What Type of Agarwood or Oud Is Best?

Agarwood, known as oud or oudh, is a deeply aromatic resin found in certain trees and has been celebrated for millennia across various cultures for its rich and compelling fragrance.

When selecting the best type of oud, you’re not just choosing a scent; you’re choosing a piece of heritage—one that varies significantly depending on its origin, the tree species, and the way it’s harvested and processed. Each factor contributes to the unique profile of the oud, which can range from sweet and nuanced to deep and intensely woody.


Regarding what constitutes the finest agarwood, the answer may be quite straightforward: Kyara or kynam. This is a top-grade agarwood, and aside from Kyara, there are other esteemed types such as Pursat agarwood, sinking agarwood, and red soil agarwood.

These four types are considered the most elite categories of agarwood. In this article, I will introduce you to the culture, origins, appearance, and scents of these four types of agarwood. Of course, I will also discuss their market prices.

What is Agarwood?

The Origins of Agarwood

Agarwood is a valuable wood type formed in the heartwood of Aquilaria trees, a natural response to fungal or bacterial infection. When the tree is compromised, it secretes a fragrant resin to encapsulate the attack, which results in the dark, dense, and aromatic heartwood.

So, in a strict sense, agarwood isn’t wood. It’s more described as a resin.

The primary sources of agarwood are now in Southeast Asia, specifically Vietnam, Cambodia, Malaysia, and Hainan. Most of them are cultivated artificially, and it is quite difficult to find pure, natural, wild agarwood nowadays.

Aquilaria Species and Agarwood

There are several species of the genus Aquilaria, each capable of producing the resin that becomes Agarwood. However, not all Aquilaria trees create this resin; the process begins only when the tree is infected with a specific type of mold.

Agarwood Tree

The most sought-after Agarwood comes from mature trees that have had time to develop the resin, with over a dozen identified species of Aquilaria known to produce it.

The rarity of oud is compounded by the fact that Aquilaria trees are becoming increasingly scarce due to overharvesting and habitat loss, making the occurrence of natural agarwood even less common. As a result, genuine agarwood is hard to find and commands very high prices in the market.

How to Grade Agarwood

Several key indicators, including the resin concentration, wood color, and scent profile, determine agarwood quality. High-grade oud, for example, like Kyara or kynam, is densely packed with resin, translating into a darker color and a richer, more complex scent. known for its distinct and highly sought-after fragrance.

Grading Indicators

The grading systems for agarwood, such as the Alphabetic Grading System, Water Grading System, and Resin Saturation Grading System, are commonly used in countries that are major producers and consumers of agarwood. These countries typically include those within Southeast Asia, where agarwood is naturally found and culturally significant.

  • Alphabetic Grading System: Ranges from C to AAA, with AAA being the top grade. This system takes into account the agarwood’s characteristics and overall quality.
  • Water Grading System: Includes terms such as Semi-Sinking, Sinking, and Underwater, which refer to the agarwood’s density and resin content.
  • Resin Saturation Grading System: From Super to Triple Super, this indicates the level of resin in the wood.

Historically, these ceremonies have elevated the use of Kyara to a sophisticated art, appreciating its complex scent through a ritual called “listening to incense.” Kyara’s rarity and the depth of its fragrance have made it a luxurious commodity, often compared in value to gold. In contemporary Japan, possessing and utilizing Kyara is a symbol of wealth and taste, continuing the tradition of its esteemed cultural status.

Besides medicine and incense, Agarwood is also used in fine craftsmanship. It is carved into intricate sculptures, beads, and other ornamental objects. These items are often used in personal accessories such as bracelets and necklaces; they believe it can bring good luck and health.

Origins and Market Value

Kyara agarwood primarily originates from regions such as Hainan, Vietnam, Cambodia, and Malaysia. Historically, Hainan Kyara was considered the finest quality and was widely recognized.

However, due to centuries of harvesting, natural Kyara has nearly vanished from Hainan. Nowadays, the industry acknowledges Nha Trang in Vietnam as the premier region for the best Kyara.

Although Kyara is produced in other regions, variations in climate, temperature, humidity, and fungal species result in somewhat inferior quality, with shorter fragrance retention upon burning and less complexity in its olfactory notes.

Genuine wild white Kyara has almost become extinct and is difficult to obtain. At a 2019 auction in Yokohama, a 2100g piece of wild Nha Trang white Kyara was sold for 1.81 million USD, which equates to around 1000 USD per gram.

What is Sinking Grade Agarwood

Sinking grade agarwood is distinguished by its ability to sink in water, a quality resulting from its high resin saturation. Harvested in the Hainan province, this type of agarwood is the result of a natural process involving the Aquilaria tree. When these trees become infected by a particular mold, they produce an oleoresin to combat the infection, which eventually permeates the heartwood.
