EspressoBot Comparison

Machine Overview

The Rancilio Rocky SD is a beginner-friendly espresso grinder priced at $440, which positions it as an accessible choice for those new to espresso preparation. In contrast, the Weber Key is designed for advanced users and has a significantly higher MSRP of $1999, making it a premium option for aficionados. Both grinders fall into the semi-automatic category, catering to different levels of expertise.

Brewing Comparison

In terms of grinding information, the Rancilio Rocky SD utilizes a flat steel burr with a diameter of 50 mm and features a stepped adjustment system, allowing users to achieve espresso-specific grind settings. It operates using a manual switch and has a hopper type designed for regular dosing. Meanwhile, the Weber Key employs an 83 mm TiN-coated conical burr, which provides a potentially enhanced grinding performance, and its single dose hopper is advantageous for freshness. The Weber also features a stepped adjustment mechanism with precision adjustment at 5 microns, catering to users who value fine-tuning.

Features Comparison

When comparing key features, the Rancilio Rocky SD does not have adjustable RPM, while the Weber Key offers this flexibility with a range from 30 to 300 RPM, allowing for customization based on user's preference. The grind range of the Rocky is limited to espresso, whereas the Key supports a broader range from pour-over to Turkish, facilitating versatility in coffee preparation. Additionally, the Weber Key allows for swappable burrs, providing users the opportunity to change burr styles if desired, a feature absent in the Rocky SD.
