Scent Profiles Explained

Scent profiles

Why do we love it or hate it?

When you first start exploring fragrance oils, it can feel like learning a whole new language. Terms like “top notes,” “mid notes,” and “base notes” get thrown around a lot, but what do they actually mean? And why doesn’t everyone smell the same thing?

At Aussie Candle Supplies, with over 20 years of experience working with fragrance oils across candles, soaps, and home fragrance, we’ve seen firsthand just how fascinating and personal the world of scent can be.

Understanding Scent Profiles

A fragrance is often described as a scent profile, made up of layers, top, middle, and base notes that unfold over time.

• Top notes: The first impression, light, fresh, and quick to appear (think citrus or herbs)
• Middle notes (heart notes): The body of the fragrance, florals, fruits, or spices that define the character
• Base notes: The foundation, rich, deep notes like vanilla, woods, or musk that linger

These layers work together to create the full fragrance experience, rather than existing as separate, isolated smells.

Why Not Every Note Is Listed

In our experience, fragrance notes are based on the raw materials used to create the oil. However, not every ingredient can or should be listed in a description.

Instead, scent descriptions are carefully simplified into top, middle, and base notes to give you a clear and practical guide. Think of it as a curated snapshot of the fragrance, rather than a full ingredient breakdown.

Fragrance Is Subjective (And That’s Normal)

Here's something really important: no two people smell a fragrance in exactly the same way, and this comes down to how our olfactory system processes scent.

This can depend on:

• Personal scent sensitivity
• Memory and emotional associations
• Environment and surroundings
• The way the fragrance is used (oil vs candle vs soap)

So, while one person might clearly pick up lavender or vanilla especially when used as a pure essential oil, another might notice something completely different.

And that’s completely normal.

From Raw Oil to Finished Product

Our fragrance descriptions are developed based on how the oil is designed to perform over timehow the top, middle, and base notes evolve.

But performance can shift depending on the application, for example, in candle making, heat throw can change how notes are released, wax type can influence scent balance, and cure time can affect how fully a fragrance develops.

It’s quite common for:

• Brighter top notes to soften
• Deeper base notes to become more prominent

This means a fragrance oil may smell slightly different in a candle compared to how it smells straight from the bottle.

What Fragrance Notes Really Represent

Fragrance notes aren’t meant to be a literal or exhaustive list of ingredients. Instead, they’re designed to communicate the overall sensory impression of a scent.

At Aussie Candle Supplies, our notes are developed collaboratively by our perfumery team and evaluation specialists. This process involves:

• Assessing the fragrance as a whole
• Identifying the most recognisable scent characteristics
• Communicating the scent characteristics within the description

The goal is simple: to give you the best possible idea of what to expect, in a way that’s easy to understand.

A Helpful Way to Think About It

Rather than asking, “Can I smell every listed note?”
It’s more useful to ask, “Does this fragrance feel like the description overall?”

Because in the end, fragrance is not just chemistry, it’s experience.

Final Thoughts

Fragrance notes are a guide, not a guarantee. They’re there to help you navigate the scent journey, not define it down to the smallest detail.

With over two decades of experience, we always recommend sampling where possible because the most important opinion is ultimately your own.

And remember in the world of fragrance, there’s no right or wrong, just what works for you.

Frequently Asked Questions

Why does a fragrance oil smell different in a candle than in the bottle?

Heat changes how top, middle and base notes are released, brighter top notes often soften while deeper base notes become more prominent once the candle is burning.

Why can't I smell every note listed in a fragrance description?

Notes are a simplified, curated guide to the overall scent impression, not a literal ingredient list so not every raw material used is called out individually.

Why does everyone describe a scent differently?

Fragrance perception is subjective and shaped by personal scent sensitivity, memory, environment, and even the application (oil vs. candle vs. soap), so no two people experience a scent identically.

Does cure time affect how a fragrance smells?

Yes. Cure time allows a fragrance to fully develop within the wax, so a candle tested too early may smell different, often weaker or less balanced than the same candle after proper curing.

What's the difference between top, middle and base notes?

Top notes are the first, light impression (citrus, herbs); middle notes form the body of the fragrance (florals, fruits, spices); base notes are the deep, lingering foundation (vanilla, woods, musk).
