Know before you buy
The Eureka Mignon Libra features an integrated scale in the portafilter fork. You set your desired weight on the touchscreen, and the grinder automatically stops the motor once that exact dose is reached, ensuring consistent output without needing an external scale.
The Libra is specifically optimized for espresso. While the stepless adjustment allows for a wide range of settings, the burr geometry and the grind-by-weight system are designed to provide the precision required for fine espresso grinds rather than coarser filter methods.
The stepless micrometric system is highly intuitive and allows for infinite, granular adjustments. Because there are no preset 'clicks,' you can make tiny, precise changes to your grind size to perfectly dial in your espresso extraction.
The Libra operates at approximately 64 decibels. Thanks to its anti-vibration technology and solid aluminum construction, it is significantly quieter than many other professional-grade home grinders.
Yes, the portafilter fork is adjustable to fit various portafilter handle shapes and sizes. It is designed for hands-free operation, allowing you to grind directly into your basket without holding it in place.
Cleaning the burrs is straightforward. Because the adjustment mechanism is located on the bottom burr, you can remove the top burr for cleaning without losing your current grind setting, making it easy to keep the grinder performing at its best.
