neroli

Neroli is named after Anne Marie Orsini, Princess of Nerola — a small town in Lazio, central Italy — who in the late seventeenth century is said to have popularized the use of bitter orange blossom oil as a personal fragrance, particularly for scenting gloves and bath water. The attribution follows the common European pattern of naming ingredients after the aristocratic patrons who made them fashionable, though the oil itself long predated the princess: bitter orange blossom had been distilled in the Arab world for centuries under the name zahrat al-laymun (orange flower). What the princess gave it was not the smell, but the commercial name that stuck.

The bitter orange tree, Citrus aurantium, produces three entirely distinct raw materials for perfumery from different parts of the same plant: neroli from the flowers (steam-distilled), petitgrain from the leaves and twigs (steam-distilled), and bergamot from the rind of a related citrus (cold-pressed). Neroli is the most expensive of the three by volume — it takes roughly a thousand kilograms of blossoms to produce a single kilogram of oil, and the blossoms must be picked by hand before sunrise to catch the peak aromatic compound concentration. Tunisia and Morocco now supply the majority of the global neroli oil market.

Neroli's scent is at once floral and fresh, honeyed and green, with a characteristic waxy, indolic undertone — indole being a compound present in many white flowers that, in isolation, carries a faintly animalic, fecal edge, but in the context of the full flower reads as richness and depth. In classical French perfumery, neroli was one of the foundational materials in the cologne and eau de cologne tradition — the original Eau de Cologne formulated in Cologne, Germany in the early eighteenth century contained neroli as a central note. The modern use of neroli extends from high-end perfumery to naturals-based aromatherapy to the flavoring of pastries in Mediterranean cuisines.

Orange blossom water — the byproduct of neroli distillation, the hydrosol that remains after the oil is separated — has its own parallel history in cuisine and cosmetics. In Moroccan, Tunisian, Lebanese, and Turkish cooking, it flavors pastries, milk puddings, and beverages. In North African personal care, it is used as a toner and hair treatment. The same distillation process that yields neroli oil for Parisian perfumers yields orange blossom water for Fez pastry kitchens; the two products have traveled in opposite directions geographically while sharing a botanical origin.
