Machine Overview

The Kingrinder K4, manufactured by Kingrinder, is priced at $119 and is classified as a manual grinder suitable for beginners. In comparison, the Fellow Opus offers a higher price point of $195 and is categorized as a semi-automatic grinder, also targeted at beginners. Both grinders are designed to be user-friendly, making them accessible options for those new to espresso preparation.

Brewing Comparison

When examining the grinding information, both grinders utilize a conical burr for grinding; however, they differ in the materials, with Kingrinder employing titanium-coated burrs and Fellow using stainless steel C6-40 Burly burrs. Both grinders feature a stepped adjustment system, but the Kingrinder K4 has a grind range limited to espresso, while the Fellow Opus accommodates a broader range from pour-over to espresso. In terms of dosing, both grinders utilize a single dose hopper, but the Kingrinder K4 employs a manual dosing method, whereas the Fellow Opus supports a timed auto stop for easier dosing automation.

Features Comparison

The Kingrinder K4 has a grind range solely focused on espresso and does not feature adjustable RPM or swappable burrs. However, the Fellow Opus provides a wider grind range that can cater to various brewing methods, along with swappable burrs for enhanced grinding versatility. While both grinders have retention rates of less than 0.2 grams, only the Fellow Opus boasts an adjustable RPM of 350, offering flexibility in grind speed, which can be advantageous for precision in different brew methods.
