Double Brew J.Fruit Nic Salt 10ml 20mg at a Glance

Double Brew Nic Salts J.Fruit is a 10ml bottle of nicotine salt e-liquid at 20mg/ml, made for refillable pod kits and other low-power mouth-to-lung devices. It belongs to the fruit side of the Double Brew line, a wide catalogue that also runs through dessert, ice, soda and cream blends. The bottle label gives this flavour only as J.Fruit, so this page describes it by style, as a sweet and rounded fruit blend, rather than pretending to quote a recipe sheet we do not have.

The aim of this guide is to answer the questions a UK buyer usually has before ordering. What does 20mg/ml feel like on the inhale? Which devices suit it, and which do not? How many puffs and how many days should a bottle last? What goes wrong when people use it badly, and how does it stack up against other 10ml salts? You will also find the situations where this is the wrong purchase, because an honest 'not for you' saves everyone a returned parcel.

The essentials before the detail:

  • Format: one 10ml bottle of nic salt e-liquid, the largest bottle size UK rules permit for nicotine-containing liquid.
  • Strength: 20mg/ml (2% nicotine), which is the maximum strength that can legally be sold in the UK.
  • Flavour: J.Fruit, a sweet, fruit-forward profile with no cooling descriptor in the name.
  • Best used in: refillable pod systems and fixed low-wattage MTL kits, roughly 8W to 18W.
  • Not for: sub-ohm tanks, high-wattage mods, or anyone who has never used nicotine.
  • Age restriction: 18+ only, with age checks on UK orders.

Context matters here. Since 1 June 2025, single-use disposable vapes can no longer be sold in the UK, which pushed most nicotine users towards refillable pod kits and bottled liquids like this one. A bottled salt costs less per puff than the disposables it replaced and creates far less waste, provided the hardware and the empties are recycled properly, which we cover further down.

Specifications and What They Mean in Practice

A specification list is only useful if you know how to read it, so here is the data for this bottle, followed by what each line means in daily use.

  • Product: Double Brew Nic Salts, J.Fruit flavour.
  • Bottle size: 10ml, in a squeezable plastic bottle with a narrow dropper tip and a child-resistant, tamper-evident cap.
  • Nicotine type and strength: nicotine salt, 20mg/ml (2%).
  • Total nicotine in the bottle: 200mg (10ml multiplied by 20mg/ml).
  • Typical base ratio: salts in this style are usually balanced or PG-leaning, commonly around 50VG/50PG. Read the exact ratio on the label you receive, because batches and suppliers can differ.
  • Intended hardware: refillable pod kits and MTL devices running about 8W to 18W, with coil resistance in the region of 0.8 to 1.4 ohm.
  • Fill capacity: enough to fill a standard 2ml pod roughly four to five times, allowing for priming and a little left in the bottle.
  • Estimated puff yield: about 200 to 300 puffs per millilitre in a typical pod kit, so around 2,000 to 3,000 puffs per bottle. This is an estimate, not a laboratory figure.
  • Shelf life: printed on the bottle as a best-before date, normally a year or more from manufacture if stored properly.
  • Age restriction: 18+.

The 200mg total nicotine figure is worth a moment. It is the reason UK rules require a child-resistant cap, and it is why the bottle should live out of sight and reach of children and pets. It also helps you plan your intake: if a bottle lasts you a week, you are taking in roughly 28mg of nicotine from it per day on average, only part of which is absorbed.

The base ratio decides how the liquid behaves in a small coil. A balanced or PG-leaning mix thins out enough to wick quickly through the cotton in a pod coil, carries flavour clearly and gives a firmer throat sensation. A very high VG mix would be thicker, prone to starving a small coil, and softer on the throat. If your bottle states a very different ratio from the one above, believe the label, and match your device to it.

On the puff estimate: 200 to 300 puffs per millilitre assumes two-second draws on a low-power device. Long, slow, deep draws or higher wattage use more liquid per puff, so a bottle will empty sooner. Short sips on a modest setting stretch it. The figure is useful for budgeting, not for guarantees.

Flavour Profile: Reading the J.Fruit Name

The bottle gives only the name J.Fruit. In vape labelling, short names like this are usually house shorthand for a sweet fruit blend, and different people read the J as juicy, jelly or even jackfruit. Rather than guess at a recipe, we describe what a sweet mixed-fruit nic salt in this style typically does, and we suggest treating your first bottle as the test of whether it suits your palate. If the label or the supplier's information on your batch says something more specific, trust that over our general description.

Sweet fruit salts tend to move through three stages on each puff:

  • Opening: a bright, sugary fruit note arrives first, usually the most recognisable part of the flavour. This is the stage that fades fastest as you vape through a pod, so it is the part you notice most on the first fill of a fresh coil.
  • Body: a rounder, juicier middle where several fruit notes blend rather than stand apart. In multi-fruit liquids this is where the mixture earns its keep, and where lower-quality blends tend to taste like generic sweet syrup.
  • Finish: a lingering sweetness on the tongue and a mild peppery warmth at the back of the throat. That warmth comes from the nicotine salt, not the flavouring, and it is stronger at 20mg/ml than at 10mg/ml.

Sweetness level. Expect this to sit at the sweeter end of the range. Nothing in the name suggests a menthol or cooling additive, so you should not expect the icy edge found in the Double Brew lines labelled Ice, such as Cherry Ice, Banana Ice or Blue Slush Ice. If you like a cool exhale, pick one of those; if you prefer a warm, plain fruit flavour, this is the more natural fit.

How nicotine salt changes taste. Salt nicotine is gentler than freebase at equal strength, yet at 20mg/ml you still taste a faint pepper note under the fruit. Some people like it because it adds backbone to a sweet liquid; others find it cuts through the delicate top notes. If the pepper dominates, the fix is usually a lower strength or smaller puffs, not a different flavour.

Flavour fatigue. Very sweet fruit liquids can become tiring after a few days of exclusive use. Vapers often report that the taste seems to fade, which is mostly the palate adapting. Keeping a second flavour on hand, a tobacco or a mint for example, and swapping every day or two keeps the fruit tasting fresh when you return to it.

Coil effects. Sugar-heavy liquids build residue on coils faster than plain or tobacco flavours. If J.Fruit starts tasting dull, flat or faintly scorched after a week or so, the liquid has probably not gone off; the coil has. A fresh pod usually restores the flavour completely.

Performance and Puff Delivery

With any e-liquid, performance is a joint effort between the liquid and the device. The liquid determines the nicotine delivery, the throat sensation and the vapour character. The device determines how much of that is produced per puff. At 20mg/ml in a salt formulation, J.Fruit is built for compact hardware and short, gentle draws.

Throat hit. Nic salts feel smoother than freebase at the same strength, but 20mg/ml is still a clear, firm sensation, noticeably stronger than the 10mg/ml tier. Daily smokers often describe it as the closest match to a cigarette. If you are used to 3mg or 6mg freebase in a large tank, the first few puffs of 20mg salt will feel sharp, so take slower draws for the first day while your throat adjusts.

Vapour production. Because this is an MTL liquid, expect modest clouds. A pod kit at 10W to 15W produces a thin, dense vapour that disperses quickly. That is by design: the point is nicotine satisfaction and flavour, not volume. Anyone chasing big clouds wants a different product category, and 20mg/ml salt should never go into a sub-ohm setup.

Nicotine delivery. Salts reach the bloodstream faster than freebase at equivalent strength, which is one reason they work as a cigarette replacement. Many users find that a handful of puffs settles the urge, so they vape less often than they did on lower strengths. That is helpful, but it also means it is easy to overdo nicotine without noticing, especially with a sweet flavour that goes down easily.

Real-world puff counts depend on how you vape. As a rough guide for a 2ml pod:

  • Light use (5 to 10 minutes of puffing across the day): a pod can last two to three days.
  • Moderate use (replacing around 10 cigarettes): expect about a pod a day, so a 10ml bottle lasts a week to ten days.
  • Heavy use (replacing a pack a day): up to two or more pods a day, which brings a bottle down to three to five days.

Draw style. MTL devices want a slow, tight draw, like sipping through a narrow straw. Dragging hard on a pod kit pulls more liquid than the coil can vaporise, producing weak flavour, a hot taste and, over time, a coil that fails early. A gentle, steady two to three seconds suits both the liquid and the hardware.

Consistency across the pod. A well-primed fresh coil gives steady flavour for most of a pod. In the last quarter of the tank, flavour can taste thinner as the wick has less liquid to pull. Refill before the pod is completely empty, rather than running it dry, to protect the coil and avoid dry hits.

Bottle Design, Packaging and Build Quality

An e-liquid has no screen, no battery and no buttons, so build quality comes down to the bottle, the cap and the label. Those details matter more than they sound, because a leaking bottle or a cap that is difficult to seal is the most common practical complaint with 10ml liquids.

Bottle. The 10ml bottle is soft, squeezable plastic with a thin dropper tip, built to line up with the fill port of a pod. The tip is narrow enough for most refillable pods, but it is worth checking your own device: a few kits use a very small port that needs a slow, patient squeeze rather than a quick one. Squeezing slowly also reduces the glug of air that sends liquid splashing onto the pod.

Cap. Nicotine liquids sold in the UK must carry a child-resistant, tamper-evident closure. In practice that means a cap that needs a firm press and twist, with a ring that breaks on first opening. It can feel stiff the first time. Once open, make sure you refit it fully every time, because a cap sitting loosely is how bottles end up leaking in a bag or pocket.

Label. The label should show the product name, nicotine strength, volume, ingredients, a health warning, batch information and a best-before date. If any of those are missing or illegible on the bottle you receive, tell us. The label is also where you confirm the actual VG/PG ratio, which the product page cannot always state for every batch.

Packaging. Bottles are normally shipped in a protective bag or box inside our outer packaging. The risk to a 10ml bottle in transit is pressure on the squeezable body, so we recommend opening the parcel soon after it arrives and checking the bottle for seepage around the cap, before you store it.

Handling and storage.

  • Store upright, in a cool, dry, dark place. Heat and sunlight degrade nicotine and flavour, and darken the liquid.
  • Keep the bottle away from children and pets at all times. Nicotine is toxic if swallowed or absorbed through the skin in quantity.
  • Wipe the tip after filling so residue does not collect around the neck.
  • If you spill liquid on your skin, wash it off with soap and water.

Recycling. Empty bottles are small plastic items. Check whether your local council accepts them in kerbside plastic recycling; many do once the bottle is empty and the cap is on. If yours does not, a household waste recycling centre will take them. Do not pour leftover liquid down a drain.

Battery and Charging: Matching the Right Device to This Liquid

The bottle itself has no battery, but the device you pair it with decides how well it works, and battery behaviour is the second most common source of questions after flavour. J.Fruit at 20mg/ml is designed for compact pod kits, so here is how their power systems tend to work.

Typical battery size. Refillable pod kits generally carry internal batteries somewhere between about 400mAh and 1,000mAh. A smaller battery, such as 400 to 600mAh, suits light and moderate users who can top up during the day. A battery in the 800 to 1,000mAh bracket suits heavier use and may last a full day for someone replacing around ten cigarettes.

Charging. Most current pod kits charge over USB-C. A full charge usually takes somewhere between 30 and 90 minutes, depending on the battery size and the charger. Use a quality charger or a standard USB port rather than an unknown cheap adapter, and avoid fast chargers rated far above what the kit was designed for. Do not leave a device charging unattended overnight, and stop using any device that gets hot to the touch, swells or smells unusual.

Output and liquid. Many pod kits deliver a fixed output, often around 10W to 14W, which matches nic salts well. Variable-wattage kits give you more control. As a starting point for a 20mg salt:

  • Begin at the low end of the device's range, around 8W to 10W for a 1.0 ohm coil.
  • Raise the power in small steps if flavour feels muted, stopping as soon as the vapour feels warm or harsh.
  • Keep the setting within the coil's printed wattage range, which is stamped on the coil or listed in the manual.

Battery drain and the liquid. A battery that runs flat quickly is normally a sign of heavy use or an ageing cell, not of the liquid. However, a coil that is gunked up with sweet residue can draw more current to produce a puff, so if battery life drops sharply and the flavour is dull, change the coil first.

Safe disposal and recycling. Vapes and pod kits contain lithium batteries and should never go in household bins or general recycling. Under UK waste electrical rules, retailers that sell vapes must offer take-back, and household waste recycling centres run drop-off points for electrical items. Many supermarkets and high-street shops also have small-electricals bins. Pods and coils are best treated the same way if they contain metal parts, and bottles can usually go in plastic recycling once empty.

Coil and Mesh Technology: What Suits 20mg Salts

The coil is where the liquid becomes vapour, and a mismatch between coil and liquid is behind most disappointing experiences. Nic salts at 20mg/ml need a coil that heats gently and wicks reliably, which points to specific designs.

Resistance. Pod-style MTL coils typically sit between 0.8 and 1.4 ohm. Higher resistance (1.2 to 1.4 ohm) draws less power and gives a tighter, warmer vapour with a firm throat hit, which suits a strong salt. Lower resistance (0.6 to 0.8 ohm) heats faster and gives denser vapour and fuller flavour but uses more liquid and more battery. For J.Fruit, a coil around 0.8 to 1.2 ohm is the practical sweet spot.

Coil construction. The common designs you will meet are:

  • Round-wire cotton coils: the traditional approach. Simple, cheap and tolerant of a range of liquids, though flavour can be slightly less even than mesh.
  • Mesh coils: a flat sheet of mesh gives a larger heating surface, faster ramp-up and more even flavour. They tend to produce fuller vapour per puff and work well with fruit flavours, although they use a little more battery.
  • Ceramic coils: a porous ceramic wick in place of cotton. They resist burning and give a clean, consistent taste, but the structure can be slower to absorb thicker liquids, so priming matters.

Priming. Every new coil needs a short wait after the first fill. Leave it for five to ten minutes so the wick saturates fully, then take two or three gentle draws without firing the device to pull liquid through. Skipping this step is the single biggest cause of dry hits and burnt coils, and a burnt coil permanently tastes unpleasant.

Coil life with sweet liquids. Fruit salts generally shorten coil life compared with tobacco or menthol. As a rule of thumb, expect a coil or pod to last roughly one to two weeks of normal use. Signs that it is ready to change include:

  • Flavour that is flat or faintly burnt even at a fresh fill.
  • Gurgling or spitting that did not occur before.
  • Vapour that looks thinner than usual.
  • A sweet, sticky residue visible around the coil or pod base.

What not to do. Do not put a 20mg salt in a sub-ohm tank with a coil below 0.5 ohm. Those coils are designed for much higher power and far more liquid, and using a high-strength salt in them delivers a harsh, excessive nicotine dose. For that style of vaping the correct liquid is a low-strength freebase shortfill, not this bottle.

Nicotine Strength Guidance: Is 20mg/ml Right for You?

The strength printed on a bottle is the most important choice you make. This listing is the 20mg/ml version, which equals 2% nicotine and is the highest strength allowed in UK retail. Whether it is right depends on your smoking history, your device and how you intend to vape.

What 20mg/ml means in practice. Salt nicotine is absorbed more quickly and feels smoother than freebase, so 20mg/ml salt hits harder than the same number of milligrams of freebase would suggest, although it is not simply the same as a cigarette. Most people who smoke around 10 or more cigarettes a day find 20mg/ml salt the strength that actually keeps cravings away.

As a loose guide, not medical advice:

  • Smoking 15 or more cigarettes a day: 20mg/ml is the usual starting point.
  • Smoking 10 to 15 a day: 20mg/ml may be right, but try 10mg/ml if it feels too strong after a few days.
  • Smoking fewer than 10 a day or social smoking: 10mg/ml is normally the better choice, and sometimes lower.
  • Never smoked or vaped: do not start with nicotine at all.

Signs 20mg/ml is too strong. A harsh, scratchy throat hit even on gentle puffs, lightheadedness, nausea, a racing pulse, headaches or feeling jittery after vaping all suggest you are taking more nicotine than you need. Put the device down, drink water, and move to a lower strength or take fewer puffs.

Signs it is too weak. If you keep reaching for the device every few minutes without relief, or you drift back to cigarettes, the strength may be too low, or the device may be too small to deliver enough. Moving up a strength or using a more capable pod kit is a reasonable response.

Salt versus freebase. Salts are built for low-power devices, where freebase at the same strength would be unpleasantly harsh. Freebase suits larger tanks and higher wattage. Do not mix them up: using freebase in a tiny pod works poorly, and using a 20mg salt in a high-power device overdoses the user.

Stepping down. Many vapers start at 20mg/ml and reduce to 10mg/ml after a few weeks as their craving settles, and some go lower still. There is no deadline, and the sensible approach is to go down only when you are comfortable. If you want help quitting entirely, the NHS Stop Smoking service in your area can offer free support alongside vaping.

Vaping is not risk-free and nicotine is addictive, but for adult smokers who switch completely it carries far lower risk than continuing to smoke. If you do not smoke, you do not need this product.

Who J.Fruit Is For, and Who Should Skip It

No flavour or strength suits everyone, so here is a plain view of who gets the most from this bottle and who would be better off looking elsewhere.

J.Fruit 20mg is a good fit if you:

  • Are an adult smoker moving to vaping and want a strength that matches a regular smoking habit.
  • Already use a refillable pod kit or MTL device and need a fruit flavour in a standard 10ml bottle.
  • Prefer sweet, rounded fruit flavours over tobacco, menthol or dessert profiles.
  • Want a cost-effective way to refill a pod instead of buying throwaway devices, which can no longer be sold in the UK anyway.
  • Like to keep a rotation of flavours and are happy to buy several 10ml bottles at once.

You should look elsewhere if you:

  • Are under 18. Sales of nicotine vapes to under-18s are illegal in the UK and we will not supply them.
  • Have never smoked or used nicotine. Vaping is not risk-free and nicotine is addictive.
  • Are pregnant or breastfeeding, or have a heart condition, and have not first spoken to a GP or pharmacist.
  • Use a sub-ohm tank or high-wattage mod. A 20mg salt is far too strong for those devices.
  • Dislike sweet flavours. The profile is unlikely to win you round.
  • Want a cooling, menthol-forward vape. Look for an Ice variant instead.
  • Need a lower nicotine strength. This listing is 20mg/ml only, so choose a 10mg/ml or lower product from the range or from another brand.

Beginners. If you are brand new to vaping as a smoker, 20mg/ml is normal at the start, but do not go straight to a high-power device. A simple pod kit and gentle puffs are a better introduction than a feature-packed mod. Give it a week before deciding whether the strength and the flavour suit you.

Experienced vapers. If you already run salts in a pod, J.Fruit will not need explaining; the question is simply whether a sweet fruit blend belongs in your rotation. Because it carries no menthol, it makes a useful contrast to ice flavours in a two-bottle setup.

How to Fill, Use and Store Double Brew J.Fruit

Using a 10ml bottle is simple, but small mistakes cause most of the problems people report. Follow these steps for a clean fill and a coil that lasts.

Filling a pod.

  • Switch the device off and, if it has one, remove the pod. Work over a tissue or sink.
  • Open the fill port. Most pods use a silicone bung or a sliding cover.
  • Remove the bottle cap by pressing down and twisting. Place the tip into the fill port at a slight angle so air can escape as the liquid goes in.
  • Squeeze gently and fill to just below the maximum line. Never fill past the marked limit or into the central air tube.
  • Close the port firmly and wipe any spilled liquid from the pod and bottle neck.
  • Refit the bottle cap completely, then wait five to ten minutes before the first puff so the wick can saturate.

First puffs. Take two or three gentle draws without pressing the button or firing the device to pull liquid into the wick, then vape normally. Short, steady puffs of two to three seconds are enough. Do not chain vape, since it overheats the coil and delivers more nicotine than you intend.

While using it.

  • Refill before the pod is empty. Running it dry gives dry hits and shortens coil life.
  • Keep the device upright when not in use so liquid does not pool in the airflow channels.
  • Do not mix different flavours in the same pod without rinsing; the taste turns muddy, and the coil will keep traces of the last flavour.
  • Let the device rest between sessions rather than vaping continuously.

Switching flavour. When moving from J.Fruit to another bottle, either fit a new pod or run the old one empty and rinse the reservoir with warm water, then dry it fully before refilling. Residual sweetness is the usual culprit when a new flavour tastes strangely muddled.

Storing the bottle. After filling, refit the cap and store the bottle upright in a cool, dark place, away from radiators, cars and windowsills. Keep it out of the reach of children and pets. A bottle stored properly keeps its flavour for months; one left in a hot car can turn dark and taste harsh within days.

Travelling. A sealed bottle can travel in a bag, but pressure changes in a plane cabin can push liquid out of a pod. Empty your pod before flying, carry the bottle in a sealed plastic bag, and check the airline's rules on e-liquid quantities and carry-on limits.

Troubleshooting: Common Problems and How to Fix Them

Most issues with a nic salt are fixable in a minute or two once you know the cause. These are the ones we hear about most often.

Burnt or dry taste. Almost always a coil problem. Causes are a pod that was not primed, a pod run too low on liquid, a coil worn out by sugary residue, or chain vaping that dried the wick. Fix: refill, wait ten minutes, take a few gentle draws without firing, and replace the coil if the taste persists.

Weak or flat flavour. If the flavour seems faint, check that the pod is properly filled and the coil is not clogged. Sweet liquids gum coils sooner than other flavours, so a flat taste after a week is usually the coil rather than the liquid. A fresh pod typically fixes it. Also consider flavour fatigue; swapping to another flavour for a day or two resets your palate.

Gurgling or spitting. This means too much liquid reaching the coil or condensation in the airway. Causes include overfilling, a draw that is too strong, or a cracked pod. Fix: wipe the mouthpiece and airflow, empty out any excess, and draw more gently.

Leaking from the pod or device. Check that the pod is seated firmly, the fill port is closed fully and the pod is not overfilled. Pressure changes and heat make leaks worse. If the pod itself is cracked, it needs replacing.

Leaking bottle. If liquid seeps around the cap, wipe the neck, refit the cap fully, and store the bottle upright. If a new bottle arrives leaking or damaged, contact us with your order number and a photo.

Harsh throat hit or coughing. At 20mg/ml this can happen to people moving from lower strengths. Take shorter and slower puffs, lower the device power, or step down to a 10mg/ml product. A hot, harsh hit with a burnt taste points to a coil problem instead.

Dizziness, nausea or headache. These are signs of too much nicotine. Stop vaping, get some fresh air, drink water, and move to a lower strength next time. If symptoms are severe or persist, seek medical advice.

No vapour or the device will not fire. Check the battery charge, pod seating and the airflow opening. If the device flashes a warning, consult its manual. A completely dead pod may have a failed coil. Replace it before assuming the device is faulty.

Sticky residue or darkened liquid. A bottle that has darkened can simply have aged or been exposed to heat or light. Small colour changes are common in nic salts and not necessarily harmful, but if the smell or taste is off, do not use it.

Value for Money and How It Compares With Other 10ml Nic Salts

A 10ml salt looks cheap on the shelf, so it helps to work out what you actually pay per day. Using an illustrative figure for a bottle of around £3.99, and assuming 2,000 to 3,000 puffs per bottle, the cost works out at roughly 13p to 20p per hundred puffs. For a moderate user going through a bottle in a week, that is under 60p a day in liquid, plus the cost of pods or coils. Check the current page price, and any multibuy offers, for your own calculation.

That compares well with the disposable vapes that used to dominate the market and can no longer be sold in the UK. A refillable pod kit plus bottled salts costs more up front but much less over weeks of use, and the waste is limited to small bottles and occasional pods.

Running costs to include:

  • The liquid itself: about one 10ml bottle every week to ten days for moderate use.
  • Replacement pods or coils: usually every one to two weeks, and sooner with sweet flavours.
  • Charging electricity: a negligible amount.
  • The device: a one-off cost that should last many months with care.

How the range compares. The 10ml 20mg salt category is crowded, and several well-known ranges sit alongside Double Brew. We compare by type of product, not by quality claims, because batches and tastes vary.

  • Elfliq and similar disposable-brand salts: built on a familiar fruit-and-ice formula, they suit people who want that style specifically. Double Brew offers a wider spread of dessert and cream flavours alongside its fruit and ice options.
  • IVG Salt and Hayati nic salts: broad flavour libraries with strong ice and sweet-fruit selections. They overlap heavily with Double Brew, so the choice usually comes down to which specific flavour appeals to you and which is cheaper that week.
  • Bar Juice 5000 and Nasty-style salts: often priced in the same band and aimed at similar users. Differences are mostly flavour recipe and sweetness level.

Where Double Brew fits. It is a mainstream, mid-priced option with plenty of choice across fruit, ice and dessert lines, which makes it easy to build a multi-bottle rotation. Its weakness, if you want one, is that flavour names can be less descriptive than some rivals, as J.Fruit shows. If you prefer a clearly described recipe, you may be happier with a brand that publishes full tasting notes.

Is it worth buying? If you already know you like sweet fruit salts at 20mg/ml and have a suitable pod kit, it is a reasonable, fairly priced option. If you are unsure of the flavour, buy a single bottle first rather than a multipack, and decide after a week.

Pros & cons

Pros

  • Best value per ml in the category
  • Choose your own device and coil
  • Available in a wide strength ladder

Cons

  • Refilling can leak if you overfill
  • Coil priming has a small learning curve
  • You handle the bottle — less discreet than pods

Customer Buying Tips

  • Match the strength to how much you smoked: 20+/day → 10-20 mg nic salt; 10/day → 10 mg; under 5/day → 3-6 mg freebase.
  • Match the ratio to your device: pod kits take 50/50, sub-ohm tanks take 70/30 shortfill.
  • Don't overfill: leaving the airhole clear prevents gurgling and leaking.
  • Shake before use so the nicotine and flavour integrate evenly.

Frequently asked questions

Is 20mg/ml the right strength for me?

20mg/ml (2%) is the usual starting point for adults who smoke around 10 or more cigarettes a day, and it is the maximum strength allowed in UK retail. If you smoke less, or find the throat hit harsh, a 10mg/ml salt is often a better fit. If you have never smoked or used nicotine, you should not start.

How do I charge the device I use this liquid in?

The bottle has no battery, but most refillable pod kits charge by USB-C, and a full charge normally takes about 30 to 90 minutes. Use a quality charger, avoid leaving the device charging unattended overnight, and stop using any kit that gets very hot or swells. Never put a vape in household bins; use an electrical recycling drop-off point.

Does J.Fruit come in other flavours, and can I swap between them?

Yes. The Double Brew line includes many other flavours, such as Cherry Ice, Banana Ice, Blue Slush Ice, Apple Muffin and Caramel Frappe, all in 10ml bottles. You can swap flavours freely, but fit a fresh pod or rinse and dry the reservoir first, because leftover liquid makes the new flavour taste muddy.

How long will a 10ml bottle last?

Plan on roughly 2,000 to 3,000 puffs per bottle in a typical pod kit. For a moderate user that means about a week to ten days, while light users can stretch it to two weeks or more and heavy users may finish it in three to five days. Longer draws and higher power use liquid faster.

Is it good value compared with disposables?

Generally yes. Single-use disposables can no longer be sold in the UK, and a refillable pod kit with bottled salts costs far less per puff once you have the device. With a bottle at around £4 you are looking at well under £1 a day of liquid for moderate use, plus the occasional replacement pod.

Who should not buy this liquid?

Anyone under 18, anyone who has never smoked or used nicotine, and people who are pregnant, breastfeeding or have a heart condition without medical advice. It is also the wrong product for sub-ohm tanks and high-wattage mods, and for anyone who wants a cooling menthol flavour or a lower nicotine strength.

Can I use it in any vape device?

No. It is made for refillable pod kits and low-power mouth-to-lung devices, roughly 8W to 18W with coil resistance around 0.8 to 1.4 ohm. Do not use 20mg salt in a sub-ohm tank or a high-power mod, because the nicotine delivery will be far too strong.

Do you deliver across the UK and check age?

Yes, we deliver across the UK, and nicotine orders are restricted to customers aged 18 or over, so age verification applies. Delivery options, timings and charges are shown at checkout, and the delivery page has the current details.

What if my bottle arrives leaking, damaged or wrong?

Contact us with your order number and a photo of the problem and we will put it right. Opened e-liquid generally cannot be returned for hygiene and safety reasons, but faulty, damaged or incorrect items are covered, and our returns page sets out the exact terms.

How should I recycle the bottle and my old devices?

Empty 10ml bottles can usually go in household plastic recycling, or to a household waste recycling centre if your council does not accept them. Pod kits, batteries and other devices must go to an electrical recycling drop-off point, such as a council centre or a retailer take-back scheme, never into general waste.
