Know before you buy
The Mignon Libra features an integrated scale that measures the weight of the coffee grounds in real-time as you grind. Once your pre-programmed target weight is reached, the grinder automatically stops, ensuring consistent dosing to the tenth of a gram.
While the Mignon Libra is optimized for espresso, it is capable of grinding for pour-over and French press. However, keep in mind that the adjustment dial is designed for the fine-tuning required for espresso, so switching between brew methods frequently may require some patience.
The ACE (Anti-Clumps and Electrostatic) system significantly reduces static electricity and prevents grounds from clumping together. This results in a much fluffier, more uniform bed of coffee, which helps prevent channeling during your espresso extraction.
Equipped with Eureka’s Silent Technology, the grinder operates at approximately 64 dB. It is noticeably quieter than many traditional espresso grinders, making it a great choice for kitchens where you want to avoid waking up the rest of the house.
Yes, the 300g hopper is removable, which makes it easy to clean or swap out beans. It also features a sliding gate that allows you to close off the hopper so you can remove it without spilling the beans remaining inside.
The 55mm hardened steel flat burrs provide a consistent particle size distribution, which is essential for balanced espresso shots. They offer a great balance between grinding speed and heat management, making them ideal for home use.
