EspressoBot Comparison

Machine Overview

Both the Eureka Mignon Libra and Mignon Oro are semi-automatic espresso grinders available at the same MSRP of $799. The Mignon Libra is geared towards intermediate users, while the Mignon Oro is designed for advanced users, indicating a difference in the target skill level and the features provided in each model.

Brewing Comparison

In terms of grinding information, both grinders use a flat burr method, but the diameter of the burrs differs, with the Mignon Libra featuring 55mm stainless steel burrs and the Mignon Oro boasting larger 65mm steel Pure Diamond® burrs. Both grinders have a stepless adjustment system which allows for precise grind settings, but they differ in their hopper types and dosing methods. The Mignon Libra employs a traditional hopper and offers both grind by weight and timed dosing, while the Mignon Oro utilizes a single dose hopper with an on/off button for activation, reducing retention to less than 0.1 grams, which can enhance the freshness of the grounds.

Features Comparison

Key features also distinguish the two models; the Mignon Libra has a grind range specifically for espresso and does not feature adjustable RPM settings or swappable burrs. On the other hand, the Mignon Oro allows for a similarly focused grind range while also providing a motor RPM of 1650, making it potentially faster but lacking in the adjustable RPM feature as well. Neither grinder supports swappable burrs, indicating a commitment to their respective burr designs for optimal performance.
