Double Brew Nic Salts Apple and Rhubarb 10ml 20mg at a glance

Double Brew Nic Salts Apple and Rhubarb is a 10ml bottle of nicotine salt e-liquid at 20mg/ml, which is the same as 2% nicotine by volume. It comes in the standard 10ml size that UK rules allow for nicotine e-liquid, and 20mg/ml is the highest nicotine strength that can legally be sold in the UK. If you have seen 20mg written as 20mg or 2% on other listings, it is the same thing. The flavour pairs apple with rhubarb, so it sits in the fruit category rather than the dessert, sweets or heavy menthol ranges.

This is a refillable-device product. It is not a disposable and it is not a pod kit. You pour it into a compatible pod system or small tank, and the device does the heating. That distinction matters because a lot of UK shoppers have moved from single-use disposables to refillable setups since single-use vapes were banned from sale on 1 June 2025. A 10ml nic salt bottle is one of the most common ways to keep vaping at a familiar nicotine level while cutting down on waste.

Throughout this guide we are straightforward about what a 10ml 20mg nic salt does well and where it is the wrong choice. Some points depend on the exact formulation printed on the bottle label, such as the VG/PG ratio, so we flag those rather than guess. Always read the label on the bottle you receive, because it is the authoritative source for ingredients, nicotine content and warnings.

Nicotine is addictive. This product is intended for adults who already smoke or vape and want an alternative. If you do not currently use nicotine, you should not start. UK health bodies describe vaping as far less harmful than smoking for adult smokers, but they also stress it is not risk-free.

Flavour profile: how apple and rhubarb work together

Apple and rhubarb is a classic British pairing, most familiar from crumbles and pies, and the idea translates well to e-liquid. Apple provides the sweet, juicy fruit base. Rhubarb brings the sharp, slightly sour, almost green character that stops the whole thing becoming a flat sugary apple. The contrast is the point of the flavour.

What to expect on the inhale is a bright, tart-leaning fruit note. On the exhale, the apple tends to come through more as a rounded sweetness while the rhubarb lingers at the back of the palate as a gentle tang. Because the profile is built on sharpness as well as sweetness, many vapers find it easier to keep vaping through a long day than a dense dessert flavour, which can become cloying.

• Inhale: crisp, tart fruit with a clean edge
• Exhale: softer apple sweetness, rhubarb tang in the finish
• Sweetness level: moderate, not syrupy
• Cooling: not marketed as an ice flavour, so expect little to no menthol chill
• Aftertaste: light, slightly sour, quick to clear

Flavour is subjective, and e-liquid flavour also changes with the device you use. In a low-power pod, the sharper notes are usually more obvious. At higher wattage, fruit liquids tend to taste warmer and sweeter, and the rhubarb can fade. If the first few puffs taste a little muted, give it a few minutes after filling before judging it, because the wick and coil need to saturate fully.

If you like this style, you will probably also enjoy other tart-fruit combinations such as green apple with a sour twist, rhubarb and custard (though that is much sweeter and creamier), or berry and apple blends. If you want straight sweetness with no tang, a candy or tropical flavour would suit you better.

One honest caveat. Descriptions of a flavour are never a substitute for tasting it. Because this comes in a 10ml bottle rather than a large shortfill, the cost of trying it is low, which is one of the sensible reasons to buy 10ml bottles when you are exploring flavours.

Nicotine strength and throat feel at 20mg

At 20mg/ml, this is the top of the UK range. Do not read that as automatically the right choice. Nicotine strength should be matched to how much you smoked or vaped before, and to the device you use. A 20mg nic salt is designed to give a satisfying hit in a low-power device without needing large clouds of vapour, which is why it is popular with people moving away from cigarettes or disposables.

Nicotine salts are formulated with an added acid, typically benzoic acid, which lowers the pH of the liquid. The result is a noticeably smoother throat feel than the same strength in a freebase liquid. At 20mg in freebase form, most people would find the throat hit harsh. In a salt, many find it comfortable, though still firmer than a 10mg or 12mg salt.

• If you smoked a pack a day or roughly 20 cigarettes: 20mg is a reasonable starting point.
• If you smoked 10 or fewer cigarettes a day: consider 10mg or 12mg salts first. Starting at 20mg can feel too strong.
• If you currently use a 20mg disposable: 20mg salt is the most direct match.
• If you are tapering down: buy 20mg now and plan to step down over weeks, once cravings are stable.

Signs that the strength is too high for you include lightheadedness, nausea, a racing pulse, a sore throat that does not clear, and a sense of needing to stop after only a few puffs. If any of these appear, take a break and move to a lower strength. Signs that it is too low are the opposite: you keep vaping more frequently, still crave a cigarette, and feel unsatisfied.

Remember that nicotine absorption depends on puff length and frequency as well as strength. Long, deep pulls from a pod device on a 20mg salt deliver a lot of nicotine quickly. Short, shallow draws deliver far less. If you find 20mg overwhelming, shorter puffs can help while you decide whether to go lower.

For heavy smokers, 20mg salt is often the strength that makes the switch workable. For lighter users, it is more nicotine than they need.

Nic salts versus freebase: what the format changes

Freebase nicotine is the traditional form used in most e-liquids for years. Nicotine salt is nicotine combined with an acid, producing a liquid that absorbs differently. The practical differences are worth knowing before you buy, especially if you are used to freebase liquids or high-powered devices.

• Throat hit: salts are smoother at high strength; freebase at the same strength is harsh.
• Absorption: salts are commonly described as delivering nicotine more quickly, which many ex-smokers find closer to a cigarette.
• Power range: salts are made for low-wattage, higher-resistance devices; freebase is generally used in sub-ohm kit at higher power.
• Vapour production: salts are usually used with smaller clouds because the nicotine level is higher.
• Strength range: salts are normally sold at 10mg to 20mg; freebase for sub-ohm vaping is usually 0mg to 6mg.

Most nic salt liquids are made with a roughly balanced propylene glycol (PG) and vegetable glycerine (VG) mix, commonly around 50/50. That balance carries flavour well and wicks easily in small coils. Higher-VG liquids are thicker and can struggle in small pod coils. We cannot confirm the exact ratio for this specific bottle without the label, so check the printed ingredients if you need to know. Where a ratio is listed on the product page, treat that as the reference.

The consequence of the format is that a nic salt belongs in the right device. If you pour a 20mg salt into a sub-ohm tank running at 60W, you will get a hot, harsh, very strong vape and burn through the bottle quickly. Salt strength in a large sub-ohm setup is both uncomfortable and wasteful. For that kind of kit, a low-nicotine shortfill or freebase is the sensible choice.

On the other hand, if you try to use a 3mg freebase in a low-power pod kit meant for salts, the experience can feel weak and unsatisfying for someone coming from cigarettes. Matching the liquid to the device is simply the most important practical decision.

Devices and battery pairing for a 10ml nic salt bottle

Because Double Brew Nic Salts is an e-liquid, it has no battery of its own. The battery belongs to your device, so the sensible question is which kind of device pairs well with a 20mg 10ml salt. In practice, that means refillable pod systems and small low-power kits.

Most refillable pod kits sold in the UK use a rechargeable lithium battery in the range of roughly 400mAh to 1,000mAh, charged by USB-C. In real use, a 500mAh to 800mAh pod device often lasts a full day for a moderate vaper on a nic salt, and a larger-capacity device can run one to two days. These figures are typical, not guaranteed, because battery life varies with puff frequency, output power and battery age.

• Refillable pod kits: the closest match. Look for a pod that holds around 2ml and a coil rated for salts.
• Pen-style starter kits: small tanks with MTL coils work well and are easy to refill.
• Pod mods with adjustable wattage: useful if you want to fine-tune; keep power low, usually under 15W.
• Closed pod systems: only if the pods are sold as refillable; do not refill a pod that is not designed to be refilled.

Battery and charging practice matters for safety as well as convenience. Charge with the cable supplied, or a reputable USB-C cable, from a standard wall adapter or computer port. Do not leave a device charging unattended overnight, do not charge on soft furnishings, and stop using any device whose battery is swollen, hot to the touch, or damaged. Never carry loose lithium cells in a pocket with keys or coins.

If you are transitioning from a disposable, a pod kit is the natural next step. A disposable commonly contains roughly 2ml of liquid and a fixed battery that is thrown away when empty. A refillable kit lets you reuse the battery for years, and a single 10ml bottle fills a typical 2ml pod about five times, allowing for some priming losses. That is where the environmental and cost advantages come from.

Check that your device supports a salt-friendly resistance and that the pod or tank is in good condition before filling. A worn-out coil will make even a good flavour taste burnt.

Coil and resistance guidance

The coil is where the e-liquid is heated, and for a 20mg nic salt the coil type has a large effect on both flavour and nicotine delivery. As a general principle, nic salts perform best on higher-resistance coils, usually between about 0.8 and 1.4 ohms, which draw less power and produce a tighter, more cigarette-like inhale.

• Regular mesh or ceramic MTL coils (about 0.8 to 1.2 ohm): a good fit for 20mg salts. They deliver the flavour cleanly at low power.
• Standard cotton coils (about 1.0 to 1.6 ohm): also suitable and widely available, though they can degrade faster with sweet or fruit liquids.
• Sub-ohm coils (below 0.5 ohm): not recommended for a 20mg salt. They push too much vapour and too much nicotine per puff.

Fruit liquids, including apple and rhubarb, usually contain sweeteners and flavour compounds that can darken a coil over time. This is called coil gunk, and it is a normal consequence of vaping sweet flavours rather than a fault in the liquid. You can often tell the coil is ageing when flavours turn muted, toasted or faintly bitter. Replace the coil or pod when that happens rather than trying to push through, because a tired coil spoils the flavour and increases the chance of dry hits.

Priming is the most important step with any new coil. Fill the pod or tank, then leave it for at least five to ten minutes before the first puff, so the cotton or mesh is fully soaked. Skipping this step is the single biggest cause of a burnt first impression. Some people also add a couple of drops directly onto the coil inlet, which helps.

For adjustable-wattage devices, start at the lower end of the coil's recommended range and move up only if the vapour feels cold or thin. Fruit flavours generally taste best at moderate warmth. Pushing power high will rarely improve the taste and will shorten coil life, drain the battery faster and make the 20mg feel stronger than intended.

If you are unsure what your device needs, check the manufacturer's manual. Most pod kits specify the recommended liquid type, so look for guidance mentioning nic salts or 10mg to 20mg strengths.

Who Double Brew Apple and Rhubarb 20mg is for

This product suits a fairly specific group of adult nicotine users. Being honest about that group saves you money and disappointment.

• Smokers moving to vaping: a 20mg salt is a common starting point for someone who has been smoking regularly and wants enough nicotine to avoid going back.
• Disposable users switching to refillables: if you were using 20mg single-use vapes, this is the straightforward replacement, and you can use it in a reusable pod kit.
• People who like tart fruit rather than candy or dessert: the rhubarb tang is the distinguishing feature.
• Vapers who prefer a tight, low-power inhale: nic salts in small devices suit mouth-to-lung style.
• Budget-minded vapers: a bottle used in a refillable device is typically cheaper per millilitre than a disposable.

Equally, there are people who should look elsewhere.

• Anyone who has never used nicotine: do not start vaping, and certainly not at the maximum strength.
• Under 18s: it is illegal to sell nicotine products to anyone under 18 in the UK, and illegal for adults to buy them on their behalf.
• Light or social smokers: 20mg is probably too strong. Look at 10mg or 12mg salts, or even lower freebase.
• Sub-ohm and cloud-chasing fans: this strength in that kind of device is wasteful and harsh.
• Anyone who is pregnant, has a heart condition or other relevant medical concern: speak to a doctor or pharmacist first. Stop-smoking services in the UK can offer free support and licensed products.

It is also worth being realistic about expectations. A bottle of e-liquid will not make quitting nicotine easy by itself. Many people find that gradually lowering strength over weeks, with support from a local stop-smoking service, works better than going straight from 20mg to nothing.

For households, always store nicotine liquid securely away from children and pets, in the original bottle with the child-resistant cap fitted. Accidental swallowing or skin contact with e-liquid is a genuine risk, particularly at 20mg.

How to use Double Brew Nic Salts correctly

Using a bottled e-liquid is easy once you have done it a couple of times, but the first attempt trips up many new users. Follow these steps for a clean, leak-free fill.

• Check compatibility: confirm your device is designed for refillable use with nic salts.
• Switch the device off or remove the pod: prevents accidental firing during filling.
• Wash and dry your hands: keeps nicotine off your skin and dirt out of the pod.
• Open the pod's fill port: most have a silicone plug that lifts or pulls out.
• Shake the bottle gently, then fill slowly: aim the nozzle at the side wall of the pod, not directly into the central airflow tube.
• Stop below the maximum fill line: leave a small air gap. Overfilling is a top cause of leaks and flooded coils.
• Close the plug and wipe off any spillage: use a tissue, as nicotine on the skin is absorbed.
• Let it prime for 5 to 10 minutes: upright, resting on the base.

When you start vaping, take gentle, steady draws of two to three seconds. A nic salt at 20mg does not need long pulls. Pause between puffs so the coil can re-wet and so you can judge how the nicotine feels. Many beginners take too many long puffs in the first few minutes and feel ill, which is a nicotine overdose reaction, not a sign of a faulty product.

Do not mix this liquid with other brands or strengths inside the same pod unless you are sure of the combined nicotine level, because the result can end up above the legal cap or simply too strong for you. If you want to change flavour, rinse the pod with warm water, dry it fully and refill. Some people keep one pod per flavour to avoid ghosting, where the previous flavour lingers on the coil and cotton.

Store the bottle upright with the cap on tight, in a cool, dark place away from heat and direct sunlight. Sunlight and warmth degrade both flavour and nicotine over time. Once opened, a nicotine e-liquid is best used within a few months for the best taste, and the bottle will carry a best-before date as a guide.

Troubleshooting common problems

Most problems with a refillable setup are small and fixable. Here are the issues we hear about most often and the usual cause for each.

• Burnt or dry taste: usually a poorly primed or worn-out coil, or the liquid level is too low. Refill, prime for ten minutes, and replace the coil if the problem persists.
• Gurgling or spitting: too much condensation or liquid in the airflow path. Blow gently through the mouthpiece to clear it and wipe it dry.
• Leaking from the pod or bottom of the device: typically overfilling, a loose plug, or a cracked pod. Clean, refill to a lower level and check the seals.
• Flavour seems weak: could be vaper's tongue, where repeated exposure to one flavour dulls your sense of it. Try a different flavour for a day or two, or simply drink water and give it a break. Cold liquid also tastes flatter, so keep it at room temperature.
• Throat is too harsh: the strength may be too high for you, or the wattage is too high for the liquid. Lower power, shorten the puffs, or step down to a 10mg or 12mg salt.
• Not enough nicotine hit: you may be on a coil that is too low-resistance, or you are puffing too lightly. Check the coil's rating and try slightly longer puffs.
• Device does not fire: check battery level, connection of the pod, and whether the device has an auto-draw sensor blocked by condensation.
• Lightheaded, nauseous, or headache: stop immediately. This suggests too much nicotine. Rest, drink water, and consider a lower strength.

If a device battery becomes extremely hot, smells strange, swells or smokes, stop using it, move it away from flammable material if you can do so safely, and do not charge it again. For anything involving a damaged lithium battery, contact the manufacturer or your local waste facility on how to dispose of it safely.

If you suspect the e-liquid itself is faulty, for example it smells wrong, has separated, or looks cloudy and unusual, stop using it, keep the bottle and packaging, and contact customer service with your order number and a photo. We would rather replace a bottle than have you vape something that seems off.

Value for money and how long a 10ml bottle lasts

Value in vaping is about cost per day, not just the price on the shelf. A 10ml bottle looks like a small amount, but it goes further than most people assume, particularly with nic salts, where each puff delivers a lot of nicotine and consumption tends to be lower than with low-strength freebase.

Consumption varies a great deal between people. Light users who vape a few times a day may take a week or more to finish 10ml. Moderate to heavy ex-smokers on a pod kit often use somewhere in the range of 1.5ml to 3ml a day, which puts a 10ml bottle at roughly three to seven days. Treat those as rough guides, not promises. Your own puff frequency and the device you use will move the number.

• Light use (1ml a day or less): a bottle can last more than a week.
• Moderate use (about 2ml a day): around five days.
• Heavy use (3ml or more a day): three days or fewer.

To compare cost fairly, divide the bottle price by 10 to get a price per millilitre, then compare that with a disposable at its price divided by the roughly 2ml it holds. Refillable setups usually win clearly once you account for the fact that the battery and pod are reused. You do pay upfront for a device, plus occasional replacement pods or coils, so the saving shows up over weeks rather than on day one.

The sensible way to buy is to pick up a couple of bottles when you find a flavour that works, rather than a single bottle at a time, because you avoid running out mid-week and can often save on delivery by combining items. Buying in bulk beyond a few bottles is only worthwhile once you are sure of the flavour, since taste preferences can shift after a few weeks of the same liquid.

One more point on value. Cheaper is not automatically better. A very cheap liquid from an unknown source may have inconsistent nicotine content or poorer quality control. Buying from a UK retailer selling registered products, with clear labelling, is part of what you pay for.

How it compares with alternatives

No single product is right for everyone, so here is a fair comparison with the main alternatives a shopper is likely to be weighing.

Versus other 10ml nic salt ranges. The UK market has many 10ml nic salt lines from well-known brands, including established names such as Nasty Salt, IVG Salts, Elfliq and Hayati, plus many smaller labels. They all cover the broad flavour territories of fruit, ice, candy and dessert. The honest comparison is mostly about flavour accuracy and personal taste, because strength and bottle size are essentially standardised. A tart apple and rhubarb combination is a narrower offering than the common blue raspberry or mango ice options, which is a point in its favour if you want something less obvious, and a point against it if you want the widest choice of familiar flavours.

Versus disposable vapes. Single-use disposables were banned from sale in Great Britain on 1 June 2025. That means a refillable setup with a bottled liquid is the realistic way to get the same convenience and nicotine level. Disposables were simpler, with no filling, but a bottle in a reusable kit is cheaper per millilitre and generates far less electronic and plastic waste. The trade-off is the small amount of effort in filling and maintaining the device.

Versus freebase liquids and shortfills. Freebase and shortfills are the better choice for sub-ohm devices and lower nicotine strengths, where you want large vapour and a gentler hit. They are less suited to people coming off cigarettes who need a firmer nicotine delivery. Shortfills also require you to add nicotine shots if you want any nicotine, which is more complicated than a ready-to-use 10ml salt.

Versus nicotine replacement products. Patches, gum, lozenges and inhalators are licensed medicines and have strong evidence behind them for quitting. They are worth considering, especially alongside behavioural support. A vape offers the hand-to-mouth habit and flavour that some people value, but it is a consumer product, not a licensed treatment.

In short, Double Brew Apple and Rhubarb is a competent choice if you want a tart fruit 20mg salt for a pod kit. It is not the right answer if your device is high-powered, your preferred strength is low, or you want an ice-heavy flavour.

Storage, safety, UK rules and recycling

Handling nicotine e-liquid responsibly protects you, your household and the environment. These are the points that matter most for UK buyers.

UK rules in plain terms. Nicotine e-liquid in the UK is limited to a maximum of 20mg/ml and a maximum bottle size of 10ml for refill liquids. Bottles must carry health warnings, an ingredient list, and be child-resistant and tamper-evident. Sellers must verify that the buyer is 18 or over. These rules are in place to reduce risk, and a 10ml 20mg bottle sits right at the permitted limits.

Safe storage.

• Keep bottles out of reach and sight of children and pets.
• Store upright, capped, away from heat, radiators and direct sunlight.
• Do not decant into unlabelled containers, drink bottles or food containers.
• If liquid gets on your skin, wash with soap and water straight away. If it is swallowed or gets in the eyes, seek urgent medical help and have the bottle with you.

Recycling and disposal. Empty plastic bottles can often go in household plastic recycling once fully empty, though the dropper nozzle and cap may need to be removed and your council may have its own guidance, so check locally. Do not pour leftover liquid down the drain. Instead, let a small amount dry out on kitchen paper in a safe place or take surplus liquid to your household waste recycling centre.

Batteries and electronic devices are different. Vape devices, pods with electronics, and any lithium batteries should never go in household bins or standard recycling. They can start fires in collection trucks and recycling plants. Take them to a dedicated drop-off point, such as a household waste recycling centre or a retailer offering vape and battery take-back. In the UK, shops that sell vapes are expected to take back used vape products, so you can usually return them in store.

Reducing waste. The simplest steps are to choose a refillable device, replace only the coil or pod rather than the whole kit, and recycle packaging where you can. These small habits make a real difference over a year of vaping compared with a stream of single-use products.

Always check the printed label on your bottle, as it overrides any general information given here.
