Warehouse storage best practices

Why Warehouse Storage Matters

  • Green coffee is hygroscopic and sensitive to its environment.
  • Poor storage leads to mold, pest infestations, odor contamination, and flavor fade.
  • Specialty buyers demand documented storage protocols.

Climate Control

  • Temperature: 18–22°C (stable, cool conditions).
  • Relative Humidity (RH): 55–65% to maintain 10–12% bean moisture.
  • Avoid rapid fluctuations to prevent condensation and rehydration.

Bag Handling

  • Store bags on pallets or dunnage, never directly on the floor.
  • Leave space between stacks and walls for airflow.
  • Stack bags in stable piles (12–15 bags high maximum).
  • Use hermetic liners (GrainPro, Ecotact) inside jute for specialty lots.

Sanitation & Pest Control

  • Keep warehouse clean, free of dust, old parchment, or organic matter.
  • Seal entry points against rodents and insects.
  • Rotate stock (FIFO – first in, first out) to ensure freshness.
  • Inspect regularly for mold, pests, or bag damage.

Inventory Management

  • Maintain detailed records with lot codes, arrival dates, and quantities.
  • Separate lots by quality, origin, or certification to prevent mixing.
  • Conduct periodic quality control checks (moisture, cupping).

Risks of Poor Storage

  • Mold growth → earthy, baggy, or sour flavors.
  • Absorption of odors from chemicals, wood, or other stored goods.
  • Decline in cupping scores over time, leading to price discounts or rejection.

Best Practices for Export Readiness

  • Pre-condition warehouses before storing new harvest.
  • Use desiccants or dehumidifiers in humid climates.
  • Train staff in bag handling and record keeping.

Lasting Importance

Warehouse storage best practices are the final safeguard before export. By maintaining stable climate, clean conditions, and disciplined inventory systems, producers and exporters ensure coffee maintains its flavor, integrity, and value from farm to roaster.
