Fellow Opus Conical Burr Coffee Grinder

The Fellow Opus is the all-purpose burr grinder that does everything well — from dialling in tight espresso shots to grinding coarse for cold brew — in one compact, beautifully designed machine. Built around a 6-blade, 40mm conical burr set and 41 grind settings, the Opus delivers consistent, flavourful grinds across the full spectrum, with the thoughtful details that Fellow is known for: a magnetic catch cup, a hopper lid with a built-in grind setting guide, and anti-static technology that keeps your counter clean.

Whether you're an everyday home brewer looking for your first serious grinder or an espresso enthusiast who also brews filter on the weekends, the Fellow Opus is designed to handle both without compromise.

Why Choose the Fellow Opus?

Fellow built the Opus as a genuinely versatile grinder — not a filter grinder that can technically do espresso, or an espresso grinder that struggles with coarser settings. The 41-setting grind range is tuned to perform reliably across the full spectrum, and the 6-blade conical burrs are engineered for grind consistency that punches well above the Opus's price point.

• 6-blade, 40mm conical burr set — engineered for consistent particle size and flavourful extractions from espresso to cold brew
• 41 grind settings — wide range covering fine espresso, AeroPress, pour-over, drip, French press, and cold brew
• Anti-static technology — reduces static and grounds retention for a cleaner, less messy grinding experience
• Magnetic catch cup — snaps securely in place during grinding, no sliding or tipping
• Hopper lid with built-in grind setting guide — tells you which setting to use for each brew method, right on the lid
• Compact, counter-ready design — solid footprint designed to live permanently on your worktop
• Intuitive single-button operation — press once to grind, double-press to clear remaining grounds from the burrs
• Available in Matte Black and White — minimalist Fellow aesthetic that complements any kitchen

Who Is the Fellow Opus For?

The Fellow Opus sits at a sweet spot in the market — enough precision and grind range for serious home espresso, but approachable and versatile enough for everyday filter brewing. It's ideal for:

• Home baristas who brew multiple methods and want one reliable grinder that handles everything from espresso to French press
• Espresso drinkers upgrading from a blade or entry-level burr grinder who want consistent, cafe-quality grinds at home
• Filter coffee enthusiasts who want genuine grind precision for pour-over, AeroPress, or drip without spending on a dedicated filter-only grinder
• Gift buyers looking for a premium, stylish coffee upgrade that any home brewer will love and use daily

What Makes the Fellow Opus Different?

Most grinders at this price point compromise somewhere — either the burrs aren't precise enough for espresso, or the grind range doesn't extend coarse enough for cold brew. Fellow engineered the Opus to avoid this trade-off entirely.

The 6-blade conical burr geometry delivers consistent particle size across all 41 settings, which means whether you're pulling espresso or brewing a cafetière, you're getting a grind that extracts evenly. Add the anti-static system, the magnetic catch cup, and the hopper lid grind guide, and the Opus is simply more considered than anything else at this price.

Frequently Asked Questions

Can the Fellow Opus grind for espresso? Yes. The Opus is designed to grind across the full spectrum from fine espresso to coarse cold brew. Its 41 settings include a fine range suitable for dialling in espresso on most home machines. It is worth noting that for very high-end espresso machines requiring ultra-fine micro-adjustment, a dedicated espresso grinder may offer more precision — but for the vast majority of home espresso setups, the Opus performs excellently.

What is the grind range of the Fellow Opus? The Opus has 41 grind settings covering the full spectrum from fine espresso through AeroPress, pour-over, drip coffee, French press, and cold brew. The hopper lid includes a built-in grind setting reference guide to help you find the right starting point for each brew method.

What are the 40mm conical burrs in the Fellow Opus? The Opus uses a 6-blade, 40mm conical burr set specifically designed by Fellow for consistent particle size distribution across all grind settings. The 6-blade design increases the number of cutting edges compared to standard conical burrs, improving grind uniformity and extraction consistency.

Does the Fellow Opus have anti-static technology? Yes. The Opus includes anti-static features that reduce the static charge in ground coffee, which helps keep grounds in the catch cup rather than clinging to surfaces. Several reviewers have noted that a light spritz of water on beans before grinding (the Ross Droplet Technique) further reduces static if needed.

What is the magnetic catch cup for? The catch cup uses a magnet to snap securely onto the grinder body during use, preventing it from sliding or tipping while you grind. This makes the workflow faster and more reliable, especially when grinding directly into a portafilter adapter or dosing cup.

How do I clear remaining grounds from the Fellow Opus? A double-press of the grind button activates a short clearing cycle that purges any remaining grounds from the burr chamber. This is particularly useful when switching between beans or adjusting grind size.
