I recently purchased a bottle of Oud Extraordinaire from Ensar Oud and was blown away by the sample bottle of Satori Fusho (SF) that came with it. It was completely different from the Oud Extraordinaire in that it was extremely floral and rich with absolutely no smokiness. I decided to purchase a bottle of Satori Fusho hoping for the same qualities in the sample, however, I noticed some significant differences between the sample (S) and full bottle (FB). 1. FB is darker than S. 2. FB is less viscous than S. 3. The floral character of FB is hidden under a "smoky" note (I have smelled this in other ouds and it is a prominent note in eaglewood oil), which disappears when exposed to air revealing it's smooth character. I am hoping the differences are only related to duration of exposure to air since the sample bottle seem less secure than full bottle. To experiment I put some of full bottle FB (diluted with etoh) into a micro centrifuge tube (MCT) and have it sitting side by side with the sample S and it is definitely darker. Since these centrifuge tubes have a bad seal a little oxidation can occur and the etoh will eventually evaporate. Note: I can tell from smelling the cap of the MCT that the FB smells almost identical to S albeit a little weaker. Does anyone else have experience with this phenomenon?
