Bar Series Spearmint 100ml at a Glance

Spearmint is one of the calmer flavours in the Bar Series catalogue, and for plenty of vapers that is the whole appeal. This listing is for a single 100ml shortfill bottle of Spearmint at 0mg, priced at £11.99. There is no battery, no coil and no puff count attached to it. It is liquid only, intended to be poured into a refillable tank, pod or sub-ohm kit that you already own.

The brand is better known for loud, fruit-forward profiles, so a mint on the same shelf stands out. If you want to see what else sits alongside it, the full Bar Series range is collected on one page, and it is a handy way to compare flavours before committing to such a large bottle.

What you are paying for is volume and simplicity. A nicotine-free liquid can be sold in a big bottle, which is why this sits among the shortfill e-liquids and not with the small 10ml bottles. The liquid inside measures 100ml, and the bottle is usually larger, leaving headroom should you choose to add nicotine shots of your own. The capacity printed on the label is the figure to rely on when the parcel arrives.

Here is the short version of what you get:

• Flavour: Spearmint, a sweet, herbal mint rather than a sharp, icy one.
• Strength: 0mg as supplied.
• Liquid volume: 100ml.
• Price: £11.99 per bottle.
• Format: Shortfill, for refillable devices only.

It is worth saying plainly who this is not for. It will not work in a disposable or a sealed prefilled pod, because those cannot be opened or topped up. It is also not a nicotine product in its own right. Nothing here is meant to tempt anyone who does not already use nicotine, and the 0mg figure means it can be used exactly as it comes. The rest of this guide covers how the format works, how to mix shots safely if you want them, which devices suit it, and what to do when a tank misbehaves.

How a 100ml Shortfill Bottle Is Made to Work

The odd proportions of a shortfill bottle are deliberate. Pick one up and you will see the liquid stops well below the neck, because the container is larger than its contents. That empty space is reserved for nicotine shots, and it is the reason this format exists in the UK at all. Bottles of this kind are commonly 120ml in capacity, although the figure on your label is the one to trust.

The logic comes from the rules. Nicotine-containing e-liquid has to be sold in bottles of 10ml or less, with strength capped at 20mg/ml. A nicotine-free liquid sits outside that bottle limit, so makers fill a big bottle with flavoured base and sell nicotine separately, usually as a 10ml shot at 18mg/ml. You decide whether the two ever meet. Nothing is mixed on your behalf at the point of sale.

Because the flavour is already balanced in the base, a shot does not rewrite the taste. Shots are typically a neutral VG/PG blend that adds strength without adding flavour. The one side effect is dilution. Spread the same amount of spearmint across 120ml instead of 100ml and it is fractionally softer, which most people never notice but a few fussy tasters do. If that sounds like you, one shot is the gentler option.

It helps to see where this sits among the wider e-liquids category, where three broad formats overlap:

• Shortfill: large, nicotine-free bottles with room for shots. Low cost per millilitre, best suited to tanks and refillable pods.
• 10ml freebase: small bottles that already contain nicotine, usually used in sub-ohm and mid-power setups.
• Nic salt: small bottles with smoother, higher-strength nicotine, usually used in low-power pod devices.

Two practical points before you order. First, shortfills are not made for sealed, prefilled cartridges; you need a fill port, a tank or a refillable pod. Second, 100ml is a lot of liquid to keep open. Decanting a few millilitres into a small dropper bottle for everyday use keeps the main bottle sealed, clean and fresher for longer, and it makes filling a tank a much tidier job.

Spearmint Flavour Notes Compared With Peppermint

Mint flavours split into two camps, and knowing which camp spearmint belongs to saves disappointment. Peppermint leans on menthol, which delivers that sharp, almost icy blast at the back of the throat. Spearmint gets its character from a different compound, carvone, which reads as sweeter, greener and rounder. Think of the mint in chewing gum or a garden mojito rather than a strong throat sweet.

On the inhale, expect a soft herbal sweetness. On the exhale, the flavour tends to linger as a clean, slightly sugary mint without much bite. That makes it far easier to vape through a whole day than a heavy menthol, which can feel harsh after a few hours. It is a flavour you notice mostly on the breath and the palate rather than in the chest.

One honest caveat: the listing describes this product only as Spearmint, with no published notes about added cooling agents. Some mint liquids include a touch of cooling for a fresher finish and others do not. Bar Series does not state how pronounced the chill is, so treat your first tank as the real test. If you find it too mild, a slightly higher wattage generally pushes the flavour and any cooling forward. If it feels too cool, drop the power a notch and the profile softens.

Some quick tasting tips:

• Let the coil soak. Five minutes after filling prevents a dry first pull, which can taste scorched and ruin the first impression.
• Take gentle draws. Mint flavours open up with slower, longer pulls and can turn thin when you rush them.
• Clear your palate. Coffee, citrus and very sweet drinks dull or distort mint. Water between sessions helps.
• Try it at room temperature. A cold bottle left in a car boot or on a windowsill suppresses flavour and thickens the liquid.

Because this is a single-flavour profile, there is nowhere for it to hide. If you enjoy a clean, simple mint, that is a strength. If you expect layers of fruit and sweets, as in many other bottles from the same brand, you may find it plain, and a fruitier pick from the range will suit you better.

Who Spearmint Shortfill Makes Sense For

A bottle this size suits a particular sort of vaper, and it is easier to spot yourself in a list than in a description.

• The flavour-first vaper. Plenty of adults vape at 0mg purely for the taste and the hand-to-mouth habit. A nicotine-free e-liquid in a large bottle is the cheapest way to do that, and mint is a sensible all-day choice because it rarely gets tiring.
• The palate-reset buyer. If you run through sweet fruit and dessert liquids, a bottle of mint is a handy change of pace. Keeping a second tank filled with spearmint lets you swap when everything else starts to taste samey.
• The self-mixer. Adults who already use nicotine and like to fine-tune their strength get full control here. You choose none, one shot or two.
• The bulk buyer. If you vape heavily in a sub-ohm tank, small bottles run out fast and cost more per millilitre. A single large bottle changes the arithmetic.

It is just as important to be clear about who should look elsewhere. Anyone using a disposable or a sealed pod system cannot use a shortfill. Anyone who wants a no-fuss, charge-and-go device would be happier with something ready-made. And anyone who has never used nicotine has no reason to add it: this product is not an invitation to start.

Age is the other filter. You must be 18 or over to buy any vaping product, nicotine-free liquids included. The product is aimed at adults who already vape and who already own a refillable device.

There is also the question of commitment. A 100ml bottle of a single flavour is a lot of the same taste. If you are unsure that mint is for you, it is a fair move to try a smaller bottle first or to browse the wider selection before buying such a large volume. People who have vaped one flavour all day for years tend to be happy with the bulk format. People still hunting for a favourite are usually better rotating through smaller sizes first. A little honest self-assessment here saves money, and it saves a half-used bottle gathering dust on the shelf.

Price, Volume and Daily Cost in Numbers

Specifications for a liquid are short, which makes them easy to check. One bottle of Bar Series Spearmint costs £11.99. The strength is 0mg, the liquid volume is 100ml, and the format is shortfill. There is no puff count because there is no device, and no multibuy price is attached to this particular listing at the time of writing.

Divide price by volume and you land on roughly 12p per millilitre. For comparison, a small 10ml bottle priced at £3.50 works out at 35p per millilitre. The shortfill liquid therefore costs around a third as much, which is the entire commercial case for the format. It only pays off, of course, if you finish the bottle while the flavour is still fresh.

Daily cost depends entirely on how you vape. Here are two illustrative cases:

• Light pod use: a 2ml refillable pod emptied roughly once a day uses about 2ml, so 100ml lasts around 50 days and costs roughly 24p a day.
• Sub-ohm tank use: a tank holding 4ml and refilled three times a day uses about 12ml, so the bottle lasts a little over eight days and costs roughly £1.44 a day.

These are examples, not promises. Real consumption varies with wattage, coil resistance and puff length, and a high-power setup can get through liquid at a startling rate.

If cost is the deciding factor, it is worth checking the vape deals page before you check out, particularly if you are buying more than one bottle or pairing the liquid with a kit. Delivery is free once your basket reaches £20. One bottle sits under that line, but two come to £23.98 and clear it, which is often the neatest way to restock a flavour you already know you like.

Finally, remember that nicotine shots, if you want any, are a separate purchase with their own price. They are not included in the bottle, and they need to be factored into any comparison of total cost.

Mixing Nicotine Shots Safely, Step by Step

If you use the liquid at 0mg, skip ahead; nothing here applies to you. For adults who already use nicotine and want to add it, the process takes about two minutes and rewards a little care.

• Read both labels first. Confirm the bottle's capacity and the strength printed on the shot before you open anything.
• Work on a wipeable surface. Put a tissue or kitchen roll underneath and wash your hands.
• Remove the nozzle. It is usually a push-fit dropper tip. Pull it out cleanly and keep it from touching dirty surfaces.
• Add the shot. Squeeze the contents in, tilting the bottle slightly so the liquid runs down the inside wall rather than splashing.
• Refit and close. Press the nozzle back firmly, then fasten the cap fully.
• Shake for a minute. Thirty to sixty seconds of vigorous shaking disperses the nicotine evenly.
• Rest the bottle. A few hours, ideally overnight, lets the bubbles clear and the mix settle.
• Label it. Write the date and the resulting strength on a sticker. An unlabelled bottle is a hazard.

Shots are not the same thing as nic salts. A nicotine salt e-liquid is a ready-made 10ml bottle designed for low-power pod devices, with the nicotine already blended in a smoother form. A shot is a bare nicotine booster for topping up a shortfill. Muddling the two leads to a strength you did not plan on, so check what is written on the box before you pour.

A few safety points deserve repeating. Nicotine in concentrated form is hazardous: wipe spills straight away, wash skin with soap and water after any contact, and never leave open shots lying around where a child or pet could reach them. Do not overfill the bottle, as the headroom is calculated for a reason. Overfilling causes leaks, uneven mixing and a stronger result than intended. And if you pour a little into a dropper bottle for daily use, label that bottle as well, and shake the main one before decanting each time.

Picking a Strength: Nothing, One Shot or Two

The first decision is whether to add nicotine at all, and for plenty of buyers the answer is no. At 0mg the bottle is ready to vape and the sums are finished. Nobody who does not already use nicotine should start because a flavour sounds appealing. Nicotine is addictive, and this liquid does not need it to taste of spearmint.

For adults who do use nicotine, the arithmetic is simple if you have the labels to hand. Assuming a 120ml bottle and 18mg/ml shots:

• No shot: 0mg/ml, exactly as supplied.
• One 10ml shot: 180mg of nicotine in about 110ml, giving roughly 1.6mg/ml.
• Two 10ml shots: 360mg in 120ml, giving 3mg/ml.

Those figures change if your bottle or shot is a different size, so recalculate from the printed labels and do not rely on a web page. The general formula is the total nicotine in the shots, in milligrams, divided by the total liquid in millilitres.

As a loose rule of thumb, lower strengths tend to suit sub-ohm tanks, because those devices produce large clouds and deliver more liquid, and so more nicotine, with each puff. Higher strengths are usually paired with small, low-power pod devices, and those more often use nic salts than freebase shots. Throat hit is the other variable. Freebase nicotine feels sharper at the back of the throat as the strength climbs, and the cool, herbal edge of mint can make that sensation seem stronger than it really is.

So start low. You can add a second shot later but you cannot take one out. Signs that a mix is too strong include dizziness, nausea and a racing heart; if you notice them, stop vaping and get some fresh air.

Anyone using vaping to move away from cigarettes may find it useful to speak to a local stop smoking service, which can offer support that a bottle label cannot. Whatever you choose, keep every bottle and shot well out of reach of children.

Devices, Coils and Upgrades That Suit Mint

Shortfills need a device with a fill port. Beyond that, the match comes down to coil resistance and liquid thickness. Check the label for the VG/PG ratio, because it tells you what the liquid wants. Higher-VG liquids are thick and produce bigger vapour, and they wick best through sub-ohm coils with wide inlet holes. More balanced ratios flow easily through the smaller coils found in compact refillable pods.

Three routes work well:

• A sub-ohm tank on a mod or kit. The classic home for 100ml bottles. If you are starting from scratch, browse our vape kits and look for one with a top-fill tank holding 2ml to 5ml.
• A refillable pod system. Smaller, tidier and lower powered. Our refillable vape pods include options with a side or bottom fill port. Choose pod coils intended for freebase liquid, not only for nic salts.
• A pen-style starter kit. Mid-power tanks suit gentler, mouth-to-lung vaping with a moderate-strength mix.

Coils are the part that wears. Sweetened liquids tend to leave residue on the cotton and the heating element, so expect to change the coil more often than you would with an unsweetened liquid. As a rough guide, many people replace a coil after one to two weeks of regular use, or sooner if the flavour turns flat or burnt. Our replacement coils page lists compatible options by device, so check your tank's model before ordering.

A word on ghosting. Mint is famously clingy. If you switch a tank from spearmint to a fruit liquid without a thorough rinse and dry, the mint haunts the next flavour for days. If you vape several types, keep a dedicated tank for mint or buy a cheap second tank. Rinse the tank in warm water, let it dry completely and fit a fresh coil whenever you change flavour family.

Upgrades that actually improve the experience are modest: a tank with a better airflow ring, a spare coil pack, a small dropper bottle for tidy filling, and a pouch that keeps leaks off your clothes.

Storing Spearmint Liquid and Keeping It Fresh

Heat, light and air are the three things that age e-liquid. A cupboard handles all three at once, which is why it beats a dashboard, windowsill or bathroom shelf every time. Store the bottle upright, cap tightly closed, somewhere cool and dark, and out of reach of children and pets.

Unopened and kept properly, a sealed bottle holds its flavour for a long time, and the label will carry a best-before date or batch code worth noting when the parcel lands. Once opened, oxygen begins to work on the liquid. The visible signs are darkening and a slightly changed taste. Darkening is not always a fault, as nicotine in particular tends to deepen in colour, but if the flavour turns flat, bitter or oddly sharp, it has gone past its best.

Habits that help:

• Decant small amounts. A 10ml or 15ml dropper bottle for daily use limits how often the main bottle is opened.
• Wipe the nozzle. Residue around the tip attracts dust and can crust over the cap.
• Shake before use. Particularly after the bottle has been sitting a while, and always after adding a shot.
• Avoid temperature swings. A bottle that bounces between a cold garage and a warm kitchen thickens and thins repeatedly, which is not kind to the flavour.
• Keep it out of direct sunlight. Light degrades flavour compounds and nicotine.

Travel needs a little forethought. Pressure changes on a flight can push liquid out of a bottle with a loose nozzle, so close the cap tightly, seal the bottle in a zip bag and keep it upright. Decanting into a small bottle for your hand luggage is usually more sensible than carrying 100ml, and you should check the airline's current rules on liquids before you pack.

If you have added nicotine, label the bottle with the date and strength, and treat it as the one to finish first. Finally, never store e-liquid in a food or drink container, and keep it well apart from anything edible.

Honest Pros and Cons Before You Buy

Every bottle involves trade-offs, so it is fairer to lay them out side by side than to pretend there are none. Start with what works in this one's favour.

The advantages

• Low cost per millilitre, at roughly 12p, compared with small bottles.
• Supplied at 0mg, so it is ready to use with no mixing.
• Flexible: adults who use nicotine can add shots and set their own strength.
• A gentle, sweet mint that is easy to live with all day.
• Liquid only, so there are no batteries to charge and no electronics to throw away.
• Works in most refillable tanks and pods, whatever brand of device you own.

The drawbacks

• It is a lot of one flavour. If you tire of mint, you are stuck with most of a bottle.
• Refillable devices need upkeep: topping up, priming coils and changing them.
• Filling and mixing can be messy, and leaks are part of the learning curve.
• Mint lingers in tanks and can taint whatever flavour follows it.
• Nicotine shots, if wanted, are a separate cost and a separate step.
• A 100ml bottle is bulky to carry, so you will want a smaller bottle for daily use.
• The profile is a simple, single-note mint. People who want layered flavours may find it plain.

If you value convenience above everything else, a ready-made device may suit you better. Disposable vapes need no filling, no coils and no mixing, although they often work out dearer over time, cannot be refilled and create more waste. The two formats serve different habits rather than competing head to head.

The verdict, if you want one: buy this if you already own a refillable device, enjoy a clean mint and vape enough to use up a large bottle. Skip it if you are new to vaping and want simplicity, or if you are still working out which flavours you like.

Fixing Leaks, Burnt Hits and Faint Flavour

Most problems with a refillable setup come down to a handful of causes, and almost all of them are fixable in minutes. Work through the list below in order before blaming the liquid.

• Leaking from the tank. Usually overfilling, a loose seal or a worn O-ring. Fill only to the maximum line, check every threaded section is snug and replace tired rubber seals. Storing the tank upright when not in use helps too.
• Burnt or scorched taste. Commonly a dry coil from not letting it soak, or a coil that has reached the end of its life. Wait five minutes after filling, take a few short priming puffs without firing, and fit a fresh coil if the taste does not clear.
• Weak or faint flavour. Check the tank is not nearly empty and consider whether the coil is worn out. Raising the power slightly can help, within the range printed on the coil. Occasionally it is vaper's tongue, where you stop tasting a flavour you have used too long. Swapping to a different liquid for a few days usually resets it.
• Gurgling and spitting. Condensation in the airflow path or too much liquid around the coil. Blow gently through the mouthpiece with the tank off to clear it, and wipe the drip tip.
• Dry hits with a full tank. The liquid may be too thick for the coil, or the airflow too tight. Check the VG/PG ratio, open the airflow a little and lower the wattage.
• Sticky, gunky residue. A sign of sweeteners building up on the coil. Change the coil and rinse the tank thoroughly.

A mint-specific note: if the flavour seems muddy, a previous liquid is probably still in the tank. Strip it down, rinse every part in warm water and dry it fully before refilling. A cotton bud helps with the tight corners around the base.

If you have tried the above and a bottle still seems off, such as an odd smell, cloudy liquid or a leaking cap on arrival, stop using it and get in touch with your order number and a photo. Do not carry on with a liquid you suspect is faulty, and never keep using a device that gets unusually hot.

Age checks are a legal requirement and not an optional extra. You must be 18 or over to buy any vaping product, nicotine-free liquid included, and verification is part of the buying process. Our age verification page explains how it works, so you can have what you need to hand and avoid delays.

A few buying tips to finish:

• Confirm your device is refillable before committing to 100ml.
• Order nicotine shots at the same time if you want them; they are not included.
• Check the label when the parcel arrives, noting the capacity, batch code and date.
• Stand the bottle upright and look for weeping around the cap before putting it away.
• Think about a small dropper bottle for daily use, so the main bottle stays sealed.

The questions below cover the ones we hear most often about this specific bottle. Whatever you choose, vape responsibly, keep everything out of reach of children, and remember that anyone who does not already use nicotine has no reason to start.
