I think that Ananas Fizz is supposed to be a pineapple perfume.
Many perfumes use bergamot as a top note, and I can tell you that, by itself, the real, natural substance smells halfway between lemon and orange. However, bergamot is a short-lived note. There has to be some other fruit that you are smelling and enjoying in the L'Artisan fragrance.
After looking in the reviews, I quote Basenotes member Vibert here: "Maitre Parfumeur et Gantier have explored the same territory more successfully with their recent Bahiana, which has all of the depth, complexity, and lasting power lacking in Ananas Fizz, while remaining just as bright and effervescent."
