The answer? Both, neither and a combination there of. The note pyramids are chiefly a marketing device and can bear zero resemblance to the fragrance they purportedly describe or its ingredients; you might suffer some customer backlash, angry emails about how their is no discernible "Sea Scent" in Millesime Imperial middle section, but you wouldn't be breaking any laws or regulations. Even if we had the formulas for these perfumes to compare with the descriptions we couldn't determine much because, even if the Tabarome contains no real Tobacco accord, the other ingredients might create the effect in combination.
Here's an example! One website lists Tabac Blond as follows:"Top Notes:leather, carnation, lime Middle Notes:iris, vetiver, ylang-ylang, Base Notes:cedar, patchouli, vanilla, ambergris, musk."
And here's a formula for Tabac Blond (reposted from david in this thread http://www.basenotes.net/threads/192...s-!!!?p=969508 many thanks david):
114 Benzoe Siam
59 Resinoid Olibanum
23,5 Amberoil (rectified)
59 Moschus Keton
23,5 Rose Absolue
59 Phenylethylphenylacetat So.
35 Petitgrain Gr
14,5 Ambrette seed oil
Please note I have no idea how accurate this is or which formulation but it's interesting to see what might be readily identified and what is an illusion =)
