Agarwood, or oud, is the most expensive note in a perfumer’s palette. It has been valued for thousands of years and is considered one of the most luxurious ingredients in the world of perfumery. Oud is derived from the dark resin of the Agar tree, which grows in very rare conditions. Although its popularity skyrocketed in the past decade, oud has been known and used by various ancient civilizations in esoteric ceremonies and meditation practices for hundreds of years. Perfect for cold weather, oud has a distinctively woody, slightly animalic, and rich scent. Oud’s warmth adds whole new brevity and depth when combined with floral or spicy notes.
