Vetiver is a fragrant grass root grown mainly in India, Haiti, and Réunion Island, and it's quietly one of the most-used ingredients in men's perfumery — the kind of note that shows up in half your favorite colognes without ever getting top billing. On its own, vetiver smells like damp earth after rain, a bit of smoke, a bit of wood, with a faint sweetness underneath that keeps it from turning harsh. Some perfumers let it stand alone (Lalique's Encre Noire is the textbook example), while others build it into citrus, woody, or spiced compositions where it works as the quiet backbone holding everything together.
