Jasmine

Jasmine absolute is among the most precious materials in the perfumer's organ, and its production demands a level of patience and precision that few other botanicals require. Jasminum grandiflorum, the species most valued in perfumery, blooms only at night — the small, star-shaped white flowers begin opening at dusk and reach peak oil concentration in the hours before dawn. Pickers must harvest the blossoms by hand during this narrow window, working through the darkness with headlamps or by the light of the moon. A skilled picker can gather roughly half a kilogram of flowers per hour, and approximately 8,000 flowers — weighing about one kilogram — are needed to produce just 2 to 3 grams of absolute.

Unlike rose, jasmine cannot be steam distilled without destroying its delicate aromatic profile. Instead, the flowers undergo solvent extraction: a hydrocarbon solvent washes through the petals, dissolving the fragrant compounds into a waxy substance called a concrete. This concrete is then washed with ethanol to separate the wax from the aromatic molecules, yielding jasmine absolute — a deep reddish-brown liquid of extraordinary richness. In Grasse, where jasmine has been cultivated since the sixteenth century, a few remaining farms still produce limited quantities of this absolute, though the majority of the world's jasmine now comes from Egypt's Nile Delta and the fields around Madurai in southern India, where lower labor costs make large-scale production viable.
