EspressoBot Comparison

Machine Overview

Grinder 1, the Eureka Mignon Specialita, is priced at $649 and targets intermediate users, while Grinder 2, the Rancilio Rocky, is more affordable at $440 and is designed for beginners. Both grinders fall under the semi-automatic category, but they cater to different skill levels depending on their respective features.

Brewing Comparison

In terms of grinding information, the Eureka Mignon Specialita uses 55 mm hardened steel flat burrs with a stepless adjustment allowing for very fine tuning (1 micron scale), making it ideal for espresso. In contrast, the Rancilio Rocky features 50 mm thermosteel treated flat burrs; it has a stepped adjustment of 10+ microns, making it simpler to operate but less precise. Both grinders come with a hopper type dosing method—timed for the Eureka and lever dispenser for the Rancilio—where the Eureka offers more consistency and accuracy.

Features Comparison

Key features reveal further differences: the Eureka Mignon Specialita has a grind range limited to espresso, stepless adjustment, and does not support swappable burrs, which may appeal to users looking for precision. The Rancilio Rocky, while also limited to espresso grind range, features stepped adjustment for ease of use and does not include adjustable RPM or swappable burrs, making it a more straightforward option for beginners but lacking the fine control of the Eureka.
