If you take the lid off of the bottle for a night or two, it may help, which is what those above refer to as steeping.
There's nothing worse than a juice that tastes like perfume. Some of them get much better with steeping. Some are just awful forever.
I wish I could tell you what the chemical is that causes it, but I'm not a chemist, nor do I have access to the equipment to test it. It sure doesn't seem like a good thing, though.
I always steep juices like that for a week or so, and if it still smells like that after, I toss it out.
