Slush Brew by Ohm Brew 10ml Blue Mix 12mg: overview

Slush Brew by Ohm Brew in the 10ml Blue Mix flavour is a bottled e-liquid from the Slush range, supplied at a nicotine strength of 12mg/ml. It is a refill product rather than a finished device, which means you pour it into a refillable pod, tank or pen-style kit that you already own. If you are moving over from pre-filled pods, or from the single-use vapes that were taken off UK shelves in June 2025, this is the type of product that sits underneath most of the refillable market: a small bottle, a defined flavour, and a nicotine strength that you choose yourself rather than one that is fixed by the device.

The 10ml bottle size is set by UK rules rather than by marketing. Nicotine-containing e-liquid can only be sold in containers of up to 10ml, and the strength is capped at 20mg/ml. At 12mg/ml, Slush Brew Blue Mix sits at a medium level, comfortably below that ceiling. One full bottle therefore holds 120mg of nicotine in total (12mg per ml multiplied by 10ml), which is a handy figure to keep in mind when you compare it with other formats or work out how quickly you are getting through your supply.

The name tells you what to expect from the style. Slush-type flavours are built around a cold, crushed-ice impression layered over fruit, and blue-themed mixes in the vape world usually lean on a blue raspberry style fruit note with a sweet, slightly tart edge. We go into the profile in detail further down, but it is worth saying at the start that taste is subjective and that this page reflects our reading of the product, not a laboratory analysis. The label on your bottle is always the final word on ingredients, VG/PG ratio and batch details.

Key facts at a glance:

• Range: Slush Brew by Ohm Brew
• Flavour: Blue Mix, a blue fruit and ice style
• Bottle size: 10ml
• Nicotine strength: 12mg/ml (1.2%)
• Total nicotine per bottle: 120mg
• Format: refill e-liquid for compatible pod, tank and pen-style devices
• Age restriction: 18+ only, and not for non-smokers

The rest of this guide covers how the liquid behaves in practice, which hardware suits it, whether 12mg is the right strength for you, and how to deal with the usual problems that crop up with sweet, fruit-forward liquids. It is written for UK adults who already smoke or vape and want straightforward information before they buy.

Vapour production, throat hit and how long a bottle lasts

E-liquid does not have a puff count in the way a disposable does, because the number of puffs you get depends entirely on the device, the coil and your own habits. What we can do is give you sensible ranges based on how much liquid different setups typically use. These are estimates, not guarantees, but they are far more useful than a printed number that nobody can verify.

A 10ml bottle is made up of 10 millilitres of liquid. In a low-power mouth-to-lung (MTL) pod or pen kit, a single draw uses somewhere in the region of 0.01 to 0.02ml, so a bottle can stretch to a few hundred up to roughly a thousand puffs. In a looser, restricted direct-to-lung (RDL) setup at higher wattage, each puff can use 0.05ml or more, which brings a bottle down to a couple of hundred puffs. Heavy vapers on powerful hardware can empty 10ml in a day or two, while a light MTL user might make a bottle last the best part of a week.

Vapour volume and throat hit are linked to the strength and the VG/PG balance as much as to the flavour itself:

• Throat hit: at 12mg/ml you should expect a noticeable but not harsh throat hit in an MTL device. If you are using freebase nicotine, the hit is firmer than nicotine salts at the same strength; if the bottle is a salt, it will feel smoother.
• Vapour volume: a higher VG share produces thicker clouds, while a higher PG share gives a sharper hit and better flavour transfer. Check the label for the ratio on your bottle.
• Cooling effect: the slush character comes from a cooling agent, and it tends to feel stronger at lower power settings and fade slightly as the coil runs hotter.

It is also worth separating two ideas that often get muddled. A fixed bottle volume tells you how much liquid you have, while the nicotine you absorb depends on how many puffs you take and at what strength. With 12mg/ml, the same ten puffs deliver far more nicotine than they would at 3mg/ml, so heavy chain-vaping on a medium strength tends to leave people feeling lightheaded or queasy. If that happens, put the device down and take a break rather than pushing through.

As a practical guide, many MTL users report that a 10ml bottle at this strength lasts between three days and a week. If you find yourself finishing one in a day, it is a sign that your power is too high, your coil is too open, or your strength is too low for your needs.

Blue Mix flavour profile

Blue Mix is a fruit-and-ice flavour, and the Slush branding is a good guide to how it is meant to taste. The idea is to mimic a frozen, crushed-ice drink: a sweet blue fruit note up front, a little tartness in the middle, and a cold, clean finish that sits on the tongue after you exhale. We read the fruit as a blue raspberry style candy note rather than a realistic berry, which is how most blue-themed e-liquids are put together.

Here is how we would describe the stages of a puff:

• Inhale: sweet, bright fruit with a slightly sugary edge, similar to blue sweets or a fizzy drink concentrate.
• Mid-draw: a gentle tartness that stops the sweetness from becoming flat, plus the first sense of chill.
• Exhale: a cool, icy finish that lingers briefly. It is closer to the cold of a frozen drink than the sharp bite of a menthol cigarette.

Flavour intensity depends on your setup. In a tight MTL pod with a modest coil, the fruit tends to come through clearly and the cooling stays moderate. In a looser draw with a higher wattage, the sweetness can feel more diffused and the ice effect weaker, because the heat reduces the impact of the cooling agent. If you find the flavour muted, drop the power by a watt or two before assuming the liquid is at fault.

A few honest caveats are worth mentioning. Sweet fruit liquids carry more sweetener than tobacco or plain menthol flavours, and that has two effects. First, the coil tends to darken sooner, which can dull the flavour as the days go on. Second, anyone who dislikes very sweet liquids may find Blue Mix cloying after a long session. If you prefer dry, subtle or tobacco-led tastes, this is not going to be your flavour.

Cooling agents also vary in how people perceive them. Some find the chill refreshing, while others find it tickles the throat. If you are sensitive to menthol-type sensations, treat the Slush name as a warning that there will be a cold element, and start with a few puffs before committing to a full tank.

Finally, give it a short rest after filling. A couple of minutes for the coil to saturate, plus a gentle shake of the bottle beforehand, helps the flavour come through evenly from the first puff rather than showing up thin and then ramping up.

Bottle design, packaging and build quality

Because this is an e-liquid, the design discussion is about the bottle and packaging, not about a device body. A 10ml nicotine e-liquid in the UK has to meet a set of packaging rules, and a well-made bottle makes the everyday job of refilling cleaner and safer.

What to look for on the bottle:

• Child-resistant closure: nicotine e-liquid must come with a child-resistant cap, which usually needs a push-and-turn action. It can be fiddly, but it is there for a reason, so do not defeat it by leaving the bottle open.
• Tamper-evident seal: the cap should have a ring or seal that breaks on first opening. If it looks already broken when delivered, contact the retailer.
• Fine nozzle: 10ml bottles generally come with a narrow tip to suit pod and tank fill ports. Squeeze gently, because a hard squeeze on a flexible bottle can send a spurt of liquid over the edge.
• Health warning and label: the bottle should show the nicotine warning, strength, ingredients, batch number and a contact point for the supplier.

Plastic 10ml bottles are the norm and have good practical reasons behind them: they are light, they do not shatter in a bag or pocket, and the softer walls help you control the flow. The downside is that plastic is not completely impervious over a long time, so the liquid should be kept out of strong sunlight and away from heat, which can darken it and alter the taste.

On build quality, you are really judging three things. The cap should fit tightly without leaking along the thread. The nozzle should not drip after you stop squeezing. And the label should stay legible after a bit of handling, because you will want to check the strength and batch number later on. If anything is faulty on arrival, take a photo and contact the shop promptly.

Environmentally, empty bottles are generally recyclable as household plastic once they are rinsed and the cap removed, but rules differ between local councils, so check what yours accepts. Do not pour leftover liquid down the sink in bulk; let a small residue dry or wipe it out with a paper towel before recycling.

Keep the bottle upright, in its box if you have one, and well away from children and pets. Even a small amount of nicotine liquid can be harmful if swallowed or if it gets on bare skin, so wipe up spills straight away and wash your hands after filling.

Choosing a device: battery, charging and compatibility

Slush Brew Blue Mix has no battery of its own, so the battery question is really about the hardware you choose to pair it with. The right device makes a big difference to how the liquid tastes and how long a bottle lasts, so it deserves a little thought before you fill anything.

For a 12mg liquid, the usual fit is a compact refillable pod kit or a pen-style device. Typical examples in the UK market have batteries somewhere between 400mAh and 1000mAh, charge over USB-C, and are rated for low to medium power. As a rule of thumb, a 500 to 700mAh pod kit will comfortably last a day for a moderate MTL user, while a 1000mAh device may stretch to a day and a half. These figures vary with your puff frequency, so treat them as a starting point.

Things worth checking when you pick a device:

• Fill port and capacity: a 2ml tank or pod is common in UK kits, so one 10ml bottle will fill it about five times.
• Power range: for this strength you want a device that works well at roughly 8 to 20 watts, or one that auto-regulates to a safe output.
• Airflow control: adjustable airflow lets you tighten the draw to suit MTL and pushes the throat hit and flavour in the right direction.
• Coil availability: make sure replacement coils are easy to buy, because you will need them every one to two weeks.

Charging guidelines are straightforward but worth following carefully. Use the cable supplied with the device, or a reputable USB-C cable, and a standard phone-style charger rather than a high-wattage fast charger unless the manufacturer says otherwise. Do not charge on a bed, sofa or other soft surface, and do not leave a device charging unattended overnight. If a battery becomes hot, swollen or damaged, stop using it.

At the end of life, a device and its internal battery are electrical waste. They should not go in household bins. Retailers that sell vaping products are generally required to take back waste devices and batteries, and household recycling centres also run drop-off points. Many local councils list the nearest location on their website, and returning devices this way reduces the fire risk in refuse lorries and recycling plants.

If you already own a device, check its manual for the recommended resistance and wattage range before you settle on this flavour. A mismatch between device and liquid is the single most common reason people feel disappointed with an otherwise decent e-liquid.

Coils and mesh: what works with this e-liquid

The coil is where the liquid actually turns into vapour, and for a 12mg fruit-and-ice flavour the choice of coil has a larger effect on your experience than most people expect. The key number is resistance, measured in ohms, and the key decision is whether you want a tight mouth-to-lung draw or a looser airy one.

For 12mg/ml, a mouth-to-lung coil is the natural pairing. In practice that means resistances of around 0.8 to 1.2 ohms in a tank, or the 0.6 to 1.0 ohm coils found in many pod systems that are designed for nicotine salts. At these resistances and at modest wattage, a medium-strength liquid delivers a satisfying hit without needing huge amounts of power.

Coil types you will come across:

• Round wire (Kanthal or stainless steel): the traditional style. Predictable, cheap and widely available, with a slightly warmer, more rounded flavour.
• Mesh coils: a flat woven sheet that increases the heated surface area. Mesh generally gives quicker ramp-up and stronger flavour, which suits a fruit-and-ice mix, though lower-resistance mesh can use liquid faster.
• Ceramic coils: found in some pod kits. They are valued for clean flavour and consistency, but they can respond poorly to very sweet liquids if they are flooded, so do not over-fill.

It is worth being straightforward about a mismatch to avoid. Sub-ohm tanks with coils below 0.5 ohms are built for much lower nicotine strengths, typically 3mg/ml or 6mg/ml, and run at 40 watts or more. Using a 12mg liquid in that kind of setup would deliver a huge amount of nicotine per puff and would almost certainly be harsh and unpleasant. Match the coil to the liquid, not the other way round.

Coil life depends on the sweetness of your liquid and how hard you push the device. With a sweet profile like Blue Mix, expect somewhere between one and two weeks per coil under normal use. Signs that a coil is nearing the end include a burnt or flat taste, gurgling, a muted flavour even on fresh liquid, and a noticeable drop in vapour.

When fitting a new coil, prime it by dripping a few drops directly onto the cotton through the coil's side holes, fill the tank, and wait five to ten minutes before the first puff. Skipping this step is the quickest way to burn a new coil and ruin the flavour before you have enjoyed it.

12mg nicotine strength guidance

Choosing a nicotine strength is the decision with the biggest impact on whether an e-liquid works for you. At 12mg/ml (1.2%), Slush Brew Blue Mix is a medium strength. It is a common step for people coming off roughly ten to fifteen cigarettes a day, or for vapers who find lower strengths leave them reaching for the device constantly.

Here is a rough map of how strengths are usually used. It is general information, not medical advice, and everyone responds differently.

• 0 to 3mg/ml: very light, typically for sub-ohm vaping or for people who have nearly stopped nicotine altogether.
• 6mg/ml: a low-to-medium level, often used in higher-powered setups or by lighter smokers.
• 12mg/ml: medium. Suited to MTL pod and pen devices, and to people who smoked a moderate amount.
• 18 to 20mg/ml: the top of the UK range. Usually nicotine salts for very heavy smokers in low-power pod devices.

The type of nicotine matters as much as the number. Freebase nicotine gives a sharper throat hit that becomes noticeably harsh as the strength rises, which is why 12mg freebase feels firm and why most people stop at around 12 to 18mg in that form. Nicotine salts are smoother and are typically sold at 10 to 20mg/ml for low-power pod kits. Check your bottle label to see which you have, because the same number on the label can feel very different in the throat.

Some practical pointers if you are unsure:

• If you feel dizzy, queasy, or get a pounding heart after vaping, the strength or the amount is too high for you at that moment.
• If you keep craving a cigarette within an hour or so, your strength may be too low or your power too weak.
• If you are stepping down gradually, drop in small increments and give each one a couple of weeks.

Remember that at 12mg/ml a full 10ml bottle contains 120mg of nicotine. Nicotine is addictive and toxic in large quantities, so keep the product away from children and pets, and never leave an open bottle within reach.

If you do not currently smoke or vape, you should not start. Vaping is intended as a tool for adult smokers who want to switch, not as a lifestyle product for people who have never used nicotine. If you are trying to quit, the NHS offers free local stop smoking services that can combine support with products, and a conversation with a pharmacist or GP is a sensible step.

Who this e-liquid suits, and who should skip it

Every e-liquid is a match for some people and a poor fit for others. Being clear about which camp you are in saves money and avoids disappointment, so here is an honest look at who Slush Brew Blue Mix at 12mg is likely to work for.

It is likely to suit you if:

• You are an adult smoker or existing vaper who wants a medium strength for a mouth-to-lung device.
• You enjoy sweet, fruit-forward flavours with a cold finish rather than tobacco or dry profiles.
• You already own a refillable pod or pen kit and want a flavour to run through it.
• You like the cost control and flexibility of refilling rather than buying pre-filled pods or discarded devices.
• You want a 10ml format that is easy to carry and cheap to replace if it is lost.

You should probably look elsewhere if:

• You have never smoked or vaped. Nicotine is addictive and there is no benefit in starting.
• You are under 18. It is illegal to sell nicotine products to anyone under 18 in the UK, and age checks apply on delivery.
• You use a sub-ohm tank at high wattage. 12mg is too strong for that style and a lower strength would be a better match.
• You dislike sweet or cooling flavours. The Slush character is the whole point, and you may find it tiring.
• You are pregnant, breastfeeding, or have a heart condition. Speak to your GP or pharmacist before using any nicotine product.

There is also a middle group worth mentioning: people who are cutting down on nicotine. If your goal is to reduce gradually, 12mg is a sensible mid-point to step down from 18 or 20mg, and you can move to 6mg and then 3mg over time. If you are already at the point of vaping 3mg or 6mg comfortably, going up to 12mg would be a step in the wrong direction.

For people who switch between flavours, Blue Mix works well as an all-day option for some and as an occasional treat for others. Many vapers keep two or three bottles on the go so they can alternate, which reduces flavour fatigue. If you find that sweet liquids lose their appeal after a few days, a rotation of one fruit-and-ice flavour, one plain menthol and one dessert or tobacco profile is a practical approach.

How to fill, prime and use it

Using a bottled e-liquid is simple once you have done it a couple of times, but there are a few steps that make the difference between a clean, flavourful experience and a leaky, gurgling one. Always read the manual that came with your device first, because fill methods vary between top-fill, side-fill and cartridge-style pods.

Step-by-step:

• Wash your hands and clear a flat surface. Spills of nicotine liquid on skin should be washed off straight away.
• Shake the bottle gently to mix the flavour evenly, then twist and lift the child-resistant cap.
• Remove the pod or open the tank according to your device instructions. Keep it upright where possible.
• Insert the nozzle into the fill port and squeeze slowly. Stop below the maximum fill line, and do not cover the central airflow tube.
• Close the port and reseat the pod or tank, then wipe away any liquid from the outside.
• Wait five to ten minutes so the cotton can soak, especially with a fresh coil.
• Take a couple of gentle puffs without pressing the fire button to draw liquid into the cotton, then begin normal use.

Once you start vaping, a few habits improve the experience. Take slow, steady draws of two to four seconds instead of short, sharp ones; that gives the coil time to vaporise the liquid properly and reduces spitting. Avoid chain-vaping, since the coil does not get time to re-wet and it can burn. Keep the device roughly upright when not in use so the liquid does not flood the airflow.

Storage is easy but worth getting right. Keep the bottle in a cool, dry place away from direct sunlight and radiators. Unopened, e-liquid typically stays in good condition for a year or more, while a bottle that has been opened and exposed to air is best used within a few months. Keep it out of sight and reach of children, and never decant it into drinks bottles or unmarked containers.

Legal reminders for UK users: you must be 18 or over to buy and use nicotine products, you should not vape where it is prohibited by venue policy, and you should never give e-liquid to anyone under 18. When you are travelling, check the rules for your route, because some countries restrict or ban nicotine e-liquids.

Finally, take care to match the strength and flavour on the bottle you are filling with what you intend to use, because mistakes are easy to make if several bottles are open at once. One bottle on the table at a time is a simple, effective rule.

Troubleshooting common problems

Most problems with fruit-and-ice e-liquids come down to the coil, the fill method or the power setting, and not to the liquid itself. Here are the issues we hear about most often and what usually fixes them.

• Burnt or harsh taste: usually a dry or worn coil. Prime a new coil properly, do not chain-vape, and replace the coil if the taste is still off after a fresh fill. Sweet liquids darken coils faster than unflavoured ones.
• Weak or muted flavour: check the coil age first. If it is more than about two weeks old, swap it. Also try lowering the power, as heat can flatten the cooling effect.
• Gurgling or spitting: too much liquid in the chamber, or condensation in the airflow. Dry the mouthpiece, blow gently through the device to clear the airway, and avoid overfilling.
• Leaking from the pod or tank: check that the seals are seated, the fill port is closed, and you have not overfilled. Store the device upright and avoid squeezing the tank when fitting it.
• Throat too sharp: either the strength is too high for you, the power is too high, or the device is a loose-draw type not suited to 12mg. Try a tighter draw, lower power or a lower strength.
• Not enough nicotine satisfaction: raise the power slightly, tighten the airflow, or consider whether you need a different nicotine type such as a salt. Do not simply keep puffing harder.
• Dry hits (no vapour, hot air): the cotton is not getting enough liquid. Stop at once, re-prime the coil, wait several minutes and try again at lower power.
• Liquid seems cloudy or darker: some darkening is normal with age and exposure to light. If there is a clear change in smell, taste or consistency, do not use it and contact the retailer.

If you have tried these fixes and something still seems wrong, it helps to swap one variable at a time. Fit a fresh coil, fill with the same bottle, and test at a lower setting. If the problem disappears, the issue was the coil. If it persists with a known good coil, test the bottle in a second compatible device if you have one.

For any physical problem with the bottle itself, such as a loose cap, a cracked body, a damaged seal or a leaking label, stop using it, photograph the fault, and contact the shop with your order number. Do not try to force a stuck child-resistant cap, as that can lead to a spill.

When disposing of dead coils and empty pods, treat them as electrical or mixed waste according to your local council. Many vape shops and recycling centres accept them, and it is better than putting them in a household bin.

Value for money

Judging value on an e-liquid is about more than the price on the page. You need to think about how long a bottle lasts, what it costs to run, and what you would otherwise be spending on a similar nicotine intake. We have not put a fixed price in this guide because it can change, so we will show you the maths and let you plug in the current price.

Start with cost per millilitre, which is simply the bottle price divided by ten. Then compare it with the cost per millilitre of other formats. Then consider how many millilitres you realistically use each day, which for most MTL vapers is somewhere between 1.5 and 4ml. Multiply the two numbers and you have a daily figure that you can compare with what you would spend on cigarettes or pre-filled pods.

A few points specific to this product:

• One bottle fills a typical 2ml pod or tank about five times. That is a useful way to see it as five fills rather than a single purchase.
• Running costs include coils. A coil costs a few pounds and lasts one to two weeks with a sweet flavour, so factor in about one or two coil changes per bottle for a moderate user.
• Refilling avoids single-use waste. You are replacing a bottle and a coil, not an entire device, which tends to be cheaper over a month.
• 12mg is efficient for MTL. A medium strength in a low-power device uses less liquid per unit of nicotine than a low strength in a high-power one.

Where bottled e-liquid can cost more than expected is when it is used in the wrong hardware. If you vape a 12mg liquid at high power or in an open airflow setup, you will burn through it quickly and probably feel unwell, so the cost per useful puff rises. The remedy is to match the device, coil and strength as described above.

Compared with buying a new kit, a single bottle is a low-risk purchase. If you try Blue Mix and decide the flavour is not for you, you have lost the price of one 10ml bottle, not a full device. For people who are curious about the Slush range but unsure about sweet and cold flavours, a 10ml is a sensible way to try before committing to larger sizes.

Finally, check for multibuy deals, which can lower the cost per bottle if you know you will use the flavour. Just remember to store spare bottles in a cool, dark place so they stay in good condition until you need them.

How it compares with other options

It is fair to ask how Slush Brew Blue Mix at 12mg stacks up against the alternatives a UK vaper might consider. We have not run controlled side-by-side tests against every competitor, so we will not claim that one tastes better than another. What we can do is explain the practical differences between categories and let you decide.

Against single-use vapes. Disposable vapes were banned from sale in the UK in June 2025. Before that, they were limited to 20mg/ml and a 2ml liquid capacity. Refillable kits with bottled e-liquid are now the main route for people who want a convenient format, and they typically work out cheaper and generate less electrical waste than throwing away a device every few days.

Against pre-filled pods. Closed pod systems are simple to use because you just clip in a new pod. The cost per millilitre is usually higher and the flavour choice limited to what the manufacturer makes. Bottled liquid gives you far more variety and control over strength, though you have to put in the effort of filling.

Against other 10ml fruit-and-ice ranges. There are plenty of established brands that make blue raspberry, berry ice and slush-style flavours in the same bottle size. The differences usually come down to a few things:

• VG/PG ratio: affects vapour volume, throat hit and how well the liquid wicks in small coils.
• Sweetener level: more sweetener means richer taste but faster coil build-up.
• Cooling intensity: ranges from a light chill to a sharp icy blast.
• Nicotine type: freebase and salt versions feel different at the same strength.

Against 50ml shortfills. Large shortfill bottles are sold with no nicotine and are intended for sub-ohm devices, with nicotine shots added if wanted. They offer more millilitres per pound but the resulting strength is usually only 3mg/ml or lower, and the process of mixing is fussy. A ready-made 12mg 10ml bottle is a better fit if you want a medium strength in a pod or MTL tank without mixing.

Where this product is weaker: it is not a budget bulk option, it is not suitable for sub-ohm hardware, and it will not please anyone who dislikes sweet flavours. Where it is stronger: it is simple, convenient, and pitched at a strength and format that suits mainstream MTL setups.

If you want to compare properly, buy one bottle and run it for a few days in the same device you normally use. Take notes on flavour, throat hit and how long the bottle lasts. Your own results are worth more than any review, including ours.
