Vape aromas, also called flavour concentrates, are the intense liquid tastes you add to a base to make your own e-liquid. In short, they are the flavour without the base or nicotine, so they let you build any recipe you like at a fraction of the cost of ready-made juice. Because a little goes a long way, one bottle of aroma makes far more e-liquid than it looks. This guide explains what vape aromas are, how much to use, and how to mix them into a finished bottle.
What are vape aromas?
A vape aroma is a highly concentrated flavouring made for mixing e-liquid. Essentially, it is the taste on its own, with no base and no nicotine, which is why it is far too strong to vape neat. To use it, you add a small amount to a base so the flavour ends up at a sensible level. Because the concentrate is so strong, a 30ml bottle of aroma can flavour several times its own volume of finished liquid. Therefore aromas are the most cost-effective way to keep your favourite flavours topped up.
You will also see aromas sold as longfills, where the concentrate sits in a larger bottle you top up with base. If that format appeals, our longfill explained guide covers it in full.
Aromas, longfills and concentrates: what is the difference?
These terms overlap, so it helps to separate them. An aroma or concentrate is pure flavour that you measure into a base yourself. A longfill is the same idea in a bigger bottle, already part-filled so you just add base to a line. As a result, the choice comes down to how hands-on you want to be.
| Type | What it is | Effort |
|---|---|---|
| Aroma / concentrate | Pure flavour you add to a base | You measure the percentage |
| Longfill | Concentrate in a larger bottle | Top up with base to the line |
| Premix | Fully finished e-liquid | None, ready to vape |
So if you enjoy tweaking your mix, aromas give the most control. However, if you want less measuring, a longfill is the easier route to the same flavour.
How much aroma should you add?
Getting the percentage right is the whole skill, and it is easier than it sounds. As a rule, most fruit aromas work well around 10 to 15 percent of the final mix, while richer dessert, tobacco or cream flavours often need a little more. Meanwhile, menthols usually sit at the lower end because they are so punchy. Since every concentrate is different, always follow the mixing percentage printed on the bottle.
| Flavour type | Typical percentage |
|---|---|
| Fruit and menthol | Around 10 to 15% |
| Dessert, cream and tobacco | Around 15 to 20% |
| Mixing two aromas | Keep the combined total in range |
One golden rule makes life easier: start low, because you can always add more, but you cannot take flavour out once it is in.
How to mix an aroma into a base
With the percentage sorted, mixing is quick. The base does the heavy lifting, and you simply add flavour and, if you want it, nicotine. Here is the reliable method.
- Decide your final volume and your flavour percentage, then work out the millilitres.
- Pour the aroma into a clean empty bottle first, measuring by syringe or the bottle markings.
- Add a nic shot next if you want nicotine, then top up with base to your final volume.
- Seal the bottle and shake it hard so the flavour blends evenly.
- Let it steep if needed, then fill your pod and enjoy.
To take the maths out of it, run your recipe through the nicotine strength calculator. You will also need a base and, ideally, the tools in DIY accessories.

Tips for better flavour
A few small habits make homemade e-liquid taste noticeably better. First, always measure by percentage rather than by eye, since a couple of extra millilitres can overpower a whole batch. Secondly, shake thoroughly, because the concentrate needs to disperse fully through the base. Finally, some flavours improve with steeping, so leaving a dessert or tobacco mix to rest for a few days lets the taste round out.
Start low
Mix at the lower end of the percentage first. You can always add a little more next time.
Blend flavours
Combine two aromas for your own signature mix, but keep the total percentage in range.
Steep the rich ones
Fruit is often ready straight away, while creams and tobaccos reward a few days resting.
The verdict
Vape aromas are the cheapest, most flexible way to keep your favourite flavours flowing, because one small bottle makes a lot of e-liquid. Once you know the right percentage and add it to a good base, you can recreate any taste you love or invent your own. Start with a fruit blend at the lower end of the range, shake well, and steep the richer mixes. When you are ready to build a bottle, browse the full aromas range and pair it with a base.
Frequently asked questions
What is a vape aroma?
A vape aroma is a concentrated flavour used to make e-liquid. It contains no base and no nicotine, so it is too strong to vape on its own. You add a small percentage to a VG/PG base to create a finished, flavoured e-liquid.
How much aroma do I add to a base?
Most fruit and menthol aromas work at around 10 to 15 percent of the final mix, while richer dessert and tobacco flavours often need 15 to 20 percent. Always follow the percentage on the bottle, and start low because you can add more but cannot take it out.
Can I vape an aroma on its own?
No. Aromas are far too concentrated to vape neat and could taste harsh or unpleasant. They are designed to be diluted into a base at a small percentage, which brings the flavour down to a comfortable level.
What is the difference between an aroma and a longfill?
An aroma is pure concentrate you measure into a base yourself. A longfill is the same concentrate in a larger bottle, already part-filled so you simply top it up with base to a set line. A longfill needs less measuring, while separate aromas give more control.
Do vape aromas contain nicotine?
No. Aromas and flavour concentrates are nicotine-free. If you want nicotine in your finished e-liquid, you add it separately with a nic shot when you mix, so you control the exact strength.
How long do vape aromas last?
Sealed and stored cool and dark, a concentrate keeps for a long time, often a year or more. Heat and light slowly dull the flavour, so keep bottles closed and out of sunlight to protect them.

For adult vapers (18+) only. Vape aromas and concentrates are nicotine-free on their own; any nicotine you add with a nic shot is addictive. Handle nicotine with care, check the strength and your local limit, and keep all mixing supplies away from children and pets.
