Description and usage notes:

This is an extremely useful green note, having the effect of freshly crushed stems: traces can give a freshening, lifting effect; larger amounts (0.5 – 1%) will give a distinctive green note that may become metalic depending on what it’s blended with.

Description from Givaudan: “Green, Natural, Leafy, Fresh, Powerful. Imparts a natural and fresh nuance to fragrance notes such as lily-of-the-valley, narcissus, mandarin, fig leaves, grapefruit, black currant and tomato. It is an excellent modifier that strengthens and modernises green notes.”

Arcadi Boix Camps describes the scent of this material as “somewhere between galbanum and fig leaves absolute”

Jean Claude Elena, in his book Diary of a Nose, suggests that in combination with gamma-Octalactone this material can produce an effective illusion of the smell of figs.  He says “Stemone gives an impression of mint leaves or fig leaves, it all depends on what I want to make it say.  For the smell of ripe figs I recommend adding ethyl maltol, but for dried figs the answer lies in concrete of iris.”

We suggest you might want to save some money and substitute Orris Givco for the expensive concrete of iris however.  Also keep in mind that while this combination does give a terrific illusion of figs, gamma-Octolactone,  ethyl maltol and even orris are much longer lasting than Stemone, so the illusion tends to break into sweet coconut over time.
