Lost Mary Nic Salts Sour Red is a 10ml nicotine salt e-liquid from Lost Mary, sold in 5mg, 10mg and 20mg strengths for refillable pod devices. It is a bottle of liquid, not a finished device. There is no battery, no coil and no pod inside the box, so you need compatible hardware to use it. That distinction matters because the Lost Mary name is better known for prefilled kits, and plenty of shoppers land on a page like this expecting a ready-to-vape product. If that is you, read on, because the bottle route is cheaper per millilitre and gives you more control over how and what you vape.
The format makes more sense now than it did a few years ago. Single-use disposable vapes have been prohibited for sale in the UK since 1 June 2025, which pushed adult smokers and vapers towards refillable pod kits and rechargeable devices. A nic salt bottle is the natural fuel for those systems. You fill a small pod or tank, vape it down, refill it, and the only thing you throw away is a small empty bottle rather than a whole device with a lithium battery inside it. That is better for your wallet and considerably better for the waste stream.
Sour Red sits in the sweet-and-tart corner of the Lost Mary nic salt range. Rather than naming one specific fruit, the label points to a red-fruit candy profile with a sharp, sour finish. We go through what that means in the flavour section below, including the honest caveat that taste is personal and a sour flavour is not for everybody.
The key facts at a glance:
Sales are strictly 18+, every order is age-checked before it ships, and nicotine is an addictive substance. These products are intended for adult smokers and existing vapers, not for people who have never used nicotine.
Because this is a liquid, performance depends on the device you pair it with, but the liquid itself sets the character of the vape: throat hit, vapour density, how quickly it wicks and how consistently it tastes from the first fill to the last. Nic salts are formulated differently from traditional freebase nicotine. The nicotine is bound with an organic acid, which lowers the pH and makes the vapour noticeably smoother at higher strengths. That is the whole reason a 20mg nic salt feels manageable in a small pod kit where a 20mg freebase liquid would be harsh enough to make most people cough.
In practice you can expect a firm but rounded throat hit at 20mg, a lighter and softer hit at 10mg, and a very gentle one at 5mg. Vapour volume is moderate. Nic salts are designed for low-wattage mouth-to-lung use, so you will not produce the big clouds associated with sub-ohm tanks, and you should not try to. Pushing a nic salt through a high-power device burns through liquid quickly, adds heat that dulls the flavour, and delivers a lot more nicotine per puff than the strength on the bottle suggests.
Wicking is the other performance point worth knowing. Sour and fruit-candy liquids carry sweeteners and flavour concentrates that can leave a sticky residue on a coil. A liquid that is balanced between vegetable glycerine and propylene glycol (check the bottle label for the exact split on your batch, as it can vary) wicks quickly through the cotton in a mesh or standard pod coil and keeps dry hits to a minimum, provided you let the pod saturate after filling. We cover priming in the how-to-use section.
How far does a bottle go? Treat the following as a rough guide rather than a promise, because puffing habits vary enormously:
Consistency from the first refill to the fifth is generally good with this sort of liquid, with one exception. Flavour fade, sometimes called vaper's tongue, can make a sour liquid taste muted after a few days of exclusive use. That is your palate adapting rather than the liquid failing, and rotating to a second flavour for a day or two usually resets it.
Sour Red does not name a specific fruit, so it is worth describing what the profile is aiming for. The direction is red fruit candy: think the sweet, slightly syrupy character of red berry sweets, finished with a tart, mouth-puckering edge like the sour sugar coating on a fruit chew. It is a candy interpretation rather than a realistic fruit one, which means sweetness and sourness do most of the work and there is little of the natural, juicy complexity you would get from, say, a fresh strawberry or raspberry.
On the inhale, expect the sweet red-fruit note to arrive first. The tartness builds through the middle of the puff and reaches its peak on the exhale, where a sharp, slightly acidic finish lingers on the tongue for a moment. Some people read that sharpness as a faint cooling effect. To be clear, there is no menthol or ice component in the name or the profile. If you want a genuinely cold finish, you would look at the ice variants elsewhere in the Lost Mary range rather than expecting Sour Red to deliver one.
A few honest points on how this style behaves:
Sour Red pairs sensibly with a rotation partner from a different family. A cool mint or a creamy dessert style gives your palate a break from tartness and keeps both flavours tasting fresh for longer. Many adult vapers settle into a two or three bottle rotation for exactly this reason.
With a liquid, build quality comes down to the bottle, the cap and the labelling rather than anything electronic. Lost Mary Nic Salts ship in a 10ml plastic bottle with a narrow filling nozzle. That nozzle is not a styling choice: UK rules require nicotine e-liquid bottles to be designed to refill without spills and leaks, and a slim tip lets you aim accurately at the small fill port on a pod without flooding the airflow channel.
The cap is child-resistant and tamper-evident. You press down and turn to open it, and the first twist breaks a ring or seal that shows the bottle has not been opened before. This is a legal safety feature and it is worth using as intended. Nicotine liquid is toxic if swallowed, and a half-open cap defeats the purpose. Always close the cap fully after every refill and keep bottles out of reach of children and pets.
The label carries the mandated nicotine health warning, the strength in mg per ml, the volume, the flavour name, batch information and ingredients. Take a moment to read it before you buy and again when you open the bottle. In particular, check:
On material quality, the plastic is flexible enough to give a controlled squeeze, which helps when you are filling a small pod, but it is also soft enough that you should avoid squeezing hard. A gentle, slow squeeze and a pause before you pull the nozzle away prevents the drip that tends to collect on the tip and run down the outside of the bottle.
Stock is sourced through UK distribution, so packaging and labelling follow UK requirements. We cannot take opened liquids back, which is why you should inspect the bottle and seal when it arrives and tell us about any fault straight away.
For disposal, empty bottles should be rinsed only if your local council guidance says so, and then placed in the recycling stream your authority specifies for small plastics. Check your council website, as rules on nicotine-contaminated containers vary by area. Do not put devices or batteries in household bins.
This bottle contains no battery and has nothing to charge. The battery question belongs to the pod kit or device you fill it with, and getting that pairing right makes a real difference to how Sour Red tastes and how long a refill lasts.
Most refillable pod kits designed for nic salts carry batteries somewhere between 400mAh and 1,000mAh. At the low-wattage settings nic salts need, typically around 8 to 15 watts, a 500 to 800mAh battery generally lasts a full day for a moderate user and two to three days for someone who vapes lightly. Larger batteries make more sense for heavy users or people who spend long stretches away from a socket. Do not assume higher mAh means more power. Battery capacity controls how long the device runs between charges, not how hard it hits.
Charging habits protect both the device and you:
Recycling matters here. Vape devices and batteries are electrical waste. In the UK you should take them to a household waste recycling centre or a retailer take-back point, and never put them in general waste or kerbside recycling, where crushed lithium cells have caused fires in collection vehicles. Retailers that sell vaping hardware are obliged to accept old devices back, and many council sites have a dedicated small electricals bin. A refillable kit helps enormously on this front. One device used for a year replaces dozens of single-use units that would otherwise end up in landfill.
If your current battery is struggling to get through the day, it may be a sign the device is nearing the end of its life rather than a problem with the liquid. Weak batteries often cause weak vapour, which is easy to mistake for a flavour issue.
The coil is where the liquid becomes vapour, and it is the component that most affects how Sour Red tastes. Nic salts are built for coils in the range of roughly 0.6 to 1.2 ohms, used at low power. That covers the majority of refillable pod systems sold in the UK, including both standard wire coils and the mesh coils that have become common in recent years.
Mesh coils use a flat, perforated sheet of resistance material rather than a thin round wire wound around cotton. The larger surface area heats the liquid more evenly, which tends to give more consistent flavour and less chance of a burnt hit as the pod runs low. Standard round-wire coils are simpler and cheaper but can produce slightly sharper, less even vapour. Either works well with a nic salt. If you have a choice, mesh generally renders sweet and sour flavours more cleanly.
Points to bear in mind when matching Sour Red to a coil:
Some pods are sealed and non-replaceable, with the coil built into the pod itself. These are convenient because you swap the whole pod, but they are less economical than systems where only the coil head changes. If you are buying a kit specifically to use with bottled nic salts, look for one with an easily accessible fill port, a pod capacity at or under the 2ml UK limit, and replacement coils that are widely stocked.
It also helps to know that the liquid, not only the coil, shapes how quickly a pod gunks up. A fresh coil primed correctly and run at the right wattage with a balanced nic salt like this one should deliver reliable flavour for most of its life.
UK rules cap nicotine in vaping products at 20mg per ml, and that ceiling applies across the board, including to the prefilled and disposable products that used to dominate the market. No legitimate UK seller can supply more, so if you see a bottle claiming a higher figure, treat it with suspicion. Lost Mary Nic Salts Sour Red is available at 5mg, 10mg and 20mg, which means that for UK buyers, the choice is really about how far down you want to go.
Here is how the three strengths tend to work in practice:
A useful rule of thumb is to match your starting strength to how much you smoked, then adjust. If you vape constantly and still feel unsatisfied, you may be on too low a strength. If you get a harsh throat hit, a racing feeling or mild nausea, you may be on too high a strength. Neither is a failure, just a sign to adjust.
Sour flavours deserve one extra note. Acidic flavouring adds its own sharpness on top of the nicotine hit, which is why many people pick one strength lower for a sour liquid than they would for a smooth dessert flavour. If you normally vape 20mg in a creamy flavour, consider trying Sour Red at 10mg first.
Bear in mind that nicotine strength and nicotine intake are not the same thing. A higher-powered device, longer puffs and more frequent use all increase intake regardless of what the bottle says. The aim for adult smokers is generally to switch completely, then step the strength down over time if you choose to. The NHS notes that vaping is substantially less harmful than smoking but is not risk free, and that people who have never smoked should not start. If you want help quitting, your local stop smoking service can offer support alongside vaping.
No flavour suits everyone, and a sour candy profile is more divisive than most. Here is an honest breakdown.
Good fit:
Probably not for you:
It is also worth being realistic about the learning curve. If you have only ever used prefilled devices, filling a pod will feel fiddly for the first couple of attempts. It does not take long to get the hang of it, and most people are comfortable after a refill or two.
Finally, think about where you will use the product. Sour Red is a loud, bright flavour and its sweetness is noticeable on the breath for a moment after you exhale. That is rarely an issue, but it is something to keep in mind in shared spaces. Many adult vapers are considerate about where and when they vape, and the same common courtesy applies to a fruity candy flavour as to any other.
Using a bottled nic salt properly takes a few minutes of care and pays back in cleaner flavour, fewer leaks and longer coil life. Follow these steps with a typical refillable pod device. Always check your device manual too, as filling mechanisms differ.
Technique matters as well. Nic salts are made for mouth-to-lung vaping. Draw into your mouth for a second or two, pause, then inhale into your lungs. Slow, steady draws let the coil heat evenly and keep the vapour smooth. Long, hard pulls, or chain vaping with no pause between puffs, overheat the coil and cause a harsh, hot hit.
Sensible habits to build in:
Most problems with bottled nic salts come down to a handful of causes, and almost all are fixable without replacing anything. Here is what to check.
If you work through this list and still have a problem, contact us with your order number and a description of the fault. Faults and picking errors are resolved without argument. Remember that opened liquids cannot be resold, so be sure to inspect the bottle and seal when it arrives.
Value is where bottled nic salts earn their place. At the time of writing, Lost Mary Nic Salts Sour Red is listed at £2.89 for a 10ml bottle. That works out at roughly 29p per millilitre. The 5 for £10 multibuy, if you take advantage of it, brings the price to £2.00 a bottle, or 20p per millilitre, and you can mix flavours within the offer. Always check the live listing, as prices and offers can change.
To put that in context, a 2ml prefilled pod pack commonly costs several times as much per millilitre as bottled liquid, because you are paying for the convenience of the sealed, ready-to-use format. The trade-off is that bottles need a refillable device and a few minutes of effort per refill. For anyone who vapes daily, that effort pays for itself quickly.
Here is a worked example for a moderate daily user taking around 1.5ml a day, or about 45ml a month:
A heavier user vaping 3ml a day would need around nine bottles a month, which is about £18 on multibuy pricing or £26 at the single price. Even at that level, it remains far cheaper than most other routes to the same nicotine intake.
There is an upfront cost to remember. A refillable pod kit usually costs somewhere between £10 and £25, and you will replace coils as they wear. Those costs are quickly absorbed by the lower per-millilitre price. Treat the hardware as a one-off outlay and the liquid as the true running cost.
Delivery adds little to the equation if you plan your basket. UK delivery is free once your basket reaches £20, and weekday orders placed before 4pm are dispatched the same day. Tracked options are shown at checkout. Because the multibuy bundle sits under the free delivery threshold, either add a second bundle or a small extra item to cross it.
Finally, consider what you are not paying for. With a bottle, you do not pay for a new battery, plastic shell and circuit board every few days. You pay for liquid. That is the cleanest way to look at the value on offer.
A fair comparison needs to say where Sour Red is strong and where other products may suit you better.
Against other Lost Mary Nic Salts flavours. Within the same range you get the same price and format, so the choice is purely about taste. Sour Red is the tangy, candy-led option. The ice variants add a cooling finish, the dessert styles lean creamy and the straight fruit flavours are less acidic. If you find sour too sharp, a gentler fruit flavour from the same line is a low-risk alternative at the same price.
Against other brands' sour fruit nic salts. Several established UK brands, including Elf Liq, IVG, Nasty and Dinner Lady, sell nic salt bottles in similar 10ml formats with their own takes on sour and red fruit profiles. Premium craft brands often cost more per bottle and some deliver more layered, complex flavour. Lost Mary's strengths are price, familiarity and a consistent range. If you are loyal to a flavour you know from another brand, trying a bottle here beside it is the simplest way to judge. Taste is subjective, so we would not claim one is better than another across the board.
Against shortfills and freebase liquids. These are designed for sub-ohm, higher-power devices, come in larger volumes and use lower nicotine strengths, usually 3mg or 6mg once mixed with a nicotine shot, or nicotine-free. They suit a different style of vaping altogether, with bigger clouds and a much softer throat hit. If you use a low-power pod kit, nic salt is the right choice, not a shortfill.
Against prefilled pods and kits. Prefilled products are the most convenient, with nothing to fill and no maintenance. They are also the most expensive per millilitre and generate more waste. Bottles give you more control, a lower running cost and the ability to change flavour without changing hardware.
Against tobacco and mint flavours. If your main aim is to move away from cigarettes, some adult smokers find a tobacco or menthol profile easier to switch to, because it is closer to what they know. Others find fruit flavours help them break the association with smoking. There is no single right answer, and plenty of people mix both styles.
The honest summary is that Sour Red is a sensible, affordable choice for people who like sour candy flavours and own a compatible low-power device. If you are not sure you like the style, buy one alongside a flavour from a different family rather than committing to a large order.

Lost Mary is the sister brand to Elf Bar and quickly became the UK's dominant disposable-successor range — BM6000, Nera 15K and Pro Max 7K sit at the top of nearly every shop's bestseller list. The brand mixes approachable flavour engineering with device formats designed for the post-disposable era.
It comes in 5mg, 10mg and 20mg, and 20mg is the UK legal maximum. Heavier former smokers often start at 20mg, moderate smokers at 10mg, and light users or people stepping down at 5mg. Sour flavours feel sharper than sweet ones, so if you normally vape 20mg you may want to try 10mg first.
You do not, because this is a bottle of liquid with no battery. The charging belongs to the refillable pod kit you pour it into, which usually charges over USB-C using the cable supplied. Do not charge unattended overnight, and take old devices and batteries to a household waste recycling centre or retailer take-back point.
Yes, the Lost Mary Nic Salts range has many other flavours at the same price and in the same strengths, and you can mix flavours within the multibuy offer. To swap flavours in a pod, let it run nearly empty before refilling. For a completely clean switch, fit a fresh coil, as old residue can leave traces of the previous flavour.
A 10ml bottle fills a standard 2ml pod about five times, which works out at roughly 3,000 puffs on the yardstick disposable marketing used. A light user may stretch a bottle over two to three weeks, while a heavier user could finish one in three to seven days. Your device, power setting and habits all change the answer.
Per millilitre, yes. At £2.89 a bottle it costs around 29p per ml, and the 5 for £10 multibuy brings that down to around 20p per ml, which is usually well below the per-ml cost of prefilled pods. You do need a refillable device and the occasional replacement coil, so the saving comes from the running cost rather than the upfront cost.
It suits adult smokers and existing vapers who enjoy sweet and sour fruit flavours and own a low-power pod kit. It is not for anyone under 18, anyone who has never used nicotine, or people who dislike sour or sweet tastes. If you are pregnant, breastfeeding or have a heart condition, speak to a doctor or pharmacist first.
No. It is a nic salt designed for low-power mouth-to-lung pod systems with coils roughly between 0.6 and 1.2 ohms. It is not suited to sub-ohm tanks or high-wattage devices, where it wastes liquid and delivers far more nicotine than intended. Check your device specification before ordering.
Weekday orders placed before 4pm are dispatched the same day, and UK delivery is free once your basket reaches £20. Tracked delivery options and any paid options are shown at checkout. Every order is age-verified before it ships, and orders that cannot be verified are refunded rather than sent.
Because an opened liquid cannot be resold, opened bottles are outside the returns policy. Faults and picking errors are resolved without argument, so check the bottle and its tamper-evident seal when it arrives and contact us promptly with your order number if anything is wrong.
Store it upright, capped, away from heat and sunlight, and out of reach of children and pets. Warmth thins the liquid and is a common cause of leaks. Dispose of empty bottles following your local council guidance for small plastics, and recycle any devices or batteries separately at a proper drop-off point.

Not too strong, not too mild — just right. Good for all day use without being overpowering.
Been using this every day for a couple of weeks now. Lasts well, no issues with leaks or anything.
Smooth throat hit, no coughing fits. Perfect strength for what I was after. Will buy more.
Fast delivery, genuine product, fair price. What more can I say? Already recommended to friends.
Quality feels solid. Doesn't feel cheap like some other brands I've tried. Happy with the buy.
Really pleased with the order overall. Everything arrived as expected, well packed, fast dispatch.
