The note of green sap unfolds with an immediate, piercing freshness, a vibrant, almost electric scent that speaks of verdant life force. It is distinctly vegetal, a crisp, slightly bitter aroma that evokes the snapping of a succulent stem or the tearing of a broad, dewy leaf. There's a subtle aqueous quality, a 'wet green' aspect that is both cool and clean, reminiscent of morning dew clinging to unfurling foliage. Its texture is almost palpable: sharp at first, then softening to a smooth, verdant verdancy. It possesses a moderate intensity, lending an airy spaciousness to a composition without being overwhelmingly heavy. As a top to mid-heart note, it projects with a lively, invigorating burst, offering an initial effervescence before settling into a more composed, still-fresh greenness. It can sometimes carry a fleeting hint of metallic luminescence, like the glint of sunlight on a freshly cut plant, or a powdery-green undertone that suggests the inner life of the plant, rather than just its surface.
