A large-format bottle of flavoured e-liquid containing no nicotine, packaged in a 120ml bottle with 20ml of headroom for you to add two nicotine shots.
Same principle as a 50ml shortfill, just scaled up. The bottle arrives with space at the top. You pour in two 10ml nic shots, replace the cap, shake until the liquid is fully blended, and the result is 120ml of mixed nicotine e-liquid ready to go.
Why 120ml and Not 100ml?
The bottle has to be bigger than the liquid inside it. A 100ml shortfill needs 20ml of extra room (two nic shots at 10ml each), so the bottle is 120ml. That gap is the whole point of the shortfill concept. Without it, there is nowhere for the nicotine to go.
Who Buys 100ml Over 50ml?
Vapers who have found their flavour. Simple as that.
A 50ml shortfill gives you 60ml after mixing. Enough for a week, maybe ten days at moderate sub-ohm use. Manageable if you are still figuring out what you like or if you rotate flavours frequently.
A 100ml gives you 120ml. That could last two to three weeks of steady vaping. If you are committed to a flavour and do not want to reorder constantly, the bigger bottle saves money and hassle. But if you get bored halfway through, you are stuck with 60ml of something you no longer fancy. Know yourself before you buy big.
Best 100ml Shortfill Brands in the UK
Here are some of the best shortfill brands available for sale in the UK.
Dinner Lady
British-made and one of the few UK brands that has built genuine international recognition. Lemon Tart is the headline, but the broader dessert and tobacco range holds up across the board. Consistent batch quality at 100ml, which matters more than people realise. A bad 10ml bottle is a minor annoyance. A bad 100ml is a genuine waste.
Vampire Vape
Heisenberg at 100ml is one of the highest-volume single SKUs in the UK shortfill market. The blend of fruit and menthol has not changed because it does not need to. Pinkman runs second. The range beyond those two covers berry, bubblegum, and a handful of tobacco options.
Doozy
Heavy on dessert and candy. The Seriously range pushed Doozy into bigger bottle formats and the flavour profiles carry well at 100ml. Expect sweetness. If that is what you want, Doozy delivers.
Just Juice
Tropical fruit with genuine definition. Mango and Passionfruit, Wild Berries, Blood Orange Citrus Guava. The flavours hold their clarity across a large bottle without going flat by the last few fills. That consistency is harder to achieve than it sounds.
Riot Squad
Punchy and slightly sour. The fruit range leans aggressive rather than soft. Blue Burst and Pink Grenade are the volume sellers. Good for vapers who find standard fruit blends too tame.
Nasty Juice ModMate
Malaysian formulation, and it shows in the layering. Cushman (mango) is the anchor flavour. The rest of the range runs deeper than a typical UK shortfill brand, with profiles that develop as you vape rather than hitting one note and staying there.
How Much Do 100ml Shortfills Cost Compared to 10ml Bottles?
12 individual 10ml bottles at £3 to £5 each = £36 to £60 for 120ml
1 x 100ml shortfill + 2 nic shots = roughly £10 to £18 for 120ml
Even at multi-buy pricing on the 10ml bottles, the 100ml shortfill wins comfortably. The gap narrows a bit with three-for or five-for deals on nic salts, but shortfills still come out cheaper per ml in almost every comparison.
But here’s something that you need to know about the nicotine strength:
• 100ml shortfills max out at about 3mg nicotine with two standard nic shots. You cannot reach 10mg or 20mg. If you need higher strength, 10ml nic salts are the only option.
• 10ml bottles come pre-mixed, require no effort, and are available up to 20mg nic salt. Convenience and strength range are the trade-off for the higher per-ml cost.
So the choice depends on two things: what strength you vape and how much effort you are willing to put in. If 3mg freebase through a sub-ohm tank is your setup, 100ml shortfills save you a noticeable amount of money every month.
What Nicotine Strength Does a 100ml Shortfill Give?
A 100ml shortfill contains 0mg e-liquid with enough bottle space for nic shots. The final strength depends on how many shots you add and whether they contain 18mg or 20mg of nicotine per ml.
Two Nic Shots (Standard)
Two 10ml nic shots at 18mg/ml into a 100ml shortfill = 120ml at 3mg/ml. The standard combination. Two shots, one bottle, done. This is how most sub-ohm vapers in the UK mix their liquid.
One Nic Shot (Lower Strength)
One nic shot into a 100ml shortfill = 110ml at roughly 1.6mg/ml. Too low for most vapers, but an option if you are actively stepping down from 3mg and want something barely there.
No Nic Shot
The liquid is 0mg as sold. Completely vapeable straight out of the bottle. Some vapers have quit nicotine entirely and just enjoy the flavour and the habit. The shortfill format works for them too.
With 20mg Nic Shots Instead of 18mg
Two 20mg shots into a 100ml shortfill = 120ml at roughly 3.3mg. Marginally stronger than the 18mg calculation. Most vapers will not notice the difference. Some prefer the slight bump.
How to Mix a 100ml Shortfill
Same idea as mixing a 50ml, but with two shots instead of one. Takes under a minute.
- Open the bottle. Unscrew the childproof cap. Remove the squeeze nozzle if there is one. The opening needs to be wide enough for the nic shot liquid to pour in cleanly.
- Add the first nic shot. Squeeze every drop from the first 10ml nic shot into the shortfill bottle. Do not eyeball it. Use the full 10ml.
- Add the second nic shot. Same again. Every drop. The strength calculation assumes both shots go in completely.
- Seal it tight. Replace the nozzle and cap. Make sure it is properly closed. You are about to shake this vigorously, and a 120ml bottle of liquid hitting your carpet is not a small cleanup.
- Shake hard for forty-five seconds. Longer than a 50ml because there is more liquid to blend. The two nic shots need to distribute evenly through the full 100ml of flavoured base. You will see streaks and layers at first. Keep going until the entire bottle looks uniform in colour and texture.
- Set it down, then shake again. Two or three minutes of rest. Then another fifteen to twenty seconds of shaking. This catches any pockets the first round missed.
- Fill and vape. Fruit and ice flavours are usually good immediately. Dessert and tobacco can benefit from resting the sealed bottle overnight before the first fill. Not essential, but the flavour tends to round out with a short steep.
The extra step people skip: the second shake. With 120ml of liquid, it is harder to get complete distribution in one go compared to a smaller bottle. That second shake after resting is the difference between consistent strength across every tank fill and a bottle that starts strong and finishes weak.
Best 100ml Shortfill Flavours
The range of 100ml shortfill flavours is vast, so you’re bound to find something you’ll love.
Fruit and Tropical
The safe category and the volume leader. Mango, watermelon, mixed berry, passion fruit, grape, apple, citrus blends. Shortfill fruit profiles run deeper than their 10ml nic salt equivalents. More layering, more complexity per draw.
A 10ml might be "strawberry kiwi." A 100ml version from the same brand might add a guava note and a cooler finish. The extra development time that shortfill manufacturers invest shows up in the flavour.
Dessert and Bakery
The category where 100ml shortfills genuinely make their case. Custard, lemon tart, cheesecake, jam roly-poly, caramel, vanilla sponge, cinnamon danish.
VG-heavy blends carry sweetness naturally, so dessert notes land richer and smoother at 70/30 or 80/20 than they would in a thinner liquid. Dinner Lady's entire reputation was built here.
One thing to account for: sweet liquids build coil residue faster. A heavy dessert rotation means replacing vape coils more frequently. Budget an extra pack per month if dessert is your main category.
Menthol and Ice
Cool profiles that work well in VG-heavy format. The thickness softens menthol into a rolling coolness rather than a sharp spike. Some vapers prefer that. If you want aggressive menthol sharpness, a thinner 50/50 nic salt delivers more bite. At 70/30, menthol is smoother and more sustained.
Tobacco
Quiet sellers but loyal ones. A well-made RY4 or Virginia blend at 100ml through a sub-ohm tank is the kind of vape that does not make anyone's "best of" list but gets reordered month after month. Tobacco profiles also benefit more from steeping than any other category. Give them two to three days sealed after mixing and the flavour deepens noticeably.
Drinks and Candy
Cola, coffee, energy drink, mojito, bubblegum, sour candy. The smallest category but steady. Buying 100ml of a niche flavour is a bigger commitment than grabbing a 50ml to try, so make sure you genuinely like the profile before going large. A 10ml sample first is sensible if the brand offers one.
What VG/PG Ratio Are 100ml Shortfills?
Most shortfills sit at 70/30 or 80/20 VG/PG and occasionally 60/40.
• 70/30: The standard. Dense vapour, balanced flavour, works reliably in every sub-ohm tank. The 70/30 shortfill collection filters to this ratio specifically.
• 80/20: Thicker, cloudier, and a softer throat hit. Slightly less flavour sharpness than 70/30 because there is less PG carrying the taste. Best for vapers who prioritise cloud density over flavour definition.
• 60/40: Less common at 100ml but it exists. Thinner than the norm. Works in some pod mods with 0.4ohm coils, though most vapers buying 100ml bottles are running sub-ohm setups where 70/30 is the better fit.
The ratio is printed on the bottle. Match it to your coil. Sub-ohm coils with large wicking ports handle 70/30 and 80/20 without issue. Smaller coils above 0.6ohm do not.
Best Devices for 100ml Shortfills
Here are some device suggestions to pair your 100ml shortfill with.
Sub-Ohm Tanks
Where 100ml shortfills belong. Coils at 0.15ohm to 0.5ohm, wattage between 30W and 80W, large wicking channels built for thick liquid. The SMOK TFV series, Freemax Mesh Pro, Horizontech Falcon, Uwell Valyrian, and Geekvape Zeus all fit this bracket. Browse the full vape tank range for compatible hardware.
Regulated Box Mods
The power source that drives the tanks above. Adjustable wattage lets you dial in the exact output your coil needs. With VG-heavy liquid, hitting the right wattage matters more than with thinner blends because under-powering a thick liquid produces thin, flavourless vapour and over-powering it burns the cotton before the wick re-saturates.
RDAs, RTAs, and Rebuildables
If you build, you already know. 70/30 is the standard dripping ratio for a reason. A 100ml bottle sitting next to an RDA is the most cost-effective way to vape in the UK, full stop.
Not for Pod Kits
Pod coils above 0.6ohm cannot wick VG-heavy liquid fast enough. Dry hits, muted flavour, shortened coil life. If your device runs a 0.8ohm or 1.0ohm coil, stay with 10ml e-liquids at 50/50. The shortfill format is built for sub-ohm gear.
How to Store 100ml Shortfills
A 100ml bottle sticks around longer than a 50ml. Two to three weeks at steady use, sometimes more. Proper storage keeps the last fill tasting as good as the first.
- Cap on, always. Between every fill. VG pulls moisture from open air, which gradually thins the liquid and dulls the flavour. The cap is the single most effective thing you can do for shelf life.
- Upright position. Large bottles put more pressure on a loose nozzle than small ones. Store upright in a drawer, shelf, or cupboard. Lying on its side invites slow leaks, especially with thinner 60/40 blends.
- Cool, dark, room temperature. Heat degrades nicotine. UV light breaks down flavour compounds. A kitchen drawer or bedroom shelf is fine. A windowsill, car glovebox, or radiator shelf is not.
- Expect slight colour changes. Nicotine oxidises over time. The liquid will shift toward a faint amber tint. Normal. No effect on taste or safety within a reasonable timeframe.
- Cold weather thickens the liquid. VG gets sluggish when cold. If the bottle has been sitting in an unheated room and feels heavy when you try to fill, hold it between your palms for a minute. It loosens up. Do not use a microwave, hairdryer, or any external heat.
- Give it a shake before each fill. Not strictly necessary if you mixed well at the start, but a brief shake before refilling your tank keeps the nicotine distribution even throughout the bottle's lifespan. Takes two seconds. Worth the habit.
