Not applicable — distilled spirit. References: Zea mays (corn ≥51% mash by law), Hordeum vulgare (barley), Secale cereale (rye) or Triticum aestivum (wheat), distilled to ≤80% ABV, aged in new charred American white oak (Quercus alba) barrels.

Producing Countries
Not applicable to the accord. American bourbon is legally restricted to US production; Kentucky produces ~95% of the world's bourbon (Buffalo Trace, Heaven Hill, Brown-Forman, Wild Turkey, Maker's Mark, etc.). Other US states with bourbon production: Tennessee (Jack Daniel's, technically Tennessee whiskey), Indiana, Texas.
Pyramid
Heart–Base
A reconstructed gourmand-woody-spirituous accord — vanilla, caramel, charred oak, with a soft corn-grain sweetness underneath. American bourbon is legally defined: ≥51% corn mash, distilled in the United States, aged in new charred American white oak. The fragrance accord turns on the whiskey lactones extracted from that charred wood.

The oak heart emerges: whiskey lactones forward (coconut-creamy-oak), vanillin and guaiacol providing depth, the corn sweetness underneath.

A quiet woody-vanilla base; the charred oak character persists as a soft smoke-and-cream memory.
The Full Story
Bourbon whiskey is the United States' national spirit, legally defined since 1964 as American-distilled grain whiskey from a mash bill of at least 51% corn, distilled to no more than 80% ABV, and aged in new charred American white oak (Quercus alba) barrels. The 'bourbon' name traces to Bourbon County, Kentucky — the eighteenth-century region where the style emerged from German, Scottish and Scotch-Irish distilling traditions transplanted to American grain crops.
The whiskey lactones
Bourbon's aromatic signature is dominated by compounds extracted from the charred oak during ageing — and most distinctively by the so-called whiskey lactones: cis- and trans-β-methyl-γ-octalactone (CAS 39638-67-0 / 39212-23-2) [A]. These compounds exist in oak heartwood as glucoside precursors and are released during charring and ageing. Crucially, American white oak (Q. alba) carries roughly three times more lactone precursor than European Q. robur or Q. petraea — the chemistry that distinguishes bourbon's coconut-creamy-vanilla character from cognac's softer-spicier French-oak profile.
Other oak contributors
Vanillin (CAS 121-33-5) is also extracted from oak heartwood — it is the same compound that defines real vanilla, present here as an oak-lignin breakdown product during charring. Guaiacol (CAS 90-05-1) supplies the smoky-phenolic angle. Furfural (CAS 98-01-1) adds sweet-almond charred-sugar warmth. Around this oak-derived skeleton sit the fermentation-derived ethyl esters (ethyl hexanoate, ethyl octanoate) that give bourbon its fruity-spirituous top.
In perfumery
Bourbon is a Fantasy/Concept reconstruction in fragrance — no actual whiskey is used in perfumery (the ethanol would dominate; the perfumery accord is built from the aromatic compounds, not the spirit). The accord pairs naturally with vanilla, tonka, tobacco, leather, dark woods and dried fruits. Niche-perfumery examples invoking bourbon explicitly are uncommon but increasing in the gourmand-woody category since around 2015.

Did You Know?
Did you know?
The 'whiskey lactones' — cis- and trans-β-methyl-γ-octalactone — are not produced by fermentation but are extracted from oak heartwood during barrel ageing. Quercus alba (American white oak) carries roughly three times more lactone precursor than European Quercus robur or Quercus petraea, which is why American bourbon develops the characteristic coconut-vanilla-oak signature that French oak (used for cognac and wine) does not. The compounds are present in oak's heartwood as glucosides and hydrolyse into the volatile lactones during the charring and ageing process. They are the chemical fingerprint that distinguishes bourbon from Scotch (aged in used barrels) and cognac (French oak).
Extraction & Chemistry
Extraction method: Not applicable. Bourbon is distilled and aged, not extracted as a perfumery material. Real bourbon contains ethanol at 40–50% ABV, which is the principal volatile carrier; the aromatic signature comes from compounds leached during oak ageing (vanillin, lactones, guaiacol, furfural) plus fermentation esters. In perfumery, the bourbon accord is reconstructed from synthetic blocks evoking the oak-aged spirit.
Not a single material. Bourbon's aromatic signature comes principally from compounds extracted from charred Quercus alba barrels: vanillin (CAS 121-33-5); cis- and trans-β-methyl-γ-octalactone (the 'whiskey lactones', CAS 39638-67-0 / 39212-23-2); guaiacol (CAS 90-05-1); furfural (CAS 98-01-1). Plus ethanol-fruity esters from fermentation: ethyl hexanoate (CAS 123-66-0), ethyl octanoate (CAS 106-32-1).
Botanical Name
Not applicable — distilled spirit. References: Zea mays (corn ≥51% mash by law), Hordeum vulgare (barley), Secale cereale (rye) or Triticum aestivum (wheat), distilled to ≤80% ABV, aged in new charred American white oak (Quercus alba) barrels.
IFRA Status
Not applicable — reconstructed accord. Constituent compounds carry their own profiles: vanillin unrestricted; whiskey lactones unrestricted at perfumery levels; guaiacol carries IFRA 51st Amendment category limits as a phenolic at higher concentrations.
Bourbon whiskey is a Fantasy/Concept gourmand-spirituous accord, not a perfumery raw material. It sits in the heart-to-base of gourmand-woody compositions where a spirit-aged-in-oak reference is wanted. It pairs naturally with vanilla, tonka bean, tobacco, leather, dark woods (sandalwood, cedarwood), and dried fruits. Not used in any current Première Peau composition; the closest gourmand register in the PP line is the saffron-praline-warmth of Insuline Safrine.
