Equipped with a powerful motor and 40 mm conical burrs, Opus brings out the sweetness, body, and clarity that define a truly great cup. Designed for ease and elegance, this sleek, all-purpose grinder is perfect whether you're upgrading from a blade grinder, refreshing your countertop, or embracing freshly ground coffee at home.
It’s All the Range
Opus is the rare all-purpose grinder that covers every brewing style—from true espresso to cold brew. With 41+ adjustable settings and an inner ring for even finer control, it delivers precise grind sizes for pour-over, French press, AeroPress®, and more.
Consistency You Can Taste
With its C6-40 Burly Burrs™—a 6-blade, 40 mm conical burr set—and a powerful 6 Nm torque motor, Opus ensures rich, consistent grinds for outstanding flavor in every cup.
Ease at Every Step
Opus makes grinding simple, with a volumetric dosing lid for measuring up to 12 cups, a flip-top grind guide on the load bin lid, and precision adjustments with the inner ring for perfect consistency.
Mess-Free Mornings
Opus’s direct drop-down design minimizes grind retention, while anti-static technology and a spouted catch keep your countertop clean and mess-free.
What does the “+” in “41+ adjustable settings” mean?
Opus has 41 main settings on the outer adjustment ring, numbered from 1 to 11 with 4 minor increments between each, allowing for 0.25-level adjustments. This gives Opus 120 precise grind positions. The inner blue ring beneath the load bin fine-tunes these increments even further—that’s the “+” in “41+”!
What does the inner adjustment ring do, and how do I use it?
The inner adjustment ring on Opus allows for precise grind size adjustments beyond the outer ring. Here’s how it works:
- Outer Ring: Visible when looking directly at Opus, this ring has numbered settings from 1 (finest) to 11 (coarsest), with 4 minor increments between each setting, providing up to 120 grind positions.
- Inner Ring: Located inside Opus, this ring enables micro-adjustments. By adjusting it, you can shift the outer ring’s range, making 1 adjustment on the inner ring equal to 2/3 of an outer increment.
To use the inner ring:
- Empty Load Bin: Ensure it’s clear.
- Center Outer Ring: Rotate it to setting 6.
- Remove Load Bin: Twist counterclockwise and lift away to access the inner ring.
- Press Down: Compress the tabs on the inner ring to enable adjustment.
- Rotate: Adjust the inner ring to fine-tune your grind setting (counterclockwise for finer, clockwise for coarser).
- Engage: Release the calibration ring and check that it rotates with the outer ring.
- Reinstall Load Bin: Ensure it's seated properly for safety and operation.
The inner ring can also expand Opus’s grind range and calibrate for burr wear over time.
How do I clean and maintain Opus?
To ensure optimal performance and longevity of your Opus grinder, follow these cleaning and maintenance steps:
- Exterior: Use a non-abrasive damp cloth to wipe down the exterior and load bin.
- Exit Chute/Anti-Static: Clean the exit chute every 60 cycles for peak anti-static performance. Remove the catch cup and use the Fellow cleaning brush (or a clean makeup/paint brush) to gently “swipe” around the inside of the exit chute.
- Burrs: To clean the burrs, remove the load bin, take off the outer burr, and brush the burrs with the Fellow cleaning brush (or a clean makeup/paint brush).
Regular maintenance will help keep Opus functioning at its best!
