The note of tree sap presents a complex olfactory tapestry, often beginning with a sharp, verdant bite that is immediately followed by a sticky, viscous sweetness. Its initial impression is distinctly green and resinous, reminiscent of snapping a fresh twig or the pungent aroma emanating from a wound in tree bark. This greenness can vary from bright, almost lemony-pine (like fir or spruce sap) to a darker, more camphoraceous green. As it evolves, the stickiness deepens, transforming into a warm, balsamic richness, akin to amber or labdanum, but with an inherent, earthy dampness that distinguishes it. The texture it evokes is undeniably oily, thick, and syrupy, almost tactile in its representation of natural exudate. Its intensity is typically moderate to strong, with excellent longevity, anchoring a composition as a tenacious heart or base note. Projection is often steady and enveloping, creating an aura of sylvan depth and grounded warmth.
