Eureka Mignon Libra 55 Digital Grinder – White

Overview

The Eureka Mignon Libra 55 Digital Grinder in White blends precision espresso grinding with a bright, contemporary aesthetic that complements modern kitchens and minimalist coffee bars. Combining Eureka's patented grind-by-weight technology with a compact footprint, the Libra delivers remarkably consistent espresso dosing while simplifying the entire grinding process.

Instead of relying on timed grinding, the integrated Instant Grind Weighing (IGW) system continuously measures coffee as it is dispensed into the portafilter, automatically stopping once the programmed weight has been reached. The result is greater shot-to-shot consistency, less coffee waste, and a smoother daily espresso routine.

Equipped with 55mm hardened steel flat burrs, Eureka's patented stepless micrometric adjustment system, Silent Technology, and an intuitive touch display, the Libra gives home baristas the level of control normally associated with commercial equipment while remaining exceptionally easy to use.

Finished in crisp matte white, this version offers a clean, modern look that pairs beautifully with white, stainless steel, and wood-accented espresso machines, making it an ideal centerpiece for thoughtfully designed coffee stations.

• Users building bright, modern coffee stations.
• Espresso enthusiasts seeking greater consistency.

The defining feature of the Mignon Libra is Eureka's patented Instant Grind Weighing Technology. Rather than estimating doses by time, the grinder measures coffee continuously throughout the grinding process and automatically stops once the desired weight has been reached.

An integrated anti-vibration weighing system further improves measurement stability, while automatic grinding interruption when the portafilter is removed helps eliminate unnecessary waste.
