Agarwood, also known as oud, is a precious resinous wood note formed when Aquilaria trees develop aromatic dark resin. Its scent can be smoky, woody, leathery, balsamic, animalic, and deeply warm. In perfumery, oud gives power, longevity, and a luxurious Middle Eastern depth to compositions. It can be dark and intense or smooth and polished depending on the quality and blending. Oud pairs beautifully with rose, saffron, amber, incense, sandalwood, patchouli, leather, and musks.
