Let's Mix It Up

With a bit of know-how and a little creativity, anyone can become a fragrance mixologist! Read on for tips to get you started, and snag some of our tried-and-true fragrance oil blend recipes to begin your blending adventure.

When it comes to blending fragrances, there is no right or wrong. 

As you begin working with scents regularly, you’ll find that your nose for fragrance gets more and more refined. Just like with food and wine, as you’re working with and paying attention to the subtleties of different aromas, the more you’ll find your sense of smell evolving. Blending is a great way to “exercise” your nose and allows you to tweak fragrances to your own tastes and create your own candle scents. Not to mention...it’s just plain fun!  

That said, it can seem a little intimidating to get started. But never fear, anyone can become a fragrance mixologist—all it takes is a bit of know-how and a little creativity.

The language of fragrance

When we describe the character of a fragrance, we talk about it in terms of top notes, middle notes, and base notes. The way the fragrance notes combine is what gives every scent its own unique profile. 

  • The top notes of a fragrance are what you smell first, the aromas that give you an initial impression and draw you in. Top notes are usually lighter in smell and tend to be citrusy or soft florals. These are the most volatile notes, meaning that they tend to fade more quickly than the others. 

  • The middle notes, also referred to as the “heart,” provide balance between the top and base notes. These are usually bright florals, gourmands, fruits, or lighter woods. The middle notes are usually the most prominent aromas you will smell when a candle is burning.  

  • Base notes are the anchor of every fragrance, lending depth and longevity to the aroma. Typically these notes will be things like vanilla, spices, musks, woods, or amber. These are the notes that tend to linger in a room after a candle is extinguished and leave a lasting impression of the scent. 

Paying attention to the fragrance notes is a great way to identify good scent combinations you might want to try—and it also helps develop your nose!

PRO TIP: The Fragrance Finder isn’t just a fun way to discover new fragrances, it’s also a great tool to have in your blending toolbox. Limit to just the fragrances with the specific notes you’re looking for or by categories like Fresh & Clean, Woods, and Spice.

Blending basics

When you’re thinking about fragrance blends you want to try, we recommend starting with fragrances with which you already have some familiarity. Having that knowledge of how a standalone scent performs regarding the cold and hot throws will help you perfect your desired blend more easily.  

The best way to begin your blending adventure is by jumping right in! Using blotter strips is a quick and easy way to test out different fragrance combinations and start training your nose to pick out the notes. Here’s how to use them:

  1. Dip the blotter into the fragrance bottle, using the red lines at the tip to guide you. If you want one fragrance to have a stronger presence, dip that one to the second line. If you want a 50/50 blend, dip both to the first line. 
  2. Allow the blotter strips to dry for about 10 seconds.
  3. Hold the blotters together and fan them under your nose a few times until you get a good impression of the blend.

PRO TIP: Take detailed notes as you're testing out your fragrance oil blend ideas. Make note of the scents combos you've tried, the ratios, whether you tested it in a candle, etc. 

You’re probably ready to test out a few of your blend ideas, but first...

What makes a fragrance a good blender?

That’s simple: simplicity! When you’re learning and getting your process down try to stick to more basic scents for the best results. If you do want to try a blend with a more complex fragrance, make sure to keep the other fragrance/s simple. 

These fragrances are gorgeous on their own, but they’re also fantastic blenders:

The benefits of blending

Fragrance blending is lots of fun, but it’s also a great way to differentiate your brand. Custom scents that can’t be found anywhere else entice customers to return again and again. Not to mention, you can create an entirely new fragrance library without the need to buy, test, and evaluate new fragrances! 

Blending is also the perfect opportunity to flex those creative muscles! Scent blends can spark some attention-grabbing fragrance names, label designs, and other fun branding ideas. To get you started, here are a few candle scent name ideas we came up with for autumn and Halloween-themed fragrances.
