Sorry it's taken me so long to reply to your message - I usually don't log-in when I visit Basenotes, so the whole message thing escapes me.
Anyhoo, I am not sure about the provenance of the JH EDP that you describe. I (coincidentally) just got a new bottle of the EDP for Xmas, and I have literally just had a good squirt to see if I can detect the "metallic" note in mine that you all smelled in your bottle. I can't. All I can smell is the spices. I suggest you could have a spray at Sephora then go home and compare!
I just got a bottle of Jaipur Homme EDP in the mail today - a purchase from a fellow BN member. I've worn both the EDP and EDT before and know what they should smell like. This bottle has a faint but sharp metallic smell in the opening and hardly any of the spicy top notes that I love in JH. I have had a cold lately and thought that maybe it was just my nose (I've had a cold), so I let my wife and daughter smell it and they detected the metallic smell as well. The metallic smell fades away after about 10 minutes and you get the normal sweet powdery drydown. What does Jaipur Homme smell like once it starts to go bad? Have you ever experienced this? Do you think I got an old bottle? Thanks.
