Learn how to dial in the Fellow Opus 2 grinder for any brew method. Follow these steps for consistent grinds from espresso to cold brew.
Quick Answer
To get consistent grinds from the Opus 2, first set the grind size using the 41 settings, then use single-dose loading and the timed autostop to control your brew.
Why Grind Consistency Matters
Consistent grind size is the key to even extraction. If your grind is uneven, some particles over-extract while others under-extract, leading to bitter or sour coffee. The Opus 2's conical burrs produce a uniform particle size, which helps you get the most flavor from your beans.
The Opus 2 offers 41 unique grind settings, covering everything from true espresso to the coarsest cold brew. This wide range means you can use the same grinder for all your brewing methods, but it also means you need to know which setting to choose.
Step-by-Step Guide to Consistent Grinds
- Set the grind size: Turn the adjustment ring to your desired setting. For espresso, start near the finest settings; for pour-over, use a medium setting; for cold brew, go coarse. Check the included guide for recommended ranges. Always start with the recommended range and adjust from there based on taste.
- Load a single dose of beans: Weigh your coffee beans and add them to the hopper. Single-dose loading ensures you grind only what you need, which keeps the grind fresh and consistent. Using a scale helps you repeat the same dose every time.
- Use the timed autostop: Set the timer to match your dose size. The grinder will stop automatically, so you don't have to watch it. For a more precise control, you can also use the manual pulse button. Adjust the timer if you change your dose or brew method.
- Collect the grounds in the magnetic catch cup: Place the magnetic catch cup under the chute. The magnet holds it securely, and the anti-static technology reduces clumping and mess. Tap the cup gently to settle the grounds before brewing.
