I also love Vanilla absolute and I use it in very small amounts because of its price. I agree, it is such beautiful and complete smell but it dosen’t last too long. There’s many complex aspects to vanilla abs. (dark, phenolic, spicy/sweet) so I’m not claiming I can reproduce it accurately, but I use things to extend the note. Benzoin Siam, Phenylacetic acid, Clovebud absolute, Veratraldehyde, Ultravanil (Givaudan)
