Double Brew Nic Salts Lemon and Lime 10ml 20mg at a glance

Double Brew Nic Salts 10ml 20mg Lemon and Lime is a bottle of nicotine salt e-liquid, listed at £1.10 for 10ml with a nicotine strength of 20mg/ml, which is the same as 2% by volume. Both figures sit at the ceiling that UK rules allow for refillable nicotine e-liquid: 10ml is the largest bottle a retailer can supply, and 20mg/ml is the strongest permitted. The flavour is a straightforward citrus pairing of lemon and lime, sold under the Double brand.

It is worth being clear about what this product is, because search results for vaping mix several categories together. This is not a disposable vape, not a pre-filled pod and not a device. It is the liquid you pour into a refillable pod kit or small tank, and the device you already own does the heating. Single-use disposable vapes were banned from sale across Great Britain from 1 June 2025, and many adults who used to buy 600-puff disposables now buy a bottle like this one together with a rechargeable pod kit. At £1.10 a bottle the liquid is a very small part of the running cost. The real outlay is the one-off purchase of a device.

Here is the quick reference.

• Product type: nicotine salt e-liquid, not a device
• Bottle size: 10ml
• Nicotine strength: 20mg/ml (2%), the only strength listed for this flavour
• Flavour: lemon and lime
• Price: £1.10 per bottle, which works out at about 11p per millilitre
• Suits: refillable mouth-to-lung pod kits and low-power starter devices
• Does not suit: high-power sub-ohm tanks, non-smokers and anyone under 18

The exact PG/VG ratio and the batch details are printed on the bottle label. We would rather point you to the printed figures than quote a ratio from memory, so check the label when it arrives if the ratio matters for your device. Everything else on this page is written to help you decide whether a citrus nic salt at the top legal strength fits the way you vape, and how to get the most flavour and value out of it if it does.

This product is for adults only. You must be 18 or over to buy it, and it is intended for adults who already smoke or vape nicotine. If you do not use nicotine today, this is not the product to start with.

Flavour profile: lemon first, lime behind it

Lemon and lime is one of the simplest flavour pairings in e-liquid, and also one of the easiest to get wrong, because citrus can drift toward either cleaning-product sharpness or sugary squash. The idea behind this bottle is a balanced middle: a bright lemon note on the inhale, with lime arriving a beat later and carrying through the exhale. Taste is personal, so treat the notes below as a guide to what the flavour is aiming for rather than a guarantee of how every palate will read it.

On the inhale, expect a clean, tart citrus hit that sits at the front of the mouth. Lemon tends to read as the sweeter and rounder of the two citrus fruits, closer to lemonade or lemon sherbet than to a squeezed wedge. Lime follows with a greener, slightly more bitter edge, the kind of note you get from lime zest or lime cordial, and it gives the flavour some length so it does not vanish the moment you finish the puff.

On the exhale, the sweetness settles and the lime character takes over. Most citrus e-liquids lean on a small amount of sweetener to keep the acidity comfortable, and you can expect that here. It should taste like a soft-drink style citrus rather than a dessert. There is no cream, no bakery note and no menthol cooling listed in the name, so if you want a cold, icy finish you would look at a different flavour in the range.

• Inhale: bright, tart lemon with a light sweetness
• Mid-puff: lime peel and a faint green bitterness that keeps the flavour from tasting flat
• Exhale: softer citrus sweetness with a short, clean finish
• Overall character: refreshing and drink-like, not heavy or sticky

Citrus flavours have a reputation for being the easiest to tire of in a single sitting, and for being the ones where your tongue stops registering the taste after a long session. That is normal sensory fatigue rather than a fault with the liquid. If lemon and lime seems to fade after an hour of steady vaping, take a break, drink some water and try again, and the flavour usually comes back. It also helps to let a freshly filled pod rest before the first puff, which is covered in the how-to-use section below.

Because nic salts are usually vaped at low power, the flavour is delivered warm rather than hot. That suits citrus well, since high temperatures can push lemon and lime toward a harsh, peppery note. Low wattage keeps the profile smooth and lets the lime show up properly.

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 offer is a realistic range. 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 figures as estimates rather than guarantees, because long draws, higher wattage and an ageing coil all use liquid faster.

For context, a single-use disposable of the old 600-puff kind held about 2ml of liquid. A 10ml bottle therefore holds the equivalent of around five of those, and at 20mg/ml it contains about 200mg of nicotine in total against roughly 40mg in a 2ml disposable at the same strength. That is a useful reminder that a full bottle is a considerable amount of nicotine, and it must be stored with the same care you would give any nicotine product.

Here is what to expect from the vapour itself.

• Vapour volume: modest. Nic salt liquids are made for low-power devices and produce a tighter, smaller cloud than the high-VG liquids used in sub-ohm tanks.
• Throat hit: noticeable but smooth. Salts at 20mg/ml feel gentler on the throat than a freebase liquid at the same strength, although the citrus acidity adds a little bite.
• Nicotine delivery: quick. Nicotine salts are absorbed faster than freebase nicotine, which is why many people find a few puffs enough to feel satisfied.
• Flavour intensity: clear at low wattage, with the lemon note more obvious early in the puff and lime later.

The draw style matters more than anything else. Mouth-to-lung means you pull vapour into your mouth first, pause for a second or two, then inhale. That is the same motion as drawing on a cigarette and it is what pod kits are designed around. If you try to lung-inhale directly on a 20mg salt, you will probably cough and take in more nicotine than you intended.

Consistency across the bottle is generally good with salts, since the lower power means less thermal stress on the liquid. You should find the first fill and the last fill taste much the same, provided you store the bottle properly and keep your coil in good condition. If the last few millilitres taste different, the cause is almost always the coil rather than the liquid.

Bottle design and build quality

The packaging is the only physical product in this listing, so it is fair to judge it. The liquid comes in a 10ml plastic bottle with a narrow nozzle, which is the standard format for nicotine e-liquid in the UK. The slim tip is designed to fit into the fill ports of most refillable pod kits, so you can fill a pod without a funnel and with less mess than a wide-necked bottle would give you.

UK rules require nicotine e-liquid to be sold with a child-resistant closure and tamper-evident packaging, and you should see both. The cap is pushed down and turned to open, and a break-away ring around the neck shows whether the bottle has been opened before. If that ring is already broken when your order arrives, do not use the liquid and contact us straight away.

The bottle label carries the legally required information. Expect to find:

• the product name, flavour and nicotine strength in mg/ml
• the ingredient list and a nicotine addiction health warning
• a batch number and a best-before date
• the manufacturer or supplier details and the volume

The plastic is soft enough to squeeze gently, which gives you control over the flow, but it should not be squeezed hard. Squeezing a nic salt bottle with force pushes out a burst of liquid that can flood a pod, and a flooded pod is the most common cause of leaking and gurgling. Hold the bottle upright, rest the nozzle against the fill port and squeeze slowly.

Good build quality at this price point means a few simple things: a cap that threads on cleanly and seals, a nozzle that does not drip between fills, and a label that does not smudge when handled. It is worth wiping the nozzle with a tissue after each fill, because a little residue on the tip can stick to your fingers and create a mess in a bag or pocket.

Light and heat degrade e-liquid over time, so the bottle is best kept in the box or in a drawer. A semi-opaque bottle gives some protection from light, but it is not a substitute for sensible storage. Keep it upright, keep the cap fully closed, and keep it out of reach of children and pets. More on that in the safety section below.

Battery and charging: what your device needs

This is an e-liquid, so there is no battery in the bottle and nothing to charge. The battery that matters is the one in your pod kit or starter device. Because a lot of buyers pair a bottle like this one with a new device, here is what is worth knowing so that your hardware does the liquid justice. We are describing the category in general terms, and your device manual is always the authority on your specific model.

Refillable pod kits that suit nic salts typically carry batteries in the range of roughly 400mAh to 1,000mAh. A smaller battery is perfectly adequate for light to moderate use, since salts are vaped at low power. A larger battery means less frequent charging and is helpful if you vape steadily throughout the day.

• Charging port: most current pod kits charge over USB-C. Use the cable supplied with the device and a standard phone charger or a computer USB port.
• Charge time: small pod batteries commonly take somewhere between 30 minutes and 90 minutes to charge fully. Check the manual for your device rather than assuming.
• Overnight charging: avoid leaving a device charging unattended for long periods. Unplug it once it is full, and never charge it under a pillow or on a soft surface.
• Cables and adapters: use a reputable charger. Cheap unbranded adapters are a common cause of battery problems.

Battery level also affects flavour. A device running low on charge can deliver weaker or inconsistent heat, and a lemon and lime liquid can taste thin and slightly metallic as a result. If the flavour seems to fall away toward the end of the day, charge the device before you decide the liquid has gone off.

Do not use a high-powered box mod with this e-liquid. A 20mg nic salt is formulated for low wattage, usually somewhere around 8W to 15W in a pod system. Pushing a salt through a powerful device will burn the liquid, produce a harsh throat hit and deliver far more nicotine per puff than the formulation is designed for.

When a battery finally reaches the end of its life, do not put the device in your household bin. Lithium batteries are a fire risk in bin lorries and recycling plants. Vapes and their batteries are electrical waste, and you can hand them in at household waste recycling centres or at retailers that offer a take-back service. Look for a drop-off point near you through your local council.

Coil and mesh choices for a 20mg nic salt

The coil is the part of your device that turns liquid into vapour, and the match between coil and liquid decides how this lemon and lime tastes. Nic salts are made for low-power, higher-resistance coils, and that is the guidance to follow here. We cannot know which device you own, so these are category-level pointers rather than a claim about any particular kit.

• Resistance: coils in the roughly 0.8 ohm to 1.2 ohm range are the usual match for 20mg nic salts. They run at modest wattage, they sip liquid slowly and they give the tight mouth-to-lung draw that suits the strength.
• Mesh coils: a mesh coil spreads heat over a wider area, which tends to give a more even flavour and smoother vapour. Mesh coils around 0.6 ohm to 0.8 ohm appear in some pod kits and work well with salts as long as you keep the power low.
• Ceramic and cotton coils: both are common. Cotton-wicked coils are generally strong on flavour from the first puff, while ceramic coils are valued for consistency and longer life.

Citrus e-liquids are generally kind to coils, but no flavour is free of build-up. Any sweetened liquid leaves a thin film on the wick over time, and when that film darkens and gets crusted you start to taste a flat, slightly burnt note. For a typical user, a coil or pod will last somewhere between one and two weeks, and a bottle of this liquid will normally outlast at least one coil change. Replace the coil when the flavour dulls, rather than waiting for it to fail completely.

Priming matters more than most people realise. A new coil is dry, and if you fire it before the wick has soaked up liquid, you scorch the cotton and ruin the coil within a few puffs. After inserting a fresh coil, drip a few drops directly onto the wick if your device allows, fill the pod, and wait five to ten minutes before vaping.

One more caution. Do not put a nic salt into a sub-ohm tank designed for high-VG liquids and high wattage. The coils in those tanks, usually below 0.5 ohm, are made to burn through a lot of liquid at 40W or more. At 20mg/ml that would deliver a very large amount of nicotine with every puff, and the liquid would be wasted. If you want to vape in a sub-ohm style, you need a low-strength shortfill, not a 20mg salt.

Finally, check that the nozzle fits your fill port. Most 10ml bottles fit most pods, but a few devices use a very small hole. If the tip is too wide, use a small blunt-tipped refill needle or squeeze gently so that the liquid goes in without overflowing.

Choosing your nicotine strength: is 20mg right for you?

This listing is for 20mg/ml only, so the practical question is whether that is the right level for you. It is the top of the legal range, which makes it a strong product, and it is worth thinking about before you buy rather than after.

Nicotine salt liquids are different from traditional freebase liquids. Salts use a form of nicotine that is smoother on the throat, which is why they can be sold and vaped at higher strengths without feeling harsh. The trade-off is that nicotine reaches the bloodstream faster. A 20mg salt therefore feels both smoother and stronger than the number alone suggests.

As a general guide, based on how nicotine strengths are commonly used in the UK market:

• 20mg/ml (2%): usually chosen by adults who currently smoke around ten or more cigarettes a day, or who find lower strengths leave them reaching for a cigarette.
• 10mg to 12mg/ml: a more common choice for people who smoke fewer cigarettes, or who vape a lot through the day and want a gentler hit per puff.
• Below 10mg/ml: more usual with larger devices and lower-nicotine shortfill liquids.

If you are unsure, a lower strength is the more cautious starting point, and lower strengths are common across the category. Check that your preferred flavour is available at the strength you want before you order, because the lemon and lime listing here is the 20mg bottle.

Signs that a strength is too high include dizziness, nausea, a racing heartbeat, headaches, sweating or a feeling of being lightheaded. If you notice any of these, stop vaping, drink some water and rest. Do not continue until you feel normal, and if you are worried about your symptoms, speak to a pharmacist or your GP. Nicotine is addictive, and a strength that is too high for your tolerance can make an unpleasant experience out of something that is meant to be routine.

You can also moderate your intake by taking shorter, less frequent puffs, by lowering the wattage on adjustable devices, or by using a pod with a tighter airflow. These all reduce how much nicotine you take per puff without changing the liquid.

Nicotine is not suitable for everyone. If you are pregnant, breastfeeding, have a heart condition or take regular medication, talk to a healthcare professional before using any nicotine product. We do not make medical claims about this product, and nothing on this page is medical advice.

Who this e-liquid is for, and who should skip it

A product is only good value if it matches the person buying it. Here is an honest picture of who benefits from Double Brew Nic Salts Lemon and Lime, and who would be better served elsewhere.

This is likely a good fit if you:

• are an adult who currently smokes or uses nicotine and wants a refillable alternative to a disposable
• own a pod kit or low-power starter device that is designed for nic salts
• prefer fruit and citrus flavours over tobacco, dessert or menthol profiles
• want a low-cost bottle to try before committing to a larger order
• like a light, drink-style flavour that is not heavy or sticky

You should look elsewhere if you:

• are under 18, which means you cannot legally buy or use this product
• do not currently use nicotine. A 20mg salt is a strong product for someone with no tolerance, and there is no reason to start
• own a high-power sub-ohm tank or box mod, where a shortfill is the correct type of liquid
• want a cooling or ice finish, because this flavour is not listed with menthol
• find sharp or sour tastes unpleasant, since lemon and lime is an acidic profile by nature
• are pregnant or have a health condition that affects how you tolerate nicotine, and have not spoken to a healthcare professional

There is also a middle group: people who like the idea of this flavour but find 20mg too strong. For them, the sensible move is to look for the same flavour at a lower strength if the range offers it, or to choose a different bottle at 10mg. It is better to buy the right strength than to try to adapt to the wrong one.

For people replacing a disposable, a refillable system takes a little getting used to. You need to learn to fill a pod, to prime a coil and to charge a battery. None of this is difficult, and the how-to-use section below walks through it step by step. The upside is that once your device is set up, you can change flavour as often as you like by buying a new bottle rather than a whole new product.

It also suits adults who care about waste. A refillable pod kit and a bottle generate far less packaging and electrical waste per puff than a stream of single-use devices, provided the bottle, device and batteries are recycled responsibly at the end of their life.

How to fill and use a 10ml nic salt bottle

Filling a pod is simple once you have done it a couple of times. The steps below apply to most refillable pod kits, but your device manual always takes priority if it differs.

• Step 1: Make sure the device is switched off, or at least not being fired accidentally. Remove the pod or open the tank according to your manual.
• Step 2: Wash and dry your hands. Nicotine e-liquid can irritate skin, and it is best to avoid contact.
• Step 3: Press down and twist the child-resistant cap to open the bottle. Keep the cap somewhere clean.
• Step 4: Find the fill port, which is often a small rubber or silicone plug on the side of the pod. Open it, then rest the nozzle against the hole.
• Step 5: Squeeze slowly and fill to the maximum line. Do not overfill, and do not cover or flood the central airflow tube, as that is the usual route to leaks.
• Step 6: Close the plug firmly, wipe the pod with a tissue and replace the cap on the bottle.
• Step 7: Let the pod rest for five to ten minutes so the wick can soak up the liquid evenly.
• Step 8: Reconnect the pod, take two or three gentle draws without firing the device if it allows, then vape normally.

A few habits improve the experience. Take draws of two to three seconds rather than long pulls, since this keeps the coil from overheating and gives you better flavour. Pause for several seconds between puffs. Let the device cool down between sessions if you are vaping heavily. Wipe the mouthpiece now and then, because condensation collects there and can make the first puff of a session taste unpleasant.

If your device has adjustable power, start at the low end of the range recommended in the manual and increase in small steps only if the flavour is faint. For most salts, flavour is clearest at modest wattage, and going higher produces a harsher hit rather than a stronger taste.

Store the device upright when not in use, with the airflow clear. If you lay a pod on its side with liquid in the tank, it can leak into the airflow channel or the battery connection. Keep spare pods and the bottle in a cool, dry place.

When it is time to change the pod or coil, empty it first if the manual allows, and pour any leftover liquid into a small container or tissue rather than down the sink. Do not mix this e-liquid with other flavours in the same tank unless you are comfortable with the result. Mixing is possible, but the strength and flavour will change, and you lose the ability to track how much nicotine you are using.

Troubleshooting common problems

Most problems with refillable devices come down to the same handful of causes. Here are the ones people run into most often with a nic salt, and the usual fix for each.

• Burnt or acrid taste: the wick is dry or the coil is worn out. Check the liquid level, prime a new coil properly and replace the pod or coil if the burnt taste continues. Taking shorter draws also helps.
• Weak or flat flavour: usually a tired coil, a low battery or flavour fatigue. Charge the device, take a few minutes' break and replace the coil if it has been in use for more than a week or two.
• Leaking from the pod: often caused by overfilling, a loose fill-port plug or squeezing the bottle too hard. Fill only to the line, press the plug in firmly and wipe the pod before reconnecting.
• Gurgling or spitting: there is condensation or excess liquid in the airflow path. Remove the pod, blow gently through the mouthpiece to clear it and wipe it dry.
• Liquid in the mouth: this is a flooded coil. Remove the pod, clear the airflow tube and let the device rest for a few minutes.
• Sore throat or cough: the strength may be too high for you, the wattage may be too high or your draws may be too long and fast. Lower the power, try shorter puffs and consider a lower strength.
• Dry hits: a dry hit is a hot, scratchy puff with little vapour, caused by a wick that has not soaked up enough liquid. Stop firing immediately and let the coil saturate.
• Dark or sticky residue on the coil: a normal sign of ageing. Replace the coil.

If a new bottle tastes different from what you expected, give it a few days. Flavours often settle after the first fill, and your palate may also be tired from a previous liquid. If you are switching from a sweeter flavour, citrus will taste sharper than you remember at first.

Citrus liquids can sometimes separate slightly after long storage, producing a faint colour change or a light sediment. A gentle shake of the sealed bottle before use is usually enough. If the liquid smells off, looks cloudy or tastes very different, stop using it and get in touch with us.

Finally, if your device simply refuses to fire, the problem is almost certainly the hardware rather than the liquid. Check that the pod is seated properly, the contacts are clean and the battery has charge. Wipe the contacts with a dry cotton bud and try again.

Storage, safety, UK rules and recycling

Nicotine e-liquid is a regulated product, and a few rules and habits are worth knowing, particularly for anyone coming from disposables.

UK rules in brief. Nicotine e-liquid in the UK is limited to a 20mg/ml maximum strength and a 10ml maximum bottle size for refillable products, with pod and tank capacities limited to 2ml. Bottles must be child-resistant and tamper-evident, and must carry health warnings. You must be 18 or over to buy. Because of these rules, you will not find a legal nicotine salt stronger than 20mg/ml on the UK market, and you should be sceptical of any seller claiming otherwise.

Storage.

• Keep the bottle upright, capped and out of direct sunlight and heat.
• Store it in a cool, dry place away from children, pets and anything that might be mistaken for a drink.
• Never decant the liquid into an unlabelled container.
• Do not leave bottles in a hot car or on a radiator.

If something goes wrong. Nicotine can be harmful if swallowed or absorbed in quantity, and a full 10ml bottle at 20mg/ml holds a significant amount. If liquid is swallowed, or if a child or pet has had access to it, get medical help urgently: call 999 in an emergency or NHS 111 for advice. If liquid gets on your skin, wash it off with soap and water. If it gets in your eyes, rinse with clean water for several minutes and seek advice.

Recycling. Empty bottles should not be thrown away carelessly. Once the bottle is completely empty, check with your local council about whether it can go into household plastic recycling, as practice varies. Many vape retailers and household waste recycling centres also accept empties. Devices, pods with electronics and batteries are electrical waste and must never go into general rubbish or standard recycling. Hand them in at a household waste recycling centre or at a retailer with a take-back scheme, and use the council's online locator to find a drop-off point near you.

These rules exist for good reasons. Lithium batteries that end up in bin lorries cause fires, and liquid that goes down drains is not something wastewater treatment is designed to handle. Disposing of the pieces properly takes a few minutes and avoids both problems.

Age verification. We take age checks seriously, as the law requires. Expect to confirm your age at checkout and, on delivery, to be asked to prove it if the courier requests it.

Value for money and honest comparisons

At £1.10 for 10ml, the cost works out at around 11p per millilitre. Based on the earlier estimate of 150 to 250 puffs per millilitre in a typical pod kit, that is a very low cost per puff compared with a single-use disposable. It is a realistic comparison because the bottle replaces several disposables, not just one. The main caveat is that you need a refillable device to use it, so the first purchase costs more than a single disposable would. After that, the running cost is a small fraction of the disposable habit.

Here is how the maths looks for a moderate user going through roughly 1.5ml to 3ml of liquid a day. A 10ml bottle lasts around three to seven days. Over a month, that is somewhere between four and ten bottles, depending on your pace. The exact figure will depend on your device, your puff length and your coil condition, so treat it as a planning guide and not a promise.

How it compares with other ranges. Lemon and lime nic salts are available from many brands, including established lines such as Elf Liq, IVG and Hayati, along with a long list of smaller labels. Honest points of comparison:

• Price: the entry price here is low, which makes it easy to try. Some larger brands charge more per bottle, though they may also offer multibuy bundles that bring the unit price down. Compare per-millilitre cost rather than per-bottle cost.
• Range size: some competitor lines have a much larger catalogue of flavours and strengths, including 10mg and 5mg options for most of them. If you want to rotate through many flavours in one brand, a wider range may suit you better.
• Flavour style: citrus nic salts from different brands tend to fall into two camps, either sweeter and soda-like or sharper and more zesty. This bottle aims for a drink-style citrus with a lime finish. Whether you prefer it to another brand is a matter of taste, and we would not claim it beats every rival.
• Strength choice: this listing is 20mg only. If you need a lower strength in the same flavour, check what the range offers or choose a different bottle.

Versus shortfills. A 50ml or 100ml shortfill is usually cheaper per millilitre, but it is a different product for a different device. Shortfills are larger bottles of nicotine-free liquid, usually high in VG, with room left over for a nicotine shot, and they are intended for sub-ohm tanks. They are generally not designed for pod kits made for salts.

Versus disposables. With disposables now banned for sale in Great Britain, the comparison is mostly historical, but it shows why a refillable setup works out cheaper over time and produces less waste. If you are weighing up where to spend your money, a decent pod kit and a few bottles will go a lot further than a stack of single-use devices ever did.

In short, this is a low-cost, citrus-flavoured, high-strength salt for people who already know they want 20mg and own a suitable device. If that describes you, it is a sensible bottle to have. If it does not, there are better matches elsewhere.
