The Fellow Opus is a versatile coffee grinder designed to offer a wide range of grind settings for various coffee brewing methods, from espresso to cold brew. It boasts 41 distinct grind settings, allowing users to achieve precise grinds for their preferred coffee.
Function Description:
The primary function of the Fellow Opus is to grind whole coffee beans. It is equipped with 40 mm stainless steel conical burrs, which, combined with a unique cutting geometry and grind adjustment architecture, ensure precise grinding. The grinder is designed for single-dose loading to maximize bean freshness, with a load bin lid that can be flipped over to serve as measuring compartments for 20 grams and 40 grams, or filled to the top for 100 grams. The grind size is selected using a grind adjustment ring, which rotates to choose from fine (1) to coarse (11) settings, encompassing all 41 options. The Opus also features a power button with a timed auto-stop function, allowing for grinding durations of 30, 60, or 90 seconds with short presses, or a full 2 minutes with a long press. The device automatically turns off when finished. For espresso preparation, the Opus includes a portafilter dosing cup that converts the catch to be compatible with 54 mm and 58 mm portafilters.
