Getting your e-liquid right makes the difference between a vape you reach for all day and one you abandon in a drawer. The format, nicotine strength, and PG/VG ratio all work together. If one element is wrong, the entire experience suffers, regardless of how good the flavour is.

This guide covers everything you need to choose with confidence. It explains what each format does, which nicotine strength suits your situation, and how to approach flavour selection without guessing.

What E-Liquid Is and What It Contains

E-liquid, also known as vape juice, is the liquid your device heats to produce vapour. When the coil activates, it warms the liquid and turns it into flavoured vapour that you inhale. Importantly, there is no combustion and no smoke involved.

Most e-liquids contain four key ingredients: propylene glycol (PG), vegetable glycerin (VG), food-grade flavourings, and optional nicotine. The balance between PG and VG plays a major role in how your vape feels and performs.

Propylene Glycol (PG)

PG is thinner and carries flavour effectively. It provides a stronger throat hit and sharper taste. Therefore, higher PG feels closer to smoking.

Vegetable Glycerin (VG)

On the other hand, VG is thicker and slightly sweet. It produces larger vapour clouds and delivers a smoother inhale. Higher VG creates a softer and more cloud-focused experience.

The Different E-Liquid Formats and What They Do

1. 10ml E-Liquids (Freebase Nicotine)
10ml e-liquids are the standard TPD-compliant bottles available across UK vape shops. They come in strengths from 3mg to 18mg and work well with starter kits, pen-style vapes, and pod systems. The throat hit is more noticeable, especially at higher strengths. For many ex-smokers, this provides a familiar sensation. However, regular use can become costly over time, which is why many users eventually move toward shortfills.
2. Nicotine Salts (Nic Salts)
Nicotine salts transformed vaping for many ex-smokers. Because of their formulation, they allow users to vape at 10mg or 20mg without the harsh throat irritation associated with freebase nicotine. Additionally, nicotine absorption is faster, which helps satisfy cravings more quickly. Since they are typically balanced at 50/50 PG/VG, they work perfectly with pod systems and MTL devices. If you are switching from cigarettes, nic salts are often the most effective starting point.
3. Bar Salts (Disposable-Inspired)
Since the UK disposable vape ban came into effect, bar salts have rapidly grown in popularity. They are designed to replicate the bold and sweet flavours found in popular disposable vapes. For example, if you enjoy flavours like Blue Razz Lemonade or Watermelon Ice, bar salts deliver a similar experience in refillable devices. Their flavour concentration is higher, which creates a strong and immediate taste. However, it is worth noting that this intensity can reduce coil lifespan slightly. Therefore, if coils wear out quickly, this is often the reason.
4. Shortfills (50ml and 100ml)
Shortfills are larger bottles, typically available in 50ml Shortfill or 100ml shortfill sizes, and are sold without nicotine. This allows them to bypass TPD bottle restrictions. Space is left in the bottle so users can add nicotine shots. For example, adding one 10ml 18mg nicotine shot to a 50ml shortfill results in approximately 3mg strength across 60ml. These liquids are usually high VG, making them ideal for sub-ohm and DTL vaping. As a result, they produce more vapour and often deliver a fuller flavour profile. They are also more cost-effective for regular users.
5. 50/50 E-Liquids
A 50/50 e-liquid blend offers a balanced experience. It works reliably across most devices, including starter kits and pod systems. The flavour remains clear, while the throat hit is noticeable but not overwhelming. Therefore, for beginners, a 50/50 e-liquid at 10mg or 20mg is often the safest and most versatile choice.
6. Nicotine Shots
Nicotine shots are small 10ml bottles of unflavoured nicotine designed to be added to shortfills. Most are available in 18mg strength. In addition, some options include salt nicotine or cooling effects, which can slightly alter the final vaping experience. This is useful for users who prefer to customise their setup.

Nicotine Strength: Choosing the Right Level

Choosing the correct nicotine strength is essential. If the strength is too low, cravings will persist. If it is too high, the experience may feel unpleasant.

User Profile Recommended Strength Recommended Format
Heavy smoker (20+ a day)20mg nic saltNic salt / bar salt
Moderate smoker (10–20 a day)10–20mg nic salt or 12mg freebaseNic salt or 50/50
Light smoker (under 10 a day)6–10mg nic salt or 6mg freebase50/50 or nic salt
Vaper reducing nicotine3–6mg freebase50/50 or shortfill
Cloud chaser / sub-ohm3mg freebaseHigh-VG shortfill

Importantly, nic salts remain smooth even at higher strengths, whereas freebase nicotine can feel harsh above 6mg for many users.

Flavour: Choosing What Actually Works

Flavour selection is more detailed than it first appears. While categories help, the specific profile matters just as much. To avoid flavour fatigue, it is best to rotate between two or three flavours regularly.

Tobacco
Often the starting point for new users because they feel familiar. However, over time, many users transition toward fruit or menthol options.
Menthol and Ice
Popular, particularly for those who previously smoked menthol cigarettes. They provide a clean and refreshing inhale.
Fruit Flavours
Dominate the UK market. They are enjoyable for long-term use and reduce flavour fatigue.
Dessert
Flavours such as custard or vanilla are richer and better suited for occasional use.
Drink-Inspired
Cola or lemonade offer a balance between fruit and sweetness. Easy to vape throughout the day.

Which Format Suits Your Vaping Style?

Your device determines which e-liquid will perform best. Using the wrong liquid type can result in poor performance or burnt coils. Therefore, always match your e-liquid to your device.

MTL Vaping

Closest to smoking and works best with 50/50 liquids and nic salts.

RDL Vaping

Offers a balance and supports a wider range of liquids.

DTL Vaping

Produces large clouds and requires high-VG shortfills and sub-ohm coils.

Our E-Liquid Brands: What We Carry and Why

At AJ Super Store, we stock brands that consistently perform well in the UK market. These include Hayati, Elux, Dinner Lady, Riot Squad, Nasty Juice, and Crystal Prime.

Each brand offers something unique. For example, Dinner Lady is known for dessert flavours, while Riot Squad focuses on bold combinations. Nasty Juice excels in tropical blends, and Elux delivers strong disposable-style flavours.

Safety, Compliance and UK Regulations

All e-liquids sold in the UK must comply with the Tobacco and Related Products Regulations 2016. This means nicotine-containing liquids are limited to 10ml bottles with a maximum strength of 20mg.

Additionally, products must be registered with the MHRA before sale. At AJ Super Store, all products meet these requirements.

Furthermore, UK law requires age verification, and sales to anyone under 18 are strictly prohibited.

What to Pair With Your E-Liquid

Choosing the right device and coil is essential for the best experience. Higher resistance coils work best with 50/50 and nic salts, while sub-ohm coils are designed for high-VG liquids.

If you are using shortfills, nicotine shots are a useful addition. Additionally, selecting the right pod kit can significantly improve overall performance.
