Bar Series 100ml Shortfill at £11.99 explained

Bar Series 100ml Shortfill E-Liquid is a flavoured, nicotine-free base sold in a large bottle, and it is listed here at £11.99. That works out at roughly 12p per millilitre, which is the whole argument for the format: you buy a lot of liquid in one go and pay far less per ml than you would across a stack of 10ml bottles. This listing covers the range as a whole, so the flavour you receive depends on the option selected at checkout. If you already know the profile you want, the individual pages inside the Bar Series collection are the quickest route, since each one carries its own photo and price.

Bar Series is a name most UK vapers recognise from disposable-style flavours. The 100ml line takes the same fruit-led, ice-heavy approach and puts it in a bottle you can pour into your own tank. Flavours stocked alongside this listing include Cola Ice, Apple Peach, Sweet Strawberry and Strawberry Raspberry Cherry, which currently sell at £12.95 each. Availability moves around, so treat that list as a snapshot rather than a promise.

In practical terms, what you are buying is 100ml of flavoured liquid containing no nicotine whatsoever. A 100ml shortfill is normally supplied in a 120ml bottle, so there is deliberate empty space inside. That headroom is the defining feature of every shortfill e-liquid, and it is the reason these bottles are filed separately from standard 10ml refills. You can vape the liquid exactly as it arrives, or you can add nicotine shots to reach a low strength of your choosing.

The rest of this guide walks through what that means day to day: how the mixing maths works, how the flavours tend to behave, which devices suit them, how long a bottle lasts, and what to do when something goes wrong. It is written for adults who already smoke or vape and want to understand the product before they spend money. If you are under 18, or you have never used nicotine, this product is not aimed at you.

Why the bottle is not quite full: how shortfills work

Open the box and the bottle looks slightly under-filled. That is by design. In the UK, e-liquid containing nicotine can only be sold in containers of 10ml or less, with a ceiling of 20mg per millilitre. Nicotine-free liquid is outside that bottle-size rule, so manufacturers fill a large bottle with flavoured base at 0mg, leave empty space at the top, and let customers add nicotine separately in small bottles called shots.

A nicotine shot is a 10ml bottle of unflavoured nicotine in a VG and PG carrier, most commonly 18mg or 20mg. You pour it into the headroom, refit the cap and shake. The nicotine spreads through the whole bottle, and the flavour is diluted a little in the process, which is why shortfill flavours are generally built to tolerate that dilution. There is nothing exotic about the chemistry. It is the same set of ingredients as a conventional bottle, just assembled by you rather than at the factory.

The key point on this listing is that the strength shown is 0mg and the bottle is sold as exactly that. Nothing is added unless you add it. A fair number of buyers never touch a shot and simply vape the liquid nicotine-free, which makes a bottle like this a handy way to keep the habit of vaping while cutting out the nicotine. If that sounds like you, the wider nicotine-free e-liquid range follows the same logic at smaller bottle sizes.

One caution is worth stating plainly. Shots are not included with the bottle, so if you want a strength, sort that out before the bottle arrives rather than after. Stick to a freebase shot designed for mixing into shortfills. Nicotine salt is a different formulation with its own category, and it is not interchangeable with the standard shot used here. Mixing the two in the same bottle can give a strength that is hard to predict, so keep them apart.

Flavour profile across the Bar Series 100ml range

Going by the names and the house style of the range, Bar Series 100ml leans towards fruit, cola and cooling profiles rather than complex desserts or tobacco blends. The flavours listed alongside this one are Cola Ice, Apple Peach, Sweet Strawberry and Strawberry Raspberry Cherry. That tells you most of what you need to know about the direction: familiar, sweet and easy to recognise within a puff or two.

Cola Ice pairs a fizzy cola profile with a cooling finish on the exhale. Apple Peach sets crisp apple against softer stone fruit, which typically reads as a juicy, lightly tart blend. Sweet Strawberry is the most direct of the four, a plain strawberry with a candy-style finish. Strawberry Raspberry Cherry stacks three red fruits and usually lands somewhere between jam and sherbet. Treat these as expectations drawn from the names rather than lab-grade tasting notes, because palate, device and wattage all change how a flavour comes across.

If you are used to disposable vapes, this is the family resemblance you will spot. The range is clearly designed to echo the bar flavours people already know, only poured into a refillable device. At 0mg, or at the low strengths you get after adding shots, the throat hit is gentle, so the flavour sits at the front rather than being masked by nicotine bite.

Two practical side effects of sweet, cooled flavours are worth knowing before you commit to 100ml of one. Sweeteners caramelise on a coil faster than plain liquid does, so coils can tire sooner than they would on a lightly sweetened blend. And many people find cooling agents stand out more at low nicotine, since there is less harshness competing with them. Neither is a fault. Both are simply how this style of e-liquid behaves, and both are easy to manage with a fresh coil and a sensible wattage.

Who a 100ml Bar Series bottle suits, and who it does not

Three kinds of buyer tend to get the most out of a bottle like this. The first is the vaper who has worked through enough 10ml bottles to notice how quickly the cost builds up. At around 12p per millilitre, a 100ml shortfill is a deliberate move towards value, and it only makes sense if you run an open tank or refillable device that can take the volume. The second is the person leaving disposables behind who wants the same fruit-and-ice flavours without binning a plastic body every few days. The third is the nicotine-reducer, who starts with shots and gradually uses fewer until the bottle is vaped at 0mg.

It is less suited to some people, and it is better to say so now. If you currently rely on 10mg or 20mg nicotine salts, a shortfill with a couple of shots tops out at about 3mg, which is a big drop in strength and may not satisfy you. Plenty of people find that jump too large and end up reaching for something stronger by mid-afternoon. Those buyers are usually better served by a nicotine salt e-liquid in a pod or low-power device, where higher strength is part of the design.

It is also a poor fit for sealed pod systems with prefilled cartridges, since you cannot refill them, and for anyone who likes to change flavour every few days, because 100ml commits you to one profile for weeks.

Finally, the obvious but important point: this is for adults. Vaping products are sold only to over-18s in the UK, and nicotine in any form is not intended for people who do not already use it. Keep bottles and shots out of reach of children and pets, and do not buy on behalf of anyone who is under age.

Specifications, strength maths and running costs

Numbers first, because they are what decide whether a bottle this size is worth the money.

• Liquid volume: 100ml of flavoured e-liquid.
• Nicotine as sold: 0mg, so nicotine-free.
• Bottle size: typically 120ml, leaving room for two 10ml shots. Check the label when it arrives.
• Price: £11.99 for the bottle, close to 12p per millilitre.
• VG/PG ratio: printed on the bottle and flavour listings. Shortfills as a class are mostly high VG, but always read the label.

The strength maths is simple. Nicotine strength is the total milligrams of nicotine divided by the total volume. Two 18mg shots add 360mg to 120ml, giving 3mg per millilitre. Two 20mg shots add 400mg, which is a shade over 3.3mg. A single 18mg shot in the full 100ml gives 180mg across 110ml, about 1.6mg, and a single 20mg shot gives roughly 1.8mg. Work from these figures rather than from the rounded numbers on a shot label.

Running cost depends on your device. Open sub-ohm tanks commonly use somewhere around 3ml to 5ml of liquid a day, while lower-powered pod devices often use 1ml to 2ml. On those assumptions one bottle lasts about three to five weeks at sub-ohm usage and a good deal longer on a pod. Once two shots go in, the same bottle becomes 120ml, which stretches those windows further. These are estimates, not guarantees, since wattage, draw length and coil condition all change consumption.

As a value check, a 10ml Bar Series nicotine salt bottle currently lists at £2.95 on this site. Ten of them would cost £29.50 for the same volume, against £11.99 here. The two are not the same product, because one is a high-strength salt and the other a low-strength freebase, but the per-millilitre gap shows why heavy daily users end up on shortfills.

How to add shots and mix the bottle properly

Mixing takes about two minutes, and most of the mistakes happen in the first thirty seconds. Work over a sink or a tray, because nicotine on skin is best washed off promptly with water.

• Shake the shortfill first. Flavour compounds settle a little in transit, and a quick shake wakes the bottle up before you open it.
• Open the neck. Most 100ml shortfill bottles have a nozzle that needs to be twisted or pulled off to leave a wide opening. Look at the cap before forcing anything.
• Add the shots. Snip the tip of each 10ml shot and squeeze it in. Two shots gives about 3mg, one shot gives roughly 1.6mg to 1.8mg.
• Refit the nozzle and cap. Check the seal, because a half-fitted cap is the usual cause of a leaking bottle.
• Shake for a full minute. This is longer than most people think. Poorly mixed bottles give a harsh hit at the start and a weak one at the end.
• Rest it. Leave it upright for a few hours before the first fill, and give it another shake before you top up your tank.

If you only want to use one shot, you can simply add it to the full 100ml and accept the lower strength. A cleaner approach for people who want precision is to decant half the bottle into an empty 60ml bottle, add one shot to that, and keep the remaining half at 0mg. You end up with 60ml at 3mg when using an 18mg shot, and 50ml untouched. It takes slightly more effort but gives you two strengths from one purchase.

A word on what not to do. Do not top the bottle up with other flavoured liquids, because the headroom is sized for shots and an overfull bottle is awkward to shake and easy to spill. Do not heat the bottle to speed things along. Warm water baths can degrade flavour and nicotine, and the time saved is minimal. Patience and a firm shake do the job.

Which devices and coils work best with this shortfill

A shortfill is only as good as the device it goes into, so this section matters more than it looks. Liquids sold in 100ml bottles are usually built around a higher proportion of vegetable glycerine, which gives thicker vapour and a smoother throat feel but flows more slowly through a wick. That is why they are traditionally paired with sub-ohm tanks, where larger coil openings and higher wattages cope with the thickness. Always read the VG/PG ratio on the label and match your hardware to it.

For a tank-style setup, vape kits built around a sub-ohm tank are the natural home. Coil resistances of around 0.15 to 0.6 ohm are common, run at wattages within the range printed on the coil. Start at the lower end of that range, because sweet fruit liquids can scorch at the top end, particularly with a fresh coil. Prime new coils by dripping a few drops directly onto the cotton and letting the tank sit for five to ten minutes before the first draw.

Refillable pod systems can work too, with a caveat. Pods with coils around 0.6 to 1.0 ohm generally handle thicker liquid acceptably, but very tight coils of 1.2 ohm and above may struggle to keep up with a high-VG base, giving weak flavour or dry hits. If you are shopping for that route, browse refillable vape pods and check the manufacturer guidance on VG suitability before you buy. Sealed, prefilled pods cannot be refilled and are not compatible with a bottle like this.

A few habits help whichever hardware you choose. Fill gently, tilting the tank and avoiding the central airflow tube. Do not fill to the brim, as leaving a small air gap reduces leaks caused by pressure changes. Keep the tank upright when stored. And if flavour dulls long before the bottle is finished, suspect the coil before you suspect the liquid, as covered in the troubleshooting section below.

Choosing a nicotine strength for your bottle

There are really only three sensible destinations for a 100ml shortfill: 0mg, around 1.5mg, or around 3mg. Anything beyond that needs more shots than the bottle has room for, and at that point the format is working against you.

0mg means leaving the bottle exactly as supplied. There is no throat hit, just flavour and vapour. This suits people who have finished with nicotine, people who vape purely for the habit and the taste, and people who like to keep a nicotine-free option for evenings. Because the flavour is not competing with nicotine bite, it can seem more pronounced than you remember from a stronger liquid.

Around 1.5mg to 1.8mg comes from adding a single shot to the full bottle. It gives a mild throat sensation and tends to suit people who are already reducing their intake or who have a moderate daily habit combined with a powerful tank that delivers a lot of vapour per puff.

Around 3mg comes from two shots, and it is the usual choice for people who want a noticeable throat hit from a sub-ohm device. It is the ceiling for this format, so if 3mg does not feel like enough, the answer is a different product rather than a third shot. Our nicotine salt range covers the higher strengths and is designed for the lower-power devices that suit them.

A sensible principle is to start lower than you think you need and adjust on the next bottle. Larger clouds mean more nicotine per puff, so a strength that felt weak in a small pod can feel strong in a big tank. Nicotine is addictive, and nobody who does not already use it should begin. If you are unsure whether a strength suits your health, a pharmacist or GP can advise.

Storage, shelf life and keeping the flavour fresh

Light, heat and air are the three things that age e-liquid, and a 100ml bottle spends a long time exposed to all of them if you are careless. The good news is that the fixes cost nothing.

Keep the bottle somewhere cool and dark, such as a cupboard or drawer. A windowsill, a radiator shelf or a parked car in summer will speed up discolouration and flavour loss. Make sure the cap is tight after every use, as air getting into the bottle is what slowly flattens the top notes in fruit and cooling flavours. Check the best-before date printed on the label, and treat it as your guide rather than guessing.

Once you add nicotine, the clock changes slightly. Nicotine oxidises over time, and the most visible sign is the liquid turning darker, going from pale yellow to amber and eventually deeper brown. A modest darkening over a few weeks is normal and does not necessarily ruin the taste, but it is a reason to avoid mixing the full bottle up front if it is going to last you two months. Mixing in stages, as described earlier, keeps the unmixed portion fresher.

Two further habits are worth adopting. Write the date and strength on the bottle with a marker once you have added shots, because forgetting what is in a three-week-old bottle is easier than it sounds. And decant a few days' worth into a small bottle for carrying, instead of lugging the large one around and opening it repeatedly.

Finally, safety. Keep every bottle out of reach of children and pets, even when it contains no nicotine, and keep shots in a place that is clearly separate from food and drink. If liquid containing nicotine gets onto skin, wash it off with water straight away. If it is swallowed or splashed in the eyes, seek medical advice promptly.

Troubleshooting dry hits, leaks and fading flavour

When a shortfill misbehaves, the liquid is rarely the culprit. Most problems trace back to the coil, the fill or the settings, and they are usually fixable in a couple of minutes.

• Dry or burnt hits: the wick is not saturated, the wattage is too high, or the tank is nearly empty. Top up, let the coil soak for a few minutes, drop the power, and take shorter puffs with a pause between them.
• Gurgling or spitting: too much condensation or an overfilled tank. Dry out the airflow channel, reduce the fill level and check that the coil is seated properly.
• Leaking from the tank: usually a poorly tightened base, a cracked seal, or overfilling. Re-seat the base, replace any perished O-rings, and avoid the very top of the fill window.
• Leaking from the bottle: check the nozzle and cap seat fully after mixing. Store the bottle upright to keep liquid off the seal.
• Harsh hit at first, weak at the end: the shots were not shaken in long enough. Give the bottle a firm minute of mixing and rest it.
• Flavour fading before the bottle is done: by far the most common complaint with sweet fruit liquids, and almost always a tired coil.

That last point deserves emphasis. Because sweeteners build up as a film on the cotton, a coil that tasted vivid for a week can go flat afterwards even though the liquid itself is fine. Replacing it is cheaper than abandoning a good bottle, and our replacement coils cover the common tank and pod formats. As a rough guide, many users swap coils every one to three weeks on sweet liquids, though your own results will depend on wattage and how heavily you vape.

If you have checked all of the above and still have a problem with the liquid itself, such as an odd smell or colour straight out of the box, stop using it and get in touch with the team.

Honest pros and cons of buying 100ml in one go

Volume is a double-edged sword, so here is the balanced view before you decide.

On the plus side:

• Price per millilitre. At roughly 12p, this is well below what the same volume costs in 10ml bottles.
• Adjustable strength. You choose between 0mg, about 1.5mg and about 3mg, and you can change it between bottles.
• Familiar flavours. The range borrows the fruit-and-ice character of disposable bar flavours, which is a comfortable landing for people switching away from them.
• Fewer bottles and less packaging. One purchase replaces a drawer full of small ones.
• A path to zero nicotine. Dropping from two shots to one, then none, is straightforward.

On the downside:

• It is one flavour for weeks. If you get bored easily, 100ml is a lot of the same thing.
• Extra purchase and extra step. Shots are separate, and you have to mix them correctly.
• A low strength ceiling. About 3mg is the maximum, which will not suit people used to strong nicotine salts.
• Device limits. It needs an open tank or refillable pod, not a sealed cartridge system.
• Shelf life after mixing. Large bottles with nicotine added can darken before you finish them.

If the cost per bottle is the deciding factor, it is also worth comparing against current vape deals, because multibuy offers on smaller bottles occasionally narrow the gap. For anyone who knows they like the flavour and has a suitable device, though, the arithmetic usually favours the larger bottle. For everyone else, it is simply a matter of being honest about how much of one flavour you will actually get through.

Delivery, returns and the age check

Ordering vape products in the UK involves one step that most online shopping does not: proving your age. Everything sold here is for adults aged 18 or over, and orders may be held until that has been confirmed. The process, and what you may be asked for, is set out on our age verification page, so it is worth reading before you place an order rather than discovering it at checkout.

Delivery details are kept in one place so they stay accurate. Our shipping information covers the available methods, costs, dispatch timings and any restrictions that apply to your address. Because those details can change, they are deliberately not repeated here. A 100ml bottle is heavy relative to a 10ml one, so it is worth checking the shipping page if you are combining it with other items in a single order.

When the parcel arrives, check it straight away. Look at the label to confirm the flavour, the 100ml volume, the 0mg strength and the VG/PG ratio. Confirm the nozzle and cap are intact, and that nothing has leaked in transit. If you planned to use nicotine shots, make sure you have them to hand before you open the bottle, since adding them is a one-time job best done in a single sitting.

If something is wrong, such as a damaged bottle, the wrong flavour or a missing item, photograph the packaging and the product before you do anything else and keep the box. For returns terms and answers to common questions, see our FAQ page, which holds the current policy. As a consumable product, e-liquid is often handled differently from hardware where returns are concerned, so read the terms before ordering rather than after. The team can also help with anything the pages do not cover.
