Eureka Mignon Libra Overview

The Eureka Mignon Libra is an Italian-made, weight-based home espresso grinder that builds on the foundations of the Mignon series with precise weight-based grinding and dosing. Thanks to the Intelligent Weighing System, the Libra’s doses are programmed by weight within 1/10th of a gram and are accurate with a variation of just 0.2g per grind cycle. Housed in powder coated aluminum and featuring an adjustable portafilter fork, this is the weight-based grinder your prosumer has been waiting for.

Features and Performance

The Libra’s display is the same vibrant touch screen featured on grinders like the Mignon Specialita and Turbo. Grinding weight is adjustable in tenths of a gram using the "+" and "-" buttons, and you can freely switch between single and double shots. Eureka’s new Intelligent Weighing System uses a unique anti-vibration design that allows the Libra to continue grinding even when bumped or knocked. To eliminate waste, the motor will also stop immediately if the portafilter is removed to prevent grinds from dispensing all over the counter. If you’re still experimenting with your dose, the freehand dispensing can still be achieved via manual mode.

For performance, it's equipped with 55 mm flat hardened steel burrs and a strong 1350 RPM motor with an output of 1.4 - 1.8g/s for espresso. Eureka's ACE system helps prevent clumping by eliminating static in ground coffee, which in turn ensures dose consistency.

It's quiet, measuring in at about 73 dBA, so you won't ever need to stop a conversation to make your drinks. The Libra is equipped with Eureka's patented micrometric adjustment for smooth stepless dialing in, made even easier by the inclusion of the extra comfort knob. The Libra’s unique portafilter fork and cradle are still adjustable to fit designs from any manufacturer with a hand adjustable stop screw located at the base of the grinder.

Why You Should Get It

The Eureka Mignon Libra is an excellent competitor in the arena of weight-based grinders. It inherits the best the Mignon series has to offer in terms of ease of use, grind consistency and compactness, while delivering double shots within 10 seconds and with only 0.2g of variability. Plus, for those looking for an Italian alternative the Libra is it.
