Hi Butterscotching! Welcome to Basenotes!
Néroli still appears on the Annick Goutal website...is it possible that it isn't discontinued at all, but merely no longer being carried by the store where you shop?
In any case you can settle the question by asking their customer service at this email address: (they are very responsive)
