The do-it-all grinder for brew-it-all homes. Opus is built for coffee drinkers who want one grinder that handles everything — from true espresso to coarse cold brew — without compromise.
At its core are Fellow’s C6-40 Burly Burrs™: 40 mm, 6-blade conical burrs powered by a high-torque motor delivering 6 Nm of force at 350 RPM. The result is consistent, balanced extraction across 41+ precision grind settings, with expanded micro-adjustment via the inner ring for dialing in espresso.
Compact on the bench. Serious under the hood.

Designed for Real Homes
Opus was engineered to replace blade grinders and entry-level burr grinders with a true all-purpose solution. Whether you brew espresso, pour-over, AeroPress®, French press, drip machine, or cold brew, Opus delivers clarity, sweetness, and body with minimal fuss.
Thoughtful design touches — like the grind guide under the lid and mess-reducing spout — make daily use intuitive and clean.
