Eureka Mignon Libra

Equipment notes

The Mignon Libra is a grind-by-weight espresso grinder from Eureka, the Italian grinder maker. Handcrafted in Florence, it adds a built-in scale to Eureka's Mignon line, pairing a 55mm flat steel burr with weight-based dosing. The 55mm flat steel burr gathers particles evenly to provide the uniformity espresso needs, and stepless micrometric adjustment allows fine dialing. Its core is controlling the dose by measured weight rather than time, grinding directly into the portafilter to a target in grams for higher repeatability. The static- and clump-reducing ACE structure and a vibration-resistant design support dosing consistency. It fits the home barista who wants to repeat espresso extractions with gram-level precision, and anyone seeking to reduce cup-to-cup variance with a compact weight-based grinder.
