Machine Overview

The Fellow Opus, priced at $195, is a semi-automatic grinder designed for beginners, making it a great entry point for coffee enthusiasts. In contrast, the Kingrinder K2 offers a more budget-friendly option at $79, also targeting beginners but with a manual design that requires more hands-on interaction for grinding. Both brands aim to provide quality options for users who are exploring espresso preparation.

Brewing Comparison

In terms of grinding information, the Fellow Opus features a conical burr design with a burr diameter of 40mm, using stainless steel and offering a stepped adjustment mechanism. It employs a single dose hopper with timed auto-stop dosing, while the Kingrinder K2 also features a conical burr but with a larger burr diameter of 48mm and utilizes a manual hand-crank for operation. The K2 also has a threaded catch cup for dosing, which allows for a straightforward manual process. Both grinders can cover a grind range suitable for various methods, including espresso.

Features Comparison

Regarding features, the Fellow Opus does not have adjustable RPM but supports a comprehensive grind range from pour-over to espresso and includes swappable burrs for variety. The Kingrinder K2 lacks both adjustable RPM and swappable burrs but maintains a similar grind range capability. The Opus offers lower retention, enhancing its efficiency, while the K2's manual operation can allow users to have more control over grind consistency through hand crank adjustment.
