I bought a new 100 ml bottle too, but I had an older sample, and I did notice a small difference too. Yet, I wasn't sure if it was really a bad change... I did get some Route du Vetiver, but I got the older 90 ml bottle and it matched my sample. But you're right, I wish they wouldn't mess with it. Particularly I spend a good bit of $$'s on samples, and then when you actually do find something that is bottle worthy ( I have to smile in remembrance of "Seinfeld" Spongeworthiness!) they go and change the thing. I'm waiting for a bottle of Iris Bleu Gris now, and I definitely hope it smells like my sample!
