There is no plum oil. Press the fruit and you get juice; nothing a perfumer can bottle survives the attempt. Wikiparfum, the industry's online fragrance encyclopedia, is blunt about it: the velvety plum note does not come from the fruit at all.
It is rebuilt in the lab from a family of molecules called damascones. They sit in the same molecular family found in rose notes, which is why a good plum accord glows slightly floral under the fruit. The strongest of them register at tiny doses, so a perfumer needs only a whisper to put ripe fruit into a formula. On skin the effect is deep and sweet, with what Wikiparfum calls "a curious liqueur nuance". Think jam, mulled wine and dried fruit rather than fresh orchard.
That tells you how to read a note pyramid. Plum signals darkness and weight. Perfumers reach for it when they want fruit that behaves like an oriental material. It sinks into amber, tobacco and woods instead of floating on top the way citrus does. It is the difference between a scent that smells of fruit salad and one that smells of velvet.
One thing to be clear about: most fruit notes on a modern pyramid work exactly the same way. Peach, cherry, apple, all rebuilt from molecules. The £300 niche bottle and the £40 one draw from the same catalogue of materials, because there is no alternative. Nobody can farm a plum grove for oil. What separates the bottles is the blending, not some secret orchard.
Our own plum sits right at the top of Nuit Parisienne (our take on Night in Paris by Maison Asrar), which opens beside black cherry and raspberry over a musk, amber and vanilla base, in a UK-made 35% extrait. See the rest of the Maison Asrar collection.
