Grassy/woody notes from age or process

Key Concepts

  • Causes of Grassy/Woody Notes:

  • Coffee stored for too long, leading to staling.

  • Incomplete drying during post-harvest processing.

  • Parchment or bean exposure to high humidity.

  • Poorly executed natural or honey processing, leaving excessive vegetal residues.

  • Sensory Indicators:

  • Tasting notes reminiscent of freshly cut grass or raw wood.

  • Flat or dull flavor profile.

  • Reduced sweetness and fruit clarity.

  • Solutions & Prevention:

  • Properly dry coffee to target moisture before storage.

  • Maintain stable, cool, and dry storage conditions.

  • Rotate stock to prevent long-term aging effects.

  • Adjust processing methods to avoid vegetal overtones.

  • Monitor beans for early signs of staling or off-flavors.

Summary

Grassy or woody flavors often signal issues in processing or storage. Attention to drying, storage environment, and timely roasting helps maintain coffee quality.
