What does caramel smell like? The sweet heart of gourmand perfume

Caramel is one of the easiest smells in the world to recognise. It is the smell of a fairground, a sweet shop, a pan of sugar turning golden on the stove. In perfume, it is the note that made "edible" scents famous. Some people find it cosy and comforting. Others find it too sweet. Either way, once you know how caramel works in a fragrance, you will start to spot it everywhere.

What does it smell like?

Warm, sweet and slightly burnt. A caramel note in perfume usually has several sides:

• Burnt sugar: a toasty, golden sweetness, a little bitter at the edges
• Butter and cream: a soft, milky richness, like toffee or fudge
• Candy floss: a light, sugary, fairground fluffiness
• Fruit jam: a jammy, strawberry-like sweetness in some caramel materials
• Toast and nuts: a roasted, almost bready warmth

Caramel changes a lot with its partners. With salt and woods it feels grown-up and smooth. With fruit and flowers it feels playful and sugary. With patchouli or coffee it turns dark and dramatic.

Where it comes from

Caramel is not a plant. It is something that happens to sugar.

When sugar is heated slowly, to around 170°C for ordinary table sugar, it melts and starts to break down. This process is called caramelisation. The sugar turns from clear to gold to brown, and hundreds of new aroma compounds form. Many of them smell sweet, buttery and toasty. When milk or cream is added, as in toffee and soft caramels, the smell becomes richer and rounder.

Some of the same caramel-like molecules also appear naturally in other foods. Maltol is found in roasted malt and in the bark of larch trees. Furaneol helps give ripe strawberries their sweet, caramel-like smell.

How it's made

You cannot squeeze caramel into a bottle. Real cooked caramel does not work as a perfume ingredient, so perfumers build a caramel accord, a blend of materials that together smell like caramel.

The main building blocks are:

1. Ethyl maltol. The star of most caramel accords. It smells intensely sweet, like caramel, candy floss and fruit jam. A tiny amount goes a long way.
2. Maltol. A close relative of ethyl maltol. It is softer and weaker, with a warm, bready, toasted-sugar smell.
3. Furaneol. Sweet and jammy, with hints of caramel and strawberry. It adds a fruity, cooked-sugar feel.
4. Vanilla materials. Vanillin and ethyl vanillin give the creamy base that most caramel accords sit on.
5. Resins and balsams. Benzoin, labdanum and tonka add a warm, ambery depth so the caramel lasts on skin.

By changing the balance, a perfumer can make caramel that feels light and sugary, or dark, buttery and almost burnt.

A short history of caramel

• In the kitchen: People have cooked sugar into sweets for centuries. The English word "caramel" came from French, which took it from Spanish caramelo in the 18th century.
• Salted caramel: Salted butter sweets were a tradition in Brittany, in north-west France. In 1977, the confectioner Henri Le Roux created a salted butter caramel in Quiberon that helped make the flavour famous. By the 2000s, salted caramel had spread to cafés and ice cream around the world.
• In flavour chemistry: Maltol was known to flavour chemists long before it reached perfume. Ethyl maltol, a stronger cousin, later became a common food and sweet flavouring.
• In perfume: For most of perfume history, sweet notes came from vanilla, tonka and resins, not from candy. That changed in the 1990s, when perfumers began using ethyl maltol in large amounts.

Caramel in modern perfume

The turning point was Angel by Thierry Mugler (1992), created by perfumer Olivier Cresp. It paired a big dose of patchouli with a sweet, ambery accord built around ethyl maltol. The result smelled of candy floss, caramel and chocolate, but also dark and earthy. Angel is often called the first modern gourmand perfume, meaning a perfume that smells like something good to eat.

Angel opened the door. A*Men by Thierry Mugler (1996), by Jacques Huclier, brought caramel and coffee into men's perfume. Prada Candy by Prada (2011), by Daniela Andrier, put a soft caramel over benzoin and musk. Today caramel is a common note in sweet, cosy perfumes for everyone.

Real vs synthetic caramel

Nearly every caramel note in perfume is synthetic, or built from a mix of synthetics and natural resins.

• Natural options are limited. There is no practical "caramel oil". Perfumers can hint at caramel with natural materials like benzoin, tonka and labdanum. Fenugreek extract adds a maple-syrup sweetness, thanks to a molecule called sotolon.
• Synthetic caramel relies on ethyl maltol, maltol, furaneol and vanillin. These are what give a perfume its clear, sugary, unmistakable caramel smell.

This is a case where synthetics do something nature cannot. Without them, the gourmand family as we know it would not exist.

What caramel pairs well with

• Vanilla and tonka: the classic creamy base. Caramel sits on top like a glaze.
• Patchouli: the Angel combination. Earthy patchouli stops caramel from feeling childish.
• Coffee: roasted and bitter against sweet. Think of a caramel latte.
• Sea salt: a modern salted-caramel effect that feels less sugary.
• Tobacco and benzoin: warm, ambery and smoky, for a richer, more adult caramel.
• Orange blossom: a bright floral that lifts caramel and keeps it from feeling heavy.

Perfumes to try

Start light, then go sweeter and darker:

• Prada Candy by Prada (2011): soft caramel, benzoin and musk. Sweet but smooth.
• Love, Don't Be Shy by Kilian (2007): orange blossom, marshmallow and caramel. Fluffy and floral.
• Angel by Thierry Mugler (1992): the classic. Caramel-like sweetness with loud patchouli.
• A*Men by Thierry Mugler (1996): caramel and coffee in a bold men's scent.
• Daim Blond by Serge Lutens (2004): mostly a suede scent, with a soft toffee note in the base. A subtle way to try it.

How to wear caramel

• Go easy. Caramel notes are strong and long-lasting. One or two sprays is often enough.
• Pick your season. Caramel shines in autumn and winter, when warmth feels welcome. In heat it can feel sticky.
• Look for balance. If pure sweetness feels too much, choose caramel paired with salt, woods, coffee or patchouli.
• Test on skin. Caramel often smells sharper and more sugary on paper than on warm skin.

Who will love it

Anyone with a sweet tooth, fans of cosy, comforting perfume, and people who like a scent that gets noticed. If you think caramel is "too sweet", try a salted or coffee-caramel scent first. It may surprise you.
