What is e-liquid?
Let me start simply. E-liquid is the liquid used in an electronic cigarette. It's what produces the vapor you inhale.

Without e-liquid, an electronic cigarette simply wouldn't work. The liquid is heated by a resistor. It is then transformed into vapor.
Unlike conventional cigarettes, there is no combustion. That's a major difference. In my opinion, it's even one of the main reasons why many smokers turn to vape.
The e-liquid is contained in a small tank, often referred to as a "reservoir". clearomizer or pod depending on model.
When you vape, the resistance gently heats the liquid. An aromatic vapor is formed. You then inhale it.
Tout comme le choix d’un e-liquide dépend de vos préférences, le choix entre Wix ou Squarespace pour le SEO doit correspondre à vos objectifs.
Whether you sell e-liquids or services, the choice of your web platform, such as Wix or Squarespace, impacts your SEO.
If you sell e-liquids, understand the Wix referencing can help you optimize your online store.
I find this system quite ingenious. It reproduces a sensation similar to smoking, but in a different way.
Before going any further, we need to understand one essential point: this liquid is made up of several specific ingredients.
Even for specific products such as e-liquid, the price of an SEO article must be considered for effective communication.
And that's exactly what we're going to see now.
What is e-liquid made of?
An e-liquid generally contains four main ingredients. Their balance determines taste, steam and throat feel.
| Component | Main role |
|---|---|
| Propylene glycol (PG) | Aroma transport, throat sensation |
| Vegetable glycerin (VG) | Steam generation |
| Aromas | Giving flavor |
| Nicotine (optional) | Satisfying nicotine cravings |
Now let's get down to the details.
Even for specific products such as e-liquid, the SEO article price must be considered for good visibility.
Propylene glycol (PG)
Propylene glycol is a fluid, colorless, almost odorless liquid.
Its main role is to transport aromas. Thanks to it, flavors are more perceptible.
It also produces what vapers call hit. This is the sensation felt in the throat when you inhale the steam.
Personally, I find that PG gives a vape more akin to a conventional cigarette.
However, in large quantities, it produces less steam.
Vegetable glycerin (VG)
Vegetable glycerin is thicker. It is slightly sweet.
Its role is simple: generate dense steam.
If you see large clouds of vapor, it's often thanks to a high proportion of VG.
But there's a little compromise. The more VG, the sweeter the flavors can seem.
In my opinion, a good balance between PG and VG is often ideal.
Nicotine
Nicotine is optional. Not all e-liquids contain nicotine.
For ex-smokers, it plays an important role. It helps to avoid withdrawal.
Dosages generally vary between :
- 0 mg
- 3 mg
- 6 mg
- 12 mg
- 18 mg
The right dosage often depends on your past consumption.
I often advise beginners not to choose a rate that's too low. Otherwise, frustration can set in.
Flavors
The aromas give the e-liquid its personality.
They can be natural or artificial.
The diversity is impressive. Fruits, desserts, drinks, mint, tobacco... there are thousands of recipes.
Some blends are even highly original. We sometimes speak of flavours gourmet or exotic.
And it's precisely these differences in aroma that bring us to another important topic: types of e-liquids.
The different types of e-liquids
Not all e-liquids work in the same way.
Depending on your equipment and profile, some may be more suitable for you.
Here are the most common categories.
Classic E-liquids
These are the most common.
They use a classic PG/VG base with traditional nicotine.
They are ideal for beginner vapers.
E-liquids with nicotine salts
Nicotine salts offer faster absorption.
The sensation in the throat is often softer.
I find them interesting for heavy smokers switching to vape.
CBD E-liquids
These liquids contain cannabidiol (CBD).
They contain no nicotine.
Some people use them for their relaxing effects.
DIY E-liquids
DIY means Do It Yourself.
Here, you make your own e-liquid.
You're mixing it up:
- a PG/VG base
- aromas
- possibly nicotine
It's economical, but requires a little precision.
How to choose your e-liquid?
When you're just starting out, the choice can seem dizzying.
I know exactly what you mean. There are thousands of references.
To simplify things, I recommend focusing on three essential criteria.
Choosing the right nicotine level
Here's a simple rule.
| Cigarette consumption | Recommended rate |
|---|---|
| Less than 10 cigarettes/day | 3 to 6 mg |
| 10 to 20 cigarettes/day | 6 to 12 mg |
| More than 20 cigarettes/day | 12 to 18 mg |
Of course, this table is only indicative.
Every vaper is different.
Choosing the right PG/VG ratio
The ratio influences the sensation of vape.
Here are a few simple guidelines:
- 50/50 steam and flavor balance
- 70/30 PG/VG stronger flavors
- 30/70 PG/VG denser steam
Personally, I find the 50/50 very versatile.
Choose the flavor
Flavor is often the most subjective part.
Some ex-smokers prefer tobacco flavours at first.
Then, over time, they explore fruity or gourmet flavors.
I recommend testing several families.
This is often how you find your favorite e-liquid.

If you would like to learn more about this subject, I recommend that you consult the LPV brand.
The guide explains in detail how e-liquid works, the basics of vape and the various options available to vapoteurs.
The different flavors of e-liquids
The world of flavors is incredibly vast.
Here are the main categories.
Fruity flavors
Very popular.
Strawberry, mango, apple, red fruit...
They often offer a light, refreshing vape.
Gourmet flavours
These e-liquids imitate desserts.
Vanilla, caramel, cookie, crème brûlée...
Some blends are surprisingly realistic.
Mentholated flavors
Perfect for a feeling of freshness.
Cool mint, eucalyptus, intense menthol.
Tobacco flavors
They reproduce the notes of classic tobacco.
I think they are reassuring for new vapoteurs.
How to use e-liquid
It's very easy to use.
Here are the main steps:
- open the tank of your electronic cigarette
- pour e-liquid
- close carefully
- wait a few minutes
This waiting time allows the cotton to soak in properly.
Otherwise, you risk a burnt taste, quite unpleasant.
Is e-liquid dangerous?
It's a question many readers ask themselves.
And that's normal.
Vaporization is not totally harmless.
However, several studies indicate that it is much less harmful than traditional cigarettes.
Why?
Because there's no combustion.
Burning tobacco produces thousands of toxic substances.
With vape, we avoid many of these compounds.
In my opinion, the electronic cigarette remains a transition tool for smokers.
How much does e-liquid cost?
The price depends on several factors:
- the brand
- capacity
- the complexity of aromas
On average :
- a bottle of 10 ml costs between €4 and €7
- a bottle of 50 ml costs between €15 and €25
DIY can significantly reduce costs.
How to store e-liquid?
Conservation is often neglected.
However, it influences the quality of the liquid.
I recommend :
- keep bottle away from light
- avoid heat
- close tightly after use
An e-liquid can generally be stored 1 to 2 years.
Over time, the color may darken. This is normal.
E-liquid FAQ
Can an e-liquid expire?
Yes, an expiration date is indicated on the bottle.
After this date, aromas may lose their intensity.
Can you vape without nicotine?
Yes, that's right.
Many vapoteurs are gradually switching to nicotine-free e-liquids.
How long does a bottle of e-liquid last?
It all depends on your consumption.
On average, a 10 ml bottle will last 2 to 4 days.
Which e-liquid should you choose?
I often recommend :
- a ratio 50/50 PG/VG
- a simple taste
- the right nicotine level
Questions fréquentes sur les e-liquides
Qu’est-ce qui compose un e-liquide ?
Un e-liquide est généralement composé de quatre ingrédients principaux : le propylène glycol (PG), la glycérine végétale (VG), des arômes alimentaires et, facultativement, de la nicotine. Le PG et la VG forment la base, les arômes donnent le goût et la nicotine procure le hit en gorge et aide au sevrage tabagique. Certains e-liquides peuvent aussi contenir du CBD ou des sels de nicotine.
Comment choisir le bon taux de nicotine ?
Le choix du taux de nicotine dépend principalement de votre consommation de tabac antérieure. Si vous étiez un gros fumeur (plus d’un paquet par jour), un taux élevé (12-18 mg/ml) est recommandé. Pour les fumeurs modérés, un taux moyen (6-9 mg/ml) est souvent suffisant. Les petits fumeurs ou ceux qui souhaitent réduire leur dépendance peuvent opter pour des taux faibles (3 mg/ml) ou sans nicotine. L’objectif est de trouver le taux qui satisfait votre besoin sans provoquer de surdosage.
Quels sont les différents types d’e-liquides disponibles ?
Il existe plusieurs catégories d’e-liquides pour s’adapter à toutes les préférences. Les e-liquides classiques sont les plus courants, avec une base PG/VG variée. Les e-liquides aux sels de nicotine sont conçus pour une absorption plus rapide et un hit plus doux, idéaux pour les anciens gros fumeurs ou les pods. Les e-liquides au CBD offrent les bienfaits du cannabidiol sans nicotine. Enfin, le DIY (Do It Yourself) permet de créer ses propres e-liquides en mélangeant base, arômes et nicotine selon ses goûts.
Comment bien conserver mon e-liquide ?
Pour préserver la qualité et les arômes de votre e-liquide, il est essentiel de le conserver correctement. Gardez-le dans un endroit frais et sec, à l’abri de la lumière directe du soleil et des variations de température. La chaleur et la lumière peuvent altérer les arômes et dégrader la nicotine. Assurez-vous également que le flacon est bien fermé pour éviter l’oxydation. Une bonne conservation garantit une meilleure expérience de vape sur le long terme.
