Conditioning in parchment

What is Conditioning?

  • Conditioning is the resting period where dried coffee in parchment (10–12% moisture) is stored before hulling.
  • Allows moisture to redistribute evenly inside beans, stabilizing them for storage, milling, and roasting.

Why Parchment Storage?

  • Parchment layer acts as a protective barrier, shielding beans from humidity swings, pests, and odors.
  • Maintains bean integrity until closer to export.

Duration of Conditioning

  • Typically 4–8 weeks.
  • Some specialty lots conditioned longer (up to 3 months) to harmonize flavors.
  • Must be monitored to prevent rehydration or over-drying.

Quality Benefits

  • Moisture equilibrium: Prevents uneven roasting and cup inconsistency.
  • Flavor development: Resting period softens harsh notes, enhances sweetness and clarity.
  • Storage stability: Protects green coffee quality during transit.

Best Practices

  • Store parchment in cool, dry, well-ventilated warehouses.
  • Keep relative humidity <65%.
  • Use pallets to keep bags off the floor.
  • Protect from pests, odors, and direct sunlight.
  • Rotate stock (first in, first out) to maintain freshness.

Risks if Skipped

  • Beans may roast unevenly if moisture not equilibrated.
  • Higher risk of instability, mold, or early quality decline.
  • Reduced ability to meet specialty buyer expectations.

Certification & Traceability

  • Many certifications (Organic, Fairtrade, Rainforest Alliance) encourage proper conditioning as part of post-harvest handling.
  • Documentation of conditioning improves buyer confidence in lot stability.

Lasting Importance

Conditioning in parchment is a vital bridge between drying and hulling. It protects and stabilizes coffee, ensuring that the effort invested in cultivation and processing is preserved all the way to the roaster and cup.
