I live in the Sultanate of Oman,
And have been to Amouage factory a lot,
Not a single scent is made here,
All of them come from Grasse and other places and then diluted
And packaged here.
However the vision and inspiration behind every scent is collaborative between the creative director, Christofer Chong and the Omani directors.
As for OP, my experience with all Middle Eastern scents which are made in French and Western style is that they are linear and superficial.
But when it comes to the Oud and the real middle eastern essence, nothing comes close,
And that is primarily because IFRA rules do not apply here, so companies here use the real thing!
To name a few:
The house of Arabian Oud, they have a couple of oriental scents like Somou (sadly discontinued) and Woody. Never smelled anything from a Western offering like them.
ASAQ: they have Dehn Oud Ateeq; I can not describe it until you try it for yourselves.
Personally I like the niche houses which are in the middle like: Serge Lutens, Mondale, Guerlain...
Is the new factory complex in Oman not functional, Salim?
I have some 'attars' that were mixed there a while back, although they were bought privately.
I do agree that people should think of exploring A.S.A.Q., Ajmal and others, although I feel that they may be best sourced outside Europe.
