Convinced my mate to switch too
Honestly, I was unsure at first but this has been great. Flavour is strong and lasts the full session. No complaints at all.
DeliciuThe Blueberry Sour Raspberry Deliciu Nic Salt by Vaporesso 20mg by Deliciu in Blueberry Sour Raspberry at 20mg. Free UK delivery over £20, same-day dispatch on weekday orders before 4pm.
Deliciu Nic Salt by Vaporesso in Blueberry Sour Raspberry is a bottled nicotine salt e-liquid built for refillable pod kits. It comes in the standard UK format: a 10ml bottle at 20mg/ml nicotine, which is the maximum strength allowed for e-liquid sold in this country. That works out at 200mg of nicotine across the whole bottle, or roughly 40mg in a 2ml pod filled to the line. The flavour combines ripe blueberry, a tart raspberry middle and a sour finish, and it is tuned for the slow, mouth-to-lung style of draw that pod devices encourage.
Vaporesso is best known as a hardware maker, and its XROS family of pod kits is the obvious thing to put this liquid in, but nothing about the bottle ties you to one brand. Any pod system or low-power refillable device that accepts coils in the 0.6 to 1.2 ohm range is a sensible home for it. What you should not do is pour 20mg nic salt into a high-power sub-ohm tank, and the sections below explain why.
The UK context matters here. Single-use vapes were banned from sale across the UK from 1 June 2025, so the shelf of pre-filled throwaways that many people used to rely on for fruity flavours has gone. The practical alternatives are a rechargeable pod kit with replaceable pods, or a reusable device that you fill yourself from a bottle like this one. Refilling costs less per day, creates far less waste, and lets you choose your own strength instead of being locked into whatever was printed on the packaging. One device lasts for months or years, and a single 10ml bottle replaces what used to be several disposables.
Key facts at a glance
This guide walks through how the liquid tastes and performs, what to pair it with, how to choose a strength, how to fill and look after your device, what to do when something goes wrong, and how it stacks up on cost and against similar blueberry and raspberry nic salts. It is written to help you decide whether this bottle is right for you, including the cases where it is not.
The name tells you the structure, and the flavour follows it in three stages. On the inhale you get blueberry first. It reads as dark and jammy rather than as a pale candy blueberry, with a slightly floral quality that suggests the fruit rather than a sweet. The raspberry arrives mid-draw, brighter and more acidic than the blueberry, and it is the part that stops the flavour from feeling flat. On the exhale the sour note lands, a gentle pucker at the sides of the tongue that fades within a second or two, leaving a clean fruity aftertaste instead of a heavy sugary coating.
Sweetness sits at a medium-to-high level. The sour edge is doing real work here: it cuts through the sugar and keeps the liquid from becoming cloying over a long session. If you have ever eaten a blueberry sweet and a raspberry sour sweet back to back, the idea is similar, with the blueberry carrying the body and the raspberry carrying the sharpness. Nothing in the name suggests a menthol or cooling element, so expect a fruit-forward liquid rather than an ice one.
How power and temperature change the taste
Because nicotine salts are formulated to be smooth at high strengths, there is less harshness masking the flavour than you would get from the same strength in a freebase liquid. That means subtle differences between devices and coils show up more than you might expect, and it is worth trying a few power settings if your kit allows it.
A caveat worth stating plainly: taste is subjective, and sour flavours divide opinion. If you dislike tart sweets, the exhale on this liquid may come across as sharp rather than pleasant. Sour profiles can also tire the palate over a long day, a form of flavour fatigue that vapers sometimes call vaper's tongue. If the flavour starts to fade, rinse your mouth with water, take a short break, or switch to a different flavour family for a day. Citrus drinks and strongly flavoured coffee tend to blunt fruit liquids, so water is the better companion.
A 20mg nic salt behaves differently from the freebase nicotine most people associate with older tank setups. Nicotine salts are made with an acid component that lowers the pH of the vapour, which makes high strengths noticeably gentler on the throat. The result is a quick, satisfying nicotine delivery without the harsh scratch that a 20mg freebase liquid would produce. The trade-off is that the nicotine arrives efficiently, so a few draws go a long way and there is little reason to chain vape.
In a pod kit running at around 10 to 15 watts with a 0.8 or 1.0 ohm mesh coil, expect a compact, dense vapour cloud rather than a large one. This is a mouth-to-lung liquid, not a cloud-chasing one. Draws of two to four seconds, taken slowly, give the best flavour and the most consistent throat sensation. Faster, harder pulls tend to cool the coil, thin the flavour and increase the chance of liquid being drawn into the mouthpiece.
Working out how long a bottle lasts
Performance holds steady across the life of a coil, then falls away over a short stretch rather than gradually. Typical signs are muted flavour, slightly warmer vapour and a faint burnt note at the end of a draw. When that happens, the cure is almost always a new pod or coil, not a different liquid.
Because this is a sweet, fruit-based liquid, it leaves slightly more residue on a coil than a plain tobacco or menthol liquid would. That does not make it a poor choice, but it does mean you should expect to replace coils a little more often and keep the mouthpiece and contacts wiped clean.
Because this is an e-liquid rather than a device, build quality comes down to the bottle, the cap, the labelling and how the liquid is packed. UK rules require nicotine e-liquid to be sold in containers no larger than 10ml, with a child-resistant and tamper-evident closure, and with a clear nicotine warning on the label. Those requirements shape what you receive: a small plastic bottle with a thin nozzle and a cap that needs a firm press-and-turn to open.
Most bottles in this format use a soft plastic body that can be squeezed gently to dispense liquid, topped with a narrow nozzle designed to fit the fill ports on pod cartridges. That narrow tip matters. Pod fill holes are small, often just a few millimetres across and sometimes sealed with a silicone plug, so a wide dropper is a recipe for spills. A fine nozzle lets you place liquid against the pod wall and control the flow drop by drop.
What to check when your bottle arrives
Storage matters as much as build. Keep the bottle upright, tightly closed, away from direct sunlight and heat, and well out of reach of children and pets. A parked car on a warm day or a windowsill in direct sun is a poor place to leave e-liquid, because heat and light degrade flavour and can darken the liquid over time. A slightly deeper colour after a few weeks is normal for many nicotine liquids and is not a safety issue by itself, but a change in smell or a noticeably harsher taste is a good reason to stop using that bottle.
Recycling is straightforward for the bottle itself. Once it is completely empty, check with your local council about whether empty rigid plastic bottles of this kind can go into household plastic recycling, since rules differ between areas. Never pour leftover liquid down a drain or into the bin; seal the cap and take it to a household waste recycling centre if you need to dispose of unused liquid.
The liquid does not need charging, but the device you put it in does, and the battery you choose has a direct effect on how this flavour behaves. Slim pod kits generally use batteries in the region of 800 to 1,000mAh, which is enough for a day or more of moderate use at the low wattages this liquid is designed for. Charging is usually done over USB-C, and a full charge on a pod kit of this size commonly takes somewhere around an hour, though your manual is the final word on both capacity and charge time.
A 2ml pod filled with 20mg/ml liquid holds about 40mg of nicotine, and a 1,000mAh battery will typically outlast a pod or two on a typical day. That pairing is by design: the pod empties at around the same rate as the battery, so a morning fill and an evening charge fit naturally into a routine. If you find the battery dying long before the pod empties, check the power setting and the coil resistance, because a lower-resistance coil at higher power drains the battery much faster.
What to look for in a compatible device
Charging safety is simple but worth repeating. Use the cable that came with the device or a reputable replacement, avoid charging overnight on a soft surface like a bed or sofa, and do not leave a charging device unattended near anything flammable. If a battery swells, overheats, smells odd or is visibly damaged, stop using it.
When a device or battery reaches the end of its life, it must not go in your general waste bin. Lithium cells are a fire risk in bin lorries and recycling plants. Take old devices, batteries and used pods to a household waste recycling centre or a retailer drop-off point that accepts small electrical items, and tape over exposed battery terminals if you can. Choosing a rechargeable kit over a throwaway is the single biggest reduction in vaping waste you can make.
Most modern pod systems use mesh coils rather than the older round-wire coils. A mesh coil is a flat, perforated sheet of resistance metal that sits against the cotton wick, and it offers a larger heating surface than a wire wrapped round a wick. In practice that means faster ramp-up, more even heating and a more consistent flavour from the first draw to the last. For a layered fruit liquid like this one, the even heat helps the blueberry, raspberry and sour notes come through distinctly rather than blurring together.
Resistance is the number that decides how a coil behaves with a given liquid. Roughly speaking, a higher resistance coil draws less power, produces less vapour and delivers a tighter draw, which suits a high-strength nic salt. A lower resistance coil draws more power, heats faster and produces more vapour, which is why sub-ohm devices are paired with low-strength liquids rather than 20mg salts.
Choosing a coil for this liquid
Coil lifespan depends on how you vape and on the liquid. Sweet and fruit-heavy liquids leave more residue on a coil, so expect a coil to last somewhere between one and two weeks of regular use rather than a month. Habits that extend life include priming new coils properly, avoiding chain vaping, keeping the pod above a quarter full, and not running the device at the top of its power range.
A few warning signs show a coil is on its way out: the flavour thins or tastes slightly burnt, the vapour becomes warm and thin, or a gurgling sound appears when you draw. Replacing the pod or coil resets all of that. Do not try to push a failing coil by turning the power up, because that accelerates the burn and wastes liquid.
One last point on wicking. The cotton inside a coil needs time to saturate with liquid, especially with thicker mixes. If you fire a freshly filled pod immediately you risk a dry hit, which scorches the cotton and permanently spoils the coil, so give it a few minutes first.
The UK limit on nicotine strength in e-liquid is 20mg/ml, and this bottle sits exactly at that ceiling. It is the highest strength available, which makes it a deliberate choice for a particular type of user rather than a sensible default for everyone. Picking the right strength matters because too little leaves you reaching for the device constantly, while too much brings headaches, nausea, a racing heart and a general jittery feeling.
Nicotine salts feel gentler than freebase at the same number, so 20mg nic salt is not directly comparable with a 20mg freebase liquid, even though the label figure is identical. The smoothness can hide how much nicotine you are taking in, which is why paying attention to your own response matters more than the number on the bottle.
A rough guide used across the UK vape trade
These bands are starting points, not prescriptions. If you feel lightheaded, queasy, sweaty or shaky after a few draws, the strength is probably too high for you or your device is delivering too much, so lower the power, choose a higher-resistance coil or move to a lower-strength liquid. If you keep wanting to vape and still feel cravings, the strength may be too low, but also consider whether your airflow is too open or your battery is struggling.
Some simple arithmetic helps. A user taking three millilitres a day of 20mg/ml liquid is consuming 60mg of nicotine daily from the device. That is a lot of nicotine for someone who smoked ten cigarettes a day, and it explains why many switchers end up stepping down after a few weeks. Treat 20mg as a tool for getting off cigarettes, not a place to stay forever.
If you want to stop nicotine altogether, free local stop-smoking services and your pharmacist or GP can help you plan a taper. Nicotine is addictive, and this product is intended for adult smokers, not for anyone who has never smoked.
Deliciu Blueberry Sour Raspberry 20mg is aimed at a fairly specific person: an adult smoker or established vaper who wants a fruit-forward flavour, uses a low-power pod device, and wants the strongest nicotine level the UK permits. If that is you, the bottle makes sense. If not, there are better options, and it is worth being honest about that.
Good fit
Not a good fit
There is also the question of experience. If you have never vaped before, 20mg nic salt in a powerful device is a hard first step. New users do best starting with a simple pod kit, a modest coil such as 1.0 ohm, and short, gentle draws while they learn how their body responds. A vape shop can help you choose a first device if you are unsure.
Finally, consider your goals. If you are trying to cut down nicotine over time, 20mg is a starting point, not a destination. Many people begin at 20mg for a few weeks and then drop to 10 or 12mg once cigarette cravings fade, so it is worth keeping a lower-strength bottle in mind for the next step.
Using nic salt in a pod device is simple once you know the steps, and getting them right prevents most of the problems covered in the next section. Follow the sequence below and adapt the details to your own device manual.
Step by step
Everyday handling tips
Keep the bottle and any spare pods out of children's reach at all times. Nicotine liquid can be harmful if swallowed or absorbed through the skin. If it gets on your hands, wash it off with soap and water; if it gets in your eyes or someone swallows it, seek medical help straight away.
Most issues with nic salt pod setups come down to a handful of causes, and almost all of them are fixable in a minute or two. Work through the list below before assuming the liquid or the device is faulty.
If you have tried all of this and the problem persists, contact us with your order number, a description of what is happening and a photo of the bottle batch code. We can then check whether it is a batch issue, a compatibility issue with your device, or a case for a replacement.
A final reminder on safety: if a device overheats, produces smoke, makes a hissing noise or the battery swells, stop using it immediately, move it somewhere safe away from flammable materials and do not charge it again. Report the fault to the manufacturer or retailer you bought it from.
Judging value on an e-liquid is a matter of working out what you actually pay per millilitre and how many millilitres you get through each day. The sums are simple enough to do yourself, and they put the price of a refillable setup in context compared with the single-use products it replaces.
The basic arithmetic
Because this is a 20mg liquid, you will generally use less of it per day than you would of a lower-strength liquid. Higher strength means fewer millilitres to satisfy the same craving, which helps the per-day figure. It also means a 10ml bottle goes a long way for a lighter user.
Against disposables, which are no longer available in the UK, the comparison is less about price and more about what you can still buy. Single-use products always cost more per puff than a refillable system once you account for the device being thrown away each time, and their waste footprint is considerably greater. A pod kit, a handful of coils and a few bottles of liquid add up to much less over a month.
Against larger formats such as 50ml and 100ml shortfills, a 10ml nic salt is more expensive per millilitre, but the formats are not directly comparable. Shortfills are designed for high-power sub-ohm devices at low strengths, and you add nicotine shots yourself. If you use a pod kit and want a ready-to-use liquid at 20mg, a nic salt bottle is the straightforward choice, with no mixing, no sums and no risk of getting the strength wrong.
What you get for the money is a liquid with a distinct, layered flavour, a smooth throat hit at high strength and a bottle sized for UK rules. What you do not get is a bargain-bin price per millilitre, a large-volume discount or a cooling variant. Whether that represents good value depends on how much you vape, how much you care about flavour quality and whether the sour berry profile suits you. For smokers moving away from cigarettes, the saving over a pack-a-day habit is considerable even at a modest price per bottle.
Blueberry-and-raspberry is a crowded flavour family in UK vaping, and there are plenty of alternatives at the same 10ml size and the same 20mg ceiling. Brands such as Elfliq, IVG Salt, Dinner Lady and Nasty all sell nic salts in 10ml bottles up to 20mg/ml. Because strength and bottle size are fixed by regulation, the real differences come down to flavour tuning, price per millilitre, range depth and availability. Here is how to think about them fairly.
Where this liquid is a good choice
Where alternatives may suit you better
It is also worth being clear about what comparison cannot tell you. Flavour is personal, and a liquid that tastes excellent to one person can taste artificial to another. Two liquids with the same name from different brands can differ more than you would expect, since there is no standard recipe for blueberry sour raspberry. The only reliable test is to try a bottle in your own device.
If you are weighing this against other options, a sensible approach is to match on the things you can control: pick the strength that suits your smoking history, check that your coil is in the 0.6 to 1.2 ohm range, and then choose on flavour. Where this liquid lands for you will depend on how much you value that sour edge. For adult smokers who want a tart berry flavour in a low-power pod kit, it is a reasonable, well-matched option, and for anyone else, a different profile may suit better.

Deliciu nic salts (a Vaporesso-affiliated range) deliver clean fruit and menthol flavour profiles in 10ml bottles — a solid partner for Vaporesso refillable kits.
20mg/ml is the maximum strength allowed in UK e-liquid and is generally suited to people who smoke around a pack a day or more using a tight-draw pod kit. Lighter smokers, or anyone who feels dizzy or sick after a few draws, will usually be more comfortable with 10 to 12mg. Check whether a lower-strength version of this flavour is listed on our site before you order.
The liquid itself needs no charging, but the pod device you put it in does. Most pod kits charge over USB-C and take around an hour for a full charge, though your manual gives the exact figure. Use the supplied cable, avoid charging on soft surfaces and never leave a charging device unattended.
It is not recommended. A 20mg nic salt is designed for mouth-to-lung pod kits with coils between 0.6 and 1.2 ohm at low power. In a high-wattage sub-ohm device it delivers far too much nicotine per puff and can cause nausea and dizziness.
As a rough guide, a pod device uses around 250 to 300 puffs per millilitre, so a 10ml bottle gives roughly 2,500 to 3,000 puffs. A moderate user at one to two millilitres a day will get five to ten days, while a heavier user may finish it in around three. Your draw length, power setting and coil condition all change the figure.
Yes, but not by topping up on top of an existing flavour. Empty the pod, rinse it with cool water, let it dry fully and ideally fit a fresh coil so the old flavour does not bleed into the new one. Do not mix this liquid with other e-liquids or nicotine shots in the pod, since that makes the final strength unpredictable.
Any refillable pod kit or low-power device that accepts coils in the 0.6 to 1.2 ohm range will work, including Vaporesso's XROS family and many other brands. The pod needs a fill port wide enough for a fine-tipped 10ml bottle. Check your device manual for the recommended liquid type before filling.
It suits adult smokers and established vapers who want a sour berry flavour and a high nicotine strength in a pod kit. It is not for anyone under 18, non-smokers, people who dislike sour flavours, or those using sub-ohm devices. If you are pregnant or have a heart condition, speak to your GP or midwife before using any nicotine product.
Single-use vapes were banned in the UK from 1 June 2025, so the real comparison is between a refillable pod kit and the old habit. Refilling from a 10ml bottle generally costs much less per day than throwaways, and a reusable device creates far less waste. You pay for a device and the occasional coil, but a bottle plus a kit works out cheaper over a month.
We deliver across the UK, and delivery options and cut-off times are shown at checkout and on our delivery page. Nicotine products can only be sold to people aged 18 and over, so we carry out age verification on every order and the courier may ask for ID at the door.

Excellent all round. Will absolutely be ordering again. Customer service was helpful too.
Can't fault it. Quality is there, flavour is there, delivery was quick. What more could you want.
Picked this up on the multibuy deal and I'm stocked up for a while. Flavours are all on point.
Great product for the price point. Works exactly as advertised. No surprises, just a solid vape.
Not too strong, not too mild — just right. Good for all day use without being overpowering.
