From Raw Material to Fragrance: A Guide to Agarwood Processing

Agarwood processing transforms raw agarwood into usable incense products. Key steps include material selection, cleaning, cutting, grinding, blending, shaping, and aging. Proper processing preserves the aroma and enhances quality.

1. Material Selection and Cleaning

The quality of raw agarwood determines the final product grade. The first step is sorting by resin content, origin, and shape. Then, clean the surface by soaking in water and brushing to remove dirt and decayed wood, followed by drying in shade. Avoid damaging resin-rich areas. For high-grade materials like Kyara, cleaning is done manually with care.

2. Cutting and Grinding

After cleaning, cut the material according to use. For making incense sticks or powder, grind agarwood into powder using a grinder or stone mill, controlling temperature to prevent aroma loss. Powder fineness affects burning; 80-120 mesh is typical. For carving or heating, cut into blocks or slices along the grain. More details in the Agarwood Encyclopedia.

3. Blending and Shaping

Agarwood powder is often blended with other spices or used alone to make incense sticks or coils. Blending follows incense principles, with binders like machilus bark powder. After shaping, dry in shade. Traditional blending and shaping are key in incense study, see Chinese Incense Study · Identification.

4. Aging and Storage

Shaped incense needs aging in a cool, dry place to stabilize the aroma. Aging ranges from weeks to years. Store in airtight containers away from moisture and odors. Aged incense has a purer scent. Each step requires experience; refer to the Identification Pillar for quality assessment.
