Tar is a dark textured note that can suggest leather, smoke, tobacco, tar, or warm dry materials. It gives fragrance depth, sensuality, and a more dramatic atmosphere. In perfumery, smoky and leathery notes are often used in bases, where they add strength and character without needing sweetness. Tar pairs well with oud, saffron, birch tar, amber, tobacco, rose, patchouli, vetiver, incense, and dry woods.
