Agarwood Aroma Type Atlas: Sweet, Cool, Floral, Fruity, Medicinal, Milky

Agarwood aromas can be systematically classified into six types—sweet, cool, floral, fruity, medicinal, and milky—each corresponding to distinct resin formation environments and tree species, serving as a core basis for identification and evaluation.

Why Can Agarwood Aromas Be Divided into Six Types?

The aromatic complexity of agarwood stems from the diversity of aromatic compounds formed by resin and wood under the combined action of microorganisms, time, and environment during resin formation. Based on dominant odor characteristics, the industry typically categorizes agarwood aromas into six basic types: sweet, cool, floral, fruity, medicinal, and milky. These six are not mutually exclusive; most agarwood presents a complex aroma with primary and secondary notes, but the dominant type determines its style and grade. Understanding this atlas is the first step into the systematic knowledge of the Agarwood Encyclopedia.

Specific Characteristics and Representative Origins of the Six Aroma Types

Sweet: The most universal agarwood base note, manifesting as honey, caramel, or brown sugar scents, commonly found in low-to-medium resinous wood from the Hui'an and Sin Chew systems. The purity of sweetness is an important indicator of natural resin formation. Cool: A penetrating coolness similar to mint or borneol, often appearing in aged Hui'an-system woods such as Hainan and Nha Trang; the longer the cool sensation lasts, the denser the resin usually is. Floral: Elegant as orchid or osmanthus, represented by some Hainan and Cambodian woods; floral-type agarwood typically forms in moister environments. Fruity: A sweet-and-sour sensation of ripe fruit or preserved fruit, common in West Malaysia and parts of Kalimantan; fruity notes often accompany sweetness. Medicinal: A herbal bitter scent reminiscent of a Chinese medicine shop, mostly seen in aged Sin Chew-system woods from Indonesia; prominent medicinal notes often indicate longer resin formation periods. Milky: A warm, creamy dairy note, typical of origins like Brunei and Tarakan; milky notes are especially mellow when combined with sweetness.

How to Use the Aroma Atlas to Assist Identification and Evaluation?

In practical identification, the aroma type atlas should be cross-verified with appearance, density, and oil lines. For example, a strong combination of cool and milky notes with high penetration should raise suspicion of artificial oil injection or compression fraud; overly heavy medicinal notes lacking sweetness may indicate abnormal resin formation environment or improper storage. For evaluation, it is recommended to combine room-temperature raw scent and heated fumigation, recording changes in aroma types across top, middle, and base notes.

Key Takeaways

The six aroma types—sweet, cool, floral, fruity, medicinal, and milky—form the flavor coordinates of agarwood. A single type is rare; complex aromas are the norm. Mastering the primary-secondary relationships and origin correspondence can significantly improve the accuracy of selection and identification. It is advisable to keep personal aroma notes, recording type combinations and rhythm of changes for each piece; long-term accumulation will form a reliable olfactory judgment system.
