Fragrances aren’t something you experience in one instant. They have different components that become apparent over time. One of the things that you should know if you want to learn about perfumery is how a fragrance is broken down into stages, and we call them notes.
A fragrance has three main components: top notes, heart notes, and base notes.
So what are fragrance notes?
A fragrance is a mixture of several different ingredients. While some ingredients will be noticeable right away, others will emerge more slowly and persist longer.
There is a convention of grouping these ingredients into three categories, top notes, heart notes, and base notes, which can help us talk about how a fragrance evolves over time.
Top Notes
These are usually the ingredients you first notice when you put on a fragrance.
Top notes are usually lighter, and more volatile, which means they will evaporate relatively quickly.
What kinds of ingredients do top notes consist of?
Ingredients like bergamot, lemon, and grapefruit are frequently found in top notes. You might also find fresh green notes like mint or basil, as well as some aroma materials.
Top notes set the initial character of a fragrance, and are a key part of the first impression.
Heart Notes
As the top notes start to fade, the heart notes become more apparent. These form the core of the fragrance, and they will usually last longer than top notes.
What kinds of ingredients do heart notes consist of?
Some of the most common heart notes are floral and spicy ingredients like rose, jasmine, lavender, geranium, cinnamon, pepper, etc.
That said, there are no hard rules about what can go into the heart of a fragrance, and modern perfume often uses unexpected combinations of ingredients.
Base Notes
Base notes will emerge more slowly and can last a long time. They will add depth to the fragrance and contribute to the final character of the composition.
What kinds of ingredients do base notes consist of?
Woody notes, resins, vanilla, and musks are common ingredients found in base notes, though other ingredients that don’t evaporate very quickly are often used too.
Note that some base notes might change how we perceive the earlier parts of a fragrance as it develops over time.
How Top, Heart, and Base Notes Work Together
Keep in mind that top, heart, and base notes are not completely separate fragrances; they work together. A citrus top note can merge with a floral heart note, which then blends with a warm woody base. This transition is a big part of what makes a fragrance interesting.
Strong fragrances don’t always have to have dramatic differences between each part; sometimes the most effective fragrances are those that allow different ingredients to work together to build up to a final impression.
Why Does the Scent Change Over Time?
A fragrance will evolve over time due to the evaporation rates of the different ingredients, the concentration of the fragrance, the state of your skin, the weather, and many other factors. That’s why smelling a perfume right after you put it on isn’t always representative of the whole fragrance.
How Should I Smell a Perfume?
Smell a perfume shortly after putting it on, and then again later. Think about which ingredients have faded, which ones have emerged, and how the fragrance as a whole has changed.
Learning to Talk About Fragrance
If you can develop your ability to talk about the notes of a fragrance, it can be easier to evaluate whether you like it. Instead of just saying whether it smells good or bad, you might say it smells “citrusy,” “powdery,” “woody,” “floral,” “green,” “spicy,” “creamy,” “fresh,” “smoky,” “warm,” etc. The more you smell a fragrance, the better you will get at identifying different notes.
Summary
The concept of top, heart, and base notes is a great way to start understanding how perfumery works. Don’t judge a fragrance based on how it smells immediately after you put it on. Look at the different characteristics and how they work together. The more you pay attention to your sense of smell, the easier it will be to distinguish a fragrance’s different components, and eventually to imagine creating your own.
