Understanding the vanilla processing journey from harvest to export helps buyers appreciate the quality and care that goes into every bean. Here's how Indonesian vanilla is processed.
Harvest
Vanilla harvesting in Indonesia:
- Beans hand-picked at peak maturity (7-9 months after flowering)
- Harvested during dry season (May-September)
- Each bean carefully selected for quality
- Processed within 24 hours of harvest
Killing
The first step in processing:
- Beans dipped in hot water (65-70°C) for 2-3 minutes
- Stops vegetative growth and begins enzyme activity
- Beans turn from green to brown
Sweating
Critical for flavor development:
- Beans wrapped in wool blankets or stored in sweating boxes
- Temperature maintained at 45-65°C for 24-48 hours
- Enzymes break down, releasing vanillin precursors
- Process repeated daily for several days
Sun Drying
Slow drying develops flavor:
- Beans laid out in sunlight during the day
- Brought inside at night to prevent moisture reabsorption
- Process continues for 2-4 weeks
- Beans lose 60-70% of their moisture
Conditioning
Final flavor development:
- Beans stored in sealed containers for 2-3 months
- Moisture equalizes throughout the bean
- Vanillin content increases to final levels
- Flavor matures and deepens
Grading
Quality classification:
- Grade A: 15-20 cm, 25-35% moisture, 1.3-2.7% vanillin
- Grade B: 10-16 cm, less than 25% moisture, 1.3-2.2% vanillin
- Visual inspection for defects
- Moisture and vanillin testing
Packaging and Export
Final preparation for shipment:
- Beans vacuum-sealed or packed in airtight containers
- Labeled with grade, weight, and origin
- Stored in climate-controlled environment
- Exported via air or sea freight from Indonesian ports
