The Complete Shortfill E-Liquid Guide (2026)
If you've browsed vape products, you've seen shortfill e-liquids. This shortfill e-liquid guide explains their popularity. They are popular among experienced vapers. They are also popular for sub-ohm vape kit users. But what is a shortfill? Why isn't the bottle full? How do you add nicotine?
This guide answers common questions about shortfill vape juice. Buying your first bottle? Or seeking the best flavour? You'll find everything you need here.
What Is a Shortfill E-Liquid?
A shortfill e-liquid is a nicotine-free vape juice supplied in a bottle that has extra space left at the top. This empty space is designed so you can add a nicotine shot if you want nicotine in your vape.
For example:
- 60ml bottle containing 50ml of e-liquid
- 120ml bottle containing 100ml of e-liquid
The remaining space allows you to customise the nicotine strength without affecting the flavour too much.
Shortfills became popular because UK regulations limit nicotine-containing e-liquids to 10ml bottles. By selling larger nicotine-free bottles, manufacturers give vapers more flexibility while remaining compliant with UK regulations.
Why Choose a Shortfill E-Liquid?
Shortfills offer several advantages over traditional 10ml bottles.
Better Value
Buying one large bottle is usually more cost-effective than purchasing multiple smaller bottles.
More Flavour Options
Manufacturers often release premium flavours as shortfills first. This gives you more options. Choose from fruity, dessert, and menthol blends. Drink-inspired and tobacco blends are also available.
Custom Nicotine Strength
Not everyone wants the same nicotine level. With shortfills, you decide whether to vape nicotine-free or add one or more nicotine shots.
Ideal for Cloud Chasing
Most shortfills use high VG ratios such as 70VG/30PG, making them perfect for producing dense clouds and smooth flavour.
Less Plastic Waste
Using one large bottle instead of several smaller ones can reduce packaging waste.
How to Add a Nicotine Shot
Adding a nicotine shot is quick and easy.
Step 1 : Remove the bottle cap and nozzle carefully.
Step 2 : Open your nicotine shot.
Step 3 : Pour the nicotine shot into the shortfill bottle.
Step 4 : Replace the nozzle and cap tightly.
Step 5 : Shake the bottle for at least one minute until everything is mixed.
Step 6 : Leave the bottle to settle for a few minutes before vaping.
Nicotine Mixing Guide
| Shortfill Size | Nicotine Shots | Final Strength |
| 50ml | 1 x 10ml 18mg | Approximately 3mg |
| 100ml | 2 x 10ml 18mg | Approximately 3mg |
| 100ml | 1 x 10ml 18mg | Approximately 1.5mg |
Always follow the manufacturer's recommendations when mixing nicotine.
Common Mistakes to Avoid

Avoid these common errors:
- Forgetting to shake the bottle after mixing.
