check with the scales . The only issue I have is that I have the Lelit Bianca 3 and the single dose filter basket moves when grinding generating an FH code , this stops grinding .
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.
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.
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?

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.
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.

Let customers speak for us
from 1690 reviewsThis little gadget is one above budget models, delivery and tax adds to it.
I can't speak to durability because not had it that long, but feels sturdy compared to many and gives a whizz!
These beans intrigued me with the 'Super Crema' adjective and so I ordered a 250 g pack to try and also offered it to a few colleagues for comment. The instant they tasted it they were over the lunar surface in a matter of seconds with positive vibes about this bean. I wasn't quite so sure as I was still making mine but what a taste - well rounded and smooth and very alive in the mouth, an absolute all rounder for many coffee making methods and well worth a try. Well priced as well.
Great coffee straight out of the grinder 👍
After months of research into single dose coffee grinders and a poor experience with a DF grinder which I sent back, I took a leap of faith and it most definately paid off.
I was originally looking at the zero 55 as was on special offer, however had read lots of reviews about the the bigger dial making small adjustments much easier and with the upgraded 65mm burrs, plus the catch cup cover to prevent mess, it just met all my needs including looking great and being within my budget.
I’ve been using this for a couple of months now and find dialling in simple along with getting consistent shots with excellent flavour.
Finding the zero point was easy enough and there are plenty of videos online to support with this.
A big bonus I've found is getting zero static or mess and no cloggging of the chute at this point. I find the bellows do an excellent job at clearing the grinds.
I would 100% recommend this grinder.
Fast delivery, virtually next day. Very well packed. Helpful staff answering my questions! Than you, Clumsy Goat!
This tamper fits the Gaggia Classic Evo 2013 basket tightly. It has noticeably increased the draw time and consequently gives s richer flavour. The resulting puck is drier. Impressive.
Beautiful flat white tumbler that just feels right.
Love these, they look so good and I’ll definitely be purchasing more.
Consistently great coffee with this blend I have been buying this for years. My preference is a dark roast & the taste is excellent.

Clumsy Goat Fairtrade Peruvian Coffee Beans - 100% Arabica
Speedy delivery securely packaged and easy to set up. A vast improvement to my home setup and delivers all the promised enhancements. My coffee brewing has now entered a professional level. I puchased as an extra the King size dial, which was easy to fit and makes it easier to use with my aging eyesight and clumsy fingers. Works well for Espresso (Sage Dual Boiler), Bialetti Stove Top and wacaco pixapresso
Ordered the new Gaggia Classic E24 Italuan coffee machine from Clumsy Goat Coffee.
It was the best price, the delivery was super quick and the follow up support and service has been excellent.
It's pretty, it has a nice weight to it, and (perhaps unsurprisingly) it works well with a Motta Competition 2-cup filter basket
Every espresso machine owner needs a tamping mat, so why not have a beautiful black cat-shaped one?
It is really cute, and super practical as well - a tamper sits comfortably on the cat's head, a groove is available for spouted portafilters (works well with the stock Gaggia Classic portafilter) and there is just enough space to the right of that to tamp a naked/bottomless portafilter.
Would be a great gift for the cat & espresso lover in your life (which can be yourself..!)
In love with my moccamaster
Fast and delicious, so easy to use and clean
Just perfect
