Overview of Slush Brew Red Mix 10ml 18mg

Slush Brew by Ohm Brew in the Red Mix flavour is a 10ml bottle of nicotine e-liquid supplied at 18mg/ml, made for adult vapers in the UK who want a chilled red-fruit flavour in a refillable tank or pod kit. The product name tells you a good deal before you open the box. 'Slush' points towards a frozen fruit-drink style of flavour rather than a dessert, tobacco or sweet-shop profile, and 'Red Mix' points towards a blend of red fruit notes rather than a single named fruit. The 18mg strength sits at the upper end of the freebase nicotine range, which has a direct effect on which devices and which kinds of vaper it suits.

This page covers the practical questions a buyer usually has: what the flavour is likely to taste like, how many puffs you can expect from a bottle, what kind of coil and device to pair it with, whether 18mg is the right strength, how to fill and prime a tank, and what to do when something goes wrong. It is written from the product name, the 10ml and 18mg format, and the way this category of e-liquid behaves in real devices. Always read the label on your own bottle for the exact ingredient list, VG/PG ratio, batch code and expiry date, because those printed details take priority over anything general written here.

A few UK basics are worth stating at the start. Nicotine products are for adults aged 18 and over only. Under UK rules, nicotine e-liquid is sold in bottles of no more than 10ml, at a strength of no more than 20mg/ml, in child-resistant and tamper-evident packaging, and it has to be notified to the MHRA before it can be sold. This bottle sits inside those limits at 10ml and 18mg/ml. Separately, the sale of single-use disposable vapes has been banned in the UK since 1 June 2025, so a refillable setup fed from bottles like this one is now the usual route for adults who want to carry on vaping.

• Format: 10ml nicotine e-liquid bottle, not a disposable and not a device
• Strength: 18mg/ml, below the UK ceiling of 20mg/ml
• Flavour direction: chilled red-fruit slush
• Suits: mouth-to-lung tanks and pod kits that take higher-resistance coils
• Aimed at: adult smokers moving to vaping, and existing vapers who want a firmer freebase hit

Specifications at a glance

The list below separates what is fixed by the product name and UK law from what is typical for a bottle of this kind. Where a value depends on the batch or the exact formulation, the label on your bottle is the authority.

• Brand and range: Slush Brew by Ohm Brew
• Flavour: Red Mix
• Product type: nicotine e-liquid for refillable vape devices
• Bottle capacity: 10ml, which is the maximum size permitted for nicotine e-liquid in the UK
• Nicotine strength: 18mg/ml, which is 1.8% by volume
• Total nicotine in the bottle: 180mg (18mg/ml multiplied by 10ml)
• Nicotine form: 18mg is a freebase-style strength, whereas nicotine salt bottles are normally sold at 10mg and 20mg. Confirm on the label.
• VG/PG ratio: printed on the label. Ten-millilitre bottles at this strength are commonly balanced or PG-leaning so that they wick quickly in small coils.
• Suitable devices: mouth-to-lung tanks, refillable pod kits and pen-style kits using coils of roughly 0.8 to 1.8 ohm
• Typical power range: about 8W to 15W, always following the range printed on the coil
• Estimated yield: roughly 1,500 to 3,000 puffs per bottle, depending on device, power and puff length
• Minimum age to buy and use: 18

The puff estimate is a planning figure rather than a lab result. E-liquid is not rated by puff count the way a sealed disposable device used to be, because the amount you vape per puff changes with coil size, wattage, how long you draw and how well the cotton is wicking. A small, tight mouth-to-lung coil at low power uses far less liquid per puff than a large coil at high power, which is why the same bottle can last one person a week and another person three days.

The 180mg figure for total nicotine is worth noticing. It is the reason the bottle must be kept out of reach of children and pets, and the reason the child-resistant cap should always be closed properly after filling. Nicotine liquid is harmful if swallowed or if it gets on the skin in quantity, and any spill should be wiped up and the skin washed with soap and water.

Flavour profile: what Red Mix tastes like

Red Mix follows the slush idea: a blend of red fruit flavours sitting on top of a cold, crushed-ice style finish. Flavours in this family are usually built around a sweet red berry core, with a lighter sharp or tangy edge to stop the sweetness becoming heavy. Because the name says 'mix' rather than naming one fruit, expect a blended impression rather than a clear single-fruit note. Some vapers will pick out something close to a strawberry or raspberry sweetness, others will read it as a generic red fruit drink, and that variation is normal for blended profiles.

The slush element comes from a cooling agent. In most modern fruit-ice e-liquids that is a synthetic cooling compound rather than menthol, which creates a cold sensation on the tongue and throat without a strong mint taste. The cold is most noticeable on the exhale and at the back of the throat. If you dislike minty flavours but enjoy cold fruit, that distinction matters, and a profile like this is generally closer to a frozen fruit drink than to a menthol e-liquid.

At 18mg, the nicotine contributes its own character to the flavour. Freebase nicotine adds a peppery throat hit that sits underneath the fruit and cooling notes. Some people find this makes sweet flavours taste more rounded and less sugary, while others find it slightly harsh on a cold-flavoured liquid, because cooling agents and nicotine both stimulate the throat. If you find the combination too sharp, lower your wattage a little, take a slower draw, or consider a lower strength.

A few things change how the flavour comes across in practice:

• Wattage: lower power keeps the fruit notes cooler and cleaner; higher power warms the vapour and tends to push the sweetness forward while softening the cooling effect
• Coil type: mesh coils usually give a broader, more even flavour, while small round-wire coils can taste a little more concentrated
• Coil age: a fresh coil shows the cold fruit profile clearly, and as the coil gunks up the flavour turns flatter and sweeter, then eventually burnt
• Shaking and rest: a short shake and a few minutes of rest after filling helps the flavour mix evenly

Sweet fruit liquids can cause what vapers call vaper's tongue, where you temporarily stop tasting the flavour after vaping the same thing for days. If Red Mix seems to fade, swap to a different flavour family for a day, drink some water, and come back to it. That is a sensory effect rather than a fault in the bottle.

Performance and puff delivery

On performance, the useful questions are how much vapour you get, how hard the throat hit is and how long a bottle lasts. With an 18mg freebase liquid in a mouth-to-lung device, vapour production is moderate and the throat hit is noticeable. That is deliberate. The format is designed to feel closer to smoking a cigarette, with a tight draw, a firm hit and a modest cloud, rather than the large clouds associated with sub-ohm vaping.

For puff delivery, a reasonable working assumption for mouth-to-lung vaping is somewhere between 150 and 300 puffs per millilitre, which puts a 10ml bottle at roughly 1,500 to 3,000 puffs. Where you land in that range depends mostly on three things: coil resistance and size, power setting, and how long you hold each draw. A person taking short two-second draws on a 1.0 ohm pod coil will sit near the upper end, and a person taking long four-second draws on a larger mesh coil will sit near the lower end.

It helps to convert this into days. If you vape around 2ml a day, a bottle lasts about five days. At 3ml a day it lasts three to four days, and at 1ml a day it can stretch past a week and a half. Many smokers who are switching find they vape more in the first few weeks, then settle into a steadier pattern as the habit adjusts. If you are filling a pod kit with a small tank, keep a spare bottle at home so you are not caught out.

• Throat hit: medium to firm at 18mg, firmer at higher wattage
• Vapour: modest, suited to discreet use and to mouth-to-lung inhaling
• Draw style: slow, steady draws of two to four seconds, then a short pause before inhaling to the lungs if you inhale at all
• Consistency: stays steady as long as the coil is fresh and the tank is kept above the minimum fill level

Consistency is where sweet red fruit flavours can be demanding. Sugars and flavourings caramelise on the coil over time, and the liquid in the tank can taste different at the start of a fill than it does near the bottom. If the flavour drops off before the tank is empty, that usually points to a coil that has reached the end of its life rather than a weak bottle. Changing the coil is a faster test than blaming the liquid.

Finally, nicotine delivery is partly a function of puff frequency. If you find yourself taking constant puffs without feeling satisfied, the strength may be too low for your habit, and if you feel light-headed or queasy after a few puffs the strength is too high. The nicotine strength section below covers how to adjust.

Design, bottle and build quality

E-liquid does not have a build quality in the way a vape kit does, but the packaging still matters, because it affects how cleanly you can fill a tank and how safely the bottle can be stored. Ten-millilitre bottles in this category are normally soft plastic with a narrow nozzle that fits most refill ports, topped by a child-resistant cap that needs a firm squeeze-and-turn to open. The soft sides let you control the flow, and the narrow tip reduces the chance of overfilling the small pod and tank openings found on modern kits.

Under UK rules, the bottle and its carton must carry specific information. Expect to find the product name, nicotine strength, an ingredients list, the batch number, contact details for the supplier, a recommended storage instruction and the written health warning stating that the product contains nicotine, which is a highly addictive substance. If any of these are missing, damaged or unreadable, that is a reason to contact the retailer before you use the bottle.

Before the first use, run through a short inspection:

• The tamper-evident seal or ring should be intact when the bottle arrives
• The cap should turn and lock correctly, and the nozzle should not be cracked
• The bottle should not be leaking, sticky on the outside or noticeably dented
• The batch number on the bottle should match the one on the outer carton where both are printed
• The liquid should look clear, with a colour that fits a red-fruit flavour, and it should not contain visible particles

Storage makes a real difference to how the liquid ages. Keep the bottle upright in a cool, dark place away from direct sunlight, radiators and car glove boxes. Heat and light speed up oxidation, which darkens the liquid and can dull the flavour. A slightly deeper colour after a few weeks is common and does not mean the liquid is unsafe, but a strong chemical smell, separation that does not recombine after shaking, or visible cloudiness are signs to stop using it.

Check the expiry or use-by date printed on the bottle. Sealed and stored sensibly, e-liquid commonly keeps its flavour for a year or more, but the date on your own bottle is the one to follow. Once opened, treat it as a product you want to finish within a few months, especially in warm weather.

Finally, treat the bottle with the same care you would give any nicotine product at home: store it somewhere children and pets cannot reach, never decant it into a drinks bottle or an unlabelled container, and wipe any drips from the nozzle after each fill.

Coil and mesh compatibility

The coil is the part of your device that turns this liquid into vapour, and the coil you choose does more to shape your experience with an 18mg freebase liquid than almost any other factor. The general rule is simple. Higher-resistance coils, typically 0.8 to 1.8 ohm, suit 18mg freebase liquids. Low-resistance sub-ohm coils below 0.5 ohm are built for larger clouds and much more liquid per puff, and using 18mg in them delivers far more nicotine than most people want.

Common coil types you may meet include:

• Round-wire kanthal or stainless steel coils (1.0 to 1.8 ohm): the traditional mouth-to-lung option, giving a tight draw and a crisp throat hit, and generally working well with thinner, PG-leaning liquids
• Mesh coils (about 0.6 to 1.2 ohm in mouth-to-lung versions): a flat sheet of fine metal mesh with a large surface area, which heats quickly and tends to give a smoother, fuller flavour and longer life than a plain wire coil
• Ceramic coils: found in many pod systems and known for clean flavour, though they can be sensitive to being run dry and to very sweet liquids

Whatever coil you pick, the manufacturer prints a recommended wattage range on it. Starting at the lower end of that range is a sensible default for a cold fruit flavour, because lower power preserves the cooling effect and reduces the chance of burning the sweeteners. Raise the power in small steps only if the flavour feels thin.

Priming a new coil is the step most often skipped, and it is the main cause of an early burnt taste. After installing a coil, drip a few drops of the liquid directly onto the exposed cotton through the side holes, fill the tank or pod, and wait five to ten minutes before the first puff. Take the first few puffs without pressing the fire button hard, and let the cotton soak through. A coil that is vaped dry on its first use is often ruined within minutes.

Sweet red fruit liquids tend to build residue on coils faster than plain or tobacco flavours. Expect a coil to last somewhere around one to two weeks with regular use, and sometimes less if you vape at higher power or chain-vape. Signs that a coil is finished include a muted or sour taste, a burnt edge that does not clear after a refill, gurgling, and a rough throat hit. Rinsing the tank and fitting a new coil is the fix.

Compatibility notes in short: if your device is a pod kit with 1.0 ohm or higher coils, Red Mix at 18mg is a natural match. If your device is a sub-ohm tank, choose a lower-strength liquid designed for that style instead, such as a 3mg or 6mg bottle or a shortfill with a nicotine shot.

Battery and charging considerations

The bottle has no battery of its own, but the battery in the device you use it with affects how the liquid performs, so it is worth covering here. A mouth-to-lung kit working at about 10W draws modest power, and the numbers are easy to work out. A 1,000mAh battery stores roughly 3.7 watt-hours. At 10W, with some energy lost as heat in the circuitry, that is in the region of 300 to 400 three-second puffs per charge. A vaper using 2ml a day, at around 200 puffs per ml, takes roughly 400 puffs, so a 1,000mAh device is a one-charge-a-day kit for that user, and a 1,500mAh to 3,000mAh device or a removable-cell mod gives more headroom.

Good charging habits protect both the battery and your home:

• Use the cable supplied with the device, or a reputable replacement, and a standard USB charger or computer port rather than unbranded fast chargers
• Do not charge under a pillow, on a bed or sofa, or while you sleep, and keep it away from anything that can burn
• Unplug when the device is full, and stop using any cable that is frayed or any port that is loose
• Never leave a device in a hot car or in direct sun
• If a battery swells, overheats, smells odd or leaks, stop using it and take it to a recycling point rather than the bin

If your kit uses removable 18650 or similar cells, only use cells from a known supplier, check the wrap for tears, charge them in a proper external charger, and carry spares in a plastic case instead of loose in a pocket with keys or coins. Match the cell's continuous discharge rating to the device, since an under-rated cell is a safety problem rather than a performance one.

Disposal is where UK vapers sometimes go wrong. Vape devices, batteries and many pods count as waste electrical equipment, and putting them in household bins or kerbside recycling can cause fires in collection vehicles and waste plants. Instead, take them to a household waste recycling centre, or hand them in at a shop that sells vaping products, since UK retailers of electrical goods are expected to offer take-back. Recycle Your Electricals and your local council both list drop-off points by postcode. Remove the e-liquid from a tank before recycling it and do not pour leftover liquid down a drain. For empty nicotine bottles and cartons, follow your local council's guidance, since some treat them differently from ordinary plastic.

The disposable ban has made this more practical, because a refillable kit with replaceable coils produces far less electrical waste over a year than a stream of single-use devices. Keeping one device for months and recycling coils and batteries properly is better for your wallet and the environment than treating vapes as throwaway items.

Nicotine strength guidance for 18mg

Nicotine strength is the most personal decision you make with an e-liquid, and the right answer depends on how much you smoked, how you inhale and what device you use. UK law caps nicotine e-liquid at 20mg/ml. That is the same 20mg ceiling that applied to the old disposable vapes, and it still applies to every refill bottle and pod sold here. At 18mg/ml, this product sits just under the cap and should be seen as a high-strength option.

As a rough guide for freebase liquids in mouth-to-lung devices:

• 3mg: very light, for people close to being nicotine free or for sub-ohm vaping
• 6mg: light, a common step-down for people who have been vaping a while
• 12mg: medium, for moderate smokers or those who find 18mg too sharp
• 18mg: high, often chosen by people who smoked heavily, say 15 or more cigarettes a day, or who want a firm throat hit from a mouth-to-lung device

These are starting points rather than rules. Someone who smoked 20 a day but vapes with a large, efficient mesh coil may find 12mg plenty. Someone who smoked 10 a day but takes tiny puffs on a low-power pod may find 18mg works. If you are unsure, begin at a strength you can tolerate and adjust after a week.

Too much nicotine shows up as dizziness, nausea, headache, a racing heart, sweating or an unpleasantly harsh throat. If that happens, stop, drink water, get fresh air, and move to a lower strength. Too little nicotine shows up as cravings between puffs, chain-vaping and a feeling that the device is not satisfying. If you keep reaching for cigarettes, a stronger liquid or a different device may help.

It is also worth knowing the difference between freebase and nicotine salt. Freebase nicotine at 18mg gives a sharper throat hit at the same strength. Nicotine salt liquids are generally smoother and are sold at 10mg and 20mg for pod devices. A person who finds 18mg freebase too harsh may find a 10mg nicotine salt more comfortable, even though the numbers look lower, because the salt form is absorbed differently and feels gentler on the throat.

Vaping is not risk free, and these products are for adult smokers and existing vapers. If you do not smoke, there is no benefit in starting. If you are pregnant, breastfeeding or have a heart condition, speak to a pharmacist or doctor before using nicotine. Many people who want to stop smoking find that combining a stop-smoking service with a switch to vaping works well, and the NHS offers free local support.

Who Slush Brew Red Mix is for

This bottle is a fit for a clear group of adult users, and it is worth being honest about who it does not suit as well.

It makes sense if you are:

• An adult smoker who wants a mouth-to-lung experience that feels close to a cigarette, with a firm hit and a tight draw
• An existing vaper using a pod kit or a high-resistance tank who wants a cold fruit flavour at a higher strength
• Someone who prefers fruit and ice flavours to dessert, tobacco or sweet-shop profiles
• A person who likes small, discreet clouds and prefers a compact device that is easy to carry
• A user who wants a 10ml bottle at a modest outlay to test a flavour before buying larger quantities elsewhere

It is less suitable if you are:

• Under 18, or a non-smoker who does not use nicotine, as nicotine is addictive and these products are not intended for you
• A sub-ohm vaper using a low-resistance tank, where 18mg would be far too strong and the wrong VG/PG balance for the coil
• Sensitive to nicotine, pregnant or living with a heart condition, in which case you should speak to a healthcare professional first
• Looking for a sweet dessert, custard or tobacco flavour, as this is a cold red-fruit profile
• Someone who dislikes any cooling sensation in the throat, since the slush element will be noticeable

If you want the fruit-ice direction but find freebase at 18mg a little rough, there are two easy adjustments. One is to choose a lower strength, such as 12mg, in a similar flavour. The other is to move to a nicotine salt liquid, which gives a smoother hit at 10mg or 20mg and often suits small pod systems better.

There is also the question of experience. Beginners sometimes buy the highest strength out of caution about not getting enough nicotine, then find the throat hit unpleasant and give up on vaping. If you are new, remember that you can raise a strength later much more easily than you can recover from a bad first week. Buying a bottle at the strength that matches your smoking habit, and being willing to adjust, works better than guessing high.

How to use and fill your device

Filling a tank or pod is simple once you have done it a few times. These steps apply to most refillable mouth-to-lung devices, but your device manual takes priority if it differs.

• Prepare: wash and dry your hands, switch the device off or lock the fire button, and work on a flat surface with a tissue ready for drips
• Shake: give the bottle a gentle shake and wipe any residue from the nozzle
• Open the fill port: depending on the kit, this means sliding a side cover, pulling out a silicone bung or unscrewing the top cap
• Fill slowly: aim the nozzle at the side wall of the tank or pod rather than straight down the central chimney, and stop below the maximum fill line
• Close up: replace the bung or top cap, wipe any liquid from the outside of the device, and close the bottle's child-resistant cap firmly
• Wait: leave the device upright for five to ten minutes so the cotton can soak fully, especially with a new coil
• Start gently: take a few short, low-power puffs before settling into your normal pattern

Draw technique matters more than many beginners expect. For mouth-to-lung vaping, take the vapour into your mouth first with a slow two to four second draw, pause briefly, then inhale into your lungs if that is comfortable. Fast, hard pulls can pull liquid through the coil too quickly and create spitting or leaking. If you find the throat hit too sharp, lengthen the draw, take smaller puffs or turn the power down slightly.

Some practical habits keep your setup trouble-free:

• Refill before the tank is empty, since running low is the most common cause of dry hits and burnt coils
• Do not overfill, because excess liquid floods the airflow and leaks from the air holes
• Rinse the tank with warm water and dry it fully when you change flavours or coils
• Use only the coils recommended for your device, and note the date you fit each one
• Carry the device with the airflow closed or the tank mostly empty on flights or in hot weather, because pressure and heat can push liquid out

If you switch from another flavour to Red Mix in the same tank, a quick rinse prevents the old flavour from muddying the new one. Fruit and cooling flavours in particular can pick up aftertastes from tobacco or dessert liquids that were in the tank beforehand, so a clean start gives the fairest first impression of the liquid.

Troubleshooting common problems

Most problems with a refillable setup are about the coil, the wicking or the fill level, not about the liquid. Work through the list below before deciding a bottle is faulty.

• Burnt or acrid taste: the coil is dry, old or new and unprimed. Let a fresh coil soak, lower the wattage, refill the tank and, if the taste does not clear after a refill, fit a new coil.
• Flat or weak flavour: the coil is gunked up, the power is too low or you have vaper's tongue. Change the coil, step the power up a little and try a different flavour for a day.
• Throat hit too harsh: 18mg freebase can be sharp. Reduce the wattage, take slower draws or move to a lower strength or a nicotine salt.
• Leaking: overfilled tank, damaged seal or loose assembly. Wipe the device, check each O-ring and seal, do not exceed the fill line and keep the device upright.
• Gurgling or spitting: flooded coil or condensation. Blow gently through the mouthpiece with the fire button off, wipe the drip tray, and let the device rest.
• Dry hits: not enough liquid reaching the cotton. Refill, wait a few minutes, take shorter puffs, and check that the fill port or wicking holes are not blocked.
• Liquid has darkened: gradual darkening is common with age and heat and is not a fault on its own. Only worry if it is accompanied by an off smell or a change in taste you dislike.
• Bottle nozzle blocked or cap stiff: clean the nozzle with warm water, dry it fully and refit the cap. If the cap cracks, replace the bottle or transfer the liquid into a proper empty e-liquid bottle.
• Device will not fire or charge: check the coil connection, clean the contacts with a dry cotton bud and try another cable and charger before assuming the battery is dead.

Some signs mean you should stop using the product altogether. If a battery becomes hot to touch, swells, hisses or smells of chemicals, switch the device off if safe to do so, move it away from anything flammable, and take it to a recycling point once cool. If you feel unwell with symptoms like chest pain, severe dizziness or breathing difficulty, stop vaping and seek medical advice.

For any problem you think is linked to the bottle itself, such as a missing safety seal, a damaged cap or a batch code that does not match, keep the bottle and packaging, take a clear photo and contact the retailer with your order number. That gives them what they need to investigate and, where appropriate, to put things right.

Value for money and how it compares

Judging value on a 10ml e-liquid is easier if you calculate cost per millilitre and cost per day, rather than looking at the bottle price alone. Divide the price on the product page by 10 for the cost per ml, then multiply by your daily use. If you vape 2ml a day, one bottle covers about five days, and the weekly cost is simply the bottle price multiplied by 1.4. Pricing changes, so check the current figure on the product page rather than relying on a number written in a guide.

The 10ml format is more expensive per ml than larger bottles, and there is a reason for that. UK rules cap nicotine e-liquid at 10ml, so a ready-mixed 18mg liquid cannot legally be sold in a bigger bottle. Larger shortfill bottles of 50ml or 100ml contain no nicotine and are meant to be mixed with nicotine shots, which only gets you up to around 3mg to 6mg strength in practice, so they are a different product for a different kind of user. If you need 18mg, a 10ml bottle is the format on offer, and the comparison should be with other 10ml bottles.

Fair comparisons within that group:

• Other 10ml fruit-ice freebase liquids: several UK brands, including Nasty Juice, Elfliq and IVG, sell fruit and ice flavours in 10ml bottles. Prices are usually in a similar band, so flavour preference and strength availability matter more than a few pence per bottle.
• 10ml nicotine salt liquids: brands such as Dinner Lady and Elfliq make nic salt versions at 10mg and 20mg. They are smoother and suit small pod kits, but a 20mg nic salt hits very differently from 18mg freebase, so they are an alternative rather than a like-for-like swap.
• Prefilled pods: convenient and tidy, but typically cost more per ml than a bottle and limit your flavour choice to what the pod maker sells
• Multibuy bundles: buying several 10ml bottles together often lowers the cost per bottle, so check for bundle prices if you plan to stick with one flavour

Where Slush Brew Red Mix earns its place is in the specific mix of strength, bottle size and flavour direction. If you want a cold red-fruit liquid at 18mg for a mouth-to-lung kit and you like the slush style, there is a real match. If you prefer dessert flavours, smoother nic salt hits or sub-ohm clouds, another product will fit better, and it is fair to say so.

To get more from each bottle, use the right coil, prime it properly, avoid overfilling and keep the bottle cool and upright. Most wasted liquid comes from leaks and burnt coils, and a few minutes of care at each refill lowers your cost per day more than shopping around for small price differences.
