Level with the Sage Smart Grinder Pro BCG820

The Sage Smart Grinder Pro BCG820 and the Fellow Opus Conical Burr Grinder score the same, so either is a safe pick. The Sage Smart Grinder Pro BCG820 goes first because it leaves owners a little happier. The Fellow Opus Conical Burr Grinder is the newer design.

About the Fellow Opus Conical Burr

The Opus is an electric grinder with 40mm stainless steel conical burrs. It has 41 main grind settings, set by a stepped dial. Under the hopper there is an inner ring for finer adjustment between steps, but you have to take the hopper off to reach it. It is meant to cover espresso, pour-over, drip, cafetière and cold brew.

The bean hopper holds 100g, and the lid doubles as a dosing cup. It works for single doses or for filling up for a few days. Dosing is manual: there is no timer, so you stop the grinder yourself. Fellow uses an anti-static design at the outlet to keep grounds from clinging and scattering, although it does not remove static completely.

The motor turns the burrs at 350rpm. A UK retailer's listing gives the box contents as a load bin lid, a catch cup with lid, a catch cup insert for portafilter dosing and the manuals.

What owners report about the Fellow Opus Conical Burr

We found little owner feedback for this exact model on UK pages, so this section is short. The reviews and listings we read agree on a few points.

The anti-static outlet gets credit for keeping the catch cup fairly clean. Static still builds up in the hopper on dry or humid days, particularly with light roasts, and a light mist of water on the beans or a wipe of the chute helps. Noise is described as moderate: louder than a hand grinder, but not harsh.

The stepped dial is the most common complaint for espresso. Steps can land between the ideal settings, so some people end up changing dose or tamp instead of the grind. Ultra-light roasts push the finest settings to their limit and shots can run fast. The build is mostly plastic. Reports of long-term reliability are thin, with a few mentions of motor trouble under heavy daily use.

Who the Fellow Opus Conical Burr suits

The Opus suits someone who mostly makes filter, cafetière or cold brew and wants a neat grinder with simple one-button use. It also copes with milk-based espresso drinks if you accept the stepped adjustment.

Look elsewhere if you want precise espresso dialling, a timer for dosing, or a hopper that holds a large batch. For espresso the Eureka Mignon Specialita or the Sage Smart Grinder Pro BCG820 are the better fit. For a filter and cafetière grinder with a built-in timer, the Wilfa Svart Aroma CGWS-130B is worth a look.

Questions about the Fellow Opus Conical Burr

Is the Fellow Opus quiet?

Fairly. One reviewer measured it at around 80 dB and found that acceptable. Another site calls it moderate noise, louder than a hand grinder but not harsh.

What is a conical burr coffee grinder?

It crushes beans between a cone-shaped inner burr and a ring-shaped outer burr. The Fellow Opus has 40mm stainless steel conical burrs.

Can you use a burr grinder for espresso?

Yes, if it grinds fine enough and lets you adjust in small steps. The Fellow Opus can make espresso, but its 41 settings are stepped, so fine tuning is limited. It is better suited to milk drinks than to precise straight shots.

Does the Fellow Opus produce a lot of static?

Less than most grinders, but not none. The anti-static outlet keeps most grounds in the cup, though static can still build up in the hopper, especially on humid days with light roasts.

How we score it

Every score here comes from our ranking model; no editor sets the order. We haven't read the review sites for this guide yet, so for now it is led by owners. It ranks products by how happy owners are, holding back any product few owners have rated until more agree. How many rated it and how new it is only settle close calls, and value for money earns its own badge rather than a higher place. We compared 17 models for this guide before settling on these ten.

Brands can't pay to be included or to move up. We last checked these picks in November 2026.
