The note is a profoundly complex and multifaceted olfactory experience, often described as a dark, rich, and intensely woody aroma, intertwined with leathery, smoky, animalic, and resinous facets. Its texture can feel almost tactile: velvety, smooth, yet with sharp, almost medicinal edges. Initially, it can present with a startlingly strong, even challenging barnyard or fecal quality, which quickly evolves into a deeply spiritual, balsamic sweetness. Projection is typically immense, commanding a room, while its longevity is legendary, clinging to skin and fabric for days. As a true base note, it anchors a composition, unfolding slowly over many hours, revealing layers of dark honey, dried fruit, tobacco, and an intriguing whisper of damp earth or ancient parchment. There are variations, from bright, leathery Cambodian oud to sweeter, more medicinal Vietnamese, and intensely animalic Indian varieties.
