The note of Green Pith unveils itself with an immediate, bracing sharpness, a verdant clarity that is strikingly distinct from the lush sweetness of leafier greens or the juicy succulence of fruit pulp. It is acutely bitter, possessing an almost tactile dryness that suggests the chalky interior of citrus rind, stripped bare of its oil sacs. Imagine the precise moment a grapefruit or lime is peeled, and the finger scrapes against the white, fibrous layer beneath the zest – that is its essence. The initial impression is intensely fresh, somewhat astringent, and almost peppery, with a cool, airy quality. It projects with assertive confidence in its opening, acting predominantly as a top or upper-heart note. As it evolves, it softens slightly, shedding some of its initial ferocity to reveal a more subdued, herbaceous, and almost woody-dry green nuance, settling into a clean, enduring presence without ever becoming heavy or sweet. Its longevity is moderate, fading gracefully to leave a crisp, verdant echo.
