Eureka Mignon Libra Espresso Grinder

Stop wasting beans and guessing your dose. The Eureka Mignon Libra transforms your morning ritual by bringing professional-grade, weight-based dosing directly to your home espresso setup. Engineered in Florence, Italy, this powerhouse eliminates the need for a separate scale, delivering the exact grammage you program directly into your portafilter with flawless consistency and zero mess.

The Eureka Mignon Libra featuring advanced integrated weighing technology.

Precision Grind-by-Weight Technology

The standout feature of the Mignon Libra is its integrated load cell. By grinding based on weight rather than time, you ensure that every shot is identical, regardless of bean density or hopper levels. With the ability to save two custom doses, switching between your favorite single-origin and a standard blend has never been faster or more accurate.

Stepless Adjustability and 55mm Burrs

Consistency is king, and the Libra delivers with Eureka’s signature 55mm hardened steel burrs. These burrs are specifically calibrated for espresso, providing the perfect balance of speed and particle uniformity. Combined with Eureka’s famous stepless adjustment knob, you have near-infinite control over your grind size, allowing you to dial in the perfect extraction every single time.

Silent Technology for the Home Barista

Don’t let the power fool you. Thanks to Eureka’s proprietary “Silent Technology,” the Libra operates at a remarkably low noise level of approximately 64 dB. This anti-vibration solution ensures a premium, quiet grinding experience, making it the perfect companion for early mornings when you need your caffeine without waking the rest of the house.

Designed for Workflow Efficiency

Every aspect of the Libra is built for the workflow-conscious barista. The “Bottom Burr Adjust” design means that you can clean your grinder without losing your specific grind setting, saving you time and coffee. Furthermore, the included dosing funnel helps maintain a pristine station by capturing every ground, ensuring that what you weigh is exactly what ends up in your basket.
