Caliypso Blue Wave 100ml Shortfill Explained

Caliypso Blue Wave 100ml Shortfill E-Liquid is a nicotine-free, large-format bottle from the Caliypso range, listed at £7.99 with a single 0mg strength. It is a refill liquid rather than a device, so it needs a tank or refillable pod before it is of any use. The bottle is a 100ml size that is deliberately not filled to the neck, and that spare space exists so you can add nicotine shots if you want them, or leave the liquid at 0mg if you do not.

Blue Wave is one flavour in a long line of near-identical bottles. Caliypso sells its shortfills under four naming families, Surf, Wave, Ocean Lemonade and plain Lemonade, and Blue Wave is the blue-coloured entry in the Wave group. Every bottle shares the same price and the same 0mg listing, which makes comparison easy because the only real variable is the flavour you choose.

Why pick a 100ml bottle at all? Mostly value and convenience. Anyone who vapes daily gets through small 10ml bottles quickly, and each of those carries its own packaging, its own share of delivery weight and a price premium per millilitre. A large bottle spreads that cost out and gives you weeks of liquid from one order. The trade-off is that you need to be comfortable with a little home mixing if you want nicotine, and you need to be sure your hardware copes with the thicker liquids that big shortfills usually are.

This guide covers what a careful buyer should know before ordering: how the bottle works, what the flavour name does and does not tell you, how the range fits together, the arithmetic of adding nicotine, hardware pairing, storage, troubleshooting and delivery. Where we cannot state a fact from the listing, such as the exact VG to PG ratio or the precise liquid volume in the bottle, we say so and point you to the label, because the label is the authoritative source. This product is strictly for adults aged 18 or over, and if you add nicotine, please remember that it is addictive.

How the 100ml Bottle and Its Headroom Work

The words "100ml shortfill" describe the bottle's capacity, not necessarily the amount of liquid inside. A shortfill is sold short of full, so the bottle contains less e-liquid than it could hold. The label on your Blue Wave bottle states the true liquid volume, and with bottles of this style it is commonly 70ml or 80ml, leaving the remaining room free for nicotine shots. Always trust the printed figure over any assumption.

The reason for the format is regulatory. In the UK, e-liquid that contains nicotine may only be sold in bottles of up to 10ml, and the strength is capped at 20mg/ml. Nicotine-free liquid is not subject to the same bottle-size limit, so manufacturers sell big 0mg bottles and sell nicotine separately in 10ml shots. Combining the two at home is how many adults who prefer a freebase style of liquid buy in volume.

A nicotine shot is a 10ml bottle of concentrated nicotine in a VG and PG carrier, most often at 18mg/ml. You pour it into the spare headroom, close the cap and shake. Because the shot has a different thickness to the flavoured liquid, thorough shaking matters. Skip that step and the first few refills can taste or feel different from the last.

It helps to think of the bottle as a two-stage product. Stage one is the flavoured base, which is what you pay £7.99 for. Stage two is optional strength. If you vape at 0mg you are finished at stage one and can fill your tank straight away. If you want nicotine, the sections further down walk through the sums and the steps so there is no guesswork involved.

Most shortfills ship with a narrow nozzle fitted to the neck. That nozzle is what you use to fill tanks and pods, and it is usually a good match for the small filling ports found on modern devices. If you want to see the whole category in one place, our short fill e-liquids collection lists every size and brand we carry, so you can compare Blue Wave against other 0mg options before you commit.

What to Expect From the Blue Wave Flavour

Flavour is where an honest guide has to be careful. Our listing for Blue Wave gives a name and a colour but no published tasting notes, and we would rather say that plainly than invent a description. What we can do is explain how to read the name and how to judge the liquid once the bottle is in your hand.

In vaping, the word "blue" is a colour code more than a fruit. It usually signals a blue-themed profile, which in practice often means something in the blue raspberry, blueberry or berry-candy territory, but there is no fixed rule and brands interpret it differently. Compare that with names in the same family such as Cold Wave and Cold Surf, where "cold" hints at a cooling element. Blue Wave carries only a colour, so do not assume menthol or ice unless the label says so.

The practical way to judge a flavour like this is in three stages. First, smell the bottle after opening, because sweetness, berry notes and any sharp, candy-like top note are often easy to pick up before you vape a drop. Second, vape a freshly filled tank for a few puffs and pay attention to the inhale, which is where the headline flavour appears. Third, notice the exhale and the aftertaste, which tell you whether the liquid is sweet and rounded or leans tart and bright.

Shortfill flavours at this scale tend to be built for all-day vaping rather than a quick novelty hit, so the profile is generally designed to stay pleasant across many refills instead of tiring the palate. That is a general observation about the category and not a promise about this specific bottle, but it is a reasonable expectation for a liquid sold in a 100ml size.

Your own palate matters most. If you like fruit-led, sweet liquids, a blue-coded flavour is a sensible choice at this price, and the family described below gives you plenty of alternatives if it turns out not to be quite right. Give any new liquid a couple of full tanks before you judge it, since a fresh coil can need a little time to settle and early puffs are not always representative.

Where Blue Wave Sits in the Caliypso Family

Our catalogue holds more than thirty Caliypso lines, and almost all of them are 100ml shortfills at £7.99 and 0mg. Blue Wave belongs to the Wave group, whose colour variants include Black, Cold, Green, Orange, Pink, Purple, Rainbow, Red and Yellow alongside Blue. Understanding that structure turns a long list into a manageable menu.

The Surf group repeats the same colour idea with Black, Blue, Cold, Green, Orange, Purple, Rainbow and Red variants. Blue Surf and Blue Wave are therefore close neighbours by name, and a buyer who enjoys one is the likeliest to enjoy the other, though we would not promise they taste identical. If you are torn, nothing stops you ordering both and comparing them side by side.

The Ocean Lemonade group adds a lemonade twist to the colour names, with Blue, Deep Blue, Black, Green, Iceberg, Orange, Pink, Purple, Rainbow and Red entries. If you like the idea of a blue profile but prefer a lemonade character, Blue Ocean Lemonade and Deep Blue Ocean Lemonade are the obvious next stops. The plain Lemonade group is named in more literal terms, covering flavours such as Strawberry Lemonade, Pineapple Lemonade, Sweet Mango Lemonade, Triple Melon Lemonade and Tropical Punch Lemonade, so it is the easiest group to shop if you want to know the fruit in advance.

Because every bottle shares a price and a strength, switching between them is low risk. You can keep the same hardware, the same mixing routine and the same nicotine shots, and simply change the flavour. That makes the range a sensible choice for people who like variety and get bored of a single liquid after a week.

To browse the whole line in one go, open the Caliypso collection. If you would like to widen the search beyond one brand, the main e-liquids shelf lets you compare other makers, bottle sizes and nicotine types in a single view.

Who This Shortfill Suits, and Who Should Skip It

Not every liquid suits every vaper, and a 100ml shortfill is a more specific purchase than it first looks. Blue Wave makes the most sense for adults who already own refillable hardware and are comfortable topping up a tank or pod several times a week.

A good fit if you are:

• A daily vaper who gets through plenty of liquid and would rather buy it in volume than in small bottles.
• Someone who likes to set their own nicotine level, including anyone who wants to reduce strength gradually by adjusting how many shots go in.
• A 0mg vaper, because the bottle works exactly as supplied with no extra purchase.
• A fan of fruit-led, colour-named flavours who enjoys working through a range to find a favourite.
• Watching the cost per millilitre, since large bottles tend to work out cheaper to run.

Probably not for you if you are:

• A first-time buyer who wants a device to open and use straight away. A disposable vape is simpler, and a closed pod system sits somewhere in between.
• Using a closed pod kit with pre-filled cartridges, because those cannot be refilled with bottled liquid.
• Looking for 10mg or 20mg nic salt strengths. Shortfills are designed around freebase-style mixing at low strengths, and the nicotine salt e-liquids range is built for that job instead.
• Unwilling to measure, pour and shake, since adding shots is a few minutes of hands-on work.

A useful test is to ask what you vape on now. If the answer is a tank or refillable pod that you fill yourself, Blue Wave slots straight in. If it is a disposable, you would need to buy hardware first, which is a reasonable step up but not an impulse decision. As ever, vaping products are intended for adults who already smoke or use nicotine, and anyone who has never used nicotine has no reason to start.

Price, Volume and Cost Per Millilitre

At £7.99, Caliypso Blue Wave is priced identically to every other bottle in the range, which keeps the sums straightforward. Spread across a full 100ml the liquid costs just under 8p per millilitre, and if your bottle contains 80ml of liquid the figure is closer to 10p per millilitre. Either way, the unit price tends to sit below what small bottles cost once their packaging is factored in.

How long a bottle lasts depends on your habits and hardware. As an illustration only, someone who uses around 3ml a day would take nearly four weeks to finish 80ml, whereas a heavy user at 6ml a day would be reordering in under two weeks. Direct-to-lung setups with large coils consume liquid faster than mouth-to-lung pods, so measure your own usage for a week before planning a stockpile.

Nicotine shots are a separate cost. If you add them, the real price per millilitre of finished liquid rises slightly, though it generally remains attractive compared with buying the same volume in 10ml bottles. Check the current shot price on the shop before you order so your total is clear from the start.

Delivery is where a little planning pays off. Orders over £20 qualify for free UK delivery, and three bottles of Blue Wave come to £23.97, so a trio of 100ml bottles clears the threshold on its own. Mixing a few flavours from the range is a tidy way to do it, and it spares you from paying postage on a single bottle. Keep an eye on our vape deals page and the sale shelf for temporary offers, although a deal on this specific bottle is not guaranteed at any given time.

Finally, price is not the only measure of value. A cheap liquid that suits your tank poorly will waste money through leaks, burnt coils or a flavour you never really enjoy. Matching the bottle to your hardware, as covered below, protects your £7.99 better than any discount does.

Mixing Nicotine Shots Step by Step

If you only ever vape at 0mg, skip this part. If you want nicotine, the process is simple, and doing it carefully takes about five minutes. Read the label on both the shortfill and the shot before you begin, and work over a clean, dry surface.

• Step 1, check the headroom. Confirm on the label how much liquid the bottle holds and how many 10ml shots it is designed to take. Most 100ml shortfills are made for one or two.
• Step 2, open the bottle. Unscrew the cap and pull out the nozzle. Set both on a clean tissue so the nozzle does not pick up dust.
• Step 3, add the shot. Snip or unscrew the shot bottle and squeeze the contents into the shortfill. Pour slowly to avoid splashing, and tilt the bottle slightly if the neck is narrow.
• Step 4, refit the nozzle and cap. Push the nozzle back in firmly and tighten the cap fully so nothing seeps out while you shake.
• Step 5, shake well. Shake hard for around thirty seconds, then give it another shake after a few minutes. Different thicknesses blend slowly, and streaky mixing is the usual cause of uneven strength.
• Step 6, rest, then use. Let bubbles settle for a few minutes before filling your tank. Some people leave a freshly mixed bottle overnight, which is optional but harmless.

Label the bottle with the date and the strength you made, using a marker or a sticky label. It sounds fussy, but a week later you will not remember whether you added one shot or two, and an unlabelled bottle can be mistaken for something else.

Safety matters here. Concentrated nicotine should be kept out of reach of children and pets, and any spill on skin should be washed off with water straight away. Never decant liquids into unmarked containers, and keep unused shots in their original packaging until you need them. Nicotine is addictive, and mixing it yourself means the responsibility for getting the strength right is yours.

Choosing Your Nicotine Strength: The Maths

The strength of a mixed bottle follows one simple formula. Multiply the strength of each shot by its volume, add those together, then divide by the total volume of the finished liquid. Because the 0mg base contributes no nicotine, only the shots count towards the top line, while every bit of liquid counts towards the bottom line.

Here are worked examples that assume an 80ml liquid volume and 18mg/ml shots. They are illustrations, so always replace the numbers with the figures printed on your own bottles.

• No shots: 80ml at 0mg stays at 0mg.
• One 10ml shot: 18mg x 10ml = 180mg of nicotine in 90ml, which gives 2mg/ml.
• Two 10ml shots: 18mg x 20ml = 360mg in 100ml, which gives 3.6mg/ml.

If you have a different liquid volume, redo the sum. A bottle holding 70ml with two shots, for example, would finish at 90ml and a different strength, so the label figure really does matter. Shots at other strengths, such as 10mg/ml, change the answer again, and are worth considering if you want a gentler step.

What strength should you choose? There is no universal answer. Low strengths are the norm with shortfills because the liquids are usually paired with open, high-airflow hardware where each puff delivers a lot of vapour, and a high strength would feel harsh at that volume. Many adults settle in the range of 0mg to around 6mg. Beginning at the lower end and working up in small steps is more sensible than overshooting, since too much nicotine causes headaches, dizziness or nausea, and you can always add a shot later but cannot easily take one out.

If you want a clean 0mg bottle without any fuss, the nicotine-free e-liquids page collects the full selection. And if you ever find a ready-made higher-strength liquid easier than mixing, remember that nicotine salt liquids are sold at 10mg and 20mg, and the two approaches suit different devices, so it is worth knowing which your hardware prefers.

Tanks, Pods and Coils That Pair Well

Large shortfills are usually thick, high-VG liquids, and that shapes which hardware suits them. We cannot quote the exact VG and PG split for Blue Wave from the listing, so check the label, but as a rule of thumb a thicker liquid works best with wider wicking channels and lower-resistance coils.

Sub-ohm tanks are the natural partner. They are designed for direct-to-lung vaping, they take generous coil heads with big wicking holes, and they tolerate thick liquid without starving the cotton. Check the coil packaging for its recommended wattage and for the VG range it is rated for, and never exceed the stated limit. A fresh coil should be primed by dripping a few drops directly onto the cotton and letting it soak for several minutes before the first puff, otherwise it can burn.

Refillable pod systems can work too, provided the pod and coil are designed for the thickness of the liquid. Some compact pods use tighter coils that wick slowly, and a very thick liquid can leave them gurgling or producing dry hits. If your kit's manual recommends a particular VG percentage, follow it. Our refillable vape pods shelf is a good place to see what is available, and replacement coils are stocked for a wide spread of tanks and kits.

If you do not yet own suitable hardware, browse the vape kits category and look for tanks that list a refillable top fill and a wide coil option. A kit with a replaceable coil is usually the better long-term buy for shortfills, because you can swap coils as they wear out instead of replacing the whole device.

The one category that does not work at all is anything sealed. Disposables and closed pod cartridges are pre-filled and not designed to be opened, so a bottle of Blue Wave cannot be used in them, and trying to force liquid into them is both unsafe and a waste of good liquid.

Storing, Shaking and Looking After the Bottle

A 100ml bottle will sit on your shelf for weeks, so storage deserves a few lines. Liquids are made of simple ingredients, but heat, light and air will all change them over time, and good habits keep the last millilitre tasting like the first.

Store the bottle upright in a cool, dark place, such as a drawer or cupboard away from windows and radiators. Direct sunlight and warm conditions can darken the liquid and dull the flavour, and a bottle left in a hot car for an afternoon is the quickest way to spoil it. A gentle colour change over time is normal, especially for fruit flavours, and is not necessarily a sign that anything is wrong, although a sharply different smell or taste is a good reason to stop using it.

Keep the cap on tight whenever you are not filling. Air exposure encourages the liquid to thicken and lose its top notes, and an uncapped bottle is a spill waiting to happen. Wipe the nozzle clean after each fill so residue does not harden around it, and never leave the nozzle sitting in an open pod or tank where it can pick up debris.

Shake the bottle gently before refilling. Larger bottles can settle a little, particularly if you have added nicotine, and a quick shake makes sure each tank gets an even mix. If you made a batch with shots, store the bottle separately from anything that looks like food or drink, and keep it clearly labelled with the strength and date.

Finally, think about the end of the bottle. Check the printed batch and best-before information on the label, and use older stock first. If you stockpile several flavours, keep them in the original cartons with the labels facing out, so you can identify them at a glance. A little tidiness here will save you from refilling your tank with the wrong flavour when you are in a hurry.

Pros, Cons and Common Troubleshooting

No product is perfect, and a fair summary helps you decide. On the plus side, Blue Wave offers a large volume for a modest £7.99, a nicotine-free base that works as supplied, flexibility to add shots at a strength you choose, and a range of sibling flavours at the same price. The sizing also reduces the number of orders you place and the amount of small-bottle packaging you throw away.

On the minus side, the bottle is not a ready-to-use device, so you need compatible hardware. The liquid will not suit sealed disposables or closed pods. Adding nicotine takes some effort and care, and the flavour description is limited to a colour-coded name, so a first-time buyer is taking a small gamble on taste. The ratio of VG to PG may also not suit very small pod kits.

When something goes wrong, work through the usual suspects before blaming the liquid.

• Gurgling or spitting: often too much liquid in the tank or condensation in the airflow. Wipe the tank, check the fill level and make sure the coil is seated correctly.
• Dry or burnt hits: usually an unprimed or worn-out coil, or a tank that has run too low. Replace the coil and prime it properly.
• Leaking: typically a loose seal, an over-filled tank or a cracked pod. Check the O-rings and tighten the base.
• Flavour seems faded: try a different flavour for a day or two, because palate fatigue is common. Also check the coil age.
• Nicotine feels uneven: if you added shots, shake thoroughly again and let the bottle rest.

If a problem persists, stop using the product and double check your device manual. Our team can also help via the contact page if you are unsure what went wrong.

Delivery, Age Checks and Buying With Confidence

Buying vaping products online involves a few extra steps, and it helps to know them in advance. Vaping products are restricted to adults, so you must be 18 or over to order, and we may ask you to confirm your age as part of the process. Our age verification page explains what is required and why, so there are no surprises at checkout.

Orders placed before 4pm are dispatched the same working day, and UK delivery is free on orders over £20. Because a single bottle of Blue Wave costs £7.99, you will need to add a little more to reach that threshold. As noted above, three bottles come to £23.97, so a small multi-flavour order from the range does the job neatly. The shipping information page sets out the delivery options, timings and any cut-off details in full, and it is the page to check if you have a specific date in mind.

Every product we sell is 100% genuine, supplied through legitimate UK channels, which matters with e-liquid because counterfeit or unlabelled liquids are a real risk in the wider market. When your parcel arrives, check that the seal is intact and the label is legible, and that the flavour and strength match your order. The label is also where you will find the batch information, the ingredient list and the required warnings.

If anything is missing, damaged or not what you ordered, get in touch with us promptly and keep the packaging so we can investigate. Our FAQ page covers the most common questions about orders, returns and payments, and the contact page is there for anything it does not answer.

Lastly, a reminder about responsible use. Keep your liquids and nicotine shots out of the sight and reach of children and pets, and do not share them with anyone under 18. If you are unsure about anything on the label or in this guide, ask before you use the product.
