Fragrance Notes Explained: What Are Top, Middle and Base Notes?

Have you ever read a fragrance description and wondered what on earth the difference is between top notes, middle notes and base notes?

You might see a fragrance described as having bright citrus top notes, an aromatic heart and a warm, woody base. It sounds lovely, but what does it actually mean? And how does understanding these notes help you choose a candle, wax melt or home fragrance you'll love?

Don't worry — you don't need a perfumery degree to understand it! Let's break it down.

What Are Fragrance Notes?

Fragrance notes describe the different scents that make up a fragrance, from bright citrus and fresh herbs to florals, spices and warm woods.

They're often grouped into three categories: top, middle and base notes. Together, they help describe a fragrance's overall character and how its different elements complement one another.

Think of the fragrance pyramid as a helpful guide rather than a strict set of rules — not every fragrance develops in three distinct stages.

Top Notes: The First Impression

Top notes are often the first scents you notice. They're generally bright, fresh and lively, creating that initial impression when you encounter a fragrance.

Common examples include lemon, lime, bergamot, mint and light fruity aromas.

These notes can bring a fragrance to life, adding freshness and sparkle before the deeper characteristics become more noticeable.

Think: fresh, sparkling, crisp and uplifting.

Middle Notes: The Heart of the Fragrance

Middle notes, sometimes called heart notes, help define a fragrance's central character. They often become more noticeable as the initial brightness of the top notes softens.

You might find floral notes like rose and jasmine, aromatic herbs, spices or fruity accords in this part of the fragrance.

Middle notes help bring the different elements together, creating balance and giving the fragrance its personality.

Think: rounded, expressive, floral, fruity or aromatic.

Base Notes: The Deeper Foundation

Base notes provide depth, warmth and substance. They're often associated with richer scents such as sandalwood, cedarwood, patchouli, musk, amber and vanilla.

These notes can help balance brighter or lighter elements, creating a fragrance that feels more rounded and complete.

Although base notes are traditionally associated with the later stages of a fragrance, they can still be noticeable from the beginning — particularly in candles and home fragrance.

Think: warm, rich, smooth, woody and comforting.

How Do the Three Work Together? Let's Look at Aussie Bush!

One of the easiest ways to understand fragrance notes is to look at a real example — and what better choice than Aussie Bush, Wax & Lye's best-selling fragrance?

Aussie Bush combines fresh citrus, Australian-inspired aromatics and earthy woods to create a fragrance with a distinctly outdoorsy character.

Top notes — Lemon and Pine Needle

Bright, zesty lemon meets crisp, green pine needle to create a fresh first impression.

Middle notes — Eucalyptus and Lemon Myrtle

Eucalyptus brings its familiar cool, aromatic character, while lemon myrtle adds a distinctive citrusy, herbal note.

Base notes — Patchouli and Sandalwood

Earthy patchouli and warm, woody sandalwood provide depth and balance the brighter notes.

Together, these six notes create a fragrance that's fresh and green, with a warm, earthy foundation. It's a great example of how individual notes work together to create something more complex than any one scent alone.

Do Fragrance Notes Work Differently in Candles and Wax Melts?

Fragrance notes are often discussed in perfumery, where a scent may develop over time on the skin. In candles and wax melts, the fragrance is released into the air, and it won't necessarily unfold in the same distinct stages.

The way a fragrance smells can vary depending on the product, its use and your own perception. Understanding the notes is still a useful way to get a feel for a fragrance before choosing it, particularly when shopping online.

A Little About the Fragrances We Choose

At Wax & Lye, fragrance is an important part of what we do. After all, the right scent can turn an everyday product into something you look forward to using.

For the past ten years, we've sourced our fragrance oils from the same Australian supplier. That long-standing relationship is important to us, helping us maintain a consistent approach to fragrance selection across our range.

We also take care to choose fragrances that meet the relevant International Fragrance Association (IFRA) Standards for their intended applications. These standards help guide the safe use of fragrance materials in different types of products.

For us, it's all part of being thoughtful about the ingredients we use and creating products we're proud to put our name on.

How to Choose a Fragrance You'll Love

Not sure where to start? Think about the scents you naturally gravitate towards.

• Fresh and clean: Citrus, fresh herbs and airy, marine scents.
• Floral: Rose, jasmine and gardenia.
• Sweet and cosy: Vanilla, caramel and warm spices.
• Earthy and woody: Sandalwood, patchouli, musk and amber.

These categories are a handy starting point, but fragrance is personal. Notes can smell quite different when blended together, so don't be afraid to try something outside your usual favourites!
