Eliquid: What Does Short Fill Mean?

Someone asked me a question on Facebook the other day —

What does short fill mean?”

What Does Short Fill Mean? 2

It’s a good question. I had to Google it a while back, and I figured other people would probably ask the same question. So … why not write a blog all about it?

Smart, right? I know. I’m taking a bow as we speak.

What Are Short Fill Eliquids?

Short fill eliquids are eliquid bottles that are not quite full. No, the company hasn’t ripped you off a bit. They’re meant to be like that. It was someone’s genius idea to get around the TPD regulations and those ridiculous (and totally NOT eco-friendly) 10ml bottles. You get a big bottle that isn’t quite full with eliquid and then add your own nicotine shots.

Short fill eliquid bottles come in a number of sizes, with a number of different types of eliquid, and can be made up to your desired strength with the right nicotine shots. These are also known as nic shots, nicotine boosts or boosters, and a hundred and one other names that I will never be able to keep on top of.

Here are some short fill liquids that I’ve recently received and mixed together:

Drake’s Eliquid Kentucky

What Does Short Fill Mean? 5

You get 50ml of 0mg liquid in a 60ml bottle. Add 1 x 18mg nicotine shot (10ml) 50/50 VG/PG to give you 60ml of 3mg 50/50 juice.

(You kept up with all that, right?)

Decadent Vapours Lemon Puff

  • 60/40 VG/PG (once concentrate + nicotine has been added)
  • 3mg
  • Bloody lovely
  • Sub ohm juice

What Does Short Fill Mean? 2

You get 40ml of 0mg liquid in a 60ml bottle. Add 1 x 18mg Nicotine Boost PLUS 10ml bottle of ‘diluent’ to get 3mg.

I had to Google what diluent was as I’d never heard of it before.

100 Large Zest Pest 

  • 70/30 VG/PG
  • 3mg
  • Deliciously Zesty
  • Sub ohm juice

What Does Short Fill Mean? 7

You get 100ml of 0mg liquid in a 120ml bottle. Add 2 x 18mg nicotine shot (10ml) 70/30 VG/PG to give you 120ml of 3mg 70/30 juice. 

In Short …

3mg Finished Product

If you have 50ml of 0mg liquid, add ONE 10ml bottle of 18mg nicotine shot to make 60ml of 3mg. I had to do this with The Rochford Project’s eliquids, like this Lemon Lush delight:

If you have 100ml of 0mg liquid, add TWO 10ml bottles of 18mg nicotine shots to make 120ml of 3mg.

Things CAN get a little complicated because you can also buy different nicotine strength shots or boosters. If you were to get 80ml of 0mg liquid, for example, you would need TWO bottles of 15mg nicotine shots to make 100ml of 3mg. Confused yet? Don’t worry, me too. The good news is that many of the websites that you buy from will include details of how to make the desired eliquid strength using nic shots.

With 100 Large eliquid bottles, there are peel-away labels that give you step-by-step instructions too.

6mg Finished Product

I’m going to be super honest about this … I’ve not mixed anything higher than 3mg unless it was by accident and I didn’t realise. I have done some research, however, and this is what I found:

If you have 50ml of 0mg liquid, add TWO bottles of 18mg nicotine shots to make 70ml of 6mg.

If you have 100ml of 0mg liquid, add FOUR bottles of 18mg nicotine shots to make 140ml of 6mg.

> The more nicotine shots you add, the more diluted the juice flavour will be unless you opt for flavoured nicotine shots or boosters. I’m pretty sure I had some Fruizee eliquid bottles that had flavoured shots. I’m still trying to work those out … bear with me.

> If you buy a 60ml capacity short fill bottle that contains 50ml of eliquid but you want to add TWO 18mg 10ml nicotine shots, you won’t have enough room in the bottle.

> There are LOADS of nicotine shot/DIY ejuice calculators online if you want to look at 6mg + DIY juices or short fills. I don’t understand how to use most of them, but I did come across one that I could easily use, from (I’m also pretty sure that I found that website through ecigclick too. They’re my go-to site when I don’t understand something.)

THERE ARE DIFFERENT VG/PG NICOTINE SHOTS. Make sure that you buy and add the appropriate VG/PG ratio when you’re buying nicotine shots/boosters. My mouth-to-lung Drake’s Eliquid Kentucky was a 50/50 juice, so needed 50/50 nicotine shots. A different flavour in the same Drake’s Eliquid package — Burley — was a 70/30 juice (sub ohm), so needed 70/30 nicotine shots. (I’ve screwed this up a few times because I didn’t read the labels properly. Dumbass.)

All of the nicotine shots below are different – they have different VG/PG ratios. Check that you’re buying the right one before you make the same mistakes that I did. (Click to see them full size.)

The world of short fill and DIY eliquid is a little confusing, but I think I’m slowly starting to get my head around it … Like, super slowly.

Do Short Fill Eliquids Come With Nicotine Shots Included?

Great question, right? I can’t tell you the number of times I’ve had to ask whether or not the liquid actually comes with nic shots. Firstly, the information on the website isn’t always obvious, I think. Secondly, I MOSTLY get send review packages of 0mg liquids and their accompanying nicotine shots, without any information on whether or not the kits come with them. Then I need to do the embarrassing question asking that makes me look stupid.

“Oh, hey, yeah, I have a question. I know I received nicotine shots, but do the 0mg liquid kits actually come with them? Or would customers need to buy those separately?”

Six Licks eliquids DO NOT come with nicotine shots. You need to buy those separately.

Decadent Vapours come with both the nicotine shots and ‘diluent’ in the box. You DO NOT need to buy these separately. I don’t think that’s immediately obvious from the website, though. I actually messaged Mr. Decadent Vapours to find out.

The Rochford Project’s eliquid kits have included shots/boosters too — the nicotine shots come in the box and you DO NOT need to buy them separately.

You know what I say? If in doubt, ask. Don’t just risk it. There is NOTHING worse than having a truckload of new eliquids turn up that you can’t use yet because they didn’t come with nic shots and you don’t have any spare/matching bottles in the house.


I hope I’ve answered your questions as far as short fill eliquids are concerned, but if you have any more, please don’t hesitate to let me know. You know how much I love to talk … you’re just giving me an excuse to tap up a brand new blog post!
