The note, when skillfully rendered, presents an intriguing olfactory tapestry often described as damp, cool, and earthy, with subtle nuances of decomposition and fertile soil. It possesses a textural quality, almost velvety or fuzzy on the olfactory palate, akin to touching aged, damp velvet. Its initial impression can be a cool, slightly mineralic petrichor-like opening, quickly deepening into a rich, humid earthiness. There's an underlying mustiness, not necessarily unpleasant, but rather redolent of ancient cellars or forgotten libraries after a heavy rain. Projection is typically intimate to moderate, creating a distinct aura rather than a pervasive cloud. Its longevity is remarkable, often acting as a tenacious base note or a lingering heart accord, allowing its complex character to unfold over many hours, transforming from a raw dampness to a sophisticated, grounding musk.
