This is seriously lovely. It's not branded but came from the duty free in Port-au-Prince airport, the only place I was able to track down vetiver oil in haiti, with a hand-written label.
The colour is hard to discern as the plastic bottle is blue and quite tough, so it's difficult to squeeze out more than a drop of oil at a time. But I think it's much more brown than the indian khus, while still having a greeny tinge.
The opening is powerfully earthy, medicinal and iodinic, with very little sweetness. After about 30 minutes the warmth and sweetness start to kick in. It's warm, a bit grassy, with a not overpowering biscuity sweetness sparked up by an almost effervescent shimmer. There are shades of flint - almost frankincence-like. The deep dry down is nothing short of etherial, a swirl of contrasts and very hard to place properties, with sweet and dry, green and brown, warm and cool, earthy and airy.
This is very complex and multi-phased in its progression on skin - moreso than many perfumes. I would wear it on its own and my holy grail is to find a perfume which faithfully exhibits both the opening and the dry down of haitian vetiver oil with a bit more projection and longevity.
Edit: now I'm comparing this Haitian and Trebor's Bourbon vetivers simultaneously. They're actually very similar, the bourbon being a little more smooth and, for me, the Haitian having perhaps a little more complexity, but also a slightly harsher furniture-polish facet which the Bourbon lacks.
