What is E-Liquid?
This thin, colourless liquid has a faint sweetness and is much lighter than VG, giving vape juice a smoother consistency. PG delivers a noticeable throat hit, closely resembling the feel of smoking tobacco, which is why it’s often preferred by those looking for a stronger, cigarette-like sensation. It also helps keep e-liquid versatile, making it suitable for use in everything from simple pod kits to more advanced vape devices.
Naturally derived from vegetable oils, it’s odourless with a slight sweetness, helping to soften the throat hit while carrying flavour gently. VG is most commonly used in high-VG e-liquids, making it a favourite for direct-to-lung (DTL) vapers who enjoy bigger clouds and a smoother inhale.
Flavourings give e-liquids their unique taste and are made from a blend of food-grade ingredients, both natural and artificial. These flavour concentrates are usually mixed with PG, which helps carry and evenly spread the flavour through the vape juice.
Nicotine is optional in e-liquids and comes in two forms: nicotine salts and freebase nicotine. Nic salts give a smoother throat hit and faster absorption, while freebase offers a stronger hit, often at lower strengths. UK law caps nicotine at 20mg. Vapers can choose from high strengths for switching, lower strengths for lighter use, or 0mg for flavour-only vaping.
Occasionally added in small amounts to thin thicker vape juices, making them easier for certain devices to use.
Understanding PG and VG Ratios
High PG e-liquids use a greater proportion of Propylene Glycol (PG), giving a stronger throat hit and clearer flavour. Their thinner consistency makes them ideal for pod kit devices, vape pens, and other MTL (mouth-to-lung) devices. High PG blends deliver a cigarette-like sensation with crisp, satisfying taste.
High VG e-liquids contain a higher ratio of Vegetable Glycerine (VG) compared to Propylene Glycol (PG), making them ideal for vapers who prefer a smoother inhale. Flavour can be slightly softer compared to High PG blends; the trade-off is a richer, smoother experience with larger vapour production.
50/50 e-liquids combine equal parts Propylene Glycol (PG) and Vegetable Glycerine (VG), offering the best of both worlds. This balance provides a smooth vapour with a satisfying throat hit, making them versatile for different vaping styles. Popular with both beginners and experienced users, 50/50 blends are a reliable everyday e-liquid choice.
Freebase vs Nicotine Salts
Freebase is the traditional style of e-liquid, offering a sharper throat hit and a slower release of nicotine. This makes it popular with vapers who want a sensation closer to smoking. Freebase e-liquids are most often found in 10ml bottles with High PG or 50/50 blends, which are ideal for MTL (mouth-to-lung) devices like pod kits and vape pens. Some low-strength Freebase shortfills in High VG exist, but they are much less common.
Nic salts are designed to deliver nicotine to the body more quickly with a smoother inhale, even at higher strengths. They’re perfect for MTL pod kits and are especially popular with those switching from smoking or disposable vapes who want quick craving satisfaction without harshness. Like Freebase, Nic Salts are usually available in High PG or 50/50 blends, but you can also find low-strength nic salt shortfills in High VG for use in sub-ohm kits.
Most Freebase and Nic Salt e-liquids come in High PG or 50/50 blends designed for everyday MTL vaping. High VG versions do exist, but they are lower strength and intended for sub-ohm DTL devices where big clouds and smoother nicotine delivery are preferred.
Which E-Liquid Should I Use With My Vape Kit?
These smaller, pod or pen style devices use coils with higher resistance (0.8–1.4 ohms), meaning they produce less vapour but a stronger throat hit. They work best with High PG, 50/50 e-liquids or nicotine salts, giving a smooth, satisfying draw that feels closer to smoking.
Sub-ohm kits use lower resistance coils, which create bigger clouds and a smoother inhale at higher power. They’re designed for High VG or shortfill e-liquids, making them perfect for cloud chasers and vapers who want maximum vapour.
Flexible vape kits (RDL, 0.4Ω–0.6Ω) use changeable coils, letting you switch between setups for either a stronger throat hit or bigger clouds. Offering a restricted direct-lung draw, they balance flavour, vapour, and satisfaction, working well with both 50/50 e-liquids and High VG juices.
Types of E-Liquid
Nic salts are designed for MTL (mouth-to-lung) kits like pod kit devices and vape pens. They provide a smooth throat hit even at higher nicotine strengths, making them ideal for new vapers or anyone switching from smoking.
High PG vape juice delivers sharper flavour and a stronger throat hit, making it a great option for MTL devices that replicate the feel of smoking. These are usually found in 10ml bottles and are popular with ex-smokers looking for a cigarette-like experience.
Made with a balanced mix of PG and VG, 50/50 e-liquids give you the best of both worlds: a satisfying throat hit with decent vapour production. They work perfectly in starter kits, pod kits, and vape pens. Available in both 10ml bottles and shortfills, they’re a versatile everyday choice.
High VG e-liquids are thicker and smoother, producing large clouds of vapour. They’re best suited to sub-ohm kits and DTL (direct-to-lung) vaping, where you inhale straight into the lungs. Often sold as shortfills (50ml or 100ml bottles), they’re a favourite among cloud chasers.
Shortfills are larger bottles of nicotine-free e-liquid, usually High VG for DTL sub-ohm vape kits, though some come in 50/50 blends for versatile kits. Because UK TPD regulations restrict pre-mixed nicotine e-liquids to 10ml bottles, shortfills and nic shots give vapers a simple, cost-effective way to enjoy bigger bottles of vape juice while choosing their preferred nicotine level. Popular with DTL
Freebase nicotine is the traditional form of vape juice, offering a stronger throat hit and slower nicotine release. Best in 10ml bottles, freebase liquids are often used in MTL devices with High PG or 50/50 blends, making them popular with vapers seeking a cigarette-like feel.
What Flavour of E-Liquid Is Right for Me?
Rich, earthy flavours that echo the taste of traditional tobacco, with smooth or robust variations.
Bright, juicy blends ranging from familiar favourites like Strawberry to exotic tropical medleys.
Fresh, cooling flavours that range from soft mint to punchy, ice-cold menthol profiles.
Inspired by classic puddings and sweet dishes, these flavours include notes like vanilla, custard, and pastry.

What Are Shortfill E-Liquids?
Due to the EU’s Tobacco Products Directive in 2016, e-liquids that contain nicotine can only be sold in units of 10ml eliquid bottles. At Vapestore, we ensure that all our 10ml bottles are of the highest quality and are available at the most acecessible, affordable prices, giving you the freedom to explore and experiment with flavours until you find the perfect taste profiles for you.
Shortfill e-liquids offer a simple solution that saves money, while also reducing wasted packaging. Shortfill bottles contain regular e-liquid, but the liquid is completely nicotine free. They usually come in bottles containing 50ml or 100ml of liquid, with enough room in the bottle to add a Nicotine Shot that will add 18mg nicotine strength to your e cig liquid. For example, if you have a 60ml shortfill bottle with 50ml of e-liquid in it, you can add a 10ml nicotine shot at 18mg strength. This will achieve 60ml of e-liquid at 3mg strength. For more information on calculating shortfill strengths, check out our handy guide here.
We have a great range of shortfill e-liquid deals, and many of them come with a free nicotine shot for even better value. Shortfills usually come in high VG formula and work perfectly in sub ohm devices.
