Acqua Nobile is a citrus/floral mix that leans probably more to the floral side imo. Upon the initial spray I get an overall sense of cardamom, neroli and orange blossom. This hangs around for awhile until it becomes a sort of powdery/neroli mix. This is the heart of the fragrance to me - a kind of soft, linear neroli/powdery type of fragrance. AN also has good longevity, probably close to nine hours or so on me.
AN is one of those scents that I like, but I'm not sure if I like it enough to actually purchase it. Normally my own method is to go find a price for it and see if I think the smell is worth the price. In this case I have to say "no," but that's not to say other people might not like it.
