Overview of Yeti Original 100ml Sour Grape

Yeti Original 100ml Sour Grape is a shortfill e-liquid from Yeti, a UK e-liquid brand with a broad range of fruit, sweet and chilled flavours sold in large bottles for sub-ohm vaping. This flavour pairs a ripe, juicy grape base with a sharp, tart sour finish. It is supplied as 100ml of nicotine-free liquid in a 120ml bottle, which leaves space for you to add nicotine shots and reach a strength that suits you.

Shortfills exist because UK rules cap bottles of nicotine-containing e-liquid at 10ml and cap the nicotine strength at 20mg/ml. By selling the flavoured liquid at 0mg in a larger bottle and supplying nicotine shots separately, retailers let you buy a bigger volume at a lower cost per ml. If you have only used ready-mixed 10ml bottles before, the 100ml format is a change in routine, because you decide the final strength yourself.

The base is high-VG. Yeti's Original shortfill range is generally listed at around 70VG/30PG, but you should always check the label on the bottle you receive, because brands can adjust recipes between batches. A high-VG liquid is thicker and produces denser vapour. It is intended for sub-ohm tanks and higher-wattage devices rather than small, tight-draw pod systems.

Here are the quick facts at a glance.

• Product: Yeti Original 100ml Sour Grape shortfill e-liquid
• Flavour: grape with a sour, tart finish
• Volume: 100ml of liquid in a 120ml bottle, with room for up to two 10ml nicotine shots
• Nicotine as supplied: 0mg/ml
• Typical base ratio: around 70VG/30PG (confirm on the label)
• Suited to: sub-ohm tanks and devices running mesh coils
• Age restriction: 18+ only, UK sales

This guide is written to be straight about what the liquid does well and where it may not suit you. It covers flavour, vapour delivery, bottle design, the equipment you will need to run it, nicotine strength, mixing, troubleshooting, value and the safety and recycling points that matter in the UK.

Flavour profile: grape with a sour edge

The inhale leads with grape. Expect something closer to the taste of purple grape juice or a grape sweet than to a wine grape, with a rounded, fruity sweetness that arrives first. Within a second or so, the sour element comes through as a tart tang along the sides of the tongue, similar to the sharpness of a sour sweet coating. It is there to cut through the sweetness rather than to dominate it.

On the exhale the grape lingers and the sour note fades, leaving a gently sweet finish. Because the base is high-VG, the flavour feels smooth and slightly rounded, and the vapour has a soft, creamy texture compared with a higher-PG liquid. At 0mg there is very little throat hit, so the flavour does most of the work.

Sweetness sits in the medium-to-high range, which is typical for fruit shortfills of this type. If you prefer drier, less sugary liquids you may find it on the sweeter side. If you enjoy candy-style fruit flavours, the balance should feel familiar.

A few things change how the flavour comes across:

• Wattage: lower power tends to mellow the sour edge and bring out the sweeter grape, while higher power makes the tartness sharper and the vapour warmer.
• Nicotine: adding a nicotine shot introduces a slight peppery note and a little throat hit, which can make the sour edge feel more pronounced.
• Coil condition: a fresh mesh coil gives the clearest flavour. As the coil ages, the grape tends to flatten and the sweetness can turn slightly muddy.
• Airflow: a tighter airflow concentrates flavour, while a wide-open draw gives more vapour and a lighter taste.

One honest caution: sour flavours can be tiring on the mouth. Some vapers find that vaping a sour liquid all day leaves the tongue feeling sensitive or slightly sore, and the sense of taste can dull over time, which people often call vaper's tongue. If that happens, take a break, drink water, and consider alternating with a milder fruit or menthol flavour. Taste is personal, so treat these notes as a guide rather than a guarantee.

Performance and puff delivery

E-liquid does not have a puff count in the way a disposable does, because how long it lasts depends on your device, power setting and habits. It is still useful to put a number on it. As a rough estimate, a sub-ohm setup at 40 to 70W uses somewhere between 0.02ml and 0.06ml of liquid per puff, which means a 100ml bottle could deliver roughly 2,000 to 4,000 puffs. Treat that as a ballpark, not a promise.

To make that more practical, here is how it tends to translate into days of use:

• Light user (around 2 to 3ml a day): a bottle can last four to five weeks.
• Average sub-ohm user (around 4 to 6ml a day): roughly two to three weeks.
• Heavy user (8ml or more a day): around ten to twelve days.

For comparison, a single-use disposable sold under UK rules held 2ml of e-liquid and was capped at 20mg/ml nicotine, usually advertised at around 600 puffs. A 100ml bottle holds fifty times the liquid of one of those, which is one reason many former disposable users moved to refillable kits. Single-use disposable vapes have also been prohibited from sale in the UK since 1 June 2025, so refillable devices and bottled liquids are the main route for people who want a fruit flavour like this one.

Vapour production is where a 70VG liquid stands out. Expect dense, thick clouds from a sub-ohm tank, with a smooth draw and very little harshness at low nicotine levels. Throat hit is mild at 0mg and still gentle at 3mg. If you want a noticeable throat hit, this is not the right format, and you should look at the nicotine strength section below.

Flavour delivery is consistent from a well-primed mesh coil. The first few puffs after refilling can taste slightly flatter while the cotton re-saturates, and that is normal rather than a fault. Performance depends heavily on matching the liquid to the right coil and power, which is covered in the coil section.

Bottle design and build quality

The liquid comes in a 120ml bottle, which is larger than the 100ml of liquid inside so that you can add nicotine shots without decanting anything. Shortfill bottles of this type are usually soft, squeezable plastic with a narrow nozzle for filling tanks neatly, and a tamper-evident, child-resistant cap. Always check what arrives in your parcel, because packaging details can be updated.

The label should carry the brand and flavour name, the 100ml volume, ingredients, batch number, best-before date, a nicotine-free statement, and the usual warnings. UK rules also expect child-resistant and tamper-evident closures on e-liquid containers, so an unsealed bottle is a reason to contact the seller rather than use it.

These are the practical things worth noting about the bottle:

• Squeezable body: makes it easy to control the flow when filling a tank, though you should squeeze gently to avoid a sudden gush.
• Narrow nozzle: fits most standard tank fill ports. If your fill port is very small, check that the tip reaches it before you open the bottle over the tank.
• Headroom: the 20ml of empty space is for nicotine shots. If you plan to leave it at 0mg you can use the extra space to shake the bottle more easily.
• Closure: the child-resistant cap needs a firm push and turn. That is intentional and worth keeping that way, especially in homes with children or pets.

The weight and size make the bottle easy to keep at home but less convenient for carrying all day. Most people decant a small amount into a smaller refill bottle for travel. If you do that, label it clearly and keep it away from children.

In terms of build, the main thing to look for is a tight cap seal and a clean, readable label. Plastic shortfill bottles are light and unbreakable in normal use, which is practical, but they should be stored upright so that residual liquid does not collect around the cap and leave sticky marks.

Devices, batteries and charging

The liquid itself has no battery, so battery performance comes down to the device you pair it with. Because Yeti Original Sour Grape is a high-VG liquid, it works best in sub-ohm tanks and mods or kits that can run between roughly 40W and 80W. That affects which batteries and chargers matter.

Here is a practical guide to what you will see on the equipment side:

• Built-in battery kits: typically 1,500 to 3,000mAh. At 40 to 60W you can expect a day of moderate use from a mid-sized kit, but power use climbs quickly as wattage increases.
• Removable 18650 cells: generally 2,500 to 3,500mAh. Dual-cell mods double the capacity and often suit heavier use.
• 21700 cells: generally 4,000 to 5,000mAh, offering longer runtime for single-cell devices.

Charging habits matter more than most people expect. Use the charger and cable that came with your device, or a dedicated external charger for loose cells. Do not charge batteries under a pillow, on soft furnishings or unattended overnight. Never carry loose cells in a pocket with keys or coins, and use a case. If a battery wrap is torn or the cell is dented, stop using it and replace it.

Sub-ohm vaping draws a lot of current, so match your coil resistance and wattage to the battery's rating. If you are new to removable-battery devices, use a device with built-in safety protections and follow the manufacturer's guidance rather than guessing at settings.

When batteries or devices reach the end of their life, do not put them in household bins or normal recycling. Lithium cells can start fires in bin lorries and waste sites. Take them to a household waste recycling centre, use the in-store battery or electrical take-back points offered by many retailers, or find your nearest drop-off point with the Recycle Your Electricals locator. This applies to old vape kits, mods and any single-use devices you may still have at home.

Coil and mesh compatibility

A 70VG liquid is thick, so the coil and wick need to be able to draw it in quickly. That is why shortfills like this are normally used with sub-ohm mesh coils. A mesh coil has a wide, flat surface area that heats evenly and absorbs liquid fast, which suits both the vapour density and the flavour.

These are sensible starting points, though you should always follow the range printed on the coil you buy:

• 0.15 to 0.3 ohm mesh coils: often rated for roughly 50 to 90W. These produce large clouds and a warm vape, and they use liquid quickly.
• 0.4 to 0.6 ohm mesh coils: often rated for roughly 25 to 50W. They give a more restrained, flavour-focused vape and are easier on battery and liquid.
• Standard round-wire sub-ohm coils: work with thick liquid but tend to give less even flavour than mesh.
• Ceramic or tight MTL coils above roughly 0.8 ohm: usually do not wick thick liquid well, and are more likely to give dry hits.

Pod kits deserve a specific mention. Some pod systems with 0.6 ohm mesh coils cope with higher-VG liquids reasonably well, but many are designed around 50/50 or nicotine salt liquids, and a 70VG shortfill can wick slowly in them. Check the manufacturer's recommended VG range for the pod before buying.

Priming is the step that decides how long a coil lasts. Before the first puff, drip a few drops of liquid directly onto the exposed cotton, fill the tank, and let it rest for five to ten minutes. Start at the lowest wattage in the coil's range and increase gradually. Chain vaping at high power with an under-primed coil is the quickest route to a burnt taste.

Fruit and sweet liquids with sweeteners tend to build residue on a coil. Depending on use, expect a coil to last around one to two weeks. If the flavour starts to dull or you notice a slight burnt edge, change the coil rather than turning up the power.

Nicotine strength guidance

As supplied, this liquid is 0mg/ml. You can vape it nicotine-free, or add nicotine shots to reach a low strength. The 120ml bottle is sized for this: 100ml of liquid plus up to 20ml of nicotine shots.

Using standard 18mg/ml shots, the arithmetic works out as follows:

• No shots: 0mg/ml.
• One 10ml shot (110ml total): approximately 1.6mg/ml.
• Two 10ml shots (120ml total): 3mg/ml.

That is the practical ceiling for this format. If you need more than around 3mg/ml, a 100ml shortfill is not the most suitable product, and a nicotine salt or higher-strength freebase 10ml bottle would suit you better. Nicotine shots themselves are capped at 20mg/ml in UK rules, the same ceiling that applied to disposable vapes, so a stronger final mix is not available in this bottle.

As a general guide, and not as medical advice:

• 0mg: for people who vape purely for flavour, or who have already come off nicotine.
• Around 1.6mg: light users, occasional vapers or those cutting down.
• 3mg: a sensible starting point for sub-ohm users who previously smoked a moderate amount, though heavier former smokers may find it too light.

Nicotine salts, which are often sold at 10mg/ml or 20mg/ml, are designed for lower-power devices and tight draws. They are not meant for sub-ohm tanks at high wattage, where the dose delivered per puff becomes very high. Do not try to mix nicotine salt shots into a sub-ohm setup to chase a stronger hit.

Nicotine is addictive. This product is intended for adults who already smoke or vape. If you do not use nicotine, there is no health reason to start, and the 0mg version of this liquid is the one to stay with. If you are pregnant, have a heart condition or take regular medication, speak to a pharmacist or your GP before using nicotine products.

Who Yeti Original Sour Grape is for

This liquid is aimed at adult vapers who already use a sub-ohm tank or a high-VG-friendly kit and who enjoy fruit flavours with a sharper edge. It will make most sense if you fit one or more of the groups below.

• Sub-ohm users: if you already run a mesh coil at 40W or above, this liquid is made for that style of vaping.
• Fruit and sour fans: grape is a familiar flavour, and the sour note adds some contrast for people who find plain fruit liquids too sweet.
• Cost-conscious vapers: 100ml bottles generally work out cheaper per ml than 10ml bottles, which matters if you vape several millilitres a day.
• Low-nicotine or nicotine-free users: the 0mg to 3mg range fits people who want flavour first.
• Former disposable users: if you were using single-use fruit vapes before the ban, a refillable kit with a flavour like this is a more economical and less wasteful alternative.

It is probably not the right choice in the following situations:

• You want a strong throat hit or higher nicotine: a 100ml shortfill tops out around 3mg/ml, so nicotine salt or a 10ml freebase bottle will suit you better.
• You use a tight MTL pod or a small pen-style device: 70VG liquid is thick for these and may cause poor wicking, gurgling or dry hits.
• You dislike sour or acidic flavours: some people find them harsh, especially over a full day of vaping.
• You are new to mixing nicotine shots: it is manageable, but if you want something pre-mixed, a 10ml nicotine-containing bottle is simpler.
• You are under 18 or a non-smoker: vaping products are for adult smokers and existing vapers only.

If you are undecided between flavours, remember that you commit to a full 100ml of one profile. If you like variety, ordering a smaller bottle first, or choosing a few 10ml options, can reduce the risk of tiring of a single taste.

How to mix, fill and use it

Using a shortfill is straightforward once you have done it a couple of times. Work in a clean, well-lit space, away from children and pets, and wipe up any spills straight away, because nicotine liquid can irritate skin.

• Step 1, decide your strength: choose whether to stay at 0mg, or add one or two 10ml nicotine shots as outlined in the nicotine section.
• Step 2, add the shots: open the shortfill bottle, add the shots carefully, and refit the cap firmly. Do not overfill beyond the bottle's marked limit.
• Step 3, shake: shake the sealed bottle for around 30 to 60 seconds, then rest it for a few hours if you can. High-VG liquids can take a little time to blend fully.
• Step 4, fill the tank: tilt the tank, fill along the side of the glass, and avoid the central airflow tube. Leave a small air gap at the top, and close the fill port.
• Step 5, prime the coil: let the liquid soak into the cotton for five to ten minutes before the first puff.
• Step 6, start low: begin at the lower end of the coil's wattage range, take gentle three-second puffs, and pause for 20 to 30 seconds between them.

A few habits help the liquid perform well. Keep the tank at least a third full, because running it low is a common cause of dry hits. Wipe the mouthpiece and the bottle nozzle after use. Refit the child-resistant cap straight after each fill. If you are decanting into a smaller bottle, label it with the flavour, strength and date.

Steeping is optional with fruit liquids, but a day of rest sometimes helps when nicotine has been added, as the flavour can taste slightly sharper immediately after mixing. Keep the bottle in a cool, dark place while it rests.

Remember that vaping products are legal only for adults aged 18 and over in the UK, and a courier may ask for ID on delivery.

Troubleshooting common problems

Most issues with shortfills come from a small set of causes. Work through the likely ones below before assuming the liquid is faulty.

• Burnt or dry taste: usually an under-primed or worn coil, a low liquid level, or too much power for the coil. Refill, prime for several minutes, drop the wattage and replace the coil if it persists.
• Weak or flat flavour: often an ageing coil or a very airy draw. Try a fresh coil, slightly tighter airflow and a modest rise in power.
• Gurgling or spitting: a sign of too much liquid or condensation around the coil. Clean the tank, dry the airflow channels, and avoid over-filling.
• Leaking tank: check the O-rings, make sure the coil is screwed in fully, and avoid squeezing the tank. Store the device upright.
• Hard draw: thick liquid in a tight system can restrict airflow. Open up the airflow or use a coil intended for higher-VG liquids.
• Sour note feels harsh: lower the wattage, avoid chain vaping, and consider mixing with a milder liquid of your own at a smaller ratio.
• Sore tongue or mouth: a known side effect of some sour flavourings. Take a break, hydrate, and switch to a gentler flavour for a day or two.
• Sticky bottle or cap: wipe the neck clean after filling. High-VG liquid leaves a film that attracts dust.
• Cloudy appearance or separation: shake the bottle. If the liquid smells off or looks very different from normal, stop using it and contact the seller.

If you have tried a new coil and correct priming and the problem remains, contact customer support with your order number, the batch number on the bottle and a short description of the device and settings you used. That gives the best chance of a quick resolution.

For any symptoms such as persistent coughing, chest tightness or dizziness, stop vaping and seek medical advice. Do not assume that a flavour or device issue is the cause.

Value for money and how it compares

The main argument for a 100ml shortfill is cost per millilitre. Ten-millilitre nicotine-salt bottles and prefilled pods cost noticeably more per ml, and a single-use vape of the past delivered only 2ml of liquid. If you vape a few millilitres a day, buying liquid in 100ml bottles is generally the more economical route. Check the current price shown on this page rather than relying on a figure written here, since prices change.

Value also depends on what you need to add. Nicotine shots are an extra cost, so if you plan to run 3mg you should budget for two shots per bottle. Coils are a running cost too, and a worn coil can make any liquid taste poor.

Here is a fair look at the alternatives:

• Other 70VG fruit shortfills: brands such as IVG, Doozy Vape Co and Pukka Juice sell comparable 100ml bottles, and prices are broadly in a similar band. The real differences are flavour recipes and personal preference, so we would not claim that one tastes better than another. Some competitor ranges have more menthol-heavy or dessert-focused options, while Yeti's Original range leans toward fruit and sweet profiles.
• 10ml nicotine-salt bottles: convenient, pre-mixed and suitable for pod kits and tight draws, but more expensive per ml and limited to low-power devices.
• Prefilled pods: simple and tidy, but you are tied to a specific device and flavour range, with higher running costs.
• Other flavours within Yeti Original: if grape with a sour edge is not appealing, the same brand offers a range of other fruit and sweet options in 100ml bottles at comparable pricing.

Where the sour grape flavour may fall short is in strength flexibility, because it tops out around 3mg, and in variety, because 100ml of one sour flavour can feel repetitive for some people. If you value choice, rotating a couple of flavours is a sensible approach.

Overall, for a sub-ohm user who enjoys fruit with a sour twist, it offers a reasonable cost per ml and a familiar flavour. For pod users, high-nicotine users or people who dislike sour tastes, a different product will serve you better.

Storage, safety, UK rules and recycling

Store the bottle upright in a cool, dark place, away from direct sunlight, radiators and car dashboards. Heat and light can degrade e-liquid, change the colour and flatten the flavour. Always check the best-before date printed on the label, and do not use liquid that smells unusual or looks very different from when it arrived.

Keep every bottle, and especially nicotine shots, out of the reach of children and pets. Nicotine is toxic if swallowed, and a mixed bottle is no less hazardous than a shot. If liquid gets on your skin, wash it off with soap and water. If it gets in your eyes, rinse with water and seek medical help. If someone swallows e-liquid, call NHS 111 or 999 immediately, and have the bottle with you.

A few UK rules are relevant to anyone buying this product:

• Age: vaping products can only be sold to people aged 18 or over, and retailers and couriers may check ID.
• Nicotine strength: nicotine-containing e-liquid is capped at 20mg/ml, and bottles of nicotine liquid are limited to 10ml. That is why shortfills are sold at 0mg with shots supplied separately.
• Tank size: refillable tanks are limited to 2ml capacity under UK rules, so check your device is a UK-market model.
• Product notification: products sold in the UK must be notified to the MHRA before sale. If you are unsure about a seller, ask for evidence.
• Disposables: single-use vapes have been banned from sale since 1 June 2025.

On disposal, an empty plastic e-liquid bottle can often go in household plastic recycling, but councils differ, so check your local guidance and remove the nozzle and cap if asked. Do not pour unused nicotine liquid down the drain; follow your council's advice for hazardous household waste. Old vape devices, chargers and batteries belong in electrical or battery recycling, and you can find drop-off points through the Recycle Your Electricals locator, your local household waste recycling centre or the take-back points offered by many retailers.
