Field notes / 01
What does bitter orange smell like?
Bitter orange combines juicy freshness with a firmer rind-like edge than sweet orange. The impression can be green, tart and lightly spicy, which makes it a useful antidote to heavy sweetness. Think aromatic peel rather than marmalade, unless gourmand notes deliberately push the composition in that direction.

The material behind the impression
The bitter orange tree, Citrus aurantium, supplies several different perfume materials. Peel oil is not the same as neroli from distilled blossoms, orange blossom absolute, or petitgrain from leaves and twigs. A note list can describe a recreated bitter-orange effect without confirming the use of natural peel oil.

Its place in the composition
Bitter orange gives tropical fruit a sharper outline and connects easily to flowers or resins. In a vanilla-rich composition, it can make the opening feel fresher without changing the warmth of the base. Its contrast with sweeter materials is often more important than how long the literal citrus impression remains.
