E-Liquid UK: The Ultimate Guide to Vape Juice
Welcome to the world of e-liquid! Whether you call it vape juice, vape liquid, or e-liquid, it’s the essential ingredient that makes vaping possible. With thousands of flavours, strengths, and types available, choosing the right one can feel overwhelming for new and experienced vapers alike. This guide is here to change that. We'll break down everything you need to know to understand vape juice, from VG/PG ratios and nicotine types to choosing the perfect flavour for your kit, so you can buy with confidence.
What is E-Liquid? Your Quick Start Guide
At its core, e-liquid is the fluid that your vape kit or device heats up to create the vapour you inhale. While the variety is immense, the basic composition is surprisingly simple. E-liquid, vape juice, and vape liquid are all different names for the same product, so don't let the terminology confuse you. It typically consists of just four main ingredients that work together to deliver flavour and nicotine (if you choose to use it).
The 4 Core Ingredients Inside Your Vape Juice
Understanding what’s in your vape juice is the first step to choosing the right one. Here’s a look at the four components you'll find in almost every bottle:
- Propylene Glycol (PG): This is a thin, colourless liquid that is excellent at carrying flavour. It also provides the "throat hit," a sensation that many former smokers look for, which mimics the feeling of smoking tobacco.
- Vegetable Glycerin (VG): VG is a thicker, slightly sweet liquid derived from vegetable oils. Its primary role is to produce the visible vapour or "clouds." The more VG in a liquid, the denser the clouds will be.
- Food-Grade Flavourings: All the delicious tastes in e-liquids, from apple to vanilla custard, come from concentrated flavourings. These are the same high-quality, food-grade flavourings used in products like sweets, drinks, and baked goods.
- Nicotine: This is an optional ingredient. E-liquids come in a wide range of nicotine strengths, from a strong 20mg all the way down to 0mg for those who vape purely for the flavour and experience.
How to Choose the Right E-Liquid for Your Vape Kit
Matching your e-liquid to your vape kit is the single most important factor in having a great vaping experience. Using the wrong type can lead to poor flavour, burnt coils, or even a leaking tank. The key to getting it right is understanding the relationship between your device's style and the e-liquid's VG/PG ratio.
PG vs VG: Finding Your Perfect Balance
The ratio of Propylene Glycol to Vegetable Glycerin determines how an e-liquid behaves. A high PG liquid will be thinner and produce less vapour but more flavour and throat hit, while a high VG liquid will be thicker, smoother, and produce much larger clouds.
| Feature | High PG E-Liquid (e.g., 50/50) | High VG E-Liquid (e.g., 70/30) |
|---|---|---|
| Throat Hit | Stronger, more like a cigarette | Smoother and milder |
| Cloud Production | Discreet, less vapour | Large, dense clouds |
| Flavour | Clearer and more intense | Slightly muted, often sweeter |
| Best For | Pod Kits & MTL Vapes | Sub-Ohm Kits & DTL Vapes |
E-Liquids for MTL (Mouth-to-Lung) & Pod Kits
Mouth-to-Lung (MTL) devices, which include most starter kits and pod systems, are designed to replicate the sensation of smoking. They use low power and have tight airflow. For these kits, the best choice is a 50/50 VG/PG e-liquid or a Nicotine Salt e-liquid. Their thinner consistency is easily absorbed by the small coils in these devices. You should avoid High VG liquids, as their thickness can clog your coils, leading to a burnt taste and a ruined coil.
E-Liquids for DTL (Direct-to-Lung) & Sub-Ohm Kits
Direct-to-Lung (DTL) devices, often called sub-ohm kits, are powerful vapes designed for creating large clouds of vapour. They use high power and have wide-open airflow. The best e-liquid for these kits is a High VG liquid, typically with a ratio of 70/30 VG/PG or higher. The thickness of VG is perfect for these powerful devices. Using a thin, High PG liquid in a sub-ohm tank will likely result in a harsh, unpleasant vape and may cause the tank to leak.
Nicotine Explained: Freebase vs. Nic Salts
Once you've matched your VG/PG ratio to your kit, the next step is choosing your nicotine type and strength. This choice significantly affects the sensation of your vape and how satisfying you find it, especially if you're switching from smoking.
What is Freebase Nicotine?
Freebase is the original form of nicotine used in e-liquids and is what most vapers are familiar with. It provides a noticeable "throat hit," which becomes more pronounced at higher strengths. This is the ideal choice for vapers who enjoy that classic sensation and typically use low to medium strengths like 3mg, 6mg, or 12mg in either MTL or DTL devices.
What are Nicotine Salts (Nic Salts)?
Nicotine Salts (or nic salts) are a newer form of nicotine that has been formulated to be much smoother on the throat, even at the highest strengths. They are also absorbed into the bloodstream more quickly than freebase nicotine, delivering a faster and more satisfying nicotine hit, similar to that of a cigarette. This makes them perfect for new vapers using pod kits or anyone who needs a higher strength like 10mg or 20mg without the harshness. Browse our full range of nic salt e-liquids to find a smooth and satisfying option for your pod kit.
How to Pick The Right Nicotine Strength
Choosing the right strength is personal, but a good starting point is to base it on your previous smoking habits. Getting this right will make your transition to vaping much smoother and more successful.
| Previous Smoking Habit | Recommended Strength | E-Liquid Type |
|---|---|---|
| Heavy Smoker (20+ per day) | 18mg - 20mg | Nicotine Salts |
| Medium Smoker (10-20 per day) | 10mg Nic Salts or 6mg - 12mg Freebase | Nicotine Salts or 50/50 E-Liquid |
| Light Smoker (Fewer than 10 per day) | 3mg - 6mg Freebase | 50/50 or High VG E-Liquid |
UK E-Liquid Bottle Types: 10ml vs. Shortfills
In the UK and EU, regulations (the TPD/TRPR) place restrictions on how e-liquid containing nicotine can be sold. This has led to two main types of e-liquid bottles that you will find in our store and across the country: 10ml bottles and larger shortfills.
10ml TPD E-Liquids: Ready to Vape
Under UK law, any e-liquid that contains nicotine can only be sold in bottles no larger than 10ml. These bottles are perfect for convenience as they come pre-mixed and ready to vape. They are available in the full spectrum of nicotine strengths, from 3mg up to the maximum legal limit of 20mg, making them the go-to choice for MTL vapers and anyone who wants a simple, grab-and-go solution.
Shortfills: Bigger Bottles, 0mg Nicotine
Shortfills are larger bottles of e-liquid (e.g., 50ml or 100ml) that contain zero nicotine. They get their name because they are deliberately "short-filled," leaving a gap at the top of the bottle. This space is for you to add a 10ml nicotine shot, a flavourless nicotine e-liquid, to create a large batch of low-strength e-liquid, usually 3mg. This is the most cost-effective way for sub-ohm vapers to buy their favourite High VG juices.

E-Liquid Frequently Asked Questions
What is the most popular e-liquid flavour in the UK?
Fruity flavours consistently rank as the most popular, with blends like Blue Razz Lemonade, Strawberry Ice, and Watermelon being top sellers. However, flavour is subjective, so the "best" one is the one you enjoy the most!
How long does a 10ml bottle of e-liquid last?
This depends heavily on your vape kit and how often you use it. For a low-power MTL pod kit, a 10ml bottle could last anywhere from 3 to 7 days. For a high-power sub-ohm device, it might only last a day or two.
Can e-liquid expire or go bad?
Yes, e-liquid has a shelf life, typically around two years from the date of manufacture. Over time, the flavour may weaken and the nicotine can degrade, sometimes causing the liquid to darken in colour. It's always best to use it before the expiry date printed on the bottle.
Is it safe to vape e-liquid?
Public Health England has stated that vaping is at least 95% less harmful than smoking cigarettes. The ingredients in UK-regulated e-liquids (PG, VG, flavourings, nicotine) are well-understood and considered safe for inhalation when vaporised.
What's the difference between e-liquid and nic salt?
Nic salt is a type of e-liquid. The main difference is the kind of nicotine used. "Standard" e-liquid uses freebase nicotine, while nic salt e-liquid uses a different formulation that provides a smoother throat hit at higher strengths.
Can I use any e-liquid in any vape?
No, it's very important to match your e-liquid to your device. Use High PG or 50/50 liquids (including nic salts) in low-power pod and MTL kits. Use High VG liquids (shortfills) in high-power sub-ohm and DTL kits.
