The note of Oud Assam is an experience of profound depth and unapologetic intensity. It presents an initial challenging and almost feral character, often described as a barnyard, fecal, or animalic growl that quickly mellows into something majestically complex. Its texture is akin to aged leather, dark wood, or a dense, ancient resin. It carries facets of smoky campfire, cured tobacco leaves, and sometimes a hint of dried fruit or stewed prunes beneath its primal core. There's an undeniable woody backbone, often reminiscent of ancient, petrified timber, interwoven with leathery and subtly sweet, balsamic undertones. It possesses a medicinal edge, like a deeply concentrated herbal elixir, and a distinct earthy, rooty quality. Its projection is typically enormous, announcing its presence with authority, and its longevity is legendary, clinging to the skin and fabric for days, evolving from its initial raw power into a sophisticated, warm, and deeply resonant hum. It functions primarily as a base note, anchoring compositions with an almost eternal presence, though its most vivid and challenging facets can reveal themselves strongly in the heart.
