Overview
The Eureka Mignon Libra combines single-dose design with an integrated scale for grind-by-weight precision. The built-in weighing system automatically stops grinding when the target dose is reached, eliminating the need for a separate scale in the workflow. The same excellent 55mm flat burrs deliver clean espresso grinding, and the scale accuracy rivals standalone precision scales. The Libra represents the ultimate convenience in the Mignon single-dose lineup, automating the one step that still required manual attention in other single-dose grinders.
The Eureka Mignon Libra features a 55mm flat burr set, crafted from steel. The burrs spin at 1350 RPM, offering fast grinding for high-volume use. Grind retention is approximately 0.5g, which is impressively low and suitable for single-dose workflows.
At $549, the Eureka Mignon Libra is aimed at serious home baristas who understand the importance of grind quality. Key workflow features include single-dose design (no hopper needed) and stepless grind adjustment for infinite precision. The flat burr design produces a more uniform particle distribution, prized for clarity and sweetness in the cup.
The Eureka Mignon Libra is weighing 6.0 kg, manufactured in Italy, powered by a 310W motor. Its footprint measures 120 x 180 x 350 mm (W×D×H).
