The note of Soot is a profoundly evocative and complex aroma, often perceived as dry, dark, and intensely smoky. It carries a distinctive charred, almost mineralic quality, reminiscent of extinguished embers or the residual dust within an old fireplace. Its texture on the olfactory palate is particulate, gritty yet surprisingly soft, like fine ash. Initially, it can present with a sharp, almost acrid edge, quickly settling into a velvety, warm embrace. It possesses a moderate to strong projection, especially in its initial stages, evolving to a more intimate, skin-close warmth over time. Its longevity is remarkable, anchoring compositions with its tenacious, dry-woody and phenolic facets. This note typically functions as a robust heart or, more commonly, a deep base note, providing an unparalleled depth, a sense of gravitas, and an almost melancholic warmth to a fragrance.
