Overview: what Nasty Juice 50ml Devil Teeth is

Nasty Juice 50ml Devil Teeth is a nicotine-free shortfill e-liquid from Nasty, a brand that has been on UK shelves for years and is stocked by most independent vape shops. It is sold as 50ml of 0mg liquid in a 60ml bottle, which leaves headroom so you can add a 10ml nicotine shot if you want to vape with nicotine. The Nasty 50ml range is mixed at a high VG ratio, typically 70VG/30PG, which is built for sub-ohm tanks and mesh coils rather than small pod systems. In our catalogue the flavour is listed as a melon and mint profile, so expect a juicy fruit lead with a cool finish rather than a dessert or tobacco style.

Because this is a refill liquid and not a ready-made device, the experience depends on the kit you pour it into. That is the main difference from the single-use products many vapers used to buy. Disposable vapes have been banned from sale in Great Britain since 1 June 2025, and a lot of former disposable users have moved to refillable pod kits or sub-ohm starter kits. A 50ml shortfill such as Devil Teeth is one of the cheaper ways to keep a refillable device running, because the cost per millilitre is far lower than 10ml nicotine salt bottles.

This guide goes through flavour, vapour output, how the bottle is designed, what hardware suits it, how to choose a nicotine strength, who it suits, how to mix and fill it, what to do when something goes wrong, and how the cost compares with other 50ml shortfills. We have tried to be straight about trade-offs. Devil Teeth is a sensible, widely available choice, but it is not the right liquid for every device or every vaper.

Flavour profile: melon with a cool mint finish

Devil Teeth sits in the fruit-and-cool category. The lead note is melon, and the mint arrives on the exhale and lingers for a second or two afterwards. Melon in e-liquid usually reads somewhere between honeydew and a mild watermelon: sweet, slightly watery and a little floral rather than sharp. Mint is the part that stops it from tasting flat or sugary, and it gives the vape a clean aftertaste. If you have vaped menthol or ice flavours before, think of the cooling as moderate. It is noticeable, but it is not the heavy, throat-chilling hit you get from an extra-strong menthol.

Flavour perception varies from person to person and from device to device, so treat the following as a guide rather than a promise:

• Inhale: light, juicy melon sweetness with a smooth feel at lower wattages
• Exhale: the mint comes through and the fruit softens slightly
• Aftertaste: a clean, cool finish that does not coat the mouth heavily
• Sweetness: medium, so less sticky than dessert or bubblegum profiles
• Coolness: mild to moderate, noticeable but not aggressive

The way you set up your device changes how much of each note you taste. At lower wattages on the coil's recommended range, the melon tends to be clearer and the mint more subtle. Push the wattage up and the vapour gets warmer and bigger, which can mute some of the delicate fruit character and make the mint feel more prominent. Many vapers settle in the lower half of their coil's wattage range for fruit and mint liquids because the flavour tends to stay sharper there.

Nicotine also affects flavour. A 3mg/ml mix is gentle on the throat and lets the melon come through cleanly. If you push the strength higher, the throat hit grows and can compete with the mint, so the liquid may feel harsher even though the flavour recipe is the same. If you are looking for a sweeter, richer profile, this is probably not it. If you want a clean, fruity all-day vape that does not tire the palate quickly, it is a reasonable fit.

One honest caveat is that melon flavours can fade slightly as you vape them continuously, an effect often called vaper's tongue. If you notice the flavour dulling after a few days, switching to a different profile for a day, drinking water and rinsing your tank often brings it back. Many vapers keep a second bottle of a contrasting flavour for exactly this reason.

Performance and vapour delivery

A 70VG/30PG mix is thick, and that is the reason it produces dense vapour. VG (vegetable glycerine) makes the cloud, while PG (propylene glycol) carries flavour and gives a little throat hit. At this ratio you get large, smooth clouds and a soft inhale, but you also need a coil with big enough wicking holes to pull the liquid through quickly. In a sub-ohm tank with a mesh coil, Devil Teeth should give consistent vapour from the first puff to the last drops in the tank, provided the coil is properly primed.

Typical performance in a suitable setup looks like this:

• Direct-to-lung (DTL) sub-ohm vaping: large clouds, smooth draw, best suited to coils from about 0.15 to 0.4 ohm
• Power range: most mesh coils work in a window around 40W to 80W; pick the lower half for flavour and the upper half for cloud
• Consumption: a typical sub-ohm vaper uses somewhere between 3ml and 6ml a day, so a 50ml bottle can last roughly one to two weeks
• Throat hit at 0mg to 3mg: gentle, with the mint providing the main sensation

The main practical limit is hardware. Thick liquid can struggle in small, low-power pod kits with tight wicking, where it may cause dry hits, gurgling or weak flavour. If you own an under-15W pod device, a 70VG shortfill is usually a poor match, and a 50VG/50PG or nic salt liquid is more suitable. In that case check the list of nicotine salt options on the site instead. Devil Teeth is intended for kits where you can adjust wattage, or at least ones that list a sub-ohm or 0.3 ohm to 0.6 ohm coil as supported.

If you are moving from a disposable, the change in puff delivery can surprise you. A disposable gives a fixed, restricted draw at a modest power, while a sub-ohm kit moves a lot more air and vapour per puff. You may take fewer, bigger puffs and still find the liquid goes down faster than expected. It also means the nicotine delivery per puff is different, which is why a low strength such as 3mg/ml is usually the sensible starting point for a sub-ohm tank, and why higher strengths can feel overwhelming. We cover strength in detail further down.

Finally, remember that puff counts do not apply to e-liquid the way they do to disposable devices. The nearest equivalent is bottle life: how many days a 50ml bottle lasts depends on your wattage, puff length and habit, not on a fixed number printed on the label.

Design and build quality of the bottle

Because Devil Teeth is a liquid, build quality means the bottle, cap, labelling and the way the product is packaged. Nasty 50ml shortfills come in a 60ml plastic bottle with a long, narrow nozzle that fits most tank fill ports and standard nicotine shot bottles. The label shows the brand artwork, the flavour name, the volume, the VG/PG ratio and the legally required health warning, plus a batch code and best-before date you can quote if you ever need to contact the manufacturer or us about a problem.

Points worth knowing about the bottle:

• Capacity: 60ml bottle holding 50ml of liquid, leaving about 10ml of free space for a nic shot
• Nozzle: a thin dropper-style tip suited to filling small tank ports without spillage
• Cap: a child-resistant cap that needs a firm press-and-turn to open; this is a legal requirement for e-liquid containers
• Tamper evidence: a tamper-evident ring on the cap, which should be intact when your order arrives
• Material: plastic that is soft enough to squeeze gently to control the flow

When a bottle is shipped with a lot of free space, it is normal for the liquid to look as if it is only partly full. That empty space is deliberate, and it is the whole point of a shortfill. Do not treat it as under-filling. The label states 50ml, and the extra volume is what lets you add a shot and shake the mix without it overflowing.

We pack liquids in plain outer packaging and, where needed, cushion bottles so the caps are not forced during transit. If a bottle arrives leaking, cracked or with a broken seal, photograph it and contact us with your order number so we can sort out a replacement. Do not use liquid from a bottle with a broken tamper seal.

A small practical tip is to wipe the nozzle after each fill. E-liquid residue on the thread is the usual cause of sticky bottles, stained desks and a cap that becomes harder to turn. A paper towel does the job in a few seconds. Store the bottle upright, away from direct sunlight and heat, with the cap fully closed, and keep it out of reach of children and pets. Nicotine-free liquid still contains flavourings and carrier liquids that are not safe to swallow, and once you add a nicotine shot it becomes a nicotine-containing product that must be kept secure.

Battery and charging: what your device needs

The liquid has no battery of its own, so the question is what battery and power your kit has. Devil Teeth is a high-VG shortfill, which works best with devices that can deliver 40W or more. That points to three types of kit: a sub-ohm starter kit with a built-in battery, a box mod using one or two replaceable 18650 or 21700 cells, or a higher-powered pod mod with a rechargeable battery in the region of 1,500mAh to 3,000mAh. A larger battery will not make the liquid taste different, but it does mean you can vape at your preferred wattage for longer before charging.

As a rough guide to battery life, a 3.7V cell running a 60W output has to supply a current of around 16 amps at the cell, which is why high-drain cells with a suitable amp rating matter. Real devices vary because of regulation and efficiency. In simple terms, a 3,000mAh cell used at 60W typically gives a long day of moderate use, while a 1,500mAh built-in battery may need topping up once a day or more at the same power. If you are a heavy user, a device with a swappable 18650 pair or a fast-charging pod mod is more practical than a small built-in battery.

Some practical charging advice:

• Use the USB-C cable supplied with your kit, or a reputable replacement, and a standard 5V wall charger or a computer port
• Do not leave a device charging unattended overnight, especially one with replaceable cells
• Never use damaged, wrapped or mismatched 18650 cells, and always use cells from a recognised brand with the correct amp rating for your device
• Do not charge in direct sun, on a bed or under a pillow
• Stop using and replace any battery that is swollen, hot to the touch or smells unusual

Lithium batteries and vape devices should never go in household bins or general recycling. They can ignite in waste vehicles and sorting plants. In the UK, you can take old vape devices and loose cells to a battery or small-electrical recycling point. Many vape shops, supermarkets with a small-electricals bin, and council household waste recycling centres accept them, and retailers that sell vapes are expected to offer take-back. Tape over the terminals of loose cells before dropping them off.

If your kit is a small pod system with a battery under about 800mAh and a wattage ceiling below 20W, think carefully before choosing a 70VG shortfill. A thinner liquid, or a nic salt in 50VG/50PG, will usually work better there and be kinder to the battery.

Coil and mesh technology: choosing the right tank

Coil choice has more influence on how Devil Teeth tastes than almost anything else. A thick 70VG liquid needs a coil with generous wicking channels, and this is why mesh coils are the usual recommendation. A mesh coil is a flat sheet of fine metal mesh rolled into a cylinder, which gives a large surface area for heating. Compared with a traditional round-wire coil, mesh heats up faster, vaporises more liquid at the same wattage and tends to give a more even flavour. The trade-off is that mesh uses more liquid, and the coil can wear out sooner in a very sweet liquid.

Here is a simple matching guide:

• Mesh coil, 0.15 to 0.2 ohm: a good match for 60W to 80W cloud-chasing; strong vapour, higher liquid use
• Mesh coil, 0.2 to 0.3 ohm: the sweet spot for many users, at around 45W to 65W, with a balance of flavour and cloud
• Mesh coil, 0.3 to 0.4 ohm: lower power, around 35W to 50W, with tighter draw and better battery life
• Standard 0.6 ohm to 1.0 ohm coils: can handle 50VG liquids well, but 70VG may feel sluggish and prone to dry hits; use only if the coil lists high-VG support

Always follow the wattage range printed on the coil or in the manual. Going above it burns the cotton, and going well below it leaves the coil cold and the liquid spitting. Fruit and mint liquids tend to taste best in the lower half of the range.

Priming a new coil is essential with thick liquid. Drip a few drops straight onto the exposed cotton through the coil's holes, then fill the tank, fit the coil and let it sit for five to ten minutes so the cotton soaks through. Take a few gentle puffs without firing the device, then start at a low wattage and step up. Skipping this step is the most common reason for a burnt first taste.

Coil life depends on how much you vape and how sweet the liquid is. As a rough guide, expect between one and two weeks per mesh coil at moderate use. Signs that the coil is ending include a muted or slightly burnt taste, a darker coil head and reduced vapour. Devil Teeth is not an especially heavy sweetener, so coils may last a little longer with it than with dessert or sweet candy liquids, but this varies. Rinse the tank during each coil change and let it dry.

If you use a pod kit with a replaceable coil cartridge, check the pod's listed VG tolerance and fill port size before pouring a 70VG shortfill into it.

Nicotine strength guidance

Devil Teeth 50ml is sold at 0mg, which means no nicotine in the bottle. You can vape it nicotine-free as supplied, or you can add a nicotine shot to reach a low strength. This approach exists because UK rules limit the size of bottles that contain nicotine. Nicotine e-liquid must be sold in containers of no more than 10ml and at a maximum strength of 20mg/ml, so larger volumes are supplied as nicotine-free shortfills with separate shots.

The arithmetic is simple. A 10ml shot added to 50ml of 0mg liquid gives a 60ml total, so the final strength is the shot's strength multiplied by 10 and divided by 60:

• One 10ml shot of 18mg/ml: about 3mg/ml in the finished 60ml
• One 10ml shot of 20mg/ml: about 3.3mg/ml
• Two 10ml shots of 18mg/ml (needs a larger container, 70ml total): about 5.1mg/ml
• No shot: 0mg/ml, nicotine-free

For most sub-ohm vapers coming from cigarettes or from a disposable, 3mg/ml is where people usually start. A sub-ohm device delivers a lot of vapour per puff, so even a low strength can feel substantial. If you smoked heavily and find 3mg/ml leaves you reaching for a cigarette, you may step up to around 6mg/ml, but consider whether a mouth-to-lung setup with a nic salt would suit you better. High-strength liquids in high-power sub-ohm tanks can feel harsh and cause lightheadedness, nausea or a racing heart, so build up slowly.

A note on the UK 20mg limit. The 20mg/ml cap applies to every nicotine e-liquid and every prefilled vape device sold in the UK, and disposables were additionally restricted to small tank sizes before the single-use ban took effect in June 2025. A 20mg nic salt is designed for low-power pod kits, where a small amount of vapour carries a relatively strong dose. It is not designed for a sub-ohm tank using a 70VG liquid. If you are currently using a 20mg nic salt and move to a sub-ohm device with this shortfill, expect to need much less nicotine per millilitre.

If you do not use nicotine already, there is no reason to start. Vaping is intended for adults who smoke and want an alternative. Nicotine is addictive, and the 0mg version is a perfectly sensible way to enjoy the flavour without it. Always mix the shot in carefully, wash your hands after handling nicotine and label the finished bottle with the strength and date.

Who Devil Teeth is for, and who should look elsewhere

Devil Teeth is aimed at adult vapers who already own, or are buying, a refillable kit capable of handling a high-VG liquid. It is particularly relevant for people who were buying disposables until the ban and now want a lower-cost, refillable route, and for existing sub-ohm users who like a clean fruit and mint style.

It is a good fit if you:

• Use a sub-ohm tank, box mod or higher-powered pod mod with an adjustable wattage range
• Prefer fruit flavours with a cool finish over rich desserts, custards or tobacco blends
• Want a low-cost way to refill, since the cost per millilitre is much lower than 10ml bottles
• Vape at low nicotine strengths or nicotine-free and are comfortable mixing a shot
• Enjoy bigger, smoother clouds and a gentle throat hit

You should probably look elsewhere if you:

• Use a small, low-power pod kit with a tight coil, where 70VG liquid can cause dry hits and leaks
• Want a strong nicotine hit from a mouth-to-lung device; a 10ml nic salt at 10mg or 20mg suits that style better
• Dislike mint or cooling flavours of any intensity
• Want a plug-and-play device with no filling, mixing or maintenance, which is not what a shortfill provides
• Are under 18, pregnant, or a non-smoker, since nicotine products are not recommended for those groups

It also helps to be realistic about experience. If you are new to vaping, a shortfill adds a few extra steps compared with a pre-filled pod: you have to mix a shot, fill a tank and prime a coil. None of it is difficult, but it takes a little practice. A beginner can do this confidently after the first fill, and a sub-ohm starter kit with a clear instruction leaflet makes it easier. If you would like a simpler routine, a pod system with a 10ml nic salt of a similar flavour might be easier to manage, and our team can point you towards a suitable option if you contact us.

For those who smoke and are considering vaping to quit, the NHS offers free local stop smoking services, and some areas provide a free vape starter kit as part of the support. Using a vape alongside that support gives a stronger chance of success than going alone.

How to use: mixing, filling and your first puffs

Using Devil Teeth takes a few minutes the first time. Here is the sequence we recommend, whether you vape it at 0mg or add a shot.

• Step 1, check the seal: make sure the tamper ring on the cap is unbroken, then open the child-resistant cap by pressing down and turning.
• Step 2, decide on nicotine: if you want nicotine, pour a 10ml shot into the 60ml bottle. The bottle is sized to take exactly one shot. If you want nothing added, skip to step 4.
• Step 3, mix: close the cap tightly and shake the bottle gently for about 30 seconds. Rest it for a few hours, or overnight, so the nicotine blends fully.
• Step 4, prepare the coil: prime a new coil with a few drops of liquid directly on the cotton, fit it, then fill the tank to just below the maximum line.
• Step 5, wait: leave the tank for five to ten minutes so the cotton wicks the liquid.
• Step 6, set the power: begin at the lower end of the coil's recommended wattage range and take a few short puffs.
• Step 7, adjust: raise the wattage in small steps of 2W to 3W until the flavour and warmth feel right.

Take your time on the first few puffs. High-VG liquid builds up slowly, and a rushed start often causes a dry hit. Keep the tank at least a third full, because running it low raises the risk of burning the coil.

For flavour, many vapers find that fruit and mint liquids open up after the first tank. If the first fill tastes a little muted, give it another few puffs and a second prime before changing anything. Shortfills do not need long steeping the way some strongly flavoured nic salts or tobacco blends do, though a day of rest after adding a shot helps the nicotine blend evenly.

When you refill, tilt the tank, aim the nozzle at the inside wall of the fill port and squeeze gently. Avoid filling through the central airflow tube, which will flood the coil and cause leaking. Wipe the bottle and tank threads clean and make sure the fill port is closed before you pick the device up.

Store spare liquid in a cool place, out of direct sunlight, and keep a note of the date you added any shot. Use the mix within a few months for the best flavour, and respect the best-before date on the bottle. Vape only as an adult, and keep all liquids and devices away from children and pets.

Troubleshooting: fixing the common problems

Most problems with shortfills come down to the coil, the power setting or the filling method, rather than the liquid itself. Here are the issues we hear about most often and how to deal with them.

• Burnt or acrid taste: usually a dry hit from a coil that was not primed, a tank that ran low, or power set too high. Replace the coil if the taste persists, and start the new one lower.
• Weak or muted flavour: could be a tired coil, a wattage that is too low for the coil, or vaper's tongue. Try a fresh coil, bump the power by 3W, or switch flavours for a day.
• Gurgling or spitting: thick liquid pooling in the coil or airflow channels. Lower the power slightly, open the airflow a little more and check that the coil is seated properly.
• Leaking from the tank: often an overfilled tank, a loose coil, or a damaged O-ring. Refill to below the maximum line, tighten the base firmly and replace worn seals.
• Sticky bottle or fingers: wipe the nozzle after each fill and keep the bottle upright.
• Harsh throat hit: if you added a nic shot, the strength may be higher than you need. Consider mixing with a little extra 0mg liquid or using a lower-strength shot next time.
• Dry hits with a good coil: check that airflow is not clogged, that the tank has not run too low and that the wattage is within the coil's range.
• Device will not fire: check battery level, clean the contact points on the coil and tank, and make sure the device is switched on.

If you used a nic shot and notice that the colour of the liquid has darkened, do not be alarmed. Many e-liquids darken slowly over time, especially with nicotine, light and heat exposure. The flavour usually remains acceptable if the bottle is within its date, but if the smell or taste has changed sharply, stop using it.

If you suspect a fault with the liquid itself, such as a leaking bottle, a broken seal on arrival or a flavour that is clearly not what was ordered, contact us with your order number, the batch code from the label and a photo. We will advise on a replacement or refund. For general liquid and device safety, never use a liquid that has been exposed to extreme heat, and never mix liquids from different brands inside the same tank without cleaning the tank between flavours.

Keep a spare coil on hand. Coil failure is the most common reason a good liquid suddenly tastes wrong.

Value for money

The strongest argument for a shortfill is cost per millilitre. Devil Teeth starts at £3.50 for 50ml on this site, which works out at roughly 7p per ml. By comparison, a 10ml nic salt bottle at a typical UK price of around £3 to £4 costs 30p to 40p per ml, and a pre-filled pod pack costs more again for a smaller volume of liquid. If you vape every day, the gap is significant over a month.

Here is an indicative comparison, using rounded figures and assuming 5ml per day of use:

• 50ml shortfill at £3.50: about 10 days of liquid, so roughly £10 to £11 per month before the cost of a nic shot and coils
• 10ml nic salt at around £3.45: roughly 2 days of liquid at the same usage, so a much higher monthly bill
• Nicotine shot: adds a modest amount per bottle; check the current price when you order
• Coils: mesh coils typically cost a few pounds each in multi-packs and last one to two weeks, so factor in about £5 to £8 a month

Even after adding a shot and coils, running a sub-ohm kit on shortfill is normally cheaper per month than relying on nic salts or pre-filled pods. The up-front cost of a decent sub-ohm kit is higher, but it pays back quickly for a daily vaper.

Value is not only about price. It is also about how much you need to buy to keep going. A bottle that lasts a week or more, flavours that do not burn out your coils quickly, and a profile you actually like enough to finish are all part of the picture. A cheap liquid you dislike is poor value, and a flavour you enjoy that costs a little more per ml can be better value overall. That is why the sensible approach is to buy a single bottle first if you have not tried the flavour, then stock up if you like it.

Some practical ways to keep costs down:

• Order enough to reach free UK delivery on orders over £20
• Look out for multibuy and bundle offers on the site
• Prime coils properly and keep wattage in range to extend their life
• Keep unopened bottles in a cool, dark place so none go to waste

Prices change, so check the current price and any offers on the product page before ordering. Orders placed before 4pm are normally dispatched the same day.

How Devil Teeth compares with other 50ml shortfills

Fruit and mint is a crowded category in the UK, and fair comparisons depend on what you value: sweetness, coolness, price, or the range of other flavours from the same brand. Here is how Devil Teeth sits against the type of liquid you will see next to it.

• Against other Nasty 50ml flavours: the Nasty range includes fruit, candy and dessert-leaning profiles such as Trap Queen, Fat Boy, Slow Blow, Green Apple, ASAP Grape and Wicked Haze. Devil Teeth is lighter and cooler than the sweeter candy and dessert options, so it suits someone who finds those too rich.
• Against Doozy Vape Co and IVG shortfills: these brands have wide ranges with a lot of ice and sweet fruit blends. Their pricing is broadly similar for 50ml, and the choice usually comes down to which specific flavour you prefer. If you want a more intense menthol hit, some of their ice-heavy options are stronger than Devil Teeth.
• Against Dr Frost and similar ice-focused brands: these lean much harder on cooling. If you want a very chilled vape, they will feel cooler. Devil Teeth is gentler and more fruit-led.
• Against Bar Juice 5000 and other disposable-style flavour shortfills: these aim to copy the taste of popular disposable flavours, and many of their blends are sweeter and more candy-like. Devil Teeth tends to read as more of a straightforward fruit and mint combination.
• Against nic salt equivalents: Nasty also makes Devil Teeth in a 10ml nic salt format. That is more suitable for low-power pod kits and mouth-to-lung vaping, but it costs far more per ml. Choose by device, not by flavour alone.

Where Devil Teeth is arguably weaker than rivals is complexity. It is a clean, uncomplicated flavour, so someone who wants layered notes, cream, or a sharp tang will probably find other bottles more interesting. Its strengths are that it is easy to live with, it is not cloying, and it comes at a low price per ml from a brand that is easy to find in UK shops.

Brand loyalty matters less than you might think. Most vapers who try a few shortfills end up with two or three they rotate between, so Devil Teeth works well as one of a small rotation rather than your only liquid. If you are unsure, buy one bottle of Devil Teeth and one contrasting flavour, such as a berry or a menthol, and see which you reach for.

Remember that taste is subjective. No review, including this one, can tell you exactly how a liquid will taste in your tank, at your wattage, with your coil.
