Machine Overview

The Rancilio Rocky SD is priced at $440 and is tailored for beginners, offering a user-friendly experience for those new to espresso grinding. In contrast, the Eureka Mignon Zero, available for $499, caters to intermediate users, providing them with enhanced functionality and control. Both models fall into the Semi-Automatic type category, emphasizing ease of use.

Brewing Comparison

In terms of grinding information, the Rancilio Rocky SD uses a Flat Burr with a 50mm steel burr diameter and has a stepped adjustment, suitable for espresso grinding. It features a hopper type for manual dosing with a retention of 1 - 1.5g. The Eureka Mignon Zero, on the other hand, also utilizes a Flat Burr but with a larger 55mm hardened steel diameter, offering a stepless adjustment for more precise grind settings from pour over to espresso. This grinder incorporates a single dose hopper and has minimal retention of less than 0.5g, optimizing the freshness of the grounds.

Features Comparison

Both grinders have unique key features in their grinding capabilities. The Rancilio Rocky SD operates at a fixed RPM of 1350 with no adjustable settings and is limited to an espresso grind range. Conversely, the Eureka Mignon Zero runs at 1650 RPM, providing it with adjustable RPM features, and boasts a versatile grind range from pour over to espresso. Neither grinder supports swappable burrs, indicating a permanent burr design aimed at long-term performance.
