Know before you buy
The Eureka Mignon Libra features an integrated scale that monitors the weight of the coffee as it is ground. You simply set your desired dose in grams on the touchscreen, and the grinder automatically stops once that exact weight is reached, ensuring consistent results without needing an external scale.
While the Libra is capable of coarser grinds, it is specifically optimized for espresso. The stepless adjustment mechanism is designed for the fine-tuned precision required for espresso, and the weight-based dosing is calibrated for smaller, espresso-sized doses.
The Libra operates at approximately 64 decibels, which is notably quiet for a home espresso grinder. It is designed to minimize noise, making it a great choice for early morning use without disturbing the rest of the household.
The 55mm hardened steel flat burrs provide a uniform grind particle size, which is essential for achieving a balanced and sweet espresso extraction. Their size strikes a perfect balance between speed and heat management, ensuring your beans aren't overheated during the grinding process.
Yes, the stepless adjustment dial allows for infinite, micro-adjustments rather than fixed steps. This gives you complete control to fine-tune your grind size to the exact micron, which is necessary to get the best flavor out of different coffee roasts.
The grinder has a compact footprint measuring 5 inches wide and 7.5 inches deep. Its height is 17 inches, so you should check the clearance under your kitchen cabinets to ensure it fits comfortably.
