The note is a profoundly grounding and complex olfactory experience, evoking the rich, dark, fertile soil after a heavy rain. Its aroma is deeply earthy, mineralic, and somewhat damp, carrying an almost primordial gravitas. There's a distinct petrichor quality, a clean wetness that permeates the loamy richness. Beyond mere earth, one might discern subtle nuances of decaying leaves, ancient roots, and a faint, mushroom-like spore-y quality. It possesses a velvety, almost viscous texture on the olfactive palate, dense and opaque. The intensity is robust, often acting as a significant anchor in a composition, with moderate to strong projection depending on its concentration. It typically behaves as a heart or base note, evolving slowly to reveal its deep, resonant complexity, grounding more volatile elements and imparting exceptional longevity.
