RoastNote 235

RoastNote 235 is a high-impact roasted material that captures the dark warmth of toasted nuts, cocoa powder and browned crust.

Its compact profile can transform a smooth gourmand accord by introducing the slight dryness and aromatic tension that make a roasted effect feel convincing.

Beyond sweetness, it brings shadow and texture.

A trace can suggest cocoa husk, roasted grain or hazelnut skin, while a more deliberate treatment can create an assertive coffee, praline or toasted-wood signature.

Its particular luxury comes from contrast.

RoastNote 235 can set burnished, almost blackened detail against cream, vanilla or fruit, giving a composition the complexity of something caramelised, roasted and still warm rather than simply sweet.

Odour profile

The odour is intensely nutty and roasted, with cocoa-like, earthy and baked-potato nuances.

A dry, slightly powdery character gives the material depth, suggesting nut skins and the browned edge of a roasted accord rather than simple sugary sweetness.

At first encounter, the effect is concentrated and savoury, recalling freshly roasted kernels, dark crust and the dry shell of a hazelnut.

The impression is powerful, dry and immediately textural.

In careful dilution, more nuanced facets become visible: toasted hazelnut, cocoa powder, warm grain and a faint earthy smokiness.

These details make the material useful as a source of realism and depth rather than sweetness in its own right.

Using RoastNote 235 in perfumery

RoastNote 235 is useful in coffee, cocoa, nut, praline, tobacco and baked-gourmand accords.

It can also add a charred, savoury accent to leather, patchouli, smoky woods and dark amber constructions when used with particular restraint.

Within gourmand perfumery, it can turn a smooth vanilla or caramel accord into something more faceted, adding browned edges to praline, biscuit, coffee and cocoa themes.

It can also make nut effects feel less creamy and more freshly roasted.

Outside the gourmand palette, traces can introduce a charred shadow to tobacco, leather, patchouli and dark woods.

The material is most expressive when it appears as a precise detail, revealing itself gradually rather than dominating the fragrance.

Creative pairings

Explore RoastNote 235 with coffee materials, cocoa, hazelnut, maltol, vanillin, tonka effects, tobacco, patchouli, cedarwood, guaiacwood, labdanum and leather notes.

Careful dosing preserves its luxurious toasted detail and avoids overwhelming quieter materials.

Set it against milky, creamy or vanillic materials for dramatic contrast, or deepen its darker character with vetiver, guaiacwood, patchouli, labdanum and suede effects.

Fruity accents such as cherry or plum can create an especially decadent roasted-gourmand tension.
