I had the same problem out of SMW my friend and there is nothing you can do about it but get rid of it. Mine also had the dominate pepper (black currant) note that was strong and smelled like it had went bad. I knew it wasn't supposed to smell like this as I had samples. I got it from a store that may not have been ligit and sadly payed full price for it. Well, I ordered a real bottle from Neiman Marcus and much to my pleasure, it is wonderful and everything it should be!
Cold climates may slow chemical reactions but they will not repair anything.
