The Story of Oud: Ancient Resin, Timeless Fragrance

Oud comes from the Aquilaria tree, native to the rainforests of Southeast Asia — including regions in India, Bangladesh, Cambodia, and Vietnam. Not every tree produces the prized resin. In the wild, only a small percentage form oud naturally, when the tree is wounded or infected by a specific mould. In response, the tree defends itself by secreting a dark, fragrant resin that saturates the heartwood, turning pale, odourless wood into dense, aromatic agarwood.

Today, sustainable cultivation often involves carefully wounding the trees and introducing the fungus to encourage resin formation, helping meet demand while protecting wild populations.

The Name and Its History

The name "oud" is simple and evocative: in Arabic, it means "wood." Over time, the term came to refer specifically to fragrant agarwood. "Agarwood" itself derives from ancient Sanskrit and Hindi roots (aguru or agar), reflecting its long history in Indian and Eastern traditions. In older English translations of the Bible, it appeared as "aloes" or "lign-aloes" — literally "wood of the aloes" — a linguistic bridge linking the aromatic wood to a more familiar name.

When we think of biblical aromatics, frankincense and myrrh often come first. Yet the Scriptures also speak of "aloes" — a fragrant wood valued for its rich scent in garments and anointing oils. Many scholars identify these biblical aloes with the resinous heartwood we now call oud or agarwood.

How Oud Is Distilled

Creating oud oil is a labour-intensive art. Once the resinous wood is harvested, it is chipped or powdered, soaked, and sometimes fermented to release its compounds. The material then undergoes steam distillation or traditional hydro-distillation — processes that can take many hours or even days. The result is a small yield of thick, precious essential oil: from dozens of kilograms of wood, only millilitres of pure oud may emerge. This low yield, combined with the rarity of high-quality resin, makes oud one of the most expensive and revered ingredients in perfumery.

The Scent of Oud — and its connection to Sandalwood

Oud's aroma is complex and multifaceted: deeply woody and resinous, with smoky, earthy, leathery, and slightly animalic facets. Depending on origin and processing, it can reveal sweet, balsamic, or spicy undertones — a scent that feels both ancient and luxurious, lingering on the skin with remarkable persistence.

While distinct from sandalwood, oud shares a natural kinship with it. Both are prized woody fragrances used for centuries in incense, oils, and perfumes. Sandalwood offers a creamy, smooth warmth — calming and elegant. Oud brings darker depth, richness, and intensity. Together, they complement each other beautifully, creating balanced, sophisticated blends.

Oud continues to symbolise transformation: a tree's wound turning into something beautiful and enduring. When worn as a refined cologne like our Gentlemen's Club Oud & Bergamot, it opens with an uplifting citrus brightness from the bergamot, before settling into a deep, almost sacred woody base that keeps evolving and deepening on the skin.
