EspressoBot Comparison

Machine Overview

The Mahlkonig X54 is priced at $649 and is designed for intermediate users, while the Fellow Opus is significantly more affordable at $195 and targets beginners. Both brands offer semi-automatic grinders, but they cater to different segments of the market based on the skill level required for optimum use. The higher price of the X54 reflects its advanced capabilities suitable for more experienced baristas. In contrast, the Fellow Opus provides a more budget-friendly option for those just starting out in espresso preparation.

Brewing Comparison

In terms of grinding information, the Mahlkonig X54 is equipped with flat stainless steel burrs with a diameter of 54mm and features a stepless adjustment mechanism for precise grinding, activating via a portafilter button. The grinder allows for a grind range suitable for all brew methods, including espresso, with an adjustment scale of 1 micron. The Fellow Opus utilizes conical stainless steel burrs (40mm) and employs a stepped adjustment system with an adjustment scale of 5 microns, which can also accommodate a range of brewing methods. It uses a single-dose hopper and features timed auto-stop dosing along with a manual on/off option, making it intuitive for beginners.

Features Comparison

When comparing key features, the Mahlkonig X54 does not support adjustable RPM, while the Fellow Opus also lacks this feature. Both grinders boast a full grind range from pour-over to espresso, catering to a variety of brewing needs. However, the Fellow Opus allows for swappable burrs, giving users the flexibility to customize or upgrade their grinding experience, a feature not available with the Mahlkonig X54. In contrast, the X54 is designed for more precision with its stepless adjustment but lacks the convenience of interchangeable burr options.
