A green vanilla pod has almost no vanilla aroma. Everything buyers value is created during curing — a slow process that can take months.
1. Killing
Freshly harvested pods are briefly treated with hot water or sun heat to stop the pod’s growth and start the enzymatic reactions that develop flavour.
2. Sweating
Beans are wrapped in cloth and kept warm so they sweat. This is when the beans turn brown and vanillin starts to form.
3. Slow drying
Beans are sun-dried for a few hours each day and brought inside at night, gradually reducing moisture to the level required for the target grade.
4. Conditioning
Finally, beans rest in closed boxes for weeks or months so the aroma can round out. They are then sorted by length and grade, bundled and packed.
Consistent curing is what separates a great lot from an average one, and it is where working closely with growers matters most.
