I also fell in love with the Blaise Mautin fragrance at the PH Vendome when it came out many years ago. A recent article in AmEx's Departures magazine gives quite a bit of detail on the olfactory composition of the scent:

... built on woody, minty patchouli, in homage to the hotel's rich mahogany details ...
... To soften the patchouli ("It can be a bit stiff," Mautin admits), he used an extract of sweet Brazilian oranges from the famed French Scentaromatique in Grasse. He put in a natural sandalwood as well as a synthetic molecule trade named sandalor ... Mautin also added ethyl vanillin and absolue de vanille (the first is synthetic and the second natural) to impart a subtle powdery amber element and softness, along with a leathery-scented base from Russia that he compares to the comforting scent of burning wood. The finished formula, which only Mautin knows, contains more than 18 materials.
