Production of Vanilla

Harvest
The pods are harvested while green and immature. At this stage, they are
odourless.
Killing
The vegetative tissue of the vanilla pod is killed to prevent further
growing. The method of killing varies, but may be accomplished by sun killing,
oven killing, hot water killing, killing by scratching, or killing by freezing.
Sweating
The pods are held for 7 to 10 days under hot (45º-65ºC or 115º-150ºF) and
humid conditions; pods are often placed into fabric covered boxes immediately
after boiling. This allows enzymes to process the compounds in the pods into
vanillin and other compounds important to the final vanilla flavour.
Drying
To prevent rotting and to lock the aroma in the pods, the pods are dried.
Often, pods are laid out in the sun during the mornings and returned to their
boxes in the afternoons. When 25-30% of the pods' weight is moisture (as opposed
to the 60-70% they began drying with) they have completed the curing process and
will exhibit their fullest aromatic qualities.
Grading
Once fully cured, the vanilla is sorted by quality and graded.
