Overview: what Zeus Bolt Nic Salts Cola Ice is

Zeus Bolt Nic Salts 10ml 20mg Cola Ice is a nicotine salt e-liquid sold in a 10ml bottle. It is made for refillable pod kits and other low-powered mouth-to-lung devices, and it pairs a fizzy cola flavour with a cooling ice finish. The strength is 20mg/ml, which is the highest nicotine level the UK allows in any e-liquid, so this bottle sits at the firm end of the range and is aimed at adult smokers who want a satisfying hit from a small, discreet device.

It helps to be clear about what this product is and is not. It is a liquid, not a vape. There is no battery, no coil and no charger in the box, and it will not do anything until you pour it into a compatible refillable pod or tank. If you are used to disposables, this is the refillable route, and it has become more relevant in the UK since single-use vapes were banned from sale on 1 June 2025. A 10ml bottle of nic salt will fill a typical 2ml pod several times over, which is where the running-cost advantage comes from.

Here are the headline facts at a glance:

• Brand: Zeus, Bolt nic salt range
• Type: nicotine salt e-liquid, not a shortfill and not a freebase liquid
• Bottle size: 10ml, the UK maximum for any bottle of nicotine-containing e-liquid
• Nicotine strength: 20mg/ml (2%), the UK legal ceiling
• Total nicotine in the bottle: 200mg (10ml multiplied by 20mg/ml)
• Flavour: Cola Ice, a fizzy cola profile with a cooling finish
• Suited to: pod systems, refillable pod kits and low-wattage mouth-to-lung devices
• Not suited to: high-wattage sub-ohm tanks, which are built for lower-strength liquids

Nicotine salts differ from traditional freebase nicotine in how the nicotine is bound with an acid, which makes the vapour noticeably smoother at higher strengths. That smoothness is the reason 20mg salts are popular with people switching from cigarettes: you get a quick nicotine response without the harsh throat scratch that 20mg freebase would produce. Where the exact blend of VG and PG matters to you, check the label on the bottle in your hand, because ratios can differ between ranges and batches.

The rest of this guide covers performance, flavour, the hardware that suits it, strength guidance, practical use, troubleshooting, value, and an honest look at how it compares with other 10ml nic salt options on the UK market. It is written for adults who already smoke or vape. If you do not use nicotine today, this is not a product to start with.

Performance and puff delivery

Because this is an e-liquid rather than a finished device, performance depends on the hardware you put it in. That said, nic salts in 10ml bottles are formulated for a fairly narrow set of devices, so you can set realistic expectations. In a pod kit running somewhere between 8W and 15W with a coil of roughly 0.6 to 1.2 ohms, Zeus Bolt Cola Ice should deliver a compact, dense vapour with a firm but rounded throat hit and a fast nicotine response.

Puff count is the question most people ask, so here is a practical estimate rather than a marketing number. Mouth-to-lung puffs on a pod device typically use somewhere between 0.003ml and 0.01ml of liquid each, depending on wattage, puff length and coil. Across a full 10ml bottle that works out at roughly 1,000 to 3,000 puffs. Treat that as a range, not a promise. A light user taking short, gentle draws at low power will sit at the top end, while someone running a higher wattage and taking long pulls will get through it faster.

As a rule of thumb for planning, this is how a bottle tends to last:

• Light use, around 1ml a day: a bottle lasts roughly ten days.
• Moderate use, around 2ml a day: roughly five days.
• Heavy use, 3ml or more a day: roughly three days, though at 20mg/ml that is a lot of nicotine and worth reviewing (see the strength section below).

Vapour volume is modest by design. Nic salt liquids are usually built around a balanced VG and PG blend, which produces a tighter cloud than the thick high-VG liquids used in sub-ohm tanks. If you like large clouds, this is the wrong format. If you want something close to the feel of a cigarette, with a tight draw, a controlled amount of vapour and a quick hit, it is the right one.

Throat hit at 20mg in a salt formulation is noticeable but smooth. Expect a gentle tickle at the back of the throat on the first few puffs, which settles as you adjust. The cooling element in Cola Ice adds a crisper edge to the inhale, which some vapers read as a stronger hit than the same strength in a plain flavour. If it feels too sharp, lower the wattage a notch before you reach for a lower-strength bottle.

Consistency across a bottle is generally good with nic salts because the nicotine is stable and the liquids are thin enough to wick reliably. Flavour intensity tends to be highest in the first few pods after opening, and it softens a little over weeks as the bottle is exposed to light and air, which is why correct storage matters (covered in the bottle and build section).

Flavour profile: cola with a cooling finish

Cola Ice is a straightforward concept: the familiar sweet, caramelised, slightly spiced taste of a fizzy cola drink, finished with a cooling layer that sits on the exhale. Flavour is subjective and everyone's palate reads these liquids a little differently, but liquids in this style tend to follow a consistent pattern, and that is the pattern to expect here.

On the inhale, cola flavours usually lead with a rounded caramel sweetness and a hint of citrus, often lime or orange peel, which gives the drink its recognisable bite. Underneath that sits a soft vanilla and spice note that makes it taste like cola rather than a generic sweet. The fizz is suggested rather than literal. You will not get bubbles, but the sharper citrus edge and the cooling agent together create an impression of carbonation that works well in vapour form.

On the exhale, the ice element takes over. This is a cooling sensation rather than a heavy menthol blast. It lingers briefly on the tongue and the roof of the mouth, and it lifts the sweetness so the flavour does not feel cloying. If you find full menthol liquids too medicinal, a cooling finish like this is usually easier to live with, although anyone who dislikes any cooling effect should look at the non-iced version of a cola flavour instead.

• Inhale: caramel-sweet cola with a citrus and spice edge
• Exhale: light to moderate cooling that fades quickly
• Sweetness: medium to high, as is typical for dessert and soda flavours
• Aftertaste: clean, with a faint sweet cola note

Sweetness is the one thing worth flagging honestly. Soda profiles rely on sweeteners to taste right, and sweeteners are the main cause of coil gunk. If you vape a sweet liquid all day, you will change coils more often than you would with a tobacco or plain menthol flavour. That is a trade-off rather than a flaw, but it is a real cost and we cover it in the coil section.

Flavour fatigue is also worth mentioning. Some vapers love a single flavour for months, while others notice that sweet profiles lose their appeal after a couple of weeks. If you tend to get bored, buying a second bottle in a different profile and rotating between them keeps things fresh. The strength and bottle size are identical across the range, so swapping is simple.

Temperature changes the taste. At lower wattage the cola and citrus notes come through more clearly, with a gentler cooling. Turn the power up and the sweetness deepens, the cooling gets stronger and the vapour runs warmer. Start low and move up in small steps until it tastes the way you want.

Bottle design, labelling and build quality

With an e-liquid, build quality means the bottle, the cap, the labelling and the packaging, because those are the parts that affect safety and day-to-day use. A 10ml bottle of nicotine e-liquid sold in the UK has to meet specific packaging rules, and you can use them as a checklist when your order arrives.

• Child-resistant cap: the lid needs a push-and-turn or similar mechanism. If it opens with no resistance at all, contact the retailer.
• Tamper-evident seal: a ring or seal that breaks on first opening. A bottle that arrives already open should not be used.
• Nozzle: a narrow tip designed for filling small pod ports without spilling. Check it is firmly seated before you squeeze.
• Label information: a nicotine health warning, ingredients list, nicotine strength, batch number and supplier details.
• Bottle volume: no more than 10ml, which is the legal maximum for nicotine-containing liquid.

The bottle is typically a soft plastic design, which makes controlled filling easier than a rigid one. Squeeze slowly and keep the nozzle pressed against the edge of the fill port to avoid air bubbles and overflow. If a bottle has been jostled in transit and a little liquid has crept around the neck, wipe it clean before use and wash your hands afterwards, because nicotine is absorbed through skin.

Storage affects both safety and flavour. Keep the bottle upright, closed and out of direct sunlight, away from heat sources such as radiators and car dashboards, and well out of reach of children and pets. Nicotine liquid is poisonous if swallowed and can be harmful on skin contact. If the liquid does get on your skin, wash it off with soap and water. If it is swallowed or gets in the eyes, seek medical advice straight away and take the bottle with you.

Shelf life is usually printed on the label as an expiry date, commonly 12 to 24 months for sealed nic salts. A liquid that has darkened slightly is not necessarily spoiled, because nicotine oxidises over time and tends to deepen in colour, but if the smell or taste has changed noticeably, it is better to replace it.

At the end of the bottle's life, take care over disposal. Empty bottles still contain nicotine residue, so do not pour leftover liquid down the sink and do not leave bottles where children can reach them. Many councils accept clean empty plastic bottles in household recycling, but local rules vary, so check your council's guidance before you put them in the kerbside bin. Cardboard outer packaging can go in normal paper and card recycling.

Battery and charging: what your device needs

The liquid itself has no battery, so this section is about the device you will pair it with. Getting the hardware right matters more with a 20mg nic salt than with most liquids, because the strength is high and the formulation is designed for modest power.

Most pod kits that suit nic salts carry a built-in battery somewhere between 400mAh and 1,000mAh, and those that take replaceable cells use standard 18650 or 21700 batteries in more powerful mods. For the 8W to 15W range this liquid is built for, the demand on the battery is gentle. As a rough guide, a 800mAh to 1,000mAh pod kit usually gives a full day of moderate use between charges, while a 400mAh to 500mAh pen-style pod will need topping up once or twice a day.

• Charging port: USB-C is now standard on current pod kits and is faster and less fiddly than older micro-USB.
• Charger: use a standard 5V phone-style charger or a computer USB port. Fast chargers with higher output are not needed and add no benefit.
• Charging time: most pod kits take 45 minutes to 90 minutes to fill from empty.
• Pass-through: many devices let you vape while charging, but it is better to charge, then vape, to protect the cell and avoid heat build-up.

Safe charging habits are worth following with every lithium-ion device. Charge on a hard, non-flammable surface rather than a bed or sofa, do not leave a device charging unattended overnight, and stop using any battery that has swollen, is leaking or is visibly damaged. Do not carry a loose vape in a pocket with coins or keys, because contact with metal can short the terminals.

When a device reaches the end of its life, do not put it in the household bin or the kerbside recycling. Lithium batteries cause fires in refuse lorries and recycling plants. In the UK, shops that sell vapes are required to take back waste vapes and batteries, so you can drop an old device at a participating retailer, and most household waste recycling centres also have a small electrical items or WEEE point that accepts them. Check that the battery stays inside the device, and place it in the collection container rather than leaving it loose.

If you are shopping for a first device to use with this liquid, look for a kit that accepts nic salt specifically, lists a coil resistance of 0.8 ohm or above for the lower-wattage options, and has adjustable airflow so you can tighten the draw. Auto-draw pods with no buttons are fine, while adjustable-wattage devices give more control over throat hit and flavour intensity.

Coil and mesh technology: matching liquid to hardware

The coil is where the liquid becomes vapour, and the right coil makes the difference between a smooth, flavourful puff and a harsh or burnt one. Nic salts like Zeus Bolt Cola Ice are designed for coils that heat the liquid gently, so the sweet, cooling flavour comes through without scorching.

There are three coil types you will meet in pods that suit 20mg salts:

• Standard wire coils: traditional Kanthal or stainless steel wire wrapped around cotton. Typical resistance for mouth-to-lung use is 0.8 to 1.2 ohms. They are inexpensive and warm up quickly, but heat is concentrated in a small area, so flavour is usually a little less even than on mesh.
• Mesh coils: a flat sheet of mesh wrapping the wick, which spreads heat across a larger surface. For restricted draws on a pod, 0.6 to 0.8 ohm mesh coils are common. Flavour tends to be more consistent and the coil lasts a little longer, although it is generally priced higher.
• Ceramic coils: a porous ceramic core with the heating element embedded. These are known for clean flavour and long life with thinner liquids but can be less forgiving of very sweet or sticky e-liquids.

Resistance and wattage work together. A 1.0 ohm coil at 10W to 12W is a sensible starting point for a 20mg salt. A 0.6 ohm mesh coil will want a little more power, around 12W to 15W, to reach its optimum. Always check the coil's printed wattage range and stay inside it. Pushing a coil above its range burns the wick, ruins flavour and shortens life.

Wicking and priming deserve a line of their own, because most coil problems start there. A fresh coil needs time to soak. After you fill the pod, wait five to ten minutes before you take the first puff so the cotton is saturated, then take a few gentle low-power puffs. Skipping this step is the quickest way to a dry hit and a burnt coil on day one.

Coil life depends on liquid, power and puffing pattern. With sweet cola liquids, expect to change a coil every one to two weeks of regular use. Signs it is time include a dull or slightly burnt taste, reduced flavour, a gurgling noise, or increased throat harshness at your usual settings. Changing the coil when it first fades is cheaper than persevering with a tired one and wasting liquid on poor flavour.

One firm limit: do not use this liquid in a sub-ohm tank at high wattage. At 40W or more, a 20mg salt delivers far more nicotine per puff than most people want, tastes harsh and burns through the bottle quickly. Salts belong in pod-style hardware.

Nic strength guidance and the UK 20mg cap

The strength on this bottle is 20mg/ml, which is 2% nicotine by volume. In the UK, 20mg/ml is the legal maximum for nicotine e-liquid, and it is the same ceiling that applied to the liquid inside the disposable vapes that were sold before the single-use ban took effect on 1 June 2025. Bottle size is also capped, at 10ml for nicotine-containing liquid, and refill pods and tanks are limited to 2ml. This product sits at the top of the legal strength range and the top of the legal bottle size, so there is no stronger option available in the UK.

Nic salts feel different from freebase at the same strength. A 20mg freebase liquid feels harsh and is rarely used in mouth-to-lung devices, whereas a 20mg salt feels smooth enough to vape comfortably, and the nicotine reaches the bloodstream faster. That quicker response is why salts suit people switching from cigarettes: it gets closer to the satisfaction of a cigarette in a few puffs, so cravings are easier to manage.

As a broad starting point:

• 20mg/ml: suitable for people who smoke around 10 or more cigarettes a day, or who have their first cigarette within 30 minutes of waking. This is where most heavier smokers begin.
• 10mg to 12mg/ml: suitable for lighter smokers, people who have already cut down, and those who find 20mg too strong. Look for these in other bottles in the same range.
• 5mg or below: for people close to being nicotine free, or who vape mostly out of habit.

Signs that the strength is too high include nausea, dizziness, headaches, a racing heart, sweating or a very harsh throat. If you notice them, stop vaping, drink some water and consider moving to a lower strength. Signs that the strength is too low include persistent cravings, chain vaping and returning to cigarettes. Neither state is permanent. Strength can be adjusted over time, and many people step down gradually as cravings ease.

It is worth doing some simple arithmetic. A full 10ml bottle contains 200mg of nicotine. If you finish a bottle in four days, that is roughly 50mg of nicotine in the liquid per day, although a fraction of that is actually absorbed. If you are using a bottle in two days, you may be getting more nicotine than you did from cigarettes, and it is worth checking in with a stop smoking service or your pharmacist.

Vaping is substantially less harmful than smoking, according to NHS and public health bodies, but it is not risk-free and it is not intended for people who do not already use nicotine. It must not be sold to anyone under 18. If you want to quit nicotine altogether, free local stop smoking services in the UK can pair vaping with support, and they are worth using.

Who Zeus Bolt Cola Ice is for, and who should skip it

No single liquid suits everybody, and being straightforward about that saves you money. Zeus Bolt Nic Salts Cola Ice 20mg is aimed at a specific kind of adult user, so check whether the description below fits you.

It is a good fit if you:

• are an adult smoker moving to vaping and want a nicotine strength that actually replaces cigarettes
• already use a pod kit or refillable pod system and want a flavour that is not fruit or menthol
• enjoy sweet soda and dessert flavours, and like a bit of cooling on the exhale
• prefer a tight, cigarette-like draw to large clouds
• want a lower running cost than disposables, now that single-use vapes can no longer be sold in the UK

You should look elsewhere if you:

• are under 18, which makes it illegal for you to buy or be sold nicotine products
• do not currently smoke or vape, because there is no benefit to starting nicotine
• are pregnant or breastfeeding, or have a heart condition, high blood pressure or another health concern, in which case you should speak to a GP, pharmacist or stop smoking adviser first
• enjoy large clouds from a sub-ohm tank, because this liquid is built for low-power devices
• dislike sweet liquids, as cola flavours are naturally sweeter than tobacco, plain menthol or mild fruit blends
• find 20mg too strong, in which case a 10mg or 12mg bottle is a more sensible choice

A common situation worth addressing: people who have vaped for a while at 3mg or 6mg sometimes buy a 20mg salt by mistake because the price and bottle look the same. If that is you, do not move up to 20mg without a reason. It is a big jump, and the nausea and dizziness from over-nicotining are unpleasant. Check the strength printed on the front of the bottle before you buy, and again before you fill your pod.

There is also a middle group, dual users who vape and still smoke occasionally. For them, 20mg salts can help cut down cigarettes quickly because they deliver nicotine fast. The goal in that case should be to reduce smoking over several weeks, then drop the vape strength gradually afterwards, rather than staying at maximum strength indefinitely.

How to use it: filling, priming and settings

Using a refillable pod with nic salt takes a minute to learn and then becomes routine. Follow these steps for a clean first fill and consistent results.

• 1. Check compatibility. Confirm that your device is designed for nic salts or mouth-to-lung vaping, and that the coil resistance and wattage range suit a 20mg liquid.
• 2. Prepare your hands and surface. Wash your hands, lay down a paper towel, and open the bottle away from children and pets.
• 3. Remove the pod. Take the pod out of the battery section so you do not get liquid into the connectors.
• 4. Open the fill port. Most pods have a silicone bung on the side or top. Lift or slide it to expose the hole.
• 5. Fill slowly. Rest the nozzle against the edge of the port and squeeze gently. Stop at the maximum fill line, and never cover or flood the central airflow tube.
• 6. Close the port and wipe the pod. Push the bung fully back in place and wipe any liquid from the outside.
• 7. Wait. Leave the pod to stand upright for five to ten minutes so the coil wicks saturate. This is the step most people skip, and it prevents dry hits.
• 8. Start low. If your device is adjustable, set it to the lower end of the recommended range, take a few short puffs, and move up only if you want more flavour or throat hit.

Puffing technique matters for nic salts. Take a slow, gentle draw of two to three seconds, hold the vapour in your mouth briefly, then inhale into your lungs if you choose, or exhale directly. Long hard pulls waste liquid, overheat the coil and increase the nicotine you take in per puff. If the airflow on your device is adjustable, a tighter setting gives a more cigarette-like draw, while opening it up lowers resistance and cools the vapour slightly.

Pace yourself. With 20mg salts it is easy to take frequent small puffs without noticing the total, so some people find it useful to vape at set moments rather than continuously. When you feel a slight head rush, that is a sign you have had enough for now. Do not push through it.

When you swap flavours, empty the pod, rinse it with cool water if the manufacturer allows, let it dry and fit a fresh coil if the previous flavour was strong. Otherwise the two profiles blend and neither tastes right. If you are changing from Cola Ice to a fruit or plain flavour, a fresh coil is almost always worth it.

Troubleshooting common problems

Most issues with nic salts come down to priming, coil age, fill level or settings. These are the problems people report most often and the fixes that usually work.

• Burnt taste: usually a coil that has dried out or aged. Make sure the pod has liquid above the wicking holes, wait longer after filling, and drop the wattage a little. If the taste persists, fit a new coil.
• Weak or muted flavour: a coil clogged with sweetener residue is the common cause with sweet cola liquids. Replace it, and avoid chain vaping, which overheats the coil before it can re-wick.
• Dry hit or no vapour: the wick is not saturated. Refill, wait ten minutes, and take a few low-power puffs. If the device is auto-draw, check that the airflow is not blocked.
• Gurgling or spitting: there is too much liquid in the airflow path. Remove the pod and blow gently through the mouthpiece, wipe it clean and refill below the maximum line.
• Leaking: check that the pod is seated correctly, the fill port bung is fully inserted, and the pod is not overfilled. Cracks in the pod body also cause leaks, so inspect it. Store pods upright, and keep them out of hot places, because heat thins the liquid and pushes it past the seals.
• Throat harshness: either the wattage is too high or the strength is more than you need. Reduce power first, then consider a lower-strength bottle.
• Cooling too strong or too weak: adjusting wattage changes the balance. Lower power softens the cooling, higher power increases it.
• Nausea, dizziness or headache: stop vaping, drink water and eat something. If it recurs at the same strength, move to a lower nicotine level.
• Device will not fire: check that the pod is seated, the battery is charged, and the contacts are clean and dry. If the device has a lock mode, make sure it is not enabled.

A short list of habits prevents most of these issues: wait before the first puff after every refill, keep the pod no more than three-quarters full if your device tends to leak, change coils before they fail completely, and let a device cool for a few seconds between long sessions.

If you have tried these steps and the liquid still tastes wrong, check the batch number and expiry date on the bottle, and contact the retailer with a photo of the label. A properly sealed bottle that is within date should taste consistent from the first fill to the last.

Value for money

Value is more than the sticker price, so here is a fair look at the running costs of a refillable setup with a 10ml nic salt compared with cigarettes and with the disposables that used to dominate the market.

Ten-millilitre nic salt bottles in the UK are typically priced in the low single-digit pounds each, and many retailers offer multi-buy deals if you buy three or more. Check the price on the product page, because it changes with promotions. At moderate use of around 2ml a day, one bottle lasts about five days, so the liquid cost works out at somewhere in the region of a few pounds a week.

The other ongoing costs are coils and pods. A coil typically costs a couple of pounds and lasts one to two weeks with sweet liquids. A refillable device itself is a one-off purchase that varies widely, from modest starter kits to premium models. Even allowing for all of these, a regular smoker usually spends considerably less on a refillable vape than on cigarettes, which at current UK prices cost roughly £15 or more per pack, meaning a 20-a-day habit is well over £400 a month.

• Compared with cigarettes: substantially lower running cost for most smokers, and the liquid is usable in a device you keep.
• Compared with disposables: single-use vapes can no longer be sold in the UK, and even before the ban, refillable use worked out cheaper per puff once you had a device.
• Compared with pre-filled pods: refilling from a 10ml bottle is generally cheaper per ml than closed pods, at the cost of a little more handling.
• Compared with shortfills: shortfills are cheaper per ml but are built for low-nicotine, high-power use, so they are not a like-for-like alternative for a smoker who needs 20mg.

The honest negatives: a 20mg bottle is only good value if 20mg is the strength you need. A lighter smoker who buys 20mg and then finds it too strong has wasted money. The bottle size is also limited by UK law to 10ml, so you will go through bottles more often than someone buying 50ml shortfills. And sweet liquids shorten coil life, which is a hidden cost if you vape heavily.

On balance, for an adult smoker who needs a 20mg nic salt and enjoys a cola profile, Zeus Bolt Cola Ice offers sensible value as part of a refillable routine. The most reliable way to keep costs down is to match strength to need, store the bottle properly so it does not degrade, and replace coils before they affect flavour.

Honest comparisons with other 10ml nic salts

Zeus Bolt is one of many nic salt ranges in the UK market, and it is fair to compare it with others rather than pretend it has no competition. Prices and range details shift, so use this as a framework rather than a price list.

Brands such as Elf Liq, Hayati, IVG, Nasty Salt, Dinner Lady and Pod Salt all sell 10ml nic salts in 10mg and 20mg strengths, and all of them are sold under the same UK rules on bottle size, strength and labelling. Within that field, these are the points on which brands tend to differ.

• Brand recognition: larger names have more reviews, wider flavour lineups and more retailer stock. Zeus Bolt is a less prominent name, so you will find fewer independent write-ups to read before you buy.
• Flavour accuracy: cola is a difficult flavour to recreate. Some brands lean more heavily on citrus, others on vanilla and spice. Cooling levels also vary, from a faint chill to a strong menthol feel.
• Sweetness: some rivals are sweeter and more dessert-like, while others are drier. Sweeter liquids tend to gunk coils faster.
• Throat hit: two bottles at the same 20mg strength can feel different because of the nicotine source, the acid used for the salt and the PG ratio.
• Price: 10ml salts sit within a narrow band, and the difference between brands is often small enough that promotions matter more than the base price.

Where Zeus Bolt Cola Ice makes a fair case is the combination of a flavour that many fruit-led ranges do not cover well, the full 20mg strength, and the standard 10ml format that works in nearly any pod kit. Where it is less compelling is if you want a very large range of alternatives under one brand, or if you prefer a brand with a long track record you can check against other users' experience.

It is also worth comparing formats rather than only brands. A nic salt is better than a freebase for a pod kit at 20mg, because freebase at that strength is too harsh. A shortfill with added nicotine shots gives more volume for the money but is designed for higher-power devices and low strengths, and mixing it can be fiddly. Prefilled pods are tidier, but you are locked into one flavour and one manufacturer's device.

If you want to test whether you like the cola profile before committing to repeat orders, buy one bottle, use it with a fresh coil at low wattage, and judge it over a few days. If the cooling is too strong or the sweetness gets tiring, you have lost very little, and you can move to a different flavour using the same device and the same technique.
