But I do think citrus notes may go off sooner than others. I recall reading that the Osmothèque recommends a cooler storage temperature for citrus than for non-citrus perfumes.
Also, a year and a half ago when I was first considering buying L'Artisan Fleur d'Oranger 2007 and tested it/obtained a decanted sample from a store in CT that had kept a tester on display, I found the the top notes were damaged, compared with samples I bought from L'Artisan and Beautycafe. (And if you think about it, this was created in 2007, so it wasn't even so very old.) I almost didn't buy the fragrance at all based on that sample. Fortunately I retested with other samples, or I would never have known what it really smelled like.
So I think the big question is, was it kept out of the light?
