Grind Settings Overview
1-3 (Finest)
Pour-over, very fine grindsExtraction: Slower, more resistance
Notes: Optimized for pour-over brewing
4-8 (Fine to Medium)
Most pour-over methodsExtraction: Target 3-4 minutes
Notes: Good starting point for most users
9-15 (Medium to Coarse)
French press, drip coffeeExtraction: Faster flow
Notes: Prevents over-extraction
16-41 (Very Coarse)
Cold brew onlyExtraction: Very fast flow
Notes: Not suitable for espresso
How to Dial In
Start at Setting 6
Why: Middle ground for Fellow's range
Adjust: Go finer if too fast, coarser if too slow
Brew a Cup
Why: Observe extraction time and flow
Adjust: Target 3-4 minutes for pour-over
Assess Flow
Why: Fast flow = too coarse, slow flow = too fine
Adjust: Change 1 setting at a time
Taste Test
Why: Sour = under-extracted, bitter = over-extracted
Adjust: Finer for sour, coarser for bitter
Document Settings
Why: Different beans need different settings
Adjust: Note what works for each coffee
Bean-Specific Settings
Light Roast
4-6 (Finer)Dense beans need finer grind for proper extraction
Medium Roast
6-8 (Standard)Good starting point, adjust to taste
Dark Roast
8-10 (Coarser)Oils extract quickly, coarser prevents bitterness
Fresh (1-2 weeks old)
Standard or slightly coarserFresh beans have more CO2, may need adjustment
Older (3-4+ weeks)
Finer than usualCompensate for degassing with finer grind
Troubleshooting
❌ Brew runs too fast (under 2 minutes)
Cause: Grind too coarse
Solution: Decrease grind setting by 1-2 numbers
❌ Brew runs too slow (over 5 minutes)
Cause: Grind too fine
Solution: Increase grind setting by 1-2 numbers
❌ Weak coffee
Cause: Under-extraction from too coarse grind
Solution: Decrease grind setting, increase brew time
❌ Bitter taste
Cause: Over-extraction from too fine grind
Solution: Increase grind setting, reduce brew time
❌ Sour taste
Cause: Under-extraction from too coarse grind
Solution: Decrease grind setting
❌ Inconsistent extraction
Cause: Uneven grind distribution
Solution: Stir grounds before brewing
