Eureka Mignon Libra 65 All Purpose – Grind-by-Weight Grinder for Espresso and Filter
Espresso into the portafilter in the morning, filter into the cup in the afternoon, both by weight: the Eureka Mignon Libra 65 All Purpose grinds with 65 mm flat burrs and an integrated scale.
Eureka describes it as one grinder for all brew methods. The burrs are designed for espresso and filter, and the upper burr is closed (Blind Upper Burr). A precision scale in the fork stops grinding at the target weight, and the large adjustment dial with revolution counter makes switching between espresso and filter easy to keep track of.
Features of the Mignon Libra 65 All Purpose
Instant Grind Weighing Technology
Grinding by weight in just a few steps. Eureka's patented system grinds by weight instead of by time. That simplifies your routine, saves time and avoids wasted coffee.
65 mm All Purpose burrs with Blind Upper Burr
According to Eureka, the special burr geometry suits espresso and all filter methods and is meant to bring out clarity and liveliness in the aromas. The closed upper burr is the key to very low retention.
Very precise
According to Eureka, the dose deviates by no more than ±0.2 g. That minimises coffee waste and keeps your recipe consistent.
No coffee wasted
An anti-vibration system lets grinding finish cleanly even if the portafilter gets bumped. If you take the portafilter out, the grinder stops immediately.
Easy to use
On the touch display you set the amount for single and double doses, grind by weight in continuous mode too, switch between single and double while grinding without losing coffee, and use start and pause.
Our opinion is one of many: burr sets are like engines, subjective, there is no best one. 65 mm flat burrs give a clear cup in filter, and in espresso, chocolatey and nutty beans produce dense, round cups. Extract by weight; 1:2 is a good starting point.
The details in daily use
King Size Dial with revolution counter
The patented adjustment dial sits on top of the grinder. It makes grind adjustment easier, allows very fine changes and simplifies switching between brew methods. The adjustment itself is stepless (Stepless Micrometric Regulation, patented by Eureka).
Mignon Dosing Funnel included
The included dosing funnel reduces spilled coffee. Eureka recommends it for single doses above 8 g, double doses above 15 g and triple doses of 20–22 g.
Special fork
Sturdy and easy to adjust. The fork holds steady and takes both the portafilter for espresso and the All Purpose Cup for filter coffee.
Quiet
Eureka's exclusive Silent Technology noticeably reduces grinding noise, partly through an anti-vibration system. The ACE system counters clumping and static.

Who the Libra 65 All Purpose is made for
The Libra 65 All Purpose is for everyone who wants to grind espresso and filter by weight with the same grinder. Eureka recommends it for light roasts. If you drink almost only espresso with darker roasts, you'll find the Libra 55 among our Eureka coffee grinders, designed for espresso and darker roasts. Nobody needs both; if you want it, you know why.
The Libra 65 is a grinder with a bean hopper, not a single-dose grinder. For single dosing: the Lagom series from Option-O. For everyone who wants a hand grinder that is affordable and precise: Comandante and Timemore. Our comparison of grind-by-weight grinders gives you an overview.
Our advisory tool helps you pair grinder and machine. You can arrange a free consultation in the showroom, by phone or virtually. If you want to test grinders and machines side by side, book the comparison workshop in Zurich, an option, not a requirement.
What goes with it
Scales: the grinder doses on its own, but you still need a scale for the espresso output weight or the pour for filter. For everyone who wants scales that are affordable and precise: the Normcore Collection. If you want an app, flow-rate display and Bluetooth: the Acaia Collection.
Filter: for everyone who wants brewers that are affordable and precise, Hario V60 and AeroPress. If you want more: the BIRD from Weber Workshops. Kettles: AURA Standard or, with temperature control, AURA FLUX from Varia.
Puck prep: for everyone who wants a tamper, WDT tool and puck screen that are affordable and precise, the tools from Normcore. If materials matter more to you: tamper, Moonraker and puck screen from Weber Workshops. You'll find machines in our coffee machines range.
Frequently asked questions about the Eureka Mignon Libra 65 All Purpose
What sets the Libra 65 All Purpose apart from the Libra 55?
The Libra 65 All Purpose has 65 mm burrs with All Purpose geometry and a closed upper burr, the King Size Dial with revolution counter and a fork for portafilter and All Purpose Cup. Eureka recommends it for light roasts and for espresso and filter. The Libra 55 is designed for espresso and darker roasts.
Is the Libra 65 All Purpose a single-dose grinder?
No. It has a 350 g bean hopper and grinds the dose by weight. The closed upper burr lowers retention.
Does the Libra 65 All Purpose also grind for filter and French press?
Yes. According to Eureka, the burrs are designed for espresso and all filter methods. For filter, the fork takes the All Purpose Cup, and the King Size Dial makes switching between methods easier.
Which colours are available in Switzerland?

Can I see the Libra 65 All Purpose before buying?
Our showrooms in Bern (Gerberngasse 44) and Zurich Oerlikon (Hagenholzstrasse 50b) show a wide selection, but not every model is on display at all times. Write to us at [email protected] before your visit, and we will check whether the Libra 65 All Purpose is there.
How quickly is the Libra 65 All Purpose delivered?
Throughout Switzerland and to Liechtenstein in 2–4 working days. Click & Collect in Bern and Zurich. Financing available. We answer questions during business hours or via coffeecoachingclub.ch.
Roastery tip: For espresso from the Libra 65 All Purpose we recommend Cozy Chocolate and Nutty Delight, both full-bodied with chocolate and nut. If you want maximum body without acidity, go for Very Nutty. Because the grinder also grinds for filter, Wild Peach is worth it as a fruity discovery in the V60. Other beans work just as well. That is our recommendation, one of many.
