Intensely earthy, damp, mineralic, and rooty, the note immediately conjures the profound aroma of freshly turned soil after a long-awaited rain. It possesses a distinct "petrichor" quality, often described as the scent of rain on dry earth, with subtle nuances of mushroom, moss, and a cool, almost metallic dampness. Its intensity is remarkable, detectable at incredibly low concentrations, and it projects with a quiet yet pervasive presence, often described as a "wet" or "humid" texture. While it can be perceived as a top note due to its immediate impact, its true nature is more akin to a persistent heart or even a base note, lingering for hours, grounding the composition with its primal earthiness. It is not sharp or effervescent, but rather deep, rich, and profoundly grounding.
