The note of Rue presents a singularly arresting and complex olfactory profile, often described as sharply green, intensely herbaceous, and distinctly metallic, almost mineralic. It carries a potent bitterness that is both clean and slightly acrid, reminiscent of bruised leaves or a medicinal tincture. There's an underlying animalic nuance, frequently perceived as urinous or civet-like, which adds a challenging depth and a touch of raw earthiness. Its initial projection is strong and almost piercing, a verdant spear cutting through the air, quickly evolving from a bright, almost aldehydic green to a more tenacious, leathery herbal core. While it can begin as a prominent top-to-heart note, its tenacious bitterness and intriguing animalic undertones anchor it firmly into the middle, sometimes even hinting at the base. It possesses a dry, almost dusty texture, far from lush or juicy, with a remarkable longevity that ensures its distinctive character is not easily forgotten. The overall impression is one of stark naturalism, bracing and almost austere, demanding attention rather than merely inviting it.
