Eureka Mignon Libra Overview
The Eureka Mignon Libra is an Italian-made, weight-based home espresso grinder that builds on the Mignon series. Its Intelligent Weighing System lets you program doses by weight in tenths of a gram, with a variation of only 0.2g per grind cycle.
The body is powder coated aluminum, and the adjustable portafilter fork and cradle are designed to fit portafilters from any manufacturer through a hand-adjustable stop screw at the base. The touch screen is the same as on Eureka grinders such as the Mignon Specialita and Turbo. Eureka highlights its ease of use, grind consistency and compact size, and says the Libra delivers double shots within 10 seconds with only 0.2g of variability. For buyers who want an Italian option among weight-based grinders, it fills that role.
