It feels substantial on the skin, ending with a deep dry down of myrrh and sandalwood. It is ideal for autumn and winter evenings, offering a rich, multifaceted sweetness that leans sophisticated rather than youthful.

A thick, syrupy blend of cognac and hazelnut that settles into a creamy praline heart. The texture is dense and resinous, anchored by cinnamon, tonka bean, and a balsamic base of myrrh. It smells like a sophisticated dessert served in a library with old oak shelves.
Main Accords
10 MAPPEDThe sweet and warm spicy accords dominate the wear, but they behave in a heavy, opaque way. The boozy cognac is sharp early on, while the ambergris provides a salty structural support that prevents the vanilla and sugar from becoming cloying in the cold.

EDITORIAL“Substance by Synesthesie: A Boozy Hazelnut Powerhouse for Winter”
Substance opens with an assertive splash of cognac that feels expensive and spirited. This is not the scent of a sticky floor but rather a fine, aged spirit in a crystal glass. The hazelnut note appears almost immediately, providing a toasted, dry texture that cuts through the initial booziness. It creates an immediate impression of warmth and luxury that feels well suited for a formal evening or a quiet night by a fire.
As the spirit notes begin to settle, the heart reveals a spicy core of cinnamon and tonka bean. There is a perceptible graininess from the cane sugar, but it is kept in check by a surprising inclusion of oakmoss. This earthy element prevents the fragrance from sliding into pure confectionery territory. The cinnamon is warm and dusty rather than sharp, blending seamlessly with the almond-like facets of the tonka.
The dry down is where Substance really lives up to its name. A thick praline note emerges, supported by a rich, non-synthetic vanilla. Myrrh adds a balsamic, slightly smoky depth that keeps the sweetness sophisticated. It lingers on the skin with a resinous quality, while sandalwood provides a smooth, creamy foundation that lasts for many hours. The white musk in the base is clean but carries the weight of the heavier resins.
On the skin, the accords move from sharp and alcoholic to soft and resinous. The sweetness is persistent but changes shape, moving from the crystalline sugar in the heart to the buttery praline in the base. The ambergris provides a subtle salty flicker that appears occasionally, adding a necessary contrast to the dominant warm spices. It feels dense and opaque, like a heavy wool coat for your pulse points.
Performance is where this fragrance becomes a serious commitment. A single spray is often enough to fill a room, and it easily lasts over twelve hours on skin. On clothing, you will likely still smell the vanilla and sandalwood after a laundry cycle. It is a true powerhouse that requires a light hand during application, especially if you plan on wearing it in enclosed spaces.
This is a strictly cold weather scent. In the heat of summer, the sugar and praline would likely feel suffocating. It suits anyone who enjoys high-end gourmands but wants something with more structural integrity than a typical mall fragrance. While it leans slightly masculine due to the oakmoss and cognac, the vanilla and praline make it a comfortable choice for anyone who appreciates a bold, sweet profile.
Ultimately, Substance is a successful exercise in balancing extreme sweetness with dark resins and booze. It feels deliberate and high-quality, avoiding the thin, chemical finish of many modern gourmands. If you enjoy scents like Angel’s Share but want more hazelnut and a bit more earthiness, this is a strong contender for a full bottle purchase. Just be prepared for the attention its massive sillage will bring.
FAQs
What does Substance by Synesthesie smell like?+
Substance is a rich, boozy gourmand that centers on a prominent hazelnut and cognac pairing. It opens with a spirited alcoholic kick before settling into a warm heart of cinnamon, tonka bean, and cane sugar. The dry down is a deep, resinous blend of praline, vanilla, and myrrh. It feels like a thick, sweet amber with a sophisticated earthy edge from oakmoss.
How long does Substance last on skin?+
The longevity is exceptional, often exceeding twelve hours on skin. Because of the heavy base of myrrh, sandalwood, and vanilla, it clings to the wearer throughout the day and into the night. On fabrics, the scent can linger for several days. It is a high concentration fragrance that maintains its profile without fading into a generic skin scent too quickly.
Is Substance a good office fragrance?+
This is a very loud scent with significant sillage, so it may be too overwhelming for a standard office environment. The combination of cognac, cinnamon, and praline projects quite far, potentially distracting colleagues. If you must wear it to work, one light spray under your shirt is the safest approach to keep the projection within your personal space.
Which season is best for wearing Substance?+
Substance is designed for the colder months of autumn and winter. The warm spicy accords and dense sweetness of the praline and vanilla flourish in crisp air. In high temperatures, the sugar and cognac notes can become cloying and heavy. It is the perfect companion for a snowy evening or a chilly night out in November.
Does Substance lean more masculine or feminine?+
While marketed as unisex, it carries a slight masculine tilt due to the oakmoss and boozy cognac opening. However, the heavy presence of vanilla, sugar, and praline provides a sweetness that many women will find very appealing. It sits comfortably in the middle, making it a versatile choice for anyone who loves a powerful, resinous gourmand profile.
What are the main notes in Substance?+
The most recognizable notes are hazelnut and cognac in the opening, followed by a spicy heart of cinnamon and tonka bean. The base is heavily defined by praline and vanilla, with a distinct resinous touch of myrrh. A subtle earthy oakmoss and salty ambergris provide a background contrast that keeps the sweetness from becoming too one dimensional or childish.
How does the sillage of Substance compare to other scents?+
The sillage is enormous, especially during the first three hours of wear. It creates a noticeable scent trail that can fill a room easily. The combination of ambergris and white musk helps the heavier gourmand notes travel through the air. You should be cautious with the trigger, as this fragrance is much stronger than a typical eau de parfum.
Is this a safe blind buy?+
Due to the intensity of the myrrh and the boozy cognac opening, it is better to sample Substance first. While the hazelnut and praline are very likable, the massive performance and resinous dry down can be polarizing for those used to lighter scents. It is a bold statement piece that requires a specific taste for dense, ambery oriental fragrances.
How does Substance change from the opening to the dry down?+
It starts with a sharp, spirited cognac and a dry, toasted hazelnut. As it settles, the alcoholic edge fades, replaced by the warmth of cinnamon and the sweetness of cane sugar. In the final stage, several hours later, the fragrance becomes a creamy, balsamic blend of praline and vanilla. The earthy oakmoss provides a steady, subtle hum throughout the entire transition.
Can I layer Substance with other perfumes?+
Substance is so complex and powerful that layering it can be difficult. However, if you want to emphasize the woody side, a simple sandalwood or cedar based scent could work well. Avoid layering it with other sweet fragrances, as the praline and sugar are already very dominant. A clean musk could also help soften the intense projection of the boozy opening.
