The note of Thorn doesn't present itself as a singular botanical extract, but rather as an evocative olfactory construct designed to convey a sensation: a sharp, green, almost metallic edge that pricks the senses. It possesses an initial piercing quality, akin to the precise point of a needle or the crisp snap of a twig, followed by an underlying dry, woody, and slightly austere verdancy. There's an inherent rawness, a verdant bitterness that hints at the sap of a plant's defenses, often accompanied by a subtle, cool, mineralic undertone. Its texture is decidedly spiky, not smooth or lush, evoking the rigid structure of a stem. Intensity can vary; it can be a fleeting, sharp top-note 'prick' designed to awaken, or a sustained, almost melancholic heart-note providing structure and tension. Its projection is typically moderate, designed to intrigue rather than overwhelm, and its longevity depends on the specific chemical components of the accord, often settling into a persistent, dry green woody base.
