Eureka Mignon Libra Coffee Grinder

The Libra features a built-in scale that grinds by weight rather than time. This ensures you get the exact dose you need every time, eliminating the need to manually weigh your portafilter before and after grinding.

This grinder is specifically engineered for espresso. While it offers stepless adjustment, its 55mm flat burrs and internal geometry are optimized for the fine grind size required for espresso, rather than coarser settings like French press or pour-over.

Yes, the Anti-Clump and Electrostatic (ACE) system is highly effective at neutralizing the static charge that causes grounds to fly or clump. It results in a much cleaner grinding process and more uniform distribution in your portafilter.

The Libra utilizes Eureka’s signature Silent Technology, which significantly dampens the noise produced by the motor and burrs. It is noticeably quieter than many other professional-grade grinders, making it ideal for home kitchens where you don't want to wake the house.

The Libra is designed for on-demand grinding, but it is best suited for users who stick to one or two bean types at a time. Because it uses a stepless micrometric adjustment dial, you can make precise changes, but it is not intended for frequent, drastic shifts between vastly different roast profiles.

Unlike grinders with fixed 'clicks' or steps, the stepless system allows for infinite, granular control over your grind size. This is essential for espresso, as it lets you dial in the perfect extraction time by making tiny, precise adjustments that aren't possible with stepped systems.
