The note of Elm, rarely extracted directly but rather artfully reconstructed, manifests as a profound, venerable woody presence. It is not bright or sharp, but rather a deep, resonant woodiness, often with a distinctive damp, almost loamy earthiness. Imagine the cool, moist bark of an ancient tree after a soft rain, or the slightly musty, robust aroma of an old growth forest floor. It carries a subtle, green-grey melancholy, reminiscent of petrichor clinging to aged timber. Its texture is smooth, yet gnarled and complex, evoking moss-covered surfaces and deep roots. Intensity is moderate to strong, projecting with a quiet authority rather than an aggressive sillage. Longevity is excellent, grounding a composition for many hours. It invariably behaves as a heart or, more commonly, a base note, providing an anchor of arboreal wisdom.
