Fellow Opus conical burr grinder overview
This Fellow Opus espresso review looks at a home grinder for people who want one machine for multiple brew methods, without buying a separate grinder for every cup.
Fellow Opus conical burr grinder review
Fellow describes Opus as a powerful all-purpose grinder that grinds coffee from espresso to cold brew.
For shoppers, that range is the main reason to look at it, especially if they want one grinder to do more than one job at home.
Designed in San Francisco for home brewing
Fellow says it is designed in San Francisco for home brewing.
Design and build
The design keeps the footprint modest and uses plastic materials with stainless steel conical burrs.
Compact size and materials
Its dimensions are 210mm x 129mm x 268mm, and it weighs 4 lb / 1.81 kg. Grind capacity is 110 grams, burr size is 40 mm, and materials are High Quality ABS/PC/PP Plastics and C6-40 Burly Burrs™: Stainless Steel Conical Burrs.
Those are the listed size and build details, which are the main numbers to compare if you are deciding whether it fits your counter.
Single-dose loading and auto shutoff
The grinder uses a single dose load bin with a measuring scale around the rim. The catch snaps beneath the chute to keep grounds falling neatly, and the front power button sits on the base while the grinder shuts itself off automatically.
Features and performance
The feature set is broad, and the published performance notes are practical rather than flashy.
41 settings from espresso to cold brew
Opus has 41 settings from fine (1) to coarse (11). CoffeeGeek measured around 74db under load and said the grinder never seems to stumble or hesitate.
Reviewed said it produced excellent results across grind sizes and each batch was impressively consistent, though slightly less consistent than the Ode.
Dosing lid, anti-static tech and timed autostop
The volumetric dosing lid can measure 20 grams, 40 grams, or 100 grams of beans. Opus also includes anti-static technology, no-tool calibration, and timed autostop.
Portafilter and brew-method compatibility
The portafilter dosing cup converts the catch to be compatible with 54 mm and 58 mm portafilters. Fellow lists the brew range as espresso, AeroPress®, pour-over, electric coffee makers, French press, cold brew, and cupping.
Cleaning and maintenance
The maintenance notes are straightforward: brush, wipe, and clear out residue when needed.
How to clean the chute, burrs and exterior
Fellow’s cleaning article says the load bin and outer burr can be removed for brushing, and the exterior can be wiped with a non-abrasive damp cloth. If you do not use it regularly, clear the chute of old coffee residue.
Daily bean handling and storage tips
Fellow says not to store beans in Opus and to pour beans in right before grinding.
