100ml Vape Juice
100ml vape juice is the workhorse format of UK sub ohm vaping. Every one of the 685 bottles in this collection is a shortfill, which means it holds 100ml of nicotine free flavoured base inside a 120ml bottle with the top 20ml deliberately left empty for two nicotine shots. Fill that gap and you finish with 120ml of ready to vape liquid at roughly 3mg per ml. Most bottles here sit between £7 and £11 before shots, which puts the finished cost comfortably under 10p per millilitre.
The size exists for a specific legal reason rather than a marketing one. UK regulations cap any nicotine containing e-liquid at 10ml per bottle, so the only lawful way to sell a large bottle is to sell it with no nicotine in it at all. Manufacturers settled on 100ml in a 120ml bottle because it takes exactly two standard 10ml shots and lands on the 3mg strength that low resistance coils are comfortable with. Once that convention stuck, almost every UK juice line built its flagship flavours around it.
What the number on the bottle actually means
A bottle labelled 100ml contains 100ml of liquid. The container itself is a 120ml unicorn style bottle. The 20ml of air at the top is not a short measure or a filling error. It is the space your nicotine is meant to occupy. Two bottles that both say 100ml hold the same volume of base whatever they look like on the shelf, because bottle moulds and shoulder shapes differ between manufacturers.
Many brands also print the finished strength on the label, usually 3mg, alongside wording such as two 10ml nic shots required. That figure assumes 18mg shots. Using 20mg shots puts you slightly above it.
Adding your nicotine shots
The two shot routine
Take the cap off, lever the childproof insert out with the back of a teaspoon, empty both 10ml shots in, refit the insert and cap, then shake firmly for thirty seconds. The liquid goes cloudy while air is suspended in it. That clears on its own within a few minutes standing on the worktop. There is no equipment involved and nothing to measure.
Where the strength ends up
Two 18mg shots put 360mg of nicotine into 120ml of finished liquid, which is exactly 3mg per ml. Two 20mg shots put 400mg into 120ml, which works out at 3.33mg per ml. Both are ordinary sub ohm strengths. Neither feels harsh through a low resistance mesh coil, which is precisely why the format settled where it did.
Is 100ml the right size for you
Sub ohm and direct to lung vapers
If you run a mesh coil below 0.3 ohm at 40W or more you can get through 8ml to 12ml on a heavy day. At that rate a finished 120ml bottle is roughly a fortnight of vaping, which makes buying in 10ml bottles both expensive and tedious. This is the audience the 100ml format was built for.
Pod and mouth to lung vapers
A 1.0 ohm pod at 12W might use 3ml a day. A 120ml bottle would then last six weeks or more, which is a long time to be married to one flavour. There is also a ratio problem. Most 100ml shortfills are mixed at 70/30 VG to PG, which is too thick for the tight cotton channels in a mouth to lung pod. Pod vapers usually do better with a 40ml or 50ml pod fill base or with 10ml nic salts.
Cost per millilitre
The maths is worth doing once and then forgetting about. A 100ml shortfill at around £9 plus two nicotine shots produces 120ml of finished liquid. Buying that same 120ml as twelve individual 10ml bottles at normal UK prices costs several times as much. A 50ml shortfill plus one shot gives 60ml and sits between the two on a per millilitre basis, because the bottle, cap and label cost about the same to produce whether they hold 60ml or 120ml.
The catch is strength. A shortfill of this size can only reach about 3mg. If you need 10mg or 20mg you are in nic salt territory and none of this saving applies to you.
Choosing a flavour you will still enjoy in three weeks
Buying 120ml of anything is a commitment. Vaper's tongue is a genuine effect too. Strong or very sweet profiles fatigue the palate faster than simple ones do. Single fruits, light iced blends and menthols tend to stay drinkable right across a bottle. Rich custards, thick bakery flavours and heavy candy mixes are more likely to wear thin somewhere around the halfway mark. A sensible approach is one 100ml as your everyday all day vape plus a smaller bottle of something louder to rotate through when you want a change.
Sweetener content matters more at this volume than at any other. Heavily sucralosed liquids caramelise onto the coil and can cost you a fresh coil every four or five days, which quietly eats the saving you made on the juice.
VG ratios across the 100ml range
The great majority of 100ml shortfills are 70/30 VG to PG. That thickness is deliberate. It resists weeping through the large wicking ports on sub ohm coils while producing the dense vapour direct to lung vapers want. A few lines run at 80/20 for more vapour at the cost of a little flavour clarity. A 50/50 mix in this bottle size is unusual and will normally be stated plainly on the label.
Match the ratio to the coil rather than to the brand name. Below 1.0 ohm means high VG. Above 1.0 ohm means 50/50.
Handling, decanting and storage
A 120ml bottle is not a practical thing to carry around. Decant what you need into a 10ml or 30ml squeeze bottle for the day and leave the large bottle at home, standing upright in a cupboard away from sunlight and heat. Nicotine oxidises when it meets air, so every time the big bottle is opened the clock ticks a little faster. Keeping it shut and cool preserves both the colour and the top notes.
Label anything you decant. Unmarked bottles of e-liquid should be kept well out of reach of children and pets, since a childproof cap only protects the bottle it was supplied on.
What is stocked in the 100ml range
The 685 bottles here run across the full spread of UK flavour families. Iced and menthol fruits form the largest group by some way. Berry and tropical blends follow closely behind. Sweet shop, cola and energy drink profiles are well represented. Bakery, custard and doughnut flavours cover the dessert end of the range. Brands appearing in the 100ml selection include Doozy, Drifter, Bar Series, Just Juice, ImpJar, Vortex, Big Bold, Future Juice, Bar Vape and Bear State Vapor.
The legal position on large bottles
Selling 100ml of nicotine e-liquid in a single bottle is not permitted in the UK. That is the entire reason these bottles are nicotine free. The shots are separate 10ml products, notified to the Medicines and Healthcare products Regulatory Agency and capped at 20mg per ml. None of this is a loophole. It is how the Tobacco and Related Products Regulations were designed to operate. All vaping products are sold to over 18s only and every order is age verified before it is dispatched.

Your 100ml vape juice questions
How much e-liquid do I actually get from a 100ml shortfill?
You get 120ml once both nicotine shots are mixed in. The bottle holds 100ml of nicotine free base with 20ml of headroom left for two 10ml shots. If you prefer to vape the base at 0mg without adding anything, you simply get the 100ml as sold.
How many nic shots does a 100ml shortfill take?
Two 10ml shots. The 120ml bottle is designed around that number. Adding only one shot leaves you at roughly 1.6mg per ml, which most vapers find too weak to satisfy. Adding three will overflow the bottle and even if you decant first it only takes you to about 4.5mg.
Why is the bottle 120ml when the label says 100ml?
Because the missing 20ml is where your nicotine goes. UK law caps nicotine e-liquid at 10ml per bottle, so any large bottle has to be sold nicotine free. Manufacturers use a 120ml bottle filled to 100ml so that exactly two standard shots complete it. The gap is intentional rather than a short measure.
Can I make a 100ml shortfill stronger than 3mg?
Not in the original bottle. Two 18mg shots land at 3mg per ml and two 20mg shots at about 3.3mg per ml. Going higher means decanting part of the base into a second bottle and shotting each portion separately, which becomes more trouble than it is worth. Anyone vaping at 10mg or 20mg should stay with 10ml nic salts.
How long does 120ml of e-liquid last?
That depends on the device far more than on the vaper. A sub ohm mesh coil running at 40W or more can use 8ml to 12ml a day, which works out at roughly two weeks. A mouth to lung pod at 12W might use 3ml a day, stretching the same bottle past six weeks. Measure your daily usage once and the answer follows.
Can I use a 100ml shortfill in a pod kit?
Only if the pod takes a coil rated below 1.0 ohm. Most 100ml shortfills are 70/30 VG to PG and that thickness will not wick through the tight cotton channels used in high resistance pods, which leads to dry hits and a burnt coil. For a standard mouth to lung pod, choose a 40ml or 50ml pod fill base or a 10ml nic salt.
Does e-liquid go off?
It does not spoil the way food does, although it does change. Nicotine oxidises on contact with air, which darkens the liquid and softens the flavour over a period of months. Flavourings themselves fade with light and heat. Stored upright, capped and in a dark cupboard, a shortfill will comfortably outlast the time it takes you to vape it.
Is a 100ml shortfill better value than 10ml bottles?
On price per millilitre it is not a close contest. One 100ml shortfill plus two shots produces 120ml of finished liquid. The same volume bought as twelve separate 10ml bottles costs a great deal more. The saving only counts if 3mg suits you though, since that is the ceiling this format can reach.
Can I mix two different 100ml shortfills together?
You can, though you will need an empty bottle to do it in because neither bottle has spare room. Mixing two similar profiles such as two fruits usually works well. Dropping a dessert into a menthol usually does not. Test a small amount in a 10ml bottle before committing 200ml of juice to the experiment.
Do I need to be 18 to buy 100ml shortfills?
Yes. Vaping products are sold to over 18s only in the UK, nicotine free shortfills included. Every order is age verified before it is dispatched and identification may be requested. Free UK delivery applies on orders over £20 and the team can be reached on 07827 210361 between 8.30am and 4.00pm.
