Exact-model grinder profile

Fellow Opus

A versatile and compact all-purpose route, but the two-ring adjustment is less immediately readable than one external dial.

Burrs40mm six-blade conical

Adjustment41 visible settings plus inner micro-adjustment

Best fitDesign-led mixed brewing in a low cabinet space

Multi-factor Index ratings

Six evidence bands that reveal the intended job.

Espresso and filter are assessed separately so an excellent specialist is not punished for refusing the wrong job. Bands use published adjustment, dosing, size, price and evidence—not a claimed taste test.

Updated 2026-08-03 · editorial fit ratings, not owner stars or laboratory measurements

Espresso fitStrong

Brew-range claim and adjustment resolution; not a measured taste score.

Filter fitStrong

Published brew range, burr format and whether filter is the primary design job.

Dosing workflowStrong

Single-dose, timed, auto-stop and direct-to-portafilter convenience.

Counter fitVery strong

Calculated from the published 12.9cm × 21cm footprint.

Value contextMixed

Capped because a stable UK price was not verified.

Evidence confidenceMixed

Confidence in exact model, UK price, plug, dimensions and manufacturer documentation.

How to read this: these are deliberately broad specification-led bands, not laboratory scores. A machine can be strong for control and limited for speed—or very strong for filter and intentionally limited for espresso.

Index verdict

What the published evidence suggests.

The manufacturer page supports grind range and dimensions; UK price, plug and support depend on the chosen retailer.

Reasons to shortlist

Espresso-to-cold-brew range
Low height
Anti-static chute
Timed auto-stop

Reasons to pause

Inner micro-ring adds a second adjustment layer
UK voltage and warranty must be confirmed
