Overview: Slush Brew Purple Mix 10ml at 12mg

Slush Brew by Ohm Brew in Purple Mix is a 10ml bottle of nicotine e-liquid sold at a 12mg/ml strength. It is a refill liquid, not a disposable and not a pre-filled pod, so you pour it into your own refillable tank or pod kit, choose how much you vape, and top up when you need to. The 'Slush' part of the name describes the intended drinking-style experience: a cold, frosted finish laid over a blend of purple-toned fruit. The 'Purple Mix' variant name points to a combination of dark berry and grape-style notes rather than a single fruit, which is the usual way purple flavours are built in UK e-liquid.

This guide is written for UK vapers who want a straight explanation of what the liquid is, how it behaves in typical kit, and whether it suits their setup. Where the exact formulation is not stated in the product name (the VG/PG split, for example), we say so rather than guess, and we point you to the bottle label, which is the authoritative source for ingredients, nicotine content and batch information.

Key facts at a glance

• Product: Slush Brew by Ohm Brew, Purple Mix
• Type: nicotine e-liquid (refill bottle)
• Bottle size: 10ml
• Nicotine strength: 12mg/ml, which works out at 120mg of nicotine across the full bottle
• UK limits: nicotine e-liquid is capped at 20mg/ml and sold in bottles of no more than 10ml, so this product sits at 60 per cent of the legal maximum strength
• Age restriction: 18+ only, with age checks applied to every order

Because this is a bottled liquid, performance depends heavily on the device you pair it with. A 10ml refill gives you roughly five fills of a standard 2ml pod or tank, and the nicotine level is one that many light-to-moderate smokers find comfortable in a mouth-to-lung setup. The rest of this page covers flavour, device matching, coils, charging, strength choice, troubleshooting and value, with plain comparisons to the alternatives you are likely weighing up alongside it.

What 10ml and 12mg mean in practice

Numbers on an e-liquid label are easy to skim past, but they decide how the product behaves, so it is worth spelling out the arithmetic. A strength of 12mg/ml means every millilitre of liquid contains 12 milligrams of nicotine. Across a 10ml bottle that is 120mg in total. A standard 2ml tank or pod filled to the line holds about 24mg of nicotine, which is the working figure to keep in mind when you compare this liquid with other formats.

For context, the old UK disposable vape was limited to 20mg/ml of nicotine in a 2ml pre-filled reservoir, which meant up to 40mg in a single device. Single-use vapes have since been banned from sale in Great Britain (the ban took effect on 1 June 2025), and the 20mg/ml ceiling still applies to refillable e-liquid and to the pods that go in reusable kits. A 12mg/ml bottle therefore gives you a middle-of-the-range option rather than the top-strength end of the shelf. If you are moving from a disposable that was at the 20mg limit, 12mg will feel noticeably softer, and you may need to vape slightly more often or step up to a higher strength.

Other legal and labelling points worth knowing

• Nicotine-containing e-liquid in the UK must be sold in refill bottles of 10ml or less, and tanks on vape devices are limited to 2ml capacity.
• Products have to be notified to the MHRA before they can be sold, and bottles carry a child-resistant, tamper-evident closure plus a health warning on the label.
• The label lists the ingredients, the nicotine content in mg/ml, and a batch number. Keep the batch number if you ever need to raise a query about a bottle.
• The VG/PG ratio is not given in the product name. Bottles in this style of range are generally formulated as a balanced mix suitable for pod kits and standard tanks, but check the label on the bottle you receive for the exact split rather than relying on a general rule.

This guide assumes a standard freebase nicotine formulation at 12mg/ml. If the label on your bottle states that it uses nicotine salts, treat 12mg/ml as a gentler strength than it would be in freebase and read the strength guidance section below with that in mind.

Flavour profile: what Purple Mix tastes like

Purple flavours in vaping are usually built on three pillars: a dark, slightly tart berry layer (blackcurrant or blueberry), a sweeter grape or grape-soda layer, and a cooling agent that gives the whole thing a chilled edge. Slush Brew Purple Mix follows that structure. The 'Mix' in the name tells you to expect a blend rather than a single fruit, and the 'Slush' branding tells you the cooling element is meant to be prominent, closer to a frozen drink than to a menthol cigarette.

What to expect on the inhale

• A juicy, rounded purple-fruit note up front, with a berry tartness that stops the sweetness feeling flat.
• A smooth transition into a sweeter grape-leaning middle, which is where most of the dessert-drink character sits.
• A frosted, slush-style cooling effect that builds through the inhale and lingers on the tongue.

What to expect on the exhale

• A clean, cool finish with the berry notes returning as an aftertaste.
• A lightly sweet residue that is typical of fruit-and-ice liquids, so it is worth rinsing your mouth with water between long sessions if you are sensitive to sweetness.

Flavour perception varies with device and power. At lower wattage in a mouth-to-lung pod, the fruit tends to sit slightly forward and the cooling is gentle. At the top of the recommended wattage range, the cooling intensifies, the sweetness becomes more pronounced, and the berry tartness can be partly masked. If you find the cooling too strong, drop your power by a couple of watts or use an airflow setting that is slightly more closed to concentrate the flavour without adding heat.

It is also worth being honest about the limits of a flavour description. Taste is subjective, and what reads as 'grape' to one person reads as 'blackcurrant' to another. If you have not tried a purple-fruit liquid before, treat this as a sweet-and-cool fruit profile rather than a sharp, sour one, and choose it if that sounds like what you want from an all-day flavour. People who prefer tobacco, nut, dessert-custard or sharp citrus profiles will probably find other variants in the range or in other brands a better match.

Performance and vapour delivery

With a bottled liquid, 'puff count' is not a fixed number the way it is on a disposable, because it depends on how you draw, what device you use and how much liquid your coil vaporises per second. The more useful figures are how many fills you get from a bottle and how long those fills last.

Working numbers for a 10ml bottle

• A 2ml pod or tank filled close to the line takes about 1.8 to 2ml, so a 10ml bottle gives you around five fills.
• At a typical mouth-to-lung pace, a 2ml fill lasts a moderate vaper roughly one to two days, so a bottle usually lasts somewhere between four and ten days.
• Heavier users who vape continuously can get through a bottle in two to three days, while very light or social vapers may stretch it to a couple of weeks.

These are planning estimates, not guarantees. The number of draws per fill varies enormously, and a few hundred puffs per 2ml is a reasonable ballpark for a mouth-to-lung coil at 12 to 18 watts, but your own counting method (and your own draw length) will move that figure up or down.

Throat hit and vapour

At 12mg/ml in freebase form, the throat hit is moderate. It is noticeable enough for someone transitioning from cigarettes to feel they are getting something that resembles a smoking sensation, but it is not as sharp as a 18mg or 20mg freebase liquid. Vapour production in a mouth-to-lung device is modest and tidy. If you use this liquid in a high-power, large-airflow setup, you will get more vapour and a stronger throat hit than the label strength suggests, because you are drawing more liquid per puff. That is why we recommend keeping this particular bottle in low-to-mid-power kit.

Consistency across a tank

Fruit-and-ice liquids are sweet, and sweet liquids leave more residue on a coil. Expect the flavour to stay steady for the first couple of tanks per coil and then begin to flatten as the coil darkens. That is a normal sign the coil is wearing, not a fault with the liquid, and it is covered in more detail in the troubleshooting section.

Design and build quality of the bottle

A refill bottle has a simple job: hold the liquid safely, let you fill a small tank without spilling, and keep the contents stable until you use them. The packaging on a 10ml nicotine e-liquid in the UK is shaped by regulation as much as by design, so a lot of what you see on this bottle is standard across the category.

What you should find on the bottle

• 10ml plastic bottle with a squeezable body. Soft plastic is usual for this size because it lets you control the flow into a small fill port.
• Narrow, long nozzle so the liquid can be directed into pod and tank fill holes, which are often only a few millimetres wide.
• Child-resistant, tamper-evident cap. You need to push down and turn, and a breakable ring confirms the bottle has not been opened before. This is a legal requirement for nicotine liquids, not an optional extra.
• Label panel showing the product name, flavour, nicotine strength, ingredients, batch number and warnings.

Build-quality checks worth making on arrival

• Check that the tamper-evident ring is intact before you open the bottle.
• Squeeze gently with the cap on. A bottle that weeps from the body or seam should be reported rather than used.
• Look at the colour of the liquid. Fruit liquids with a purple profile can range from pale to deeply tinted, and the tone can darken a little with time or light exposure. A moderate change is normal, but extreme cloudiness or separation is worth querying.
• Confirm the nicotine strength on the label reads 12mg/ml and matches your order.

Store the bottle upright, in a cool place away from direct sunlight, and out of reach of children and pets. Nicotine liquid is a poison risk if swallowed or absorbed through skin in quantity, so wipe up spills immediately and wash your hands after filling. Light and heat degrade flavour and nicotine over time, so a cupboard is a better home for spare bottles than a windowsill or a car glove box.

Compatible devices, coils and mesh technology

The liquid does not contain a coil, but the coil in your device determines how the liquid tastes and how it delivers nicotine, so matching the two is the most important decision you will make with a 12mg bottle. This strength is designed with mouth-to-lung (MTL) vaping in mind, which is the style that feels closest to drawing on a cigarette: a tight draw, a small amount of vapour pulled into the mouth, then inhaled.

Recommended coil range

• Resistance: roughly 0.8 to 1.2 ohm for a standard MTL coil, or higher for very low-power pod systems.
• Power: around 10 to 20 watts, depending on the coil rating printed on the coil head or pod.
• Airflow: tight to medium. Fully open airflow is better suited to sub-ohm devices running much lower nicotine strengths.

Regular wire coils versus mesh coils

Traditional round-wire coils are wound around a cotton wick and heat from a small contact area. They are widely available, inexpensive and well suited to MTL. Mesh coils use a flat sheet of perforated metal with a much larger heating area, which usually produces more vapour and a smoother, fuller flavour. Because mesh coils vaporise more liquid per second, a 12mg liquid in a high-power mesh setup delivers more nicotine per draw than the label strength implies. If you use a mesh MTL coil, keep to the lower end of the power range printed on the coil and consider whether you really need the stronger delivery.

Pod kits and refillable tanks

Refillable pod kits that accept a bottle through a side or top fill port are an easy match. Many pod systems also use ceramic or cotton-wicked pre-made coils that are rated for freebase nicotine up to about 20mg/ml, but always check the coil or pod packaging for any nicotine strength or VG/PG guidance given by the manufacturer. Some pod devices work better with thinner liquid and may struggle with very thick liquids, while the reverse is true for sub-ohm tanks, which prefer higher VG.

If you are not sure whether a device suits this liquid, compare the coil resistance and the recommended wattage on its packaging against the ranges above. When those line up, you can expect a satisfying result. When they do not, you will often be happier choosing a different strength or a different kit.

Battery, charging and recycling

An e-liquid bottle has no battery, so there is nothing in the bottle to charge. What matters is the battery in the device you pair it with, because that is what governs how long you can vape between charges and how consistently the coil heats.

Matching liquid usage to device battery size

• Small pod kits (about 400 to 700mAh): typically last a day for a moderate vaper, with a charge time of roughly an hour to ninety minutes over USB-C.
• Larger pen-style kits (about 800 to 1500mAh): can last a day or more and suit people who vape through the evening.
• Box mods and bigger kits (2000mAh and above): are usually aimed at sub-ohm vaping and are more than you need for a 12mg MTL liquid.

As a rough guide, a 10ml bottle at a moderate usage rate is going to outlast several battery charges, so you will charge your device multiple times for each bottle you get through. Most modern devices charge by USB-C, and a basic 5V phone charger is sufficient.

Safe charging habits

• Use the cable supplied with your device or a reputable replacement.
• Do not leave a device charging overnight on a bed, sofa or other soft surface.
• Do not charge a device that is damaged, swollen, hot to the touch or has exposed wiring.
• Unplug when the charge indicator shows full.

Recycling empty bottles and old devices

Lithium batteries are a fire risk in household bins and waste trucks, so they should never go in general rubbish. Vape devices and batteries belong in the WEEE (waste electrical and electronic equipment) stream. In the UK, shops that sell vape devices are required to take back waste vapes, and your local council recycling centre normally has a small electricals bank where you can leave them. Search for a vape recycling drop-off point near you through your council's website or the national recycling locator. Empty e-liquid bottles can usually go into household plastic recycling once they are completely empty and capped, though local rules vary, so check your council's guidance.

Nicotine strength guidance: is 12mg right for you?

Nicotine strength is the single most useful choice you make when buying e-liquid, and it is easy to get wrong in either direction. Too weak and you end up chain-vaping to compensate. Too strong and you feel dizzy, nauseous or jittery. The table below is general guidance, not medical advice, and anyone who is unsure should ask their GP, pharmacist or local stop-smoking service.

Rough strength guide for freebase MTL liquid

• 0 to 3mg/ml: very low or no nicotine, for people who have largely stopped using it or who vape out of habit.
• 6mg/ml: light nicotine, suited to people who smoked only a few cigarettes a day or who are close to finishing a taper.
• 12mg/ml (this bottle): medium nicotine, commonly chosen by people who smoked about 10 to 15 cigarettes a day, or by those stepping down from a higher strength.
• 18 to 20mg/ml: higher nicotine, often used by heavier smokers at the start of a switch. 20mg/ml is the UK legal maximum.

How to decide

• If you smoke roughly a pack a day or wake up needing a cigarette within minutes, 12mg may feel a little light in a low-power pod and you may find yourself topping up more often. Consider 18mg or a nicotine salt as an alternative.
• If you smoke about half a pack a day or less, 12mg is a sensible starting point in a standard MTL device.
• If you are already vaping and want to cut back, 12mg is a logical step down from 18 or 20mg, followed by 6mg and then 3mg when you are ready.
• If you feel lightheaded, shaky or queasy after vaping, you are probably taking too much nicotine. Reduce the strength, vape less often or choose a lower-power setup.

It is worth knowing the difference between freebase nicotine and nicotine salts. Freebase delivers a sharper throat hit and is used at lower strengths in the 3 to 20mg/ml range. Nicotine salts feel smoother at higher strengths, which is why they are commonly sold at 10mg/ml and 20mg/ml. If the label on your bottle describes this liquid as a salt, 12mg/ml would be noticeably more satisfying than the same number in freebase, so you should adjust accordingly.

Nicotine is addictive, and vaping is not risk-free. It is intended for adult smokers who want an alternative to tobacco. If you do not smoke, you do not need to start.

Who this liquid is for and who should look elsewhere

Slush Brew Purple Mix at 12mg suits a fairly specific set of vapers, and it is more useful to say so plainly than to pretend it fits everyone.

It is a good fit if you:

• Are an adult smoker or existing vaper who wants a medium-strength fruit-and-ice liquid for an everyday refillable kit.
• Use a mouth-to-lung pod or tank with a coil in roughly the 0.8 to 1.2 ohm range.
• Prefer sweet, cold, drink-style flavours over tobacco, dessert or menthol profiles.
• Want a 10ml bottle that is easy to carry, easy to fill from and straightforward to store.
• Have moved away from disposables since the ban and are looking for a refillable alternative that keeps the same kind of fruity profile.

You may want to look elsewhere if you:

• Smoke heavily and need a stronger delivery. A higher-strength freebase liquid or a nicotine salt at 10 to 20mg/ml may suit you better.
• Use a sub-ohm tank with big airflow. A 12mg liquid is too strong for most sub-ohm devices, and a lower-strength, higher-VG shortfill or 3mg/6mg bottle is more appropriate.
• Do not like sweetness or cooling agents. Slush-style liquids are intentionally cold and sweet.
• Have a device with a pre-filled, non-refillable cartridge. This liquid is a bottled refill and will not work with sealed cartridges.
• Are pregnant, have a heart condition, or have been advised by a clinician to avoid nicotine. Speak to a healthcare professional before using any nicotine product.

Who should not buy this product at all

This product is sold only to people aged 18 or over. If you are under 18, or buying on behalf of someone who is, do not purchase it. Non-smokers should not start using nicotine products. If you are curious about vaping but have never smoked, this is not a product for you.

A fair summary is that this is a mainstream, medium-strength, fruit-and-ice refill designed for MTL kit. It does not try to cover every taste or every device, and it is better judged on whether it does that one job well than on whether it replaces everything else on your shelf.

How to use: filling, priming and storing

Using a bottled e-liquid is simple once you have done it a couple of times, but the first few fills are where most mistakes happen. These steps apply to the majority of refillable pod kits and tanks. Always read your own device's manual too, because fill-port design differs between brands.

Step by step

• Wash and dry your hands, and work over a table or tray in case of drips.
• Switch off the device or remove the pod or tank so that it cannot fire accidentally.
• Open the fill port. On many pods this is a silicone bung on the side; on tanks it is often a sliding top cap.
• Remove the bottle cap by pushing down and twisting. Squeeze the bottle gently so liquid runs down the inside wall of the fill hole rather than straight into the centre tube, which reduces air bubbles and flooding.
• Fill to just below the maximum line. Do not overfill, because the liquid needs a little airspace to avoid leaking.
• Close the port, wipe away any spilled liquid, and recap the bottle.
• Wait. This is the step people skip.

Priming the coil

A new coil contains dry cotton, and if you fire it before it is saturated it will burn and taste harsh. After filling, wait at least five to ten minutes (longer for thick liquids or mesh coils) so the wick can soak through. A few gentle draws without pressing the fire button can help pull liquid into the coil before you begin vaping properly.

Settings and technique

• Start at the lower end of your coil's recommended wattage and increase in small steps.
• Take slow, steady draws of two to four seconds rather than short sharp pulls.
• Leave 20 to 30 seconds between draws on a new coil so it can re-wick.

Storage between uses

Keep the bottle capped, upright and in a cool, dark place. Because it is a fruit-and-ice liquid, it may develop a slightly deeper colour over weeks, which is a normal result of ingredients reacting with light and air. If you store a refillable device with liquid in it for a long time, it can leak, so empty and clean it if you are going to leave it unused for more than a few days.

Troubleshooting common problems

Most problems that appear to be caused by a liquid are really caused by the coil, the fill technique or the power setting. The list below covers the issues UK vapers report most often with sweet fruit-and-ice liquids and what usually fixes them.

Burnt or harsh taste

• The coil may be dry. Refill the tank, wait a few minutes and take gentle draws before firing.
• The wattage may be too high for the coil. Drop it by two to three watts.
• Sweet liquids can darken coils over time. If the taste has gone dull or acrid after several refills, replace the coil.

Gurgling, spitting or bubbling

• Excess condensation inside the airflow tube is the usual cause. Wipe the mouthpiece and tank airway with a tissue.
• Check that the coil is seated properly and the tank is tightened fully.

Leaking from the device

• Check that all seals and silicone bungs are in place and undamaged.
• Do not overfill. Leave a small air gap.
• Store the device upright and avoid carrying it in a warm pocket for long periods.

Flavour seems weak or has disappeared

• This may be 'vaper's tongue', a temporary loss of taste sensitivity caused by using the same sweet flavour repeatedly. Switch to a different flavour for a day or two, drink water, and the effect usually fades.
• If a new bottle tastes weaker than expected, make sure the coil is primed and the airflow is not set too wide.

Throat hit too strong or too weak

• Too strong: lower the power, close the airflow slightly, or change to a lower-strength bottle.
• Too weak: raise the power in small steps, or consider a higher nicotine strength or a nicotine salt.

Dry hits

A dry hit feels hot and papery and means the wick is not getting enough liquid. Chain-vaping with a thick liquid is a typical cause. Pause between draws, make sure the tank is filled, and use a coil that is suited to the thickness of the liquid you are using.

If something looks genuinely wrong with the bottle itself, such as an unusual smell, a broken seal or a leaking seam, stop using it, keep the packaging and batch number, and contact the retailer.

Value for money and honest comparisons

Value in vaping comes down to three questions: what does it cost per millilitre, how long does that millilitre last in your device, and does it give you what you actually want from the experience? Because current pricing and offers can change, check the product listing for the current price. What follows is how to think about the value of a 10ml bottle against the alternatives.

Cost per millilitre

Divide the price by ten to get the cost per ml. As a worked example, a bottle priced at £4 works out at 40p per ml, and five 2ml fills would cost 80p each. Compare that figure with other formats rather than looking at bottle price alone.

Against other formats

• Disposables: disposables are no longer sold legally in Great Britain. When they were available they typically cost several pounds for around 2ml of liquid, and then went in the bin. A refillable setup with bottled liquid is cheaper per millilitre once you own the kit, and it generates far less electronic waste.
• Pre-filled pod cartridges: these are convenient and tidy, but a pack of cartridges usually costs more per ml than a bottle, and you are limited to the flavours the pod maker offers.
• Shortfills (50ml or 100ml bottles with room for nicotine shots): better value per ml and often used in sub-ohm kit, but they require mixing in a nicotine shot and are aimed at a different style of vaping. A 12mg MTL liquid is the more convenient choice if you vape at low power.
• Other 10ml fruit-ice ranges: there are plenty of comparable liquids in the UK market, and the differences are mostly down to flavour accuracy and personal taste. Price differences among 10ml bottles are often small, so choose on flavour rather than on a few pence.
• Nicotine salt 10ml bottles: these usually come in 10mg/ml and 20mg/ml strengths and deliver nicotine more smoothly at higher strengths, which suits very low-power pod kits and heavier smokers. If you want a smoother hit at a higher strength, a salt will probably serve you better than this freebase 12mg bottle. If you prefer a noticeable throat hit, freebase at 12mg is the more traditional route.

Where this liquid is strongest, and where it is not

It is a sensible choice if you want a medium-strength purple-fruit-and-ice flavour in a convenient bottle for a mouth-to-lung kit. It is not the right choice for heavy smokers who need 18 to 20mg/ml, for sub-ohm users, or for anyone who dislikes cooling agents. Buying one bottle to try, rather than a multipack, is a low-risk way to find out whether the flavour fits your taste before you commit to more.
