The sandalwood tree is felled in the forest and the sapwood is removed before delivery to the distillery, as only the heart is rich in essential oil.
The wood is stocked for drying then milled to become woodchips. The chips are then placed in a double boiler heated by a wood fire, whose steam allows the wood to exude its essential oil. The next step is the cooler which gives a water and oil mixture. The last step is to use an ‘essencier’ or Florentine vase to separate the oil and the water by density. Once filtered, the oil is very pure.
