The only infection we can age is the one inflicted by the farmer, which in this case was three years prior to harvest. It is important to note that this tree was not harvested because the infection was three years old, but rather because the tree was moribund and about to die. If you watch the video pertaining to that particular harvest, you will see a comparison between a hardy tree that has managed to cure itself, and this tree. Each tree is different in its constitutional makeup and vigor, and will be able to react differently to different traumas or diseases. Once a tree dies, however, all the resin turns to decay and no oil can be extracted from it.
We had two batches of Sarawak Experiment, one soaked, the other unsoaked. The soaked batch was soaked in plastic.
