IVG Nic Salt Sour Green Apple at a glance

IVG Nic Salt E-Liquid Sour Green Apple is a nicotine salt e-liquid with a tart green apple flavour, sold in a 10ml bottle for refillable pod kits and other low-power vaping devices. It belongs to the IVG Salt range, which is built around a simple idea: familiar flavours in a nicotine format that stays smooth at low wattage. Sour Green Apple is the crisp, mouth-watering option in that line-up, aimed at vapers who want a bright fruit flavour with a sharp edge rather than a sweet dessert blend or a cooling menthol mix.

This page goes through what that means in practice. We cover the flavour, how nic salts differ from freebase liquid, how to choose between the available strengths, which devices suit it, how the liquid behaves in the coil, and how to fix the usual problems. We also give an honest read on value, including the situations where another product would suit you better. Where a figure depends on your device or on the exact pack in your hand, we say so rather than guess, because the label on the bottle always has the final word.

Quick facts:

• Product type: nicotine salt e-liquid, sour green apple flavour
• Bottle size: 10ml, the maximum bottle size permitted for nicotine e-liquid in the UK
• Strengths: offered within the UK limit, where 20mg/ml is the legal ceiling; check the variant you select for the exact figure
• Suited to: refillable pod kits and low-wattage mouth-to-lung devices
• Not suited to: high-power sub-ohm tanks, which are built for lower-strength freebase liquid
• Age restriction: sold to adults aged 18 and over only

If you are moving across from a disposable and want to keep the fruit-and-tang style, this is a straightforward way to do it with a refillable device, and the cost per millilitre is usually lower over a month of use. If you have never vaped before, the sections on strength and device choice are the most useful place to start.

Flavour profile: what Sour Green Apple tastes like

Green apple is a flavour most people recognise instantly, and the sour version leans into the tart side of it. On the inhale you should expect a clean, slightly acidic apple note, closer to a crisp Granny Smith than to a red eating apple or a baked dessert apple. The sourness is there to cut through any sweetness and give the vape a mouth-watering quality, the same way a squeeze of lime lifts a sweet drink. On the exhale the apple fades into a softer, lightly sweet finish with a faint tang left on the tongue.

It is worth being realistic about how a sour flavour behaves in e-liquid. Acidic notes are produced with flavour concentrates and sour agents rather than with real fruit, and they are most noticeable on the first few puffs of a fresh coil. Many vapers find that the tartness reads strongest at the start of a session and settles into a rounder apple taste as the coil warms up. If you take long, slow draws the sourness tends to sit further back; short, sharp draws tend to emphasise it.

What the flavour is not:

• Not a menthol or ice flavour. There is no deliberate cooling agent, so the vape feels like fruit rather than frost.
• Not a dessert flavour. Expect no creaminess, candy sweetness or bakery notes.
• Not a candy-sweet apple. It is tarter than a typical sweet apple e-liquid, which suits vapers who find sweet blends cloying after a few hours.

Flavour perception varies from person to person and also changes with device, wattage and even what you have eaten or drunk recently. Coffee and mint can mute fruit flavours, while a glass of water between sessions tends to bring them back. If you find the sourness too sharp, a slightly lower power setting usually softens it, and if you find it too flat, a small step up in power or a fresh coil can bring the tang back.

Nicotine salts explained: why they suit pod kits

Nicotine salt, often shortened to nic salt, is nicotine combined with an organic acid so that it can be inhaled more comfortably at higher strengths. Traditional freebase nicotine is harsher on the throat, which is why freebase liquids are normally sold at 3mg to 6mg for sub-ohm tanks, with 12mg as a common upper level. Nic salts feel smoother at 10mg to 20mg, which is why they became the standard for pod kits and disposables.

There is also a difference in how quickly many people feel the effect. Nic salts are generally described as delivering nicotine to the body more quickly than freebase at the same strength, which is part of why smokers who switch often find them more satisfying at low power. That is a general description of how the format behaves rather than a promise about any one user, and individual response varies with strength, device and inhalation style.

Why this matters for Sour Green Apple:

• Low power needed. Pod kits and other small devices run at modest wattage, and salts are formulated to work well in that range.
• Smoother tart flavour. A sour flavour can feel sharper in a harsh freebase liquid; the smoother feel of a salt helps keep the throat comfortable.
• Small puffs go further. Because salts are satisfying in small draws, a modest device can deliver what a larger setup would at lower strength.

A few points are worth stating plainly. Nicotine is addictive, and nic salts do not change that. These products are intended for adult smokers and existing vapers, not for people who have never used nicotine. They are also not suitable for pregnancy or breastfeeding, or for anyone with a heart condition or other medical concern without advice from a doctor. Salts should not be put in devices designed for freebase, particularly high-power sub-ohm tanks, because the combination of high wattage and high strength delivers far more nicotine than intended and is unpleasant to use.

Choosing a nicotine strength

The most important choice on this page is strength. In the UK, nicotine e-liquid is limited to a maximum of 20mg/ml, and IVG Salt liquids are sold within that limit. The strengths offered are selected on the product page, so check the variant you choose and the label on the bottle when it arrives.

As a guide:

• 10mg/ml. A gentler strength for light or social smokers, for vapers who already use a low-strength liquid and want something a little firmer, and for anyone who finds higher strengths too strong on the throat. It is also the sensible choice if you plan to vape often through the day, because the nicotine intake adds up.
• 20mg/ml. The top legal strength and the usual starting point for people coming off a daily smoking habit, particularly heavier smokers. It is also the strength most comparable to the 20mg disposable vapes sold in the UK, which are capped at that figure.

Some practical rules of thumb. If you smoke roughly ten cigarettes a day or fewer, start at the lower strength. If you smoke a pack a day and find the lower strength leaves you reaching for a cigarette, the higher strength is more likely to hold you. If you feel dizzy, nauseous, jittery or get a racing heartbeat, you have taken in more nicotine than your body wants; stop, drink some water and move to the lower strength or take fewer puffs.

Sour flavours add a wrinkle. Tart notes can sharpen the throat feel, so a 20mg bottle of Sour Green Apple may feel a touch more noticeable than a 20mg bottle of a sweet flavour at the same power. That is not a fault; it is how acidity and nicotine interact. If you are between strengths, lean lower and adjust upwards rather than the other way round. Many vapers eventually step down in strength as the habit settles, and that is entirely normal.

Devices, coils and mesh technology

IVG Nic Salt Sour Green Apple is designed for low-power devices, and the right match makes the difference between a tidy, flavourful vape and a flat or leaky one. The usual home for a 10ml salt bottle is a refillable pod kit. These come in two broad designs: closed pod systems that accept replaceable prefilled-style pods you top up, and open pod systems with a refillable tank-style pod and a replaceable coil.

Look for these characteristics in a suitable device:

• Coil resistance of about 0.8 to 1.2 ohm. This range is common for mouth-to-lung salt kits and gives a snug draw that suits tart flavours.
• Operating power of roughly 10 to 20 watts. Most salt kits run in this band, either at a fixed output or with a modest adjustment range.
• Pod capacity of about 2ml. This is the usual size for UK-sold refillable pods and is set by the same rules that cap tank size.
• Tight airflow. A restricted draw concentrates flavour and keeps the throat feel comfortable at salt strengths.

On coil construction, you will see two main types. Traditional wire coils sit inside a cotton wick and heat the liquid directly. Mesh coils use a flat or curved sheet of metal mesh with a large heating surface, and they are popular because they warm up quickly and spread heat evenly, which tends to give a fuller and more consistent flavour with fewer burnt hits. Either type can work with this liquid. Mesh coils tend to show the apple note more clearly, while wire coils sometimes feel a little softer on the sourness.

Do not use this liquid in a sub-ohm tank running at 40 watts or more. Salts are not designed for that and you will find the nicotine intake overwhelming, the liquid used up in no time and the tart flavour harsh. Do not pour salt liquid into a disposable device either; those are sealed, not designed to be opened, and doing so can damage the device or create a safety problem.

Battery, power and charging your pod kit

The battery belongs to your device rather than to the liquid, but it affects how Sour Green Apple behaves, so it is worth understanding. Refillable pod kits commonly ship with batteries somewhere between 400mAh and 1,000mAh. Those with a larger cell can sustain a full day of moderate use between charges, while the smallest slim kits may need topping up once during the day. Treat these as ranges rather than promises, because device power, puff length and coil resistance all change the draw on the battery.

Some practical guidance on power and charging.

• Match power to the coil. Run the device within the wattage range printed on the coil. Running above it burns the liquid, shortens coil life and turns a crisp apple into a scorched, bitter taste.
• Fixed-output kits. Many pod kits have no adjustable wattage and run at a preset level. That is fine for salts because the output is designed for them.
• Charging. Most current kits charge over USB-C. Expect roughly 30 to 90 minutes for a full charge depending on the battery size and the charger. Use the cable supplied or a reputable replacement.
• Charger choice. A standard 5V USB charger is enough. You do not need a fast charger, and a poor-quality one can overheat the cell.
• Where to charge. Charge on a hard, flat, non-flammable surface where you can see the device. Do not charge under pillows, on sofas or in bed, and do not leave a device charging overnight unattended.

Battery life also depends on how you vape. Long, slow draws at a higher output will drain a small cell faster than short pulls at a lower one. If your battery seems to be failing early, check that the connection between the pod and the battery is clean and dry, as a leak that creeps into the contacts can cause poor performance. When a battery is no longer holding charge, do not throw the device in the bin; the recycling section below explains how to dispose of it properly.

Throat hit, vapour and puff delivery

Because Sour Green Apple is a nicotine salt, you can expect a smoother throat feel than a freebase liquid of similar strength, but not a complete absence of throat hit. At 20mg/ml most people notice a definite but comfortable hit at the back of the throat, and at 10mg/ml it is lighter. The tart flavour contributes a bit to that sensation, which is why some vapers describe it as slightly zingier than the number on the bottle suggests.

Vapour production is moderate. Salt liquids are normally balanced between propylene glycol and vegetable glycerine so that they wick quickly in small coils. Check the label for the exact ratio, but a balanced blend is typical for the range. The result is a visible but modest cloud, nothing like the plumes produced by high-power setups, which is a benefit if you vape in places where discretion matters.

How puff delivery works with a refillable kit is different from a disposable, which is worth knowing if you are switching:

• A disposable has a puff count; a bottle has a volume. There is no fixed number of puffs from a 10ml bottle, because it depends on your device, power and habits.
• A rough guide. Many vapers using a small pod kit at 10 to 15 watts find a 10ml bottle lasts anywhere from one to three weeks. Heavy users go through it faster.
• Coil condition changes delivery. A fresh coil gives the strongest flavour; as it ages, the taste dulls and the vapour thins out. Swapping the coil restores both.

The upshot is that the vape feels the same from the first fill to the last, as long as the coil is healthy and the pod is kept topped up. If the vape begins to taste weak or burnt, it is almost always the coil rather than the liquid. That is a quick and cheap fix and is covered in the troubleshooting section.

Bottle design and build quality

The bottle is a small part of the product, but it is the part you handle every time you fill the pod, so it matters. A good nicotine e-liquid bottle in the UK has to meet certain requirements: it must be child-resistant, tamper-evident and, in the case of nicotine liquids, limited to 10ml. IVG Salt bottles follow that approach, with a plastic bottle and a narrow nozzle that lets you fill a pod without spilling.

What to check when your bottle arrives:

• Tamper-evident seal. The cap should have an intact ring or seal before first use. If it is broken or loose, contact the shop rather than using the liquid.
• Label information. The label should show the strength, flavour name, ingredients, batch number and the required health warning. Keep the label legible so you know what you are putting in your device.
• Child-resistant cap. Push-and-turn or similar caps are standard. Always close the cap fully after use.
• Nozzle fit. The thin tip is designed to fit the fill port of a typical pod. If your pod has an unusually narrow port, fill slowly and in short pulses.

Storage matters as much as the packaging. Keep the bottle upright, out of direct sunlight and away from heat, as light and warmth degrade the flavour and the nicotine over time. A cool drawer or cupboard is ideal. Store it out of reach of children and pets; nicotine liquid is poisonous if swallowed or if it gets on bare skin in quantity, and a bottle left on a table is an avoidable risk. If liquid gets on your skin, wash it off with soap and water. If it is swallowed or gets into the eyes, seek medical help immediately.

Unopened and stored properly, e-liquid usually keeps its quality for a year or more. Check the best-before date on the packaging, and avoid using liquid that has darkened noticeably or smells off.

How to fill and use Sour Green Apple

Filling a pod is straightforward once you have done it once or twice. Take your time the first time, because over-filling is the commonest cause of early leaks.

• Step 1: Prepare. Switch the device off or remove the pod. Wipe the pod and your hands so there is no dust or moisture around the fill port.
• Step 2: Open the port. Pull back the silicone plug or slide the cover aside, depending on the design.
• Step 3: Fill gently. Squeeze the bottle slowly and fill to just below the maximum line. Avoid the central chimney, which is the air channel running through the pod; liquid in the chimney floods the coil and causes gurgling and leaks.
• Step 4: Close up. Press the plug in fully and wipe away any spilled liquid with a tissue.
• Step 5: Let the coil soak. Wait five to ten minutes before the first puff. A dry coil burns instantly, and a burnt coil tastes harsh and cannot be rescued.
• Step 6: Prime. Take two or three gentle draws without pressing the fire button if your device allows it, then vape normally.

When using it day to day, take slow, even draws of two to four seconds. Mouth-to-lung means drawing the vapour into your mouth first and then inhaling it, much like drinking through a narrow straw. Do not take a deep, direct lung inhale on a salt pod kit; it is not designed for that, and it increases the nicotine hitting you at once.

A few habits extend the life of both coil and liquid. Keep the pod topped up so the wick never runs dry. Avoid chain-vaping long sequences of back-to-back puffs, which can outpace the wick and burn it. Change the coil when the flavour fades, usually every one to two weeks of regular use, though sour and sweet liquids can both shorten coil life through residue build-up. When switching flavours, rinse or replace the pod and coil so the apple is not muddied by leftover liquid.

Troubleshooting common problems

Most problems with salt liquids come down to the device, not the liquid. Here are the usual ones and what to do about them.

• Burnt or bitter taste. Almost always a dry or worn-out coil. Replace the coil, let it soak properly and avoid chain-vaping. If a fresh coil burns, check you have not overfilled the chimney or set the power above the coil's range.
• Weak flavour. The coil may be tired, the pod may be low on liquid, or your tongue may be fatigued by the flavour. Try a fresh coil and a different flavour for a day to reset your palate.
• Leaking. Causes include overfilling, a worn silicone seal, a cracked pod or pressure changes from travel. Fill to below the maximum line, check the seal, and carry the device upright.
• Gurgling. Liquid has reached the airflow channel. Remove the pod and blow gently through the mouthpiece, or wipe the chimney with a tissue.
• Throat feels too harsh. You may be on too high a strength, drawing too hard or running too much power. Try a lower strength, slower draws or a lower wattage.
• Device will not fire. Check the pod is seated properly, the contacts are clean and dry, and the battery has charge. Wipe the contacts with a dry cloth.
• Sour taste is too sharp. Lower the power slightly, take shorter draws and make sure you are not on a cold, dry coil. If it remains too tart, a sweeter fruit flavour may suit you better.
• Dizziness or nausea. Stop vaping, sit down and drink water. Drop to a lower strength next time or take fewer puffs.

If a problem persists after you have checked the device and the coil, contact the shop with your order number and a description of what happens. Do not try to open or repair a battery yourself, and stop using any device that gets unusually hot, swells or smells of burning.

Who Sour Green Apple is for, and who should look elsewhere

Being clear about who a product suits is more useful than a blanket recommendation. Here is an honest breakdown.

Sour Green Apple is likely to suit:

• Adult smokers moving to vaping. The salt format is the one most commonly chosen by people stepping away from cigarettes, and the 20mg strength is the usual starting point for daily smokers.
• Disposable users wanting a refillable device. If you currently use a 20mg disposable and like fruit flavours, a pod kit with this liquid gives a similar experience with less waste.
• Fans of tart and fruity flavours. If you reach for sour sweets, green apple or citrus-led vapes, this is aimed squarely at you.
• Vapers who find sweet liquids tiring. The tang keeps the flavour lively across a long day.

It is probably not the right choice for:

• Non-smokers and under-18s. Nicotine is addictive, and vaping is not for people who do not already use nicotine. It is illegal to sell to anyone under 18.
• Anyone who is pregnant or breastfeeding, or who has a heart condition, without medical advice.
• Fans of dessert or menthol flavours. If you want cream, custard or an icy blast, other flavours in the range will suit you better.
• High-power sub-ohm users. This is a salt liquid for low-power devices.
• Anyone with a sensitive throat or acid reflux. Tart flavours can sometimes aggravate these. If sour flavours bother you, choose a smoother fruit instead.

A final word on the purpose of vaping. For adult smokers, switching fully from cigarettes is a well-supported way to reduce exposure to the harmful substances in smoke, according to UK public health bodies. It is not risk free, and the aim is to move away from smoking, not to add vaping on top of it. If you want support to quit, the NHS Stop Smoking service can help.

Value for money and how it compares

Cost is where refillable vaping usually wins. A 10ml bottle of salt liquid costs a few pounds, and the cost per millilitre is generally lower than the equivalent from a disposable. A typical disposable holds 2ml of liquid, so a 10ml bottle contains five times as much, for a price that is often less than two disposables. Over a month the saving can be substantial, though you also need to account for the upfront cost of a pod kit and the periodic cost of replacement coils.

Here is how it stacks up against the alternatives:

• Against disposables. Disposables are convenient, with no filling or coil changes, but they cost more per millilitre, generate more waste and are limited to the 2ml, 20mg format. A refillable setup asks a little more of you in return for lower running costs and a wider choice of flavours and strengths.
• Against other salt ranges. Plenty of brands sell 10ml salts at similar prices. IVG is a well-known UK name with a broad flavour list, so you are unlikely to run out of variants to try. Some competing ranges offer a wider choice of strengths such as 5mg or 18mg, and some offer 50/50 versus higher-VG blends. If you need a specific strength that is not listed here, another brand may fit better.
• Against freebase liquids. Freebase in larger 50ml or 100ml bottles with nicotine shots is cheaper per millilitre again, but it needs a sub-ohm tank and more mixing. Salts trade a little of that saving for convenience and a smaller device.

The honest caveat is that a sour flavour is a matter of taste. If you find tart fruit unpleasant, no price advantage will make up for that, so consider a smaller first purchase if you are unsure. If you do enjoy it, buying several bottles at once can reduce the per-bottle cost and delivery charge.

When you have finished with a bottle, recycle it. Empty plastic bottles can go with household plastic recycling where local rules allow, or be taken to a retailer drop-off point. Used pods, coils and batteries should never go in the bin; they belong in a dedicated electrical or battery recycling point, and many UK vape shops and supermarkets provide them.
