How to Build a Gourmand Accord: Vanilla-Caramel Formula and Ratios

A gourmand accord is perfumery's gateway to the kitchen. Vanilla, caramel, sugar, cream — the flavours we know from the plate, written into the air. As a fragrance family, it falls under the gourmand category and is typically used in the mid-to-base layer to build a warm foundation.

Why isn't a single raw material enough? Because there is no pure molecule sold simply as "caramel." The caramel illusion is a collective hallucination produced together by the sharpness of burnt sugar, the softness of vanilla, a nutty creaminess, and a faintly resinous depth. An accord is the name given to the family of molecules that constructs this illusion.

Once you learn to build a gourmand accord, you'll also see how it converses with floral accords. A rose or jasmine sitting atop a sweet base takes on an entirely different character. Here, we're building the sugar illusion from scratch.

The table below lists the accord's key components along with their CAS numbers and suggested starting ratios. You must weigh and test these ratios on your own scale — the potency of each raw material varies by brand.

Treat the values in the table as a starting point. The real work is weighing them on paper blotter strips (mouillettes) and finding the balance with your own nose.

The accord's power comes from every molecule being in exactly the right role. Let's look at them one by one.

Ethyl Maltol is the heart of this accord. It carries the recognisable sweetness of cooked sugar, candy floss, and caramel. It is extremely potent — a little goes a long way. This is the molecule that constructs the accord's "sugar illusion."

Maltol is the warmer, more "bakery" side of Ethyl Maltol. It contributes a burnt-sugar and bready nuance. Using both together adds depth to the caramel; on its own, Ethyl Maltol can stay too "confectionery" — Maltol pulls it towards a baked quality.

Vanilin is the classic vanilla pillar: sweet, spicy, powdery. Ethyl Vanillin is its sibling — roughly three times more powerful, rounder, and creamier. Dosing both together makes the vanilla note simultaneously clear and voluminous.

gamma-Nonalactone (also known as aldehyde C-18) brings a creamy, coconut-and-peach softness. It blurs the sharp edges of caramel into an oily cream; this is what gives the gourmand accord its "melts in the mouth" sensation.

Furaneol contributes a note of caramelised sugar, strawberry jam, and candied fruit. At very low doses it adds "realism" to the accord; too much weighs it down like jam. Use it with care.

Benzoin Resinoid lays a balsamic, resinous base. It grounds the sweetness, supports the vanilla, and simultaneously acts as a natural volatility regulator, slowing the accord's early diffusion.

Coumarin builds a bridge of dry hay, almond, and sweet tobacco. It binds the vanilla and caramel together, adding that familiar "tonka" warmth to the gourmand accord.

Galaxolide and Cetalox are the accord's blenders. Galaxolide spreads a clean, powdery musk halo, gathering all the sweet notes into a single cloud. Cetalox adds an amber-mineral depth and sillage, anchoring the accord to the skin.

Rather than blending the accord all at once, build it layer by layer. When the top note has evaporated, the base layer takes the stage — establish the balance from the outset.

Once the accord is complete, allow it to rest for maceration (alcohol-fragrance oil maturation). Maceration is a chemical ageing process that slows as temperature drops; for this reason it should be kept at room temperature (~15–20 °C) and in the dark. Refrigeration slows maceration — it does not speed it up. Two to four weeks is a typical timeframe; wait for the accord to "settle."

After maceration comes a separate step: chilling (~0–4 °C, ~24 hours). The purpose is to precipitate any waxy materials that have not fully dissolved. These are then removed by cold filtration. Do not confuse the two steps: first mature at room temperature, then chill and filter.

Once you've built the core accord, you can steer it in your own direction. Below you'll find both creative variations and the safety framework.

Is natural or synthetic safer? This question is poorly framed. Safety depends not on the source but on the molecule and the level of use. Coumarin occurs in high concentrations in natural tonka bean and is an IFRA-restricted allergen; by contrast, purely synthetic Galaxolide and Cetalox are considered very low-risk from an allergy standpoint. Saying "natural = safe" is both incorrect and a legal liability.

IFRA limits are set not against the total fragrance oil concentration but against individual ingredients within the fragrance oil and the product category (leave-on/rinse-off). In this accord, several components — most notably Coumarin and Vanilin — are restricted. Do not proceed to production without verifying current IFRA limits and the compliance declaration for your intended category.

When working with solvents and high-proof alcohol, be aware that these materials are flammable (low flash point). Good ventilation, avoidance of static, and appropriate protective equipment (gloves/goggles) are essential.
