"The bourbon quality (10% of total production) possesses an additional rosy tonality with sulfury aspects, while vetiver oil from Haiti (50% of total production) shows additional aspects reminiscent of jute and roasted peanuts, and the Java and China qualities (together 35% of total production) have harsh and smoky bynotes. All vetiver oils share, however, a characteristic and distinctive suave and sweet woody-earthy odor with green, grapefruit- and rhubarb-type facets that is much appreciated in perfumery." \\ | "The bourbon quality (10% of total production) possesses an additional rosy tonality with sulfury aspects, while vetiver oil from Haiti (50% of total production) shows additional aspects reminiscent of jute and roasted peanuts, and the Java and China qualities (together 35% of total production) have harsh and smoky bynotes.
