EspressoBot Comparison

Machine Overview

Grinder 1, the Niche Duo, is priced at $700 and is designed for advanced users. In comparison, Grinder 2, the Rancilio Rocky SD, comes at a more budget-friendly price of $440 and targets beginner users. Both grinders fall under the semi-automatic type and are from well-known brands in the coffee industry.

Brewing Comparison

In terms of grinding information, the Niche Duo utilizes an 83 mm flat burr made of hardened steel with a stepless adjustment feature, allowing precise adjustments at a scale of 1 micron. On the other hand, the Rancilio Rocky SD features a smaller 50 mm flat burr made of steel and a stepped adjustment mechanism that allows for a coarser range of adjustments up to 10 microns. The Niche Duo has a single-dose hopper type while the Rocky SD relies on a hopper for bulk dosing. This difference allows for less retention and wastage in the Niche Duo whereas the Rocky SD may offer convenience for those grinding larger amounts at a time.

Features Comparison

Both grinders have notable features, with the Niche Duo offering swappable burrs for easy customization and maintenance, while the Rancilio Rocky SD does not support this option. The grind range of both grinders is specifically suited for espresso. Neither grinder has adjustable RPM, meaning they operate at fixed RPMs for consistent grinding speeds, with the Niche Duo revolving at 530 RPM and the Rocky SD at 1350 RPM.
