Whether you're brand new to vaping or you've been doing it for years, there's always something new to learn – especially when it comes to e-liquids. One term you've probably come across is shortfill. It sounds a bit technical, but it's actually a brilliant solution for anyone looking to tailor their nicotine levels while enjoying more of their favourite flavours.

In this guide, we’ll walk you through what shortfill e-liquids are, why so many vapers swear by them, and how you can start using them with ease. By the end, you’ll feel more confident about customising your vape and getting the most out of every bottle.

So, What Exactly Is a Shortfill?

Shortfill e-liquids are large bottles of vape juice that come without nicotine. They’re usually filled slightly below the bottle’s full capacity – hence the name “shortfill.” This little bit of empty space isn’t a mistake. It’s there so you can add a nicotine shot (also called a “nic shot”) if you want.

This format came about due to regulations like the EU’s Tobacco Products Directive, which limits the sale of nicotine-containing e-liquids to 10ml bottles. By keeping the nicotine separate, shortfills let you enjoy bigger bottles – like 50ml or 100ml – without breaking the rules. It also gives you control over how much (or how little) nicotine goes into your vape.

Why Shortfills Are a Game-Changer

For many vapers, shortfills hit the sweet spot between convenience, choice and personalisation. You get more liquid in one bottle, which is often more cost-effective than buying several smaller ones. And because there’s no nicotine added by default, you can decide how strong you want your vape to be – or skip nicotine altogether.

Another bonus? Flavour variety. Many of the most exciting and complex e-liquid flavours are offered in shortfill form. That means you’re not limited to just a handful of options—you’ve got a whole menu to choose from.

How to Use Shortfill E-Liquids

If you’re new to shortfills, don’t worry—the process is straightforward. All you need is your shortfill bottle and the right amount of nic shots, usually in 10ml bottles at 18mg strength.

To get started, open the shortfill by removing the cap and nozzle. Then, squeeze in the nic shot. For a standard 50ml shortfill, adding one 10ml shot at 18mg will give you a final nicotine strength of around 3mg once everything's mixed together. If you’re using a 100ml shortfill, you’d typically add two nic shots to reach that same 3mg level.

Once your nic shot is in, pop the nozzle and cap back on and give the bottle a good shake – about a minute should do the trick. This helps the nicotine blend evenly with the rest of the liquid. While you can technically vape it straight away, letting it sit for a few hours (or even overnight) can really help the flavours come together.

Which Nicotine Shot Should You Use?

There’s more than one type of nic shot out there, and choosing the right one can make a big difference to your vaping experience.

Freebase nicotine shots offer a stronger throat hit, which can feel a bit more like smoking – ideal if you're looking to replicate that sensation. Nicotine salt shots, on the other hand, are smoother on the inhale and deliver nicotine more quickly. They’re a great choice if you’re aiming for a higher strength without the harshness.

Also, keep an eye on the VG/PG ratio of your nic shot. Matching it to your shortfill ensures consistency in vapour production and throat hit. High VG blends produce thicker clouds and are better suited to sub-ohm devices, while 50/50 mixes work well with pod systems and mouth-to-lung setups.

Got Questions? You’re Not Alone

Shortfills might seem a bit fiddly at first, but once you get the hang of it, they become second nature. One common question we hear is whether you have to add nicotine. The answer is no – if you’re happy vaping without it, you can enjoy shortfills just as they are.

Another is how long you should steep your e-liquid after adding a nic shot. While it’s fine to vape it straight away, giving it a few hours to settle can bring out deeper, richer flavours. Think of it like letting a good cup of tea brew – worth the wait.

And if you’re wondering whether shortfills work with your device, the answer depends on the VG/PG blend. High VG shortfills are best paired with sub-ohm devices, which can handle thicker liquids. If you're using a smaller pod system or mouth-to-lung kit, look for 50/50 blends for a smoother experience.
