ABOUT COUMARIN

Coumarins are polyphenolic compounds belonging a group of colorless and crystalline oxygenated heterocyclic compounds first isolated from the plant named Dipteryx odorata Willd. [1] Coumarin is a colorless crystalline solid with a sweet odor resembling the scent of vanilla and a bitter taste with grassy elements.

Nowadays, coumarin is usually derived from the tonka bean but is also found in other plants, including lavender, sweetgrass, and sweet clover. Coumarin is commonly synthesized artificially for its use in perfumery. 

From The big book of Perfume:

In 1856, this hay- and tobacco-scented molecule was discovered by Friedrich Woohler and Justus von Liebig in tonka beans. William H.Perkin first synthesisted it in 1868.

Coumarin brings me to my childhood baby crib

I don’t know why when I tried to imagine some images associated with this note, the picture of a bamboo or wooden baby crib appeared in my mind.
It reminds me of a time when I was young and still a baby trying to stand stably in the baby crib. I could not remember the musky scent of coumarin when I was a kid, but I could not forget the link between them with my younger bro’s crib.

My own olfactive experience:

First try: it’s kinda bold, earthy, mossy and plastic. Coumarin is a vanilla-like odor with the green nuance.

For 2 hours: Its scent is more charming with the warm and sweet facets, little tobacco, earthy, woody.
