Caliypso Black Wave 100ml Shortfill at a Glance

Caliypso 100ml Shortfill E-Liquid Black Wave is a large bottle of nicotine-free vape juice from the Caliypso range, priced at £7.99 and listed at 0mg. That 0mg figure is the defining trait of a shortfill. The nicotine is left out on purpose, and the bottle is made with spare headroom so an adult vaper can add nicotine shots later if they want a strength. Leave it as supplied and you simply have a nicotine-free e-liquid.

Black Wave is one of 37 listings from the brand, and every one of them sits at £7.99 and 0mg. That is worth knowing before you start comparing. Price and strength do not change from one flavour to the next, so the real decision is which name appeals and whether a 100ml bottle suits the way you vape.

What you are buying here is volume. A bottle this size lasts a regular tank user a good while, and the cost per millilitre is a fraction of what small bottles command (the sums come later on this page). What you are not buying is hardware. There is no battery, coil or tank in the box, because the item is liquid and nothing else.

It also helps to know what the bottle is wrong for. Shortfills are made for refillable devices, sub-ohm tanks in particular. A sealed disposable vape cannot be topped up with one, and a closed pod system that accepts only its own cartridges will not take one either. Match the liquid to the kit before you reach the checkout and you avoid the most common mistake with this format.

The sections below cover how a shortfill bottle works, how to approach the flavour when the listing is light on tasting notes, what the numbers look like, how to fill a tank, how to add nicotine if you choose to, and the practical matters of storage, troubleshooting and delivery. Everything we sell is strictly for adults aged 18 and over, and that applies to nicotine-free products just as it does to the rest of the range.

How a Shortfill Bottle Actually Works

Shortfill is trade shorthand for a bottle that is deliberately not full to the brim. The liquid inside is sold at 0mg, and the empty space at the top is there for a reason: it lets you drop in one or two separately sold nicotine shots and shake the bottle until they blend through. The maker supplies a nicotine-free base, and you decide whether it stays that way.

Why does the format exist at all? Across the UK market, e-liquid that contains nicotine is sold in bottles of no more than 10ml, which is why a standard nicotine bottle looks so small. Nicotine-free liquid is not held to that bottle size, so 0mg juice can be sold in big bottles at a much lower cost per millilitre. A shortfill is the route that lets an adult buy a large volume cheaply and still reach a nicotine strength afterwards, simply by adding shots. It is a market-wide convention rather than something particular to one brand.

Before you do any arithmetic, settle what the "100ml" in the product name refers to. On the listing it is the headline size. The label on the bottle you receive is the authority on liquid volume, bottle capacity, VG/PG ratio and batch details, so read it before you work out how much room you have for shots. We have not quoted a VG/PG split on this page because the listing does not state one, and we would rather leave a gap than guess.

Shortfills of this kind are normally formulated with tank-style hardware in mind. Tanks with wider airflow and bigger coils cope well with thicker liquid, which is why shortfills are the usual pick for sub-ohm users. Once again, confirm against the label rather than assume.

Once the format makes sense, comparing bottles gets easier. If you want to see how Caliypso stacks up against other makers, the wider shortfill e-liquids shelf sets the competition out side by side, and every bottle there follows the same logic described above.

Reading the Black Wave Flavour Name

The listing names a single flavour, Black Wave, and does not spell out tasting notes. That deserves a plain statement, because plenty of product pages build an elaborate taste description from a name alone, and a name is a poor guide to what is actually in the bottle. What we can say with confidence comes from how the range is organised.

Caliypso sorts most of its 37 listings into patterns. There is a Wave group of ten (Black, Blue, Cold, Green, Orange, Pink, Purple, Rainbow, Red and Yellow), a Surf group of eight, and an Ocean Lemonade group of ten that includes Deep Blue and Iceberg variants. Add eight standalone lemonade and fruit names, such as Original Lemonade, Strawberry Lemonade and Tropical Punch, plus one base listing with no flavour in its title, and you have the full set. Black Wave belongs to the first group, and the colour is the part that changes from one bottle to the next.

The flavour tags across the whole Caliypso collection point to a fruit and lemonade lean: lemonade, lemon, orange, cherry, lime, pineapple, apple, strawberry, mixed berries, mango and tropical fruit, with ice as a recurring theme. That tells you about the line as a whole. It does not tell you which of those directions Black Wave takes, and we are not going to pretend that it does.

Here is a sensible way to approach a flavour you cannot read in advance. Fill the tank, give the coil its priming time, and judge across the first few millilitres rather than the first puff. A fresh coil can taste slightly muted or odd for the opening minutes. Flavour also shifts with wattage and airflow. A lower setting usually gives a cooler, gentler vape with more of the character coming through, while a higher setting tends to push warmth and sweetness to the front.

If you have already tried a neighbouring name in the same group, treat that as a loose hint at the house style and nothing more. Sharing a word in the title is not a promise of a shared taste. Finally, check the bottle itself for any flavour description printed on the packaging, since a label can carry more detail than a shop listing has room for.

Who This Bottle Suits and Who Should Skip It

Picture an adult who already owns a refillable tank and gets through a fair amount of juice every week. That person is the natural buyer for a 100ml shortfill. They are tired of emptying 10ml bottles every few days, they like the idea of a lower cost per millilitre, and they are comfortable with the routine of filling a tank, priming a coil and wiping the odd drip off the threads.

A second group is the nicotine-free crowd. Some adults have moved away from nicotine altogether but still enjoy the flavour and the habit of vaping, and a 0mg shortfill suits them without any extra steps. A third group likes to control their own strength, adding a shot or two to land exactly where they want, or none at all, depending on the day.

Now the people who should look elsewhere. If your device is a sealed disposable, this is not for you; you will find a far better match among the sealed disposables we stock. If you use a closed pod kit with proprietary cartridges, the same applies. And if you want a bottle that arrives already at a nicotine strength, remember that this one is 0mg out of the box, so you would need to buy shots separately or choose a different product.

Refillable pod systems sit in a grey area, so take care there. Some are happy with thicker shortfill juice and some are not, because a small coil and a narrow wick can struggle with a high-VG liquid. If your kit falls into that category, browse the refillable vape pods and read the manufacturer's guidance on liquid thickness before you commit to a large bottle.

Lastly, a point we repeat on every page: nicotine-free does not mean child-friendly. We sell to adults aged 18 and over only, and orders go through an age check regardless of strength. If you are new to vaping and want the simplest possible start, a prefilled option with no filling or coil priming may be less fussy than a bottle and a tank.

The Numbers: Price, Volume and Cost Per Day

Start with the figures the listing does give. The price is £7.99. The strength is 0mg. The headline volume is 100ml. There is no puff count, because a bottle of liquid has no built-in puff count, and the listing carries no deal tag. If a number is not on the product page or the bottle label, we have not made one up here.

The first calculation is cost per millilitre. £7.99 across 100ml works out at roughly 8p per millilitre. To see why that matters, imagine a 10ml nicotine bottle priced at £2.99, which is a made-up figure used purely for illustration. That comes to nearly 30p per millilitre, close to four times as much. The gap is the reason people with high-use habits move to shortfills in the first place, and the reason this format has become so common.

The second is how long a bottle lasts, and this depends entirely on you. Consumption varies enormously with device, wattage and habit. For illustration only, take three tank users. A light one getting through 3ml a day would take about a month to finish 100ml. A moderate one at 5ml a day would finish in about 20 days. A heavy one at 8ml a day would be done in roughly 12 days. Those are examples, not measurements, so track your own usage over a week and divide.

The third is cost per day. At the same three rates, the liquid costs about 24p, 40p and 64p a day respectively, before any extra spending on coils, batteries or nicotine shots. Add the shots if you use them, because those are priced separately and nudge the real figure upwards. Coils are the other recurring cost, and they wear faster with sweeter juices.

If you buy several bottles at once, check where the savings really sit. The 5 for £10 e-liquids shelf is where small bottles are bundled at a lower price, but this particular product carries no multibuy tag, so do not assume that offer applies to a 100ml bottle. The product page and your basket will always show the price you will actually pay.

Filling a Tank Step by Step

The process is simple once you have done it twice, though the first attempt tends to feel clumsy. Because tanks differ, always keep the manual for your own device to hand, particularly if it fills from the bottom rather than the top. The steps below apply to the typical top-fill tank.

• Prepare. Wash and dry your hands, and place a tissue or small towel on the table. Make sure the tank is empty or nearly empty and that the device is switched off.
• Open the tank. Unscrew the top section or slide back the fill port cover, following your manual. Keep the central airflow tube clear of liquid at all times.
• Prime the coil. Fresh coils need to be soaked. Add a few drops directly into the coil head's openings, then fill the tank and wait five to ten minutes so the cotton can absorb liquid properly.
• Fill carefully. Tilt the tank slightly and run the liquid down the inside wall rather than pouring straight in. Stop a little below the maximum line, because liquid expands slightly with temperature.
• Close up and wipe. Reseal the tank, wipe the threads and mouthpiece, and stand it upright for a few minutes.
• Start gently. Take a few gentle draws without pressing the fire button, which pulls liquid into the wick, then begin at the lower end of the coil's recommended wattage range.

If you plan to add nicotine shots, do it in the bottle before filling the tank, not in the tank. Pour out a small amount of the shortfill if the bottle lacks room, add the shot or shots, close the cap tightly and shake thoroughly. Then let the mixed bottle rest for a while, ideally a day, so the nicotine blends evenly.

A few final habits save trouble. Never fill past the maximum marker. Never leave an uncapped bottle standing. And keep the nozzle clean, because dried residue in the tip causes drips on the next use. These are small things, but they are the difference between a tidy routine and sticky fingers.

Nicotine Strength Options for a 0mg Shortfill

Out of the bottle, this product is 0mg, full stop. Any nicotine in your final mix is something you add yourself, using separately sold nicotine shots. If you want to stay at zero, that is entirely fine, and the nicotine-free e-liquids shelf shows what else is available at that strength.

For those who do add nicotine, the sum is straightforward. Take the total milligrams of nicotine you are adding, then divide by the total volume of liquid once everything is mixed. As an example, if a bottle holds 100ml of liquid and has room for two 10ml shots of 18mg/ml, the finished 120ml contains 360mg of nicotine and comes out at 3mg/ml. That example is only an illustration, because the actual headroom on your bottle is printed on the label and may differ. Always do your own sum with your own numbers.

Strength choice depends on the device. Sub-ohm tanks deliver big clouds of vapour with a wide, open pull, so adults who use them and want some nicotine commonly land at the lower end of the scale. Tighter, mouth-to-lung devices behave differently and usually pair with stronger liquids. Given the large airflow typical of the tanks this bottle suits, going stronger than you need in a sub-ohm setup can feel harsh in the throat quickly, so start low and adjust.

It helps to understand that this is a different animal from nicotine salt liquid. Nic salts are sold in 10ml bottles at set strengths such as 10mg or 20mg and are designed for small, low-power pod devices. You will find them on the nicotine salt e-liquids shelf. They are not an add-on for a shortfill, and mixing the two is not something we recommend without clear guidance from the maker of your shots.

Under UK rules, nicotine-containing e-liquid has a ceiling of 20mg/ml, and a shortfill with shots added will normally land well below it. Nicotine is addictive, and no one who does not already use nicotine should start. If you are unsure which strength fits, begin at the lowest you can tolerate rather than the highest.

Hardware That Pairs Well With This Bottle

A shortfill is only ever as good as the tank it goes into. The usual match is a sub-ohm tank, which pairs a low-resistance coil with generous airflow and a large reservoir. Those tanks handle thicker liquid with ease, and they are designed to consume a lot of it, which is exactly why a 100ml bottle makes sense rather than a stack of small ones.

If you do not own a tank yet, the vape kits category is the place to start. Be careful to pick a refillable kit rather than a closed pod system, as product descriptions make the difference clear. A kit that includes a sub-ohm tank, a battery mod and a spare coil gives you everything you need except the liquid itself, so a bottle like this completes the set.

Coils deserve a separate mention. They are the part that wears out first, and sweeter or darker liquids tend to shorten their life. Keep a spare or two in a drawer, and match the coil to your tank model, since coil heads are rarely interchangeable across brands. The coils shelf lists replacement heads, and each tank's wattage range printed on the coil tells you where to set your device. Going below that range gives a weak, lukewarm vape, and going above it risks a burnt taste.

There are sensible upgrades beyond the basics. A second tank lets you keep two flavours on the go without rinsing between them. A small empty dropper bottle is handy for carrying a day's supply in a bag, so you do not need to take the large bottle out with you. A different drip tip changes the feel of the draw, and a spare battery stops the device running flat just when you want it.

Finally, remember the compatibility point from earlier. Check the liquid's VG/PG ratio on the label, then check what your coil is designed to handle. Higher-VG juice suits larger coils and airflow, while thinner juice suits tighter draws. Matching the two keeps wicking healthy and flavour consistent from the first tank to the last.

Storing the Bottle So It Stays Fresh

Heat, light and air are the three things that age e-liquid fastest, and keeping all three at bay is easier than it sounds. Store the bottle upright with the cap screwed on firmly, in a cool, dark place such as a cupboard or drawer. A bedside table in direct sunlight, a windowsill or the shelf above a radiator is a poor choice, and so is the glove box of a car on a warm day.

Keep the liquid in its original bottle. The label carries the batch information, the ingredients and the best-before date, and you will want that if you ever need to check something or contact us. If you decant into a smaller dropper bottle for carrying around, label it clearly with the flavour and the date. Never use a food or drink container, however temporary the arrangement feels.

If you have added nicotine shots, write the date and the final strength on the bottle with a permanent marker. It sounds fussy, but it is easy to lose track once a few bottles are open, and mixed strengths are not something you want to guess at. Do the same when you share a household with other adults who vape.

Keep all e-liquid well out of reach of children and pets. Nicotine-free juice is still not something to be swallowed, and a sweet-smelling bottle can be tempting to a curious child. A high shelf or a lockable box is a sensible habit, and the cap should always be fully closed after use.

Over time, a bottle may darken slightly. That is common with many flavoured liquids and usually reflects ageing of the flavouring rather than a fault, though a strange smell or a separated, cloudy appearance is a reason to stop using it. Shake the bottle gently before each fill, particularly if shots have been added, so the mix stays even. A fridge is unnecessary, and in fact the cold can thicken the liquid and make it slow to pour.

Honest Pros and Cons of This Format

No format is perfect, and shortfills have a fairly clear set of trade-offs. Here is the balanced picture, drawn from how this product is listed and how the category generally behaves.

The good points

• Low cost per millilitre. At £7.99 for 100ml, the liquid costs roughly 8p a millilitre, which is far below the price of small bottles.
• Fewer bottle changes. One large bottle replaces a stack of small ones, which means less waste and fewer top-up orders.
• Control over strength. You can stay at 0mg or add shots to reach a level of your choosing.
• Consistent price across the range. All 37 Caliypso listings cost the same, so picking a flavour never involves a price trade-off.
• Suited to tank users. It is designed for refillable hardware that burns through liquid.

The drawbacks

• Not for every device. It will not work in a sealed disposable or a closed pod kit, so a wrong purchase is easy to make if you are not paying attention.
• Some effort required. You fill the tank yourself, prime coils and clean up the odd drip.
• Nicotine is your job. If you want a strength, you must buy shots separately and do the sum yourself.
• Flavour is unproven until you try it. The listing gives no tasting notes, so the first tank is a trial.
• Bulk commitment. A big bottle is a lot of one flavour if you get bored easily.

Weighing it up, the format rewards people who already know their hardware and use it daily. For occasional vapers or anyone who dislikes handling liquid, the convenience of a simpler product may count for more than the saving.

Troubleshooting Common Tank Problems

Most complaints about a new bottle turn out to concern the hardware rather than the liquid. Before you decide a flavour is at fault, run through the usual suspects, because the fix is nearly always quick.

Gurgling or spitting. This usually means condensation or an overfilled tank. Blow gently through the drip tip to clear it, wipe the mouthpiece and keep the fill level a little below maximum.

Leaking. Check the seals, make sure the tank is screwed together tightly, and look for hairline cracks in the glass or plastic. Over-tightening can also damage the O-rings, so firm is enough. Store the tank upright when not in use.

Burnt or harsh taste. The coil is probably dry or worn. Let the tank sit for a few minutes after filling, take shorter puffs with pauses between, and replace the coil if the taste does not improve. Also check that your wattage sits inside the coil's recommended range.

Muted flavour. A tired coil is the most common cause, followed by taste fatigue from vaping one flavour all day. Swap in a fresh coil, rinse the tank and take a break from the flavour for a few hours before judging it again.

Dry hits. If the vapour feels hot and thin, the wick is not getting enough liquid. Prime again, lower the power and check that the airflow slots are not blocked by liquid.

Harsh throat feel after adding shots. The mix may be stronger than you intended, or poorly blended. Recheck your sum, shake thoroughly and let the bottle rest. If the strength is still too high, add more unmixed shortfill to dilute it.

If a problem sounds like a fault with the bottle itself, such as an odd smell, leaking at the nozzle or a damaged seal, stop using it and get in touch with the team. Have your order number and the batch details from the label ready, plus a photo if you can, and it will be much quicker to sort out.

Delivery, Age Checks and Buying Information

Buying a 100ml bottle online is straightforward, but a few practical points are worth setting out before you order. Weekday orders placed before 4pm are dispatched the same day, and UK delivery is free once your basket reaches £20. Anything below that threshold carries a delivery charge, and the available options are shown at checkout so there are no surprises at the last step.

Every order for this product goes through an age check, as this is an adult product whether or not it contains nicotine. We explain exactly how it works on the age verification page, and having your details ready makes the process quick. Orders that cannot be verified will not be dispatched, which protects both you and us.

All stock is 100% genuine, which matters more with e-liquid than with most purchases. Counterfeit bottles exist across the wider market, and a low price from an unknown seller is the usual warning sign. When your parcel arrives, check that the bottle is sealed, the label is legible and the batch information is present. If anything looks wrong, do not use it.

On returns, e-liquid is a product people vape, so opened bottles generally cannot be sent back for hygiene reasons, in the same way as most consumable goods. Faulty or incorrectly supplied items are a different matter and should be reported promptly. The full terms on delivery times, tracked options and what to do if something goes wrong are on the shipping information page, and that is the place to check before you order if you have a specific question.

To summarise the whole decision in a few lines: choose Black Wave if you own a refillable tank, want a large nicotine-free bottle at a low cost per millilitre, and are happy to find out the flavour for yourself. Choose something else if your device is sealed or closed. Whichever you pick, store it properly, fill it carefully, and keep it away from anyone under 18.
