I read what Turin said as well, but the decant I got, and then the partial bottle (in the square export bottle) both smelled really good. Folks don't seem to agree on how to decipher Lutens batch codes, so I can't tell you how old my bottle is, and all I can really say is that there still is some good stuff out there if you can manage to locate it.
Export bottles on E-bay probably all date back to the time when it was being exported to North America, but I can't tell you how long ago that was. Several years ago though.
Count me among those who believe that almost all newly marketed versions of older frags have been reformulated to conform to IFRA regulations. I suppose there are some fragrances which never contained any of the restricted materials (could that be true ?) and so remain the same as always, but I suspect that most frags were in violation to one degree or another.
