The note of "Wood Decay" is a profound olfactory experience, far from the crisp, clean scent of fresh-cut timber. It is a deep, earthy, and profoundly humid aroma, reminiscent of a forest floor after a long rain. Its initial impression can be surprisingly subtle, a whisper of damp soil and decomposing leaves, but it quickly deepens into a rich, musty sweetness, almost fungal or mushroom-like. There's a distinct petrichor quality, the scent of rain on dry earth, intertwined with the soft, crumbly texture of decaying wood. It lacks sharp edges, instead presenting a rounded, velvety, almost mossy character. Its intensity is moderate, never overwhelming, but its projection is intimate, drawing the wearer and those close into its quiet embrace. As it evolves, it becomes more grounded, revealing subtle hints of damp earth, a faint, sweet rot, and a lingering, almost mineralic undertone. It functions primarily as a heart or base note, providing exceptional longevity and a unique, naturalistic depth to a composition.
