Agarwood Grade System: From Bantou and Diaokou to Kyara

The agarwood grade system classifies agarwood by formation part and morphology, from common grades like Bantou and Diaokou to the top-grade Kyara. This article systematically explains the characteristics and identification points of each grade to help you build a clear understanding of agarwood levels.

1. Core Logic of Agarwood Grading

Agarwood grading is not a single standard but a system formed by multiple dimensions such as formation part, morphology, resin content, and aroma performance. Traditionally, based on the formation part and appearance, agarwood can be divided into major categories including Bantou (board-like), Diaokou (hanging mouth), Jugkou (saw cut), Kechen (shell), Chonglou (insect leak), and Kyara. Among them, Bantou refers to the part where large-area resin formation occurs after the tree is injured, often in board shape; Diaokou refers to the resin that hangs downward after the trunk is injured, shaped like a pendant. These categories differ significantly in resin density and aroma layers, forming a complete spectrum from entry-level to top-grade. Understanding this spectrum is the first step into agarwood appreciation. For a complete framework of agarwood formation mechanisms and classification, please refer to the Agarwood Encyclopedia.

2. From Bantou to Diaokou: Characteristics and Identification of Common Grades

Bantou agarwood is mostly taken from the injured surface of the trunk or large branches. It has a large resin formation area but uneven resin distribution, often with wood fibers, and its aroma is relatively light and simple, suitable for beginners' daily enjoyment. Diaokou agarwood, due to gravity during resin formation, has resin gathering downward, with relatively higher density and a more intense aroma than Bantou, but still belongs to the common grade. When identifying, pay attention to whether the resin lines are clear and the color is natural, and you can judge the purity and persistence of the aroma by heating and smelling. For authenticity identification of Bantou and Diaokou, you can refer to the systematic methods in the Identification Pillar Page. In addition, Jugkou agarwood (resin formed on saw cuts) and Kechen (resin formed on bark) are also common grades with their own characteristics.

3. Kyara: The Pinnacle of Agarwood Grades

Kyara is the top-grade category of agarwood. Its resin formation mechanism differs from ordinary agarwood; it is soft and waxy, rich in resin, has a numbing and spicy sensation in the mouth, and its aroma is multi-layered, often with coolness, floral, and fruity notes. Kyara can be classified by color and origin into White Kyara, Green Kyara, Purple Kyara, Yellow Kyara, and Black Kyara, among which White Kyara is particularly rare. The grading of Kyara focuses on aroma explosiveness, persistence, and mouthfeel rather than mere resin density. Due to extremely low yield, there are many imitations on the market, and identification requires microscopic structure, aroma characteristics, and professional experience.

4. Practical Application of the Grade System and Collection Advice

In actual collection and appreciation, the agarwood grade system helps enthusiasts establish a value judgment framework: Bantou and Diaokou are suitable for daily incense or entry-level collection; Kechen and Chonglou are also favored by players for their unique shapes; Kyara belongs to top-level collectibles and requires careful identification. It is worth noting that grades are not absolute; there are high and low within the same category, requiring comprehensive consideration of resin, aroma, and morphology. It is recommended that enthusiasts start with common grades, gradually accumulate experience, and then venture into high-end categories.

Conclusion

The agarwood grade system, from Bantou and Diaokou to Kyara, reflects the progressive relationship between formation part and quality. Mastering this system not only improves identification ability but also allows you to appreciate the rich layers of the agarwood world. Whether you are a beginner or advanced, systematic learning and physical comparison are essential paths.
