Do a little less work and drink a little more espresso with the Open Box Eureka Mignon Libra Espresso Grinder. Eureka’s first grinder designed to dose by weight, the Libra offers some of the best workflow around thanks to its accurate dosing, 55mm burrset, and one-touch operation. A load sensor in the adjustable portafilter holder lets you program the Libra to your desired amount of grams, and operates at a touch of the screen. Inside you’ll find a bevy of further labor-saving features like a dosing funnel for a cleaner countertop, a stepless bottom burr grind adjust, and motor and outlet insulation for quieter, low vibration grinding.
