Vetiver is one of perfumery’s great base notes: deep, earthy, smoky and endlessly useful. In India it has been loved for centuries as khus, cooling summer homes and scenting attars. Here is what makes the oil so valued, and what to look for when you buy it.
What is vetiver oil?
Vetiver oil is an essential oil distilled from the roots of vetiver grass (Chrysopogon zizanioides), known in India as khus. It is thick, amber to dark brown, and smells earthy, woody and smoky. It is one of the most important base notes and fixatives in perfumery.
Vetiver is a tall, clumping grass native to India, grown today across the tropics. Its dense roots, which hold the oil, can reach deep into the soil, and the plant is also widely used to prevent soil erosion.
What vetiver smells like
Vetiver is earthy and rooty, with woody, smoky and sometimes nutty or grapefruit-like facets. Depending on origin it can be cleaner and more refined, or darker and more smoky. It is calming, grounding and very long-lasting.
How vetiver oil is made
- Harvest: the roots are dug up, typically after the plant is 18–24 months old.
- Cleaning and drying: roots are washed, dried and often chopped.
- Soaking: roots are soaked to help release the oil.
- Distillation: long steam or hydro distillation runs, because the heavy molecules release slowly.
- Ageing: like many base notes, vetiver softens and improves with age.
Vetiver can also be CO₂ extracted, which captures a fuller, rootier profile, and fractionated to produce cleaner grades and isolates.
Origins and grades
| Origin | Typical character |
|---|---|
| India (khus) | Deep, earthy and rich. Wild North Indian “ruh khus” is especially prized and rare |
| Haiti | Clean, refined and slightly sweet. A benchmark for fine fragrance |
| Java (Indonesia) | Darker, smokier and heavier |
| Réunion (“Bourbon”) | Historically celebrated, now produced in small volumes |
Grading: beyond origin, vetiver is graded by colour, odour profile and composition. Fractionated or “clear” grades remove some of the heaviest, smokiest notes for lighter applications.
How vetiver is used
- Fine fragrance: a base note and fixative in woody, fresh and chypre perfumes, especially men’s and unisex scents.
- Attars: khus attar is a classic cooling summer attar, and vetiver is a key part of shamama.
- Home fragrance: in candles, diffusers and incense for a calm, grounded note.
- Personal care: in soaps, body oils and grooming products.
- Traditional use in India: khus mats (khus tatti) cooled and scented homes in summer, and khus is a familiar flavour in sherbets.

Buying vetiver oil in bulk
- Ask for the origin and grade, and smell a sample of the specific lot.
- Request a COA and GC-MS report to confirm composition and purity.
- Check for adulteration. Vetiver is sometimes extended with cheaper oils or synthetics.
- Look for supply security. Suppliers who cultivate or process their own vetiver can offer more consistent quality.
