Even if you are smelling a perfume called “jasmine,” you are not really smelling just jasmine as the aroma of the flower exists in the real world. It is always someones interpretation of what jasmine smells like. First off there are many types of jasmine used in perfumes. There are headspace reconstitutions that chemically map out the aroma of jasmine in bloom at a particular/place and time and are recreated in a lab with the same basic chemical make up of the flower’s aroma. But it must be put into a setting that lasts on the skin and must be adjusted by someone who has trained their nose to recreate an aroma from tiny bottles of raw materials. Perfumes named after plants or flowers are cover songs.
