7d • Note Spotlight
Rose 🌹
Today, I wanted to begin a new series exploring specific notes found in nature and how we recreate them in perfumery. While this series will occasionally venture into fantasy accords, the goal is to deepen our understanding of perfumery as a whole and remind ourselves that creativity should never have limitations.
The first note we'll explore is one of my personal favorites: rose.
Rose holds a very special place in my heart. I grew up surrounded by rose bushes, cutting fresh blooms as a child to bring to my grandmother, who always seemed to smell of roses herself. To this day, that aroma immediately brings back those memories.
Most people think of rose as a single, linear scent. In reality, nothing could be further from the truth. Nature is far more complex than that.
Before we talk about roses specifically, it's important to understand why flowers are fragrant in the first place. Floral aromas evolved primarily to attract pollinators. Different flowers produce different combinations of aromatic molecules that appeal to particular insects, birds, or other pollinating animals. This incredible diversity is why flowers can smell so vastly different from one another. Some are fresh, dewy, and unmistakably floral, while others can smell surprisingly spicy, fruity, citrusy, green, or even reminiscent of licorice or melon.
Over the years, I've spent countless hours visiting nurseries, botanical gardens, and dedicated rose gardens, studying hundreds of different cultivars. My goal wasn't simply to admire them—it was to understand how roses actually smell in nature rather than relying on the simplified idea of "rose" that perfumery often presents.
One observation I've made is that the color of a rose often gives clues about its overall aromatic character. This certainly isn't a strict rule, and there are countless exceptions depending on the variety, but it's an interesting trend I've noticed.
- Yellow Roses - Often the brightest-smelling of the group. Many have citrusy, lemony, or even melon-like nuances that can feel cheerful, sparkling, and surprisingly tropical.
- Red Roses - The classic "rose" profile. Rich, velvety, deep, and luxurious with the romantic character most people associate with roses.
- White Roses - Soft, delicate, clean, and often carrying a subtle musky or creamy quality rather than an intensely floral one.
- Purple (Lavender-Toned) Roses - In my experience, these tend to have a much lighter fragrance. Many are surprisingly delicate with soft floral nuances rather than a powerful aroma.
- Pink Roses - Somewhere between red and purple roses. They often combine the velvety richness of red varieties with a softer, more delicate floral character.
- Multicolored Roses - These are perhaps the most unpredictable. I've encountered some with almost no fragrance at all, while others lean toward the bright, citrusy character often found in yellow roses.
Of course, this doesn't apply to every rose. There are thousands upon thousands of cultivars, each with its own personality. These are simply my observations after years of smelling and studying roses in nature.
The more time you spend with real flowers, the more you begin to realize that there isn't just one smell of rose. There are hundreds. As perfumers, our job isn't simply to recreate "rose"—it's to decide which rose we want to bring to life.
Lets start with the major components that create rose. We have the main Alcohols (Citronellol, geraniol, Eugenol, Phenyl Ethyl Alcohol, Nerol, Linalool), Damascones/Damascenones, Terpenes (IE Myrcene, a-Terpineol), Rose Oxide, Ketones, Esters, and Aldehydes. With these basic components we can create a simple structured accord based on these alone.
Rose is actually a wonderful example of why natural fragrances are so difficult to recreate. There isn't a single "rose molecule"—instead, it's a complex mixture of hundreds of compounds, with a handful doing most of the heavy lifting. Those compounds come from several different chemical families, each contributing a different facet of the flower.
🌹 Alcohols
These make up the backbone of a classical rose aroma.
- Citronellol – Fresh, sweet, rosy, slightly citrusy. One of the most abundant components in many rose oils.
- Geraniol – Bright, fresh, rosy with hints of citrus and green.
- Nerol – Similar to geraniol but softer, fresher, and more delicate.
- Phenyl Ethyl Alcohol (PEA) – The quintessential "fresh-cut rose" smell. Soft, dewy, honeyed, and slightly green. This is often the first material people associate with realistic roses.
These four materials alone can produce something that is unmistakably rose-like.
🌹 Terpenes & Terpenoids
These provide freshness, lift, and natural complexity.
- Linalool – Floral, citrusy, slightly woody.
- Limonene – Bright citrus sparkle.
- β-Caryophyllene – Adds subtle spice and warmth.
- α-Pinene & β-Pinene – Green, pine-like freshness in trace amounts.
- Farnesol – Soft floral with a gentle woody sweetness that contributes elegance and longevity.
🌹 Esters
Esters contribute fruitiness and softness.
- Citronellyl acetate – Fruity, rosy, slightly pear-like.
- Geranyl acetate – Floral with fresh citrus nuances.
- Phenethyl acetate – Sweet, rosy, honeyed, almost candied floral.
These are especially important in roses that have fruity or tropical nuances.
🌹 Aldehydes
Rose doesn't contain huge amounts of aldehydes, but the ones present have a significant impact.
- Nonanal – Waxy citrus freshness.
- Decanal – Orange peel brightness.
- Citral (in some varieties) – Lemony freshness.
- Benzaldehyde (trace) – A faint almond-like sweetness.
These give the bloom its sparkling, airy quality.
🌹 Rose Oxides
One of the defining signatures of certain roses.
- Rose Oxide (cis & trans isomers)
Rose oxide has an incredibly low odor threshold. Even tiny amounts add an unmistakable rosy character with nuances of lychee, tropical fruit, citrus peel, and fresh greenery. Many modern perfumers rely on it to create realism because it gives rose its characteristic "lift."
🌹 Damascones & Damascenones
These are among the most powerful molecules found in roses.
- β-Damascenone – Rich, fruity, jammy, plum, honey, tobacco, dried fruit.
- α-Damascone – Fruity with berry and floral nuances.
- β-Damascone – Rose, black tea, tobacco, raspberry.
Although present only in trace amounts, they have astonishing potency. Without them, a rose accord often smells flat and lifeless. They create much of the richness and depth we associate with premium rose oils.
🌹 Ketones & Ionones
These contribute elegance and softness.
- β-Ionone – Violet, woody, slightly powdery.
- α-Ionone – Floral with a raspberry nuance.
These naturally arise from the degradation of carotenoids in the petals and help bridge rose toward violet and berry facets.
🌹 Phenols & Others
Present in tiny amounts but essential for realism.
- Eugenol – Clove-like spice.
- Methyl Eugenol – Sweet spice.
- Nerol Oxides
- Rose Furans
- Benzyl Alcohol
- Benzyl Acetate
These trace materials prevent a rose from smelling one-dimensional and help explain why some varieties smell spicy, tea-like, or even slightly fruity.
One of the biggest lessons in perfumery is that the materials present in the highest concentration aren't always the ones you notice the most. Compounds like β-damascenone and rose oxide exist at incredibly low concentrations in rose oil, yet because of their exceptionally low odor thresholds, they have a tremendous impact on the overall aroma. This is one of the reasons rose is such a fascinating material to study: a few trace molecules can completely change how we perceive the flower.
With this basic understanding of a rose's structure, we can begin to transform and manipulate an accord to reach whatever destination we have in mind. This is where perfumery becomes less about copying nature and more about interpreting it.
One of my favorite examples is a rose cultivar called 'White Licorice.' A Floribunda shrub in the Rosaceae family, introduced in 2009, it completely defies what most people expect a rose to smell like. Rather than the classic velvety floral aroma, it carries an unmistakable scent of black licorice and anise.
One of the compounds largely responsible for this unique character is 1,4-dimethoxybenzene (also known as dimethyl hydroquinone). While it occurs naturally in several flowers, it is particularly notable in this rose, giving it that sweet, anisic, licorice-like signature that makes it so memorable.
Another fascinating example is a rose called 'The Poet's Wife.' The first time I smelled it, I was genuinely caught off guard. Instead of a traditional rose profile, it exploded with the aroma of ripe honeydew melon wrapped in vibrant lemon and orange citrus. Had I smelled it blind, I may not have guessed it was a rose at all.
To my nose, I immediately pick up facets reminiscent of limonene and citral, creating that bright citrus opening. While, to my knowledge, no published headspace analysis exists for this particular cultivar, I was able to recreate something remarkably close by emphasizing citrus terpenes and adding just a trace of Melonal to capture that juicy honeydew effect.
Experiences like these remind me why I fell in love with perfumery in the first place. The more time you spend studying nature, the more you realize there is no single definition of what a rose should smell like. Every cultivar tells its own story, and every unexpected nuance becomes another tool in the perfumer's palette.
This is the part of perfumery I enjoy most—the exploration, the experimentation, and the constant discovery. Nature gives us the inspiration, but artistry allows us to take those ideas even further. There truly is no limit to what you can create when curiosity and creativity come together.
