It's a interesting question to be sure. I don't think that science is going to drop what they are doing to indulge all our questions about the finer points of fragrance either, but maybe there is an intrepid chemist of good taste that is out there! I can only speak from my conversations of those in the industry and my own personal experience. Different compounds react to different things, so it's pretty complex and super difficult to pin down hard and fast cause and effect. Just as a good fragrance has a very nuanced nose, it has very nuanced properties!couch wrote:Ha! Indeed they were.gegarrenton wrote:Those bottles were corked though, correct?.
So this raises the question of how much the changes in the aromatic compounds in scent depend on aerobic/oxidative reactions and how much on anaerobic ones or on light or heat. And how much the exposed surface area of liquid in a closed bottle (tester or splash) is actually affected by the contact with air over time. Naturally the agitation of splashing will expose new surface to the air; how much difference does that make?
I'm all ears.
I'm not telling anyone not to give the old fragrance a shot, but I personally couldn't recommend it. I'll happily send along a decanted bit of old Guerlain to anyone who wants to do some A/B testing on their own.
