Overview of Slush Brew Red Mix 12mg

Slush Brew by Ohm Brew Red Mix is a 10ml bottle of nicotine e-liquid in a red-fruit, slush-style flavour. This listing is for the 12mg/ml strength, which works out at 1.2% nicotine by volume and 120mg of nicotine across the whole bottle. It comes in the standard 10ml format used for nicotine e-liquid in the UK, and it is meant to be poured into a refillable tank, a refillable pod or a similar device rather than used on its own.

The name tells you most of what you need to know. Ohm Brew is the maker, Slush Brew is the range, and Red Mix is the individual flavour: a blend of red-toned fruit with the cold, crushed-ice character that slush drinks are known for. Slush-style liquids sit in the same wider family as fruit-and-ice flavours, but they tend to aim for a softer, rounder chill rather than a sharp menthol blast. If you have been vaping fruit-and-ice flavours and want to move to something you can refill and control, this is the sort of profile that makes the switch easy.

Here are the quick facts at a glance.

• Product type: nicotine e-liquid, 10ml bottle
• Flavour: Red Mix, a red-fruit slush profile
• Nicotine: 12mg/ml (1.2%), which is 120mg of nicotine per full bottle
• Intended devices: refillable pod kits and mouth-to-lung (MTL) or restricted direct-to-lung tanks
• Not included: no battery, coil, pod or tank, as this is liquid only
• Age restriction: 18+ only, and photo ID may be requested on delivery

The 10ml size is not a choice made for convenience. UK rules limit nicotine e-liquid bottles to 10ml and cap nicotine strength at 20mg/ml, so you will not find a larger nicotine bottle of this type from a UK retailer. Bigger bottles such as 50ml shortfills are sold without nicotine, and you add separate nicotine shots to them yourself. A 10ml bottle will fill a typical 2ml pod or tank about five times, which gives you a rough idea of how long it should last once you know your own habits.

This page walks through what the liquid is like to use, which devices suit it, how to choose between nicotine strengths, how to fix common problems, and how it compares with other options at a similar price. The aim is to give you enough detail to decide whether it fits your setup, without overselling it.

Flavour Profile: What to Expect from Red Mix

Red Mix is named after a colour family rather than a single fruit, so the realistic expectation is a layered red-fruit taste rather than one dominant note. In blends like this, the front of the inhale is usually sweet and juicy, carrying berry and stone-fruit tones, while the back of the inhale brings a slight tartness that stops the sweetness from feeling heavy. The slush element then arrives as a cool finish that builds on the exhale instead of hitting the throat straight away.

Taste is personal and device settings change it a lot, so treat the following as a guide rather than a promise of exact fruit identification. Some vapers pick out strawberry or raspberry; others notice cherry or a watermelon-leaning sweetness. If you are curious, the easiest way to judge a mixed-fruit liquid is to vape it at a moderate setting, exhale slowly through the nose, and note which fruit your brain names first.

• Inhale: sweet red fruit, rounded rather than sharp
• Mid-vape: a gentle tartness that keeps the sweetness in check
• Exhale: a cool, slushy finish that fades over a few seconds
• Aftertaste: light sweetness with a faint chill, not syrupy or sticky

How power and temperature change the flavour. Cooling and fruit notes both respond to heat. At a lower wattage, the vapour is cooler and the fruit layers stay distinct, with the slush chill coming through clearly. Push the power up and the vapour warms, the sweetness becomes flatter and more dominant, and the chill softens. If Red Mix tastes muted or overly sweet, turn the power down a few watts before assuming the liquid is at fault.

How 12mg affects the taste. Nicotine itself has a peppery, slightly bitter edge. At 12mg/ml in a freebase liquid you will notice a moderate throat hit, noticeably more than at 3mg or 6mg. In a fruit flavour, that throat hit tends to blend into the cool finish, which is one reason fruit-and-ice styles are popular at mid strengths. If the throat hit feels too sharp, the fix is usually a lower strength or a lower power setting rather than a different flavour.

Keeping the flavour fresh. Sweet liquids can cause palate fatigue, sometimes called vaper's tongue, where a flavour you enjoyed yesterday suddenly tastes dull. Drinking water, avoiding chain vaping, and rotating to a different flavour for a day or two usually fixes it. Sweetened liquids also leave more residue on coils, so a coil that has started to taste burnt or flat may simply be due a change. We cover that in the troubleshooting section below.

Performance and Vapour Delivery

Because Red Mix is a liquid rather than a complete device, performance depends on the device you pair it with. What the liquid contributes is its nicotine strength, its thickness and its flavour load. Those three things shape how much vapour you see, how it feels in the throat, and how satisfying each draw is.

Nicotine delivery. At 12mg/ml, each millilitre carries 12mg of nicotine. A 2ml tank filled with Red Mix holds 24mg of nicotine in total. For comparison, a typical single-use vape of the kind sold before the UK banned them held 2ml at 20mg/ml, which is 40mg. The ban on single-use vapes came into force on 1 June 2025, which is why many former disposable users now look at refillable systems. Per millilitre, 12mg freebase is a gentler strength than 20mg nicotine salt, but the freebase form gives a firmer throat hit.

Vapour volume. Standard 10ml nicotine e-liquids are generally balanced blends of vegetable glycerine (VG) and propylene glycol (PG). A higher-VG liquid makes bigger clouds and a smoother feel, while a higher-PG liquid gives a sharper throat hit and carries flavour more crisply. Always check the VG/PG split printed on the bottle or listed on the product page, since that is the authoritative figure. In general, 10ml freebase bottles are formulated for pod systems and low-power MTL tanks, so expect modest clouds and a tight, flavour-focused draw rather than a large plume.

Typical performance with common setups.

• Refillable pod kit, 1.0 to 1.2 ohm coil, around 10 to 15W: a tight draw, good flavour, light to moderate vapour, and a gentle throat hit at 12mg
• MTL tank with a 0.8 to 1.0 ohm coil, around 12 to 18W: fuller flavour and slightly more vapour, with a firmer throat hit
• Restricted direct-to-lung tank with a 0.6 to 0.8 ohm mesh coil, around 15 to 25W: more vapour, but 12mg freebase can feel harsh here, so many people drop to 6mg or 3mg for this style

How long a bottle lasts. Consumption depends on device, power and habits. A light user on a pod kit might use 1 to 2ml a day, which makes a 10ml bottle last five to ten days. A heavier MTL user might go through 3 to 4ml a day, so the bottle lasts closer to three days. These figures are rough estimates, and your own use is the only reliable measure.

If the liquid seems to disappear faster than expected, the usual causes are an overly high wattage, a coil that is flooding, or a leak at the pod seal rather than the liquid itself. The troubleshooting section lists how to check each one.

Design and Build Quality

With e-liquid, design means the bottle, the cap and the label, because those are what you handle every time you refill. The Slush Brew range follows the standard 10ml format used across the UK market, which means a small plastic bottle with a narrow dropper-style nozzle and a tamper-evident, child-resistant cap.

Bottle and nozzle. Ten-millilitre nicotine bottles are normally made from soft, squeezable plastic so you can control the flow. The nozzle is thin enough to fit into most pod fill ports and tank top-fill holes. If your device has a very narrow fill port, tilt the bottle slowly and squeeze gently, because a fast squeeze can cause overflow and spills.

Child-resistant cap. UK regulations require nicotine e-liquid bottles to have child-resistant and tamper-evident closures. The cap on this bottle is designed to need a push-and-turn action. It can feel stiff at first, which is deliberate. After you have finished filling, always close the cap fully and store the bottle out of reach of children and pets.

Labelling. You should find the following information on or with the packaging, which is a useful checklist when your delivery arrives:

• the product name, flavour and bottle volume (10ml)
• the nicotine strength (12mg/ml) and a health warning about nicotine
• a batch number and best-before or use-by date
• an ingredients list, usually showing PG, VG, flavourings and nicotine
• the manufacturer or importer details

If anything is missing, contact us before you use the bottle.

Packaging on delivery. Nicotine e-liquid is sensitive to heat, light and rough handling, so a sealed bottle in intact packaging is what you should receive. Check that the tamper seal under the cap is unbroken. A cracked bottle, loose cap or sticky residue on the outside suggests a problem in transit, and you should report it with a photo so it can be put right.

Colour and look. The Slush Brew range is presented in a bright, drinks-inspired style, in keeping with the slush idea. This is only branding, but it is worth remembering that colourful packaging can attract children, which is another reason to store the bottle securely and keep it away from where it could be mistaken for a drink or sweet.

Durability. A sealed bottle stored upright in a cool, dark place usually keeps its flavour for many months. Once opened, the liquid slowly oxidises, so most vapers aim to finish a bottle within a few months for the best flavour and consistency.

Battery and Charging: Matching the Liquid to Your Device

Slush Brew Red Mix has no battery of its own, so there is nothing in the bottle to charge. The battery and charging question is really about the device you put it in. A good match between liquid and battery makes the vape more consistent and avoids frustration, so it is worth a few minutes of thought.

Battery capacity guidance. A 12mg freebase liquid in an MTL or restricted setup draws relatively little power. As a rough guide for typical devices:

• Slim pod kits with 400 to 700mAh batteries: suitable for light use, normally needing a top-up charge once a day
• Mid-size pod kits with 800 to 1,200mAh batteries: comfortable for a full day for most people at 10 to 15W
• Larger MTL or restricted DTL mods with 1,500 to 3,000mAh internal or 18650 batteries: a day or more between charges when running modest wattage

These are indicative ranges, as actual battery life depends on wattage, puff length and how often you vape. A higher wattage drains the battery faster, and a 0.6 ohm mesh coil will consume more than a 1.0 ohm pod coil.

Charging habits. Most modern pod kits charge by USB-C. A few practical points keep the battery healthy and safe:

• Use the cable supplied with the device, or a good-quality USB-C cable from a known maker
• Use a standard wall adaptor or a computer port, not a fast-charge brick unless the device says it supports one
• Never leave a charging device unattended or charge it overnight on a soft surface such as a bed or sofa
• Stop using and recycle any device with a swollen, hot or damaged battery

Spare and removable batteries. If your device uses a removable 18650 cell, carry and store spares in a plastic case, never loose in a pocket with coins or keys. Use only batteries from reputable brands and check the amp rating suits your device.

Recycling worn-out batteries and devices. Vape devices and lithium batteries should never go in household bins or kerbside recycling. Under UK waste electrical rules, shops that sell vaping products are expected to take back old devices, and most household waste recycling centres have a battery and small electricals bay. Searching by postcode on a national recycling locator will show your closest drop-off point.

Coils, Mesh and Wicking: What Works with 12mg Freebase

The coil is the part of your device that heats the liquid, and it has a bigger influence on how Red Mix tastes and feels than most people expect. Matching the coil to the liquid strength is the single most useful adjustment you can make.

Coil types in plain terms. Most modern coils are one of two designs. A traditional round-wire coil is a wound length of resistance wire around a cotton wick, and it tends to produce a warmer, tighter vape with strong flavour. A mesh coil uses a flat sheet of metal mesh in contact with cotton, which spreads heat over a larger area. Mesh coils usually give a faster ramp-up, more even flavour and more vapour, which is why they are common in newer pods and tanks.

Resistance and power. Resistance is measured in ohms. Higher-resistance coils need less power and give a cooler, tighter draw. Lower-resistance coils need more power and produce more vapour and heat. As a reference for a 12mg freebase liquid:

• 1.0 to 1.5 ohm: well matched to 12mg, with a pod-style tight draw, typically 8 to 15W
• 0.8 to 1.0 ohm: still comfortable at 12mg, with a slightly airier draw, typically 12 to 20W
• 0.5 to 0.7 ohm mesh: better suited to lower strengths such as 3mg or 6mg, since 12mg can be harsh at the higher power these coils want

Wicking. Nearly all coils use organic cotton. A balanced VG/PG liquid wicks well in most pod and tank coils. Very thick liquids can struggle in small-hole pod coils, and very thin liquids can leak. If the bottle is balanced, as many 10ml freebase ranges are, wicking is rarely an issue as long as you prime the coil properly.

Coil lifespan with sweet liquids. Fruit and slush flavours contain sweeteners and flavour compounds that leave a residue on the coil as they heat. A typical coil lasts one to three weeks, depending on use. Signs it is time for a change include a flat or burnt taste, a gurgling sound, reduced vapour and a rough throat hit.

Compatibility. Most refillable pods and tanks sold in the UK accept 10ml freebase liquid without any modification. Always check the manufacturer's guidance on the maximum VG ratio and recommended wattage for your coil, as ignoring those limits is the most common cause of dry hits and early coil failure.

Nicotine Strength Guidance

Choosing the right strength is the most important decision for a comfortable switch. Too low and you will keep vaping more to get what you need. Too high and the throat hit becomes unpleasant. This listing is for 12mg/ml, which is a mid-to-upper freebase strength.

Typical freebase ladder. Freebase liquids usually come in 3mg, 6mg, 12mg and 18mg/ml. A common starting point is based on how many cigarettes a day someone smoked before switching. The following is general guidance only and is not medical advice, as individual needs vary a lot:

• Fewer than 10 cigarettes a day: often starts at 3mg to 6mg
• 10 to 20 cigarettes a day: often starts at 12mg, which makes this bottle a reasonable place to begin
• More than 20 cigarettes a day: often starts at 12mg to 18mg in an MTL setup

Freebase compared with nicotine salt. Nicotine salt liquids, usually sold at 10mg and 20mg/ml, are smoother at higher strengths and deliver nicotine more quickly. A 12mg freebase liquid has a firmer throat hit but a more gradual feel. If you are coming from a 20mg disposable or pod and want a similar level of satisfaction, a 12mg freebase may feel a little lighter, and a 18mg freebase or a nicotine-salt strength might feel closer. If you find 20mg too strong, 12mg freebase can be a good step down.

The UK limit. The legal maximum nicotine strength for e-liquids and pre-filled pods sold in the UK is 20mg/ml. The same cap applied to the single-use vapes sold before they were banned. Anything above 20mg/ml is not legal to sell in the UK, so be wary of unregulated sellers claiming otherwise.

Signs that your strength is wrong.

• Too low: you vape constantly, feel restless soon after, or have cravings that return quickly
• Too high: you feel dizzy, nauseous or jittery, get a harsh throat hit or a racing heart

If you get symptoms of too much nicotine, stop vaping, drink water, get some fresh air and consider a lower strength next time. If the symptoms are severe or do not pass, seek medical advice.

Reducing over time. Many vapers lower their strength gradually, moving from 12mg to 6mg and then 3mg, and some eventually move to 0mg. If you want to do this, consider buying a lower strength of the same flavour so you do not have to change taste at the same time. If you are unsure, a stop-smoking adviser or pharmacist can help you choose.

Who Slush Brew Red Mix Suits

No liquid fits everyone. Here is an honest look at who is likely to enjoy Red Mix at 12mg and who would be better served by something else.

Likely to suit:

• Adult smokers moving to vaping: a mid-strength freebase with a fruity, approachable flavour can be an easier first step than a tobacco or menthol profile for some people
• Former disposable users: if you were using fruit-and-ice single-use vapes before the ban, this style will feel familiar and costs less per millilitre on a refillable device
• Pod kit owners: 10ml bottles and 12mg strength fit the kind of 1.0 ohm pod coils most beginner kits use
• People who like cool, sweet flavours: if you enjoy iced drinks and fruit sweets, the slush profile is designed for you
• Vapers who like to rotate flavours: 10ml bottles let you try a flavour without committing to a 50ml bottle

May not suit:

• Non-smokers and under-18s: nicotine is addictive, and it is illegal to sell nicotine vaping products to anyone under 18 in the UK. Do not buy this if you do not already use nicotine
• People who dislike sweet or cooling flavours: if you prefer tobacco, nutty or dessert profiles, this will not feel natural
• Large-cloud, high-power users: 12mg freebase at 40W and above is likely to feel harsh, and a 50ml shortfill with nicotine shots is a better fit
• Anyone sensitive to nicotine: consider a lower strength, or talk to a pharmacist about other options
• Pregnant or breastfeeding women, or people with heart conditions: nicotine products should be discussed with a medical professional first

A note on responsible use. Vaping is widely regarded in UK public health guidance as far less harmful than smoking, which is why it is promoted as a route away from cigarettes for adult smokers. That does not make it risk-free, and it is not intended for anyone who does not already smoke or vape. If your goal is to quit nicotine altogether, ask your pharmacist or local stop-smoking service about support.

Experience level. Beginners can use this liquid, provided they have the right device and strength. Experienced vapers will recognise the 10ml freebase format and probably already have opinions on their favourite power and coil combinations. Either way, start at a modest wattage and adjust slowly rather than jumping to maximum settings.

How to Use It: Filling, Priming and Vaping

A new bottle of e-liquid and a new coil need a small amount of preparation to work properly. Skipping the steps below is the most common reason a good liquid gets a bad first impression.

Step by step.

• 1. Shake the bottle gently. This mixes any ingredients that have settled during transit and storage.
• 2. Check your device is switched off or the pod is removed. This avoids accidental firing while your hands are wet.
• 3. Open the fill port. On a pod, this is usually a small silicone plug. On a tank, it is a sliding or screw-off top cap.
• 4. Fill slowly to the max line. Aim the nozzle at the side wall rather than straight into the central air tube. Never fill above the marked line.
• 5. Close the port and bottle. Wipe away any drips, since liquid on the outside of a device can leak into the electronics.
• 6. Wait five to ten minutes before the first puff. This lets the liquid soak into the cotton so you do not get a dry hit.
• 7. Take a few gentle draws without firing. This pulls liquid across the wick before the coil heats up.

Settings to start with. Begin at the lower end of the wattage range recommended on the coil. For a 1.0 ohm pod coil, 10 to 12W is a sensible start. Increase in 1 to 2W steps until the flavour is full without tasting hot or burnt.

Draw technique. Mouth-to-lung means drawing the vapour into your mouth first, pausing, then inhaling. A slow, steady draw of two to four seconds works best with a 12mg liquid. Long, hard pulls tend to flood the coil and produce a harsher throat hit.

Priming a new coil. Drip two or three drops straight onto the cotton before fitting the coil if the manufacturer allows it, then fill and wait. This is the single best way to avoid burning out a new coil in the first few puffs.

Cleaning up. If you spill liquid on your skin, wash it off with soap and water. If it gets in your eyes, rinse with plenty of water and seek advice. If it is swallowed, contact NHS 111 or a poison information service, or call 999 in an emergency.

Between sessions. Keep the device upright when it is not in use, lock it if it has a lock feature, and avoid leaving it in hot cars or direct sunlight. Heat thins the liquid and pushes it through the airflow, which causes leaks.

Troubleshooting Common Problems

Most problems with a refillable setup have a simple cause. The list below covers the issues vapers report most often and how to deal with them.

Dry or burnt taste.

• The coil may not have been primed, so wait longer after filling and take a few gentle draws before firing
• The wattage may be too high, so lower it by a few watts
• The liquid level may be too low, so refill before the wick is exposed
• The coil may simply be worn, in which case replace it

Weak or muted flavour.

• Palate fatigue is common with sweet flavours, so take a break or try a different flavour for a day
• A tired coil loses flavour long before it fails completely
• Very low power can give a cold, muted vape, so raise it slightly
• A blocked airflow or dirty drip tip will also dull the taste, so rinse and dry the tip

Gurgling or spitting. Condensation in the airway, or an overfilled tank, is the usual reason. Wipe the airway with a tissue, make sure you are not above the max fill line, and give the device a gentle blow-through to clear the channel.

Leaking.

• Check that the pod or tank is seated firmly and that the silicone seals are in place
• Do not overfill, as pressure changes can push liquid out
• Avoid carrying the device in a hot pocket or on a flight without emptying it first
• If the leak continues after a coil change, the pod may be damaged and need replacing

Throat hit too harsh. Lower the wattage, take shorter draws, or consider a lower nicotine strength. Higher temperature and longer draws increase harshness at 12mg.

Not enough nicotine satisfaction. Make sure your coil and wattage are matched, and give your body a few days to adjust. If you still feel you need more, a higher strength or a nicotine salt may be a better fit.

Device does not fire. Check the battery charge, make sure the pod is clicked in properly and that the contact points are clean. Wipe them with a dry cotton bud if there is residue.

When to stop and get help. If a device becomes hot, swells, smokes or smells of burning plastic, stop using it, move it to a safe place away from flammable items, and contact the manufacturer or the retailer for support.

Value for Money and How It Compares

Judging value on a 10ml bottle comes down to cost per millilitre, how long it lasts, and what you would otherwise be spending. The price shown on the product page changes from time to time, so the best way to compare is to divide the current price by 10 to get pence per millilitre, then compare that figure with alternatives.

Against single-use vapes. Single-use vapes are no longer sold legally in the UK, but many people who used them remember the cost. A typical 2ml single-use vape cost a few pounds for roughly 600 puffs. A 10ml bottle gives five times the liquid, so on a refillable device the running cost is usually lower, though you also need to budget for a device and replacement coils or pods.

Against pre-filled pods. Pre-filled pods are convenient, but each pod holds around 2ml, and you pay for the plastic and coil every time. Refilling from a 10ml bottle into a refillable pod removes the repeated pod cost, so over a month the saving can be real if you vape regularly.

Against other 10ml ranges. There are plenty of 10ml nicotine liquids at similar prices, including nicotine-salt ranges such as Elf Liq and Dinner Lady, and other freebase brands. Honest points of comparison:

• Nicotine-salt 10ml ranges: usually smoother at 10mg and 20mg and quicker to satisfy cravings, but not necessarily better for people who prefer a firmer throat hit
• Other freebase fruit-and-ice ranges: similar price points, so choice mostly comes down to which flavour you personally prefer, and no single range is universally ahead on taste
• Tobacco and dessert ranges: a different flavour family, so better if you dislike fruit and cooling

Against 50ml shortfills. A 50ml shortfill with nicotine shots is usually cheaper per millilitre, but it needs a sub-ohm style tank, extra bottles and a bit of mixing. It also produces much more vapour, which is not what every vaper wants. If you use a pod kit or an MTL tank, 10ml freebase is the simpler and better-matched choice.

Where Slush Brew sits. It is a mainstream 10ml freebase, priced in line with comparable ranges, with a clear flavour concept. It does not claim to outperform every rival, and it is a reasonable pick if the red-fruit slush profile appeals to you. If you want to test your preferences cheaply, buying a single bottle before stocking up is sensible.

UK Rules, Storage and Recycling

Buying and using nicotine e-liquid in the UK comes with a handful of rules and good-practice points worth knowing, especially if you are switching from another product.

What the rules say.

• Age: you must be 18 or over to buy nicotine vaping products, and retailers must verify age
• Bottle size: nicotine e-liquid bottles are limited to 10ml
• Nicotine strength: the maximum is 20mg/ml, which applied to disposables and applies to e-liquids and pre-filled pods
• Tank size: refillable tanks and pods are limited to 2ml
• Packaging: child-resistant, tamper-evident closures and a nicotine health warning are required
• Single-use vapes: banned from sale in the UK since 1 June 2025

These requirements come from the UK's tobacco and related products regulations and are the reason you see the 10ml format so widely. Product notification to the regulator is a legal requirement for the people who place these products on the market.

Safe storage. Nicotine is toxic if swallowed and can be absorbed through the skin. Store the bottle upright, with the cap fully closed, in a cool, dark place out of reach of children and pets. Do not decant liquid into drinks bottles or unlabelled containers. Keep it away from food and drink, and wash your hands after filling.

Travelling. Keep bottles and devices in a sealed bag. Air pressure changes can push liquid out of a full tank, so empty or close it before flying. Check airline rules on carrying lithium batteries and liquids before you travel.

Recycling empties. Empty e-liquid bottles still contain traces of nicotine, so they should not be treated like ordinary drinks bottles. Many local authorities do not accept them in kerbside recycling, so check your council's guidance. Some household waste recycling centres and vape shops take them in dedicated bins.

Recycling devices and batteries. Old vape devices, pods with electronics and batteries should be taken to a drop-off point rather than put in a household bin. Shops that sell vapes are expected to take back waste vaping equipment, and most household waste recycling centres have a small electricals and battery section. Used coils are small and metal, and are usually fine to dispose of with your device waste if the local centre allows.

Delivery and returns. We dispatch within the UK, and the delivery page shows current options and timeframes. Sealed, unopened items can generally be returned under UK distance-selling rules, while faulty or damaged goods are covered by your statutory rights. Opened e-liquid is a consumable, so contact us promptly if there is a fault so we can sort it out.
