Double Brew Nic Salts Blue Razz Lemonade 10ml 20mg at a glance

Double Brew Nic Salts Blue Razz Lemonade is a 10ml bottle of nicotine salt e-liquid at 20mg/ml, which is the same as 2% nicotine by volume. Both the 10ml bottle size and the 20mg/ml strength are the upper limits UK rules allow for refillable nicotine e-liquid, so this is the highest-strength, largest-size bottle a UK retailer can legally supply. The flavour pairs blue raspberry, the sweet, tangy, slightly candy-like taste familiar from slush drinks and ice pops, with a tart lemonade note that adds a citrus edge to the finish.

This is a refillable-device product. It is not a disposable and it is not a pre-filled pod kit. You pour it into a compatible pod system or small tank, and the device does the heating. That distinction matters because single-use vapes were banned from sale in the UK on 1 June 2025, and many people who used to buy 600-puff disposables now buy a bottle and a rechargeable kit instead. One 10ml bottle holds roughly five times the liquid of a typical 2ml disposable, and the cost per millilitre is usually far lower.

The 20mg/ml ceiling is the same one that applies to every nicotine vaping product sold in the UK, which is why you will see 20mg on pods, bottles and the old disposables alike. If you were used to a 20mg disposable, this bottle gives you the same nicotine strength in a format you can refill and reuse.

Flavour profile: how blue razz and lemonade work together

Blue razz is not a real fruit. It is a confectionery flavour that grew out of blue raspberry sweets and drinks, and it tastes like a bright, sweet raspberry with a faint sour edge. In e-liquid it is one of the most recognisable candy-fruit profiles, and it tends to be sweet first and fruity second. On its own it can feel a little flat and sugary after a few hours of vaping, which is exactly the problem the lemonade half of this blend is meant to solve.

The lemonade note brings a sweet-sharp citrus character, closer to a cloudy lemon drink than to a fresh lemon squeezed into water. E-liquid cannot carry carbonation, so expect a still lemonade rather than a fizzy one. What the lemon does is cut across the sweetness and add a clean, slightly tart finish, so each puff ends on citrus instead of lingering as syrup.

Because the flavour is a blend, what you notice depends on how you vape.

• On the inhale: the blue raspberry sweetness usually leads, with a rounded fruity body.
• On the exhale: the lemon tends to come forward and the finish feels brighter and slightly sour.
• At lower power: the sweet raspberry side is more prominent and the vapour is cooler and smoother.
• At slightly higher power: the citrus sharpens, the vapour warms, and the sweetness reads as more caramelised and less crisp.

The name does not mention ice, menthol or cooling, so treat this as a non-menthol flavour. Some vapers find that sweet fruit liquids feel slightly cool on the throat anyway, but there is no reason to expect the icy blast you would get from a blue razz ice variant. If cooling matters to you, look at an ice version of a similar flavour instead.

This is a sweet, juice-style flavour, not a dessert or a tobacco profile. If you like fruit sweets, sherbet, slush drinks or lemon sherbet, it sits in your territory. If you prefer dry, savoury or menthol-heavy flavours, it probably will not. Sweet liquids can also cause flavour fatigue, sometimes called vaper's tongue, where a flavour you enjoyed last week suddenly tastes muted. Switching to a different flavour for a day or two usually resets it.

Performance and puff delivery

A bottle of e-liquid has no puff count printed on it the way a disposable does, so the honest answer is that performance depends on the device you put it in. What we can do is give realistic ranges. In a typical low-power mouth-to-lung pod kit, one millilitre of nic salt liquid gives roughly 150 to 250 puffs, depending on how long and how often you draw. On that basis a 10ml bottle works out at around 1,500 to 2,500 puffs. Treat those as estimates rather than guarantees, because long draws, higher wattage and a worn coil all use liquid faster.

For comparison, a single-use disposable of the old 600-puff kind held about 2ml of liquid. A 10ml bottle is therefore around five disposables worth of liquid, and it holds about 200mg of nicotine in total against around 40mg in a 2ml disposable at the same strength.

Here is what to expect from the vapour itself.

• Vapour volume: modest. Nic salt liquid is meant for low-power devices, so you get a compact, flavourful puff rather than a large cloud.
• Throat hit: smooth for the strength. Nic salts are formulated to feel gentler than a freebase liquid at the same milligram level.
• Nicotine delivery: quick and steady. Salt nicotine is absorbed efficiently, so many people feel satisfied after a handful of puffs.
• Flavour consistency: strong when the coil is fresh, drifting slowly downward as the coil ages.

The first few puffs after a refill can taste slightly weaker while the new liquid soaks into the coil. Wait a few minutes after filling, then take a couple of short, gentle draws to prime the coil before you vape normally. That small habit avoids most early complaints about thin flavour or a dry hit.

Because nic salts deliver nicotine efficiently, you will usually vape less often than you would on a low-strength freebase liquid. That is a feature rather than a flaw, but it also means you should resist the urge to chain-vape. If you find yourself taking dozens of puffs in a row, the strength is probably too high for you.

Nicotine strength at 20mg and how nic salts differ from freebase

20mg/ml is the highest nicotine strength that can legally be sold in the UK. It is designed for people who smoked heavily, roughly a pack a day or more, or who are used to 20mg disposables. The numbers are not a measure of harshness on their own: the same 20mg/ml feels very different depending on whether the nicotine is in freebase form or salt form.

Freebase nicotine is the traditional form used in most older e-liquids. At higher strengths it is harsh on the throat, which is why freebase liquids are usually sold at 3mg to 6mg for sub-ohm devices. Nicotine salts add a mild acid, usually benzoic acid, which lowers the pH of the liquid. That makes the same amount of nicotine much smoother to inhale, and it is what allows a 20mg liquid to be vaped comfortably in a small pod kit. Salt nicotine is also taken up faster by the body, so the satisfying hit arrives sooner.

A rough guide to choosing a strength looks like this.

• 20mg: suitable for heavy smokers switching fully, or for people stepping down from 20mg disposables.
• 10mg to 12mg: suitable for people who smoked around 10 to 15 cigarettes a day, or who find 20mg too strong.
• 5mg to 6mg: suitable for light smokers or for people reducing their intake gradually.

This bottle is the 20mg option, so it is aimed at the first group. Signs that 20mg is too strong for you include dizziness, nausea, a racing heart, a headache after vaping or a persistent harsh feel in the throat. If any of these happen, stop and consider a lower strength. Signs that it is too weak include cravings returning within an hour or constantly reaching for the device.

If you are trying to stop smoking, the NHS says that vaping is far less harmful than smoking but is not risk-free, and that it is not recommended for people who do not already smoke. Local stop smoking services can combine vaping with behavioural support, and speaking to a pharmacist or GP is sensible if you have a heart condition, are pregnant or take regular medication. Nicotine is addictive, and nobody who does not already use nicotine should start.

Bottle design, packaging, storage and recycling

A 10ml e-liquid bottle is a simple object, but the design details affect how easy it is to fill a device without waste. Bottles in this size are typically soft plastic with a narrow dropper nozzle, which lets you squeeze liquid precisely into a small pod fill port. A tip that fits the port is useful, because pod fill holes can be as small as a few millimetres wide. If your device has an unusually narrow port, a spare blunt-tip needle bottle is a cheap fix.

UK rules shape the packaging. Nicotine e-liquid has to be sold in child-resistant, tamper-evident bottles, carry health warnings and an ingredient list, and be notified to the regulator before sale. The 10ml cap on bottle size is also part of those rules. Check that the seal is intact when your order arrives. If the tamper-evident ring is broken or the cap is loose, contact customer service rather than using it.

Storing the bottle.

• Keep it upright, capped and out of direct sunlight and heat, because warmth and light degrade flavour over time.
• Store it away from children and pets, ideally in a cupboard or drawer that closes.
• Do not decant liquid into unlabelled containers, drinks bottles or food containers.
• Wipe the nozzle and threads after filling so residue does not pool under the cap.

Stored sensibly, sealed nic salt liquid generally keeps its quality for many months. If the colour has darkened or the smell has changed noticeably, the flavour has probably aged and you may prefer to replace it.

Recycling and disposal. Empty plastic bottles can often go in household plastic recycling once they are fully empty, though the nozzle and cap may need separating and your council may have its own guidance, so check locally. Do not pour leftover liquid down the sink. Batteries and electronic devices need separate handling. Vape kits, rechargeable batteries and any pod with electronics should never go in household bins or kerbside recycling, because lithium cells can start fires in collection vehicles. Take them to a household waste recycling centre drop-off point or to a retailer that offers vape take-back. In the UK, shops that sell vapes are expected to take back used vape products, so returning old kit in store is usually possible.

Devices, battery and charging

Nic salt liquids work best in devices that were designed for them. That means refillable pod kits and compact mouth-to-lung tanks, which use modest power, restrict the airflow and produce a small, dense puff. In practice the device you pair with this bottle will usually have a battery of roughly 400mAh to 1,000mAh, a refillable pod or cartridge of 2ml, and a USB-C charging port. The 2ml pod size is a legal limit in the UK for refillable tanks, and it is also why a 10ml bottle gives you around five fills.

Battery capacity affects how often you recharge. As a rough guide, a 500mAh battery in a low-power pod kit lasts a moderate vaper most of a day, and a 1,000mAh battery often lasts a day or two. Heavy use, higher wattage, cold weather and an ageing battery all shorten that. Because nic salts are used at low wattage, you usually get better battery life than you would from a high-power tank.

Charging safely is simple if you follow a few habits.

• Use the cable that came with the device, or a reputable USB-C cable, and a standard phone-style charger or computer port.
• Avoid cheap unbranded chargers, which can deliver unstable power.
• Do not charge unattended for long periods, and do not leave a device charging overnight on a bed or sofa.
• Charging a typical pod kit takes about 30 to 90 minutes. Unplug it once the indicator shows full.
• Do not carry a device loose in a pocket with keys or coins, as short circuits can damage the battery.
• Stop using a device that gets hot, swells, hisses or smells of burning, and recycle it properly.

It is better to match this bottle with a device that can deliver nicotine at a steady, gentle pace than to use it in anything with variable high power. Many pod kits have a draw-activated firing system with no buttons, which suits nic salts well because you simply inhale. Adjustable-wattage mods can work too, as long as you keep the output low and pair them with a coil of a suitable resistance. If you do not own a device yet, a basic refillable pod kit is the usual starting point, and the liquid itself has no battery or charging requirement of its own.

Coil and mesh technology: matching resistance to a 20mg salt

The coil is the part that heats the liquid, and it has more influence on flavour than most people expect. For a 20mg nic salt like this one, the target is a higher-resistance coil in a low-power device. Resistance is measured in ohms, and for nic salts the usual range is about 0.8 to 1.4 ohm, run at roughly 10 to 25 watts depending on the device. Lower-resistance sub-ohm coils pull far more power, produce a lot more vapour and will make a 20mg salt taste harsh while burning through the bottle.

Two coil designs are common in refillable pods.

• Round wire coils: a wire wrapped around a cotton wick. Simple and widely available, they heat up reliably but can create hot spots that mute subtle flavours over time.
• Mesh coils: a flat or curved sheet of metal mesh pressed against the wick. The larger surface area heats the liquid more evenly and quickly, which tends to give steadier flavour and slightly better vapour production at low power.

A mesh coil is especially helpful with candy-fruit and citrus flavours, because an even heating profile helps keep the sweetness and the tartness distinct instead of blending into a single sugary note. Most modern refillable pods use a mesh coil in this range, though wire coils are still common in budget kits.

Sweet liquids can leave residue on the coil, since sugars and sweeteners caramelise when heated. You may notice a darker coil after a week or two, and a muted or slightly burnt taste means the coil is near the end of its life. A typical pod coil lasts around one to two weeks of regular use, or roughly one to two 10ml bottles, but that varies with wattage, puffing style and how sweet the liquid is.

To get the most from each coil, prime it properly when new, avoid chain vaping, keep the wattage low and change it as soon as the flavour fades. Do not try to clean and reuse a coil that tastes burnt, because the damage is permanent. If you are unsure which coil fits your device, check the manual or the model name printed on the pod, since coils are not interchangeable between brands.

Who Double Brew Blue Razz Lemonade 20mg is for

This bottle is aimed at a fairly specific group of adults. The strongest fit is a current or former smoker who needs a strong nicotine hit and prefers a sweet, fruity taste to tobacco or menthol. If you smoked around a pack a day and want a 20mg liquid that is gentle enough to vape all day in a small device, it is the right strength.

It also suits several other situations.

• Former disposable users: if you used to buy 20mg disposables in sweet fruit flavours, a refillable kit and a 10ml bottle replicate that experience at a lower cost per millilitre and with far less waste.
• Vapers who want a candy-and-citrus flavour: blue razz is a staple flavour, and the lemon makes it less cloying than a straight blue raspberry.
• People who already own a low-power pod kit: this is a straightforward refill rather than a new system to learn.
• Anyone who wants a refillable alternative to the disposables ban: a bottle and a pod kit are a legal, widely sold route.

It is not a good choice for everyone. Think carefully before buying if any of the following applies.

• You do not smoke or vape already. 20mg is a high dose for a new user and nicotine is addictive. This product is for adults who already use nicotine.
• You are under 18. It is illegal to sell nicotine vaping products to under-18s and proxy purchasing is also an offence.
• You smoked only a few cigarettes a day. A 10mg or 12mg strength is usually more suitable.
• You are pregnant, or you have a heart or other medical condition. Speak to a doctor or pharmacist before using any nicotine product.
• You want large clouds. This bottle is formulated for low-power devices and will not perform well in sub-ohm kits.
• You prefer menthol or tobacco flavours. This is a sweet fruit liquid and will not satisfy that taste.

If you are not sure whether this is right for you, a stop smoking adviser, pharmacist or GP can talk through nicotine strength and device choice without judgement.

How to fill and use it correctly

Filling a pod is quick once you have done it a couple of times, and doing it carefully prevents most leaks and bad-tasting coils. The steps below apply to nearly all refillable pod kits, but your own manual takes priority if it differs.

• Step 1, prepare: make sure the device is switched off or unplugged, and wash and dry your hands. Remove the pod from the battery section.
• Step 2, open the fill port: most pods have a rubber bung or a sliding cover. Pull or slide it open so you can see the fill hole.
• Step 3, fill: tilt the pod and squeeze the bottle gently so liquid runs down the inside wall. Fill to just below the maximum line. Do not fill to the brim, and take care not to cover the central airflow tube.
• Step 4, close up: push the bung fully in or close the cover until it is seated. Wipe any liquid from the outside of the pod.
• Step 5, wait: leave the pod upright for five to ten minutes with the device off, so the cotton can absorb the liquid. This is the most skipped step and the most important for avoiding dry hits.
• Step 6, prime and vape: reconnect the pod and take two or three short, gentle draws without firing at full strength, then vape normally.

Some people like to start the first few draws slowly and keep each puff to around two to four seconds. Mouth-to-lung means drawing the vapour into your mouth first, pausing, then inhaling. That is how nic salts are designed to be used, and it is also the most economical way to vape them. Avoid deep lung inhales at 20mg, which can feel intense and are unnecessary with salt nicotine.

Between fills, keep the airflow slots clear of lint and liquid, and top the pod up before it is completely empty. Running a pod dry is the quickest way to burn a coil. When you swap to a different flavour, empty and rinse the pod with warm water, dry it fully and then refill, otherwise the two flavours will mix. Keep the device upright when stored, as this reduces leaking, and check that the pod is seated firmly before every session.

Troubleshooting common problems

Most problems with refillable setups come down to a handful of causes. Here is a practical checklist.

• Burnt or acrid taste: the coil is worn, or it is running dry. Replace the coil and refill before the pod gets low. Avoid chain vaping, which does not give the wick time to resoak. Never keep using a burnt coil.
• Weak or muted flavour: this is often vaper's tongue or a tired coil. Switch flavours for a day, drink some water and try a new coil if the problem persists. Sweet liquids tend to build up residue faster, so expect to replace coils a little more often.
• Dry hit on the first puffs: you did not wait long enough after filling. Leave the pod upright for ten minutes and prime with gentle draws.
• Leaking from the pod or device: the pod is overfilled, the bung is not seated, or the pod has a cracked seam. Wipe the device, fill to a lower level and replace the pod if the crack is visible. Pressure changes during flights can also cause leaks, so travel with a fully empty pod where possible.
• Gurgling noise: excess liquid pooling around the coil. Blow gently back through the mouthpiece to clear it, and wipe away any pooled liquid.
• Throat feels too harsh: try a lower wattage, a longer pause between puffs, or a lower nicotine strength. If a mild burning feeling continues, 20mg may simply be too strong for you.
• Device will not fire or flashes: check the battery level, the connection between pod and battery, and whether the pod is correctly seated. Clean the contacts with a dry cotton bud. If it flashes repeatedly after charging, it may need replacing.
• Battery drains quickly: an old battery, cold weather or a high-power setting could be the cause. Reduce the wattage and charge properly.

Persistent headaches, nausea, a racing heart or chest tightness after vaping mean you should stop and seek advice. If a device overheats, swells or smells of burning, stop using it immediately, move it away from flammable materials, and dispose of it through the proper recycling route. If a problem looks like a defect rather than a usage issue, contact customer service with your order number and a photo.

Value for money and how long a 10ml bottle lasts

Value with e-liquid comes down to cost per millilitre and how many millilitres you use. A 10ml bottle at 20mg contains about 200mg of nicotine, and a typical pod kit uses it far more slowly than you might think. How long it lasts depends on how heavily you vape, which is why we give ranges rather than a single promise.

• Light use: a handful of short sessions through the day. A bottle can last one to two weeks.
• Moderate use: regular vaping across the day, as a former pack-a-day smoker often does once settled. Expect roughly five to ten days.
• Heavy use: frequent long draws or chain vaping. A bottle may disappear in three to four days, though that is also a sign that the strength may be lower than you need.

To judge value properly, compare the price per millilitre. A 10ml bottle at a few pounds works out at a small fraction of what you pay per millilitre for a 2ml disposable. As an illustration only, if a 2ml disposable cost around £6, that is £3 per millilitre, while a 10ml bottle costing £4 works out at 40p per millilitre. Check the live price on this page to run your own calculation, because shop prices change.

There are other costs to include, and a fair comparison counts them.

• The device: a basic refillable pod kit is a one-off purchase, and it can last many months.
• Coils or pods: replacement pods or coils are the main running cost, and for a moderate vaper they come to around one coil every week or two.
• Charging: the electricity cost is negligible.

Even with those included, the total cost of vaping refillable is usually lower than a disposable habit after the first few weeks. The saving is greatest if you vape every day, and smaller if you vape only now and then. There is also a practical value in the environmental side: you recycle one kit and a few bottles, instead of throwing away a battery each time.

One more point on value is that you pay for 20mg whether you need it or not. If you find you vape this liquid very frequently but still feel jittery, a lower strength may give you a better experience for the same money.

How it compares with the alternatives

It helps to see where a 10ml nic salt bottle sits against the other ways to buy nicotine vapour in the UK. Here is a fair comparison, including the places where this product is a weaker choice.

Versus disposables. Disposables were convenient: no filling, no coils, nothing to learn. Single-use models are now banned from sale in the UK, and where rechargeable pre-filled alternatives exist they still cost more per millilitre than a bottle. The trade-off with a bottle is that you need a device, a bit of setup and some maintenance. If you value zero fuss above all, pre-filled pod systems are simpler. If you value running cost and reduced waste, the bottle wins.

Versus pre-filled pods. Closed pods are neat and leak less, but you are locked into one brand's flavours and pay a premium. A bottle gives you flavour choice and a lower price per millilitre, in exchange for filling the pod yourself.

Versus other 10ml nic salt ranges. There are many 10ml nic salt brands in the UK, most in similar strengths and flavours. Blue raspberry, lemonade and other candy-fruit blends are common across the market. The difference between brands comes down to how well the sweetness is balanced and how consistent the flavour is, which is subjective. If you already have a favourite brand, it is reasonable to compare this one against it in the same device before committing to a stock-up.

Versus shortfills and freebase. Shortfill bottles come in larger sizes (typically 50ml or 100ml) with no nicotine, to which you add a separate nicotine shot. They are designed for sub-ohm devices and work out cheaper per millilitre, but they produce large clouds and are not suited to low-power pod kits. If you use a pod kit, a nic salt is the right format. If you use a sub-ohm tank, this bottle is not.

Versus other strengths and flavours. Lower strengths such as 10mg suit lighter smokers, and ice or menthol variants of blue raspberry suit people who want a cooler hit. This bottle is a sweet, non-menthol 20mg, and a neighbouring product may suit you better if you want something different.

The honest summary is that this bottle is a sensible choice for adults who already need 20mg, own or plan to buy a low-power refillable kit, and like sweet fruit with a citrus lift. It is less suitable if you want convenience without effort, big clouds, a cooling effect or a lower dose.
