How to Use the Fellow Opus 2 Grinder: Settings for Every Brew Method

The Fellow Opus 2 Grinder has quickly become a favorite among home baristas for its versatility and sleek design. Whether you're brewing a delicate pour over or a rich espresso, the Opus 2 offers 41 grind settings that allow you to dial in the perfect particle size for any method. But with so many options, knowing where to start can be overwhelming.

In this guide, we'll walk you through the ideal grind settings for the most popular brew methods, from espresso to cold brew. We'll also share tips on how to adjust based on taste, so you can get the most out of your Fellow Opus 2 Grinder and enjoy consistently delicious coffee at home.

Understanding the Fellow Opus 2 Grinder Settings

The Fellow Opus 2 features 41 click-based grind settings, ranging from 1 (finest) to 41 (coarsest). This wide range makes it suitable for everything from Turkish coffee to French press. The grinder uses 40mm conical burrs, which produce uniform particles and minimal fines, ensuring a clean extraction. The adjustment ring is easy to turn, and the grind size indicator helps you quickly find your desired setting.

Before you start, it's important to note that grind settings are a starting point. Factors like bean freshness, roast level, and water temperature can affect extraction. Always taste your coffee and adjust accordingly. The Opus 2's stepless micro-adjustment (within each click) allows for fine-tuning, though most users will find the click settings sufficient.

• Setting 1-5: Turkish / ultra-fine (not commonly used for drip coffee)
• Setting 6-10: Espresso (fine, powdery)
• Setting 11-15: AeroPress (fine to medium-fine)



• Setting 16-22: Pour over (medium-fine to medium)
• Setting 23-30: Drip machine / Chemex (medium to medium-coarse)
• Setting 31-35: French press (coarse)
• Setting 36-41: Cold brew (extra coarse)

Espresso Grind Settings for the Fellow Opus 2

For espresso, you want a fine, consistent grind that offers resistance to water pressure. Start at setting 8 and pull a shot. If the shot runs too fast (gushes out in under 20 seconds), grind finer (lower number). If it drips slowly or chokes the machine, grind coarser (higher number). The ideal shot time is 25-30 seconds for a 1:2 ratio (e.g., 18g in, 36g out).

The Fellow Opus 2 pairs beautifully with espresso machines like the Sage Barista Touch Impress. Its precise grind consistency helps you achieve balanced extraction with rich crema. Remember to purge a few grams of coffee after changing settings to clear the burrs of previous grounds.

• Starting point: Setting 8
• Adjust by 1-2 clicks based on shot timing
• For light roasts, you may need finer (6-7); for dark roasts, coarser (9-10)

Pour Over Grind Settings for the Fellow Opus 2

Pour over brewing requires a medium-fine grind, similar to table salt. Start at setting 18 for a standard V60 or Kalita Wave. The water should take about 2.5-3 minutes to drain through. If the brew stalls or tastes bitter, grind coarser (20-22). If it runs too fast and tastes sour, grind finer (16-17).

For those who want to master pour over at home, the Home Filter Coffee Brewing Course in London offers hands-on training that complements your grinder skills. Using the Opus 2, you can easily replicate the grind consistency taught in professional courses.

• Starting point: Setting 18 (medium-fine)
• Brew time target: 2.5-3 minutes
• Adjust based on taste: sour = finer, bitter = coarser

Cold Brew and French Press Settings

Cold brew and French press require a coarse grind to avoid over-extraction and sediment. For cold brew, use setting 38-41, which produces very coarse particles. Steep for 12-24 hours at room temperature or in the fridge. The result is a smooth, low-acid concentrate that can be diluted with water or milk.

For French press, setting 33-35 works well. The coarse grind allows the plunger to filter easily and prevents a muddy cup. Steep for 4 minutes, then press slowly. If your coffee tastes bitter or has too much sediment, try a slightly coarser setting next time.

• Cold brew: Setting 38-41 (extra coarse)
• French press: Setting 33-35 (coarse)
• Steep times: cold brew 12-24 hrs, French press 4 mins

Tips for Dialing In Your Fellow Opus 2 Grinder

Always use fresh, high-quality beans and weigh your dose for consistency. The Opus 2's grind-by-time feature is convenient, but weighing your output ensures accuracy. Clean the grinder regularly by brushing the burrs and using the included cleaning tablets to prevent oil buildup.

Keep a brew log to track settings, dose, and taste notes. Over time, you'll develop a intuition for how different beans respond to grind adjustments. The Fellow Opus 2 is a reliable tool that rewards attention to detail.

• Weigh your coffee before and after grinding
• Clean burrs every 2-4 weeks
• Use a distribution tool like the BT Wedge Coffee Distribution Tool for even extraction in espresso
