Know before you buy
The Mignon Libra features an integrated scale that monitors the weight of the grounds in real-time. You simply set your desired dose in grams on the touchscreen, and the grinder automatically stops the motor once that exact weight is reached, ensuring consistent dosing without needing a separate scale.
Yes, the stepless micrometric adjustment allows you to dial in settings for everything from fine espresso to coarser drip coffee. However, because it is optimized for precision dosing, it is best suited for users who frequently switch between these methods or prefer a dedicated setup.
The grinder operates at approximately 64 decibels. While no professional-grade grinder is silent, Eureka’s quiet technology makes it significantly less disruptive than many other high-performance grinders in its class.
The ACE (Anti-Clumps & Electrostatic) System is designed to prevent static buildup and clumping during the grinding process. This ensures that the coffee grounds remain fluffy and consistent, which helps prevent channeling and promotes even extraction in your portafilter.
With a footprint of 6 inches by 6 inches and a height of 14 inches, the Mignon Libra is quite compact. It is designed to fit comfortably under most standard kitchen cabinets while maintaining a professional-grade build.
The Mignon Libra is specifically engineered for its weight-based workflow. While you can adjust the grind size manually, the system is designed to prioritize the precision of the integrated scale for every dose.
