The raw materials, and what they do.

A cold, slightly bitter citrus pressed from the rind of a small Calabrian fruit. It opens almost every fragrance we make — bright, immediate, and gone within the hour.

Not a true pepper but a rose-family berry. It adds a dry, faceted sparkle to the top of a composition without the heat of black pepper.

A mineral accord rather than a single material — the smell of air near cold water. We build ours with real texture instead of the confected ozonic notes most aquatics rely on.

Powdery, cool and expensive to source — the butter is aged for years before use. Unmistakable once you've smelled it, and the quiet centre of both Petrichor and Brume.

We use a dark, slightly jammy rose absolute, dosed low. It keeps a smoky heart from reading as purely austere without ever tipping into sweetness.

Distilled from bitter-orange blossom — waxen, honeyed and green all at once. It hands the top notes over to the heart in Solaire without a seam.

A grass root that smells of smoke and wet earth. We grow ours in the wrong soil on purpose, for a darker cut than the citrus-forward vetivers most houses reach for.

Resinous heartwood, used in a clean, low dosage rather than the barnyard cuts that exhaust the nose. In Cendre it reads as depth, never as a statement.

We use a synthetic-free substitute built from ambroxan and labdanum — warm, skin-like, and faintly marine. It is the last degree of warmth in Brume and the anchor beneath Solaire.
