Processing the peppercorns after harvest is not straight forward. The berries have to be separated first into red and green, removing the poor quality ones. Berries that are not fully red or are fully grown but a little bit damaged can still be made into white pepper. The three sets of berries then need to boiled for a very precise time – too long or too short can compromise their drying to the correct colour and density – before being laid out to dry in the sun for up to a week, depending on cloud cover. While drying, the berries need to be periodically raked to turn them over and let the air in.
