CaliypsoThe Red Ocean Lemonade Caliypso 100ml Shortfill E-Liquid by Caliypso in Red Ocean Lemonade at 0mg. Free UK delivery over £20, same-day dispatch on weekday orders before 4pm.
Caliypso 100ml Shortfill E-Liquid Red Ocean Lemonade is a nicotine-free vape juice in a large bottle, priced at £7.99. It belongs to the Caliypso e-liquid range, a line of more than thirty flavours that all share the same bottle size, the same price and the same 0mg strength as supplied. Because those practical details never change from one bottle to the next, choosing a Caliypso comes down to flavour and very little else.
It helps to be precise about what you are buying. This is loose liquid, not a ready-to-use device. There is no battery in the box, no coil, no tank and no pod. You pour the juice into a refillable vape that you already own, or that you buy alongside it. Anyone hoping for something that works the moment it arrives should read the section on who this bottle suits before ordering.
The word shortfill describes the packaging rather than the taste. A shortfill is a bottle that is deliberately not filled to the brim, leaving spare space so that you can add nicotine shots later if you want to. Left alone, the bottle stays at 0mg. People who vape without nicotine buy shortfills for that reason, and so do people who like to mix a strength of their own. If you would like to compare other brands and flavour families before settling, the short-fill e-liquids collection is the place to browse.
Red Ocean Lemonade sits in a colour-coded family inside the Caliypso lineup. The product listing tags it as lemonade and lemon, which is the most reliable clue to its direction. Later sections on this page separate what the listing tells us from what we would only be guessing at, because a flavour description you cannot trust is worse than none at all.
Everything here is written for adults. Vaping products are strictly for people aged 18+, and nothing on this page is medical advice or a claim about health. If you are new to refilling, read the sections on how shortfills work and on filling a device step by step before you order. A few minutes of preparation prevents most of the spills, flooded coils and wrong-strength mixes that catch out new users, and it makes the first bottle far more enjoyable.
UK law is the reason this format exists. Nicotine-containing e-liquid may only be sold in bottles of 10ml or smaller, and refillable tanks are capped at 2ml. Nicotine-free liquid is not held to the 10ml bottle limit, so a maker can fill a much bigger bottle provided it ships at 0mg. That is why a 100ml bottle and a 0mg strength always travel together on a product like this one.
The clever part is the empty space. A shortfill contains less liquid than the bottle could hold, and the gap is there so that you can top up with nicotine shots bought separately. A shot is a small 10ml bottle of concentrated nicotine liquid, commonly sold at 18mg/ml. Tip it into the shortfill, press the cap back on, shake well, and you have a larger bottle at a strength you chose rather than one a manufacturer picked for you.
How much liquid sits inside, and how many shots will fit, is printed on the label. We deliberately do not quote those figures from memory, because they can differ between packaging runs and an inaccurate number could lead to a wrongly mixed bottle. Read the label first, then do the sum. The shot maths section further down shows exactly how.
It also helps to know what a shortfill is not. It is not a nicotine salt liquid, which is the format designed for small, low-power devices and sold in 10ml bottles at a stated strength. If that sounds closer to what you want, the nicotine salt e-liquids collection is the right place to look. Nor is a shortfill a disposable, because nothing about it is sealed, sized or charged for you.
If you only ever want flavour with no nicotine at all, a shortfill is a very economical shape for that, and you will find more bottles built the same way in the nicotine-free e-liquids range. Whichever route you take, remember that the larger the bottle, the more important good storage and clear labelling become, topics we return to later on this page.
Bottle names are part description and part marketing, so it pays to read this one with some care. The product listing tags Red Ocean Lemonade as lemonade and lemon. Those two words are the firmest evidence we have about its direction, and they point to a citrus-forward juice in the style of a sweetened, slightly tart lemon drink rather than a creamy, minty or tobacco-style profile.
Inside the Caliypso lineup the names follow a pattern. Several flavours carry the words Ocean Lemonade after a colour, including Blue, Black, Green, Orange, Pink, Purple, Rainbow, Deep Blue and Iceberg, alongside this Red one. Another group uses Surf and Wave in the same colour-led way. The colour is best treated as a family marker that helps you tell the bottles apart. We do not have a manufacturer tasting breakdown confirming which fruit, if any, the red refers to, so we are not going to invent one.
What we can describe is what lemonade liquids tend to do in general. A good one opens with a bright, slightly sharp citrus note, follows with sweetness that rounds the edge off, and finishes quickly rather than lingering on the tongue. Vapour temperature changes the picture. Cooler, lower-power vaping usually keeps the citrus crisp, while hotter settings tend to push the sweetness forward and flatten the sharp top note.
If you enjoy shop-bought lemonade, a tangy cordial or a sherbet sweet, this is the flavour family you are most likely to get on with. If sour tastes make you wince, consider whether a gentler fruit juice from another line would suit you better. Neither choice is wrong, and at £7.99 the cost of finding out is modest.
A practical way to judge any new bottle is to give it a fair trial. Fill a fresh or newly primed coil, take your first few puffs gently, and then vape it for a day or two before forming an opinion. Your palate adjusts quickly, and the first impression of a sharp liquid can be harsher than the tenth. Jot down what you notice about sweetness, sharpness and finish, and you will have a much clearer idea of which Caliypso bottle to try next.
Start with the people for whom this bottle is a natural fit. Adults who already own a refillable pod system or tank will find it straightforward, because the job is simply pouring liquid into hardware they know. So will anyone who likes lemon and lemonade flavours, who prefers a nicotine-free bottle, or who likes to mix a strength of their own using separate shots. Anyone who dislikes buying a new sealed device each time the flavour runs out will also see the appeal of a refill format.
Value-minded shoppers are another obvious audience. The whole Caliypso range sits at one price, so there is no premium to pay for the flavour you happen to prefer. If you go through juice at a steady pace, a large bottle spreads its cost over many fills compared with small pre-filled cartridges, and you are free to change the strength whenever you like.
Now for the people who should look elsewhere. If you have never vaped and simply want something that works straight from the packet, a refill bottle will feel like homework. Our disposable vapes are built for exactly that situation, with the liquid, coil and battery already sealed together. They are a different product at a different price, but the convenience gap is real, and there is no shame in choosing the simpler route.
Closed pod owners should also pause before buying. Many pod kits accept only sealed, pre-filled pods and cannot be refilled at all, so a shortfill bottle would have nowhere to go. Check your device manual or its listing first. If you are unsure whether your hardware has a fill port, ask the shop team before you order rather than after.
Finally, a clear word on who this is not for. Vaping is intended for adults who already smoke or vape. Anyone under 18, and anyone who has never used nicotine and has no reason to start, should leave it alone. Because this bottle ships at 0mg there is no nicotine in it as supplied, but the flavourings and the habit of inhalation are still good reasons for non-users to steer clear. If you are unsure whether vaping is appropriate for your circumstances, speak to a pharmacist or doctor.
Here is everything we can state with confidence, taken straight from the product listing.
Just as important is what that list leaves out. We do not publish a VG to PG ratio, the exact millilitres of liquid inside the bottle, the flavouring concentration or the bottle shape, because the listing does not confirm them. The label on the bottle is the authority on all of those points, so read it before your first fill and before you buy any shots.
A word on value is worthwhile. Divide £7.99 by 100 and you get just under 8p per millilitre, but that figure covers the whole bottle, headroom included. Your real cost per millilitre of liquid is higher, and the exact amount depends on the liquid volume printed on the label. When you compare against another brand, compare liquid volumes rather than the number in the product name. If you enjoy hunting for offers, the vape deals collection gathers current promotions in one place.
Puff counts do not apply to a bottle. Those numbers belong to disposables with a fixed internal capacity. How long a bottle lasts depends on your device, your coil, your power setting and your habits, so any page that quotes a single figure for bottle life is guessing. A light user will stretch one bottle across a long stretch of time, while a heavy user at higher power can empty the same bottle far sooner. Treat the label volume as your real budgeting figure and keep a spare to hand.
Filling is easy once you have done it twice, and a calm, tidy first attempt sets a good habit. Work on a flat surface with a tissue or paper towel nearby, because small spills are normal and a little liquid on the fingers is simple to wipe away. Follow these steps in order.
If you do not yet have any hardware, pod kits are the simplest place to begin, because the pod, coil and battery are designed to work together. When your pod eventually wears out, the refillable vape pods range covers replacement pods that carry a fill port. Always check compatibility with your exact device before ordering, since pods are rarely interchangeable between brands and even between models from the same maker.
Cleaning up afterwards takes seconds. Wipe the bottle neck, put the cap back on firmly and return it to its storage spot. If liquid has crept into the airflow channel of a pod, tip it out onto tissue before you vape. Flooded airflow gives a gurgling sound and a spitting hit, and it is the commonest reason a fresh fill feels disappointing. Patience at this stage pays back with a smoother vape.
Strength is arithmetic, and once you see the formula it stops being mysterious. Multiply the number of shots by 10 (the millilitres in each shot) and then by the shot strength, to get the total milligrams of nicotine you are adding. Divide that by the total volume of liquid after mixing. The answer is the finished strength in mg/ml.
Here is a made-up illustration that has nothing to do with your actual label. Imagine a bottle that holds 80ml of liquid. Add one 18mg/ml shot and you have 180mg of nicotine in 90ml, which works out at 2mg/ml. Add two shots and you have 360mg in 100ml, which is 3.6mg/ml, provided the bottle really has room for both. Different bottles start with different volumes, which is why the numbers on your own label matter far more than any worked example on a web page.
You can also leave the bottle alone. At 0mg it is a perfectly usable nicotine-free liquid, and many adults prefer it that way. If you would rather not do any mixing at all, ready-made nicotine salt bottles arrive at a stated strength, though they are a different format designed for low-power pod systems and do not behave like a shortfill.
A few habits make mixing safer and more predictable:
Nothing here is medical advice, and we do not recommend any particular nicotine level. If you are an adult moving away from smoking, think about your own preferences, begin modestly and consider speaking to a stop-smoking adviser or pharmacist for professional guidance. For anyone who simply wants flavour with no nicotine, the 0mg bottle needs no extra steps at all.
The right pairing makes a noticeable difference to how any shortfill tastes. The first thing to check is thickness. Liquids with more vegetable glycerine are thicker and produce denser vapour, and they work best with coils built for them, normally lower-resistance coils with wider wicking holes. Liquids with more propylene glycol are thinner, flow more freely and suit tight, low-power pod systems. Our listing does not confirm the Red Ocean Lemonade split, so read the label before you choose hardware.
If you are still shopping for a device, the vape kits collection covers refillable systems from simple pod styles to larger tank-based setups. As a rule of thumb, small refillable pod kits reward a thinner liquid and gentle draws, while sub-ohm tanks are designed for thicker liquids and bigger clouds. Matching the two is more important than the price of either.
Coils deserve attention, because they are the part that actually meets your liquid. Sweetened juices, lemonades included, tend to leave residue on the coil over time, and that residue dulls flavour well before the coil stops working. When the crisp citrus note starts to taste flat or slightly toasted, a fresh coil usually fixes it. Browse the replacement coils range once you know which device you own, and keep a spare in the drawer so a flat day does not turn into a flat week.
Power settings matter as much as hardware. Start at the low end of the range printed on your coil, then raise it a little at a time until the flavour and warmth feel right. A lemonade can taste sharper and thinner at low power and sweeter and heavier at high power, so a few small adjustments are worth your time.
As for upgrades, a second tank or pod filled with a different flavour lets you swap without emptying anything. Many regular users keep one device on a citrus lemonade and another on something softer, which stops palate fatigue creeping in and gives each coil a longer life.
Heat, light and time are the three enemies of any e-liquid, and a sensible storage routine deals with all of them. Keep the bottle upright, with the cap pushed on firmly, in a cool and dark place such as a drawer or cupboard. A sunny windowsill, a car glovebox on a warm day or a spot beside a radiator will speed up the ageing of the liquid, darken its colour and dull the flavour you paid for.
Safety comes first with any bottle on a shelf. Store it well out of reach of children and pets. Even a nicotine-free liquid is not a drink, and once you add nicotine shots the bottle becomes far more hazardous. If you do mix a stronger bottle, write the strength and the date on the label so nobody mistakes it later for the nicotine-free original. Never transfer e-liquid into drinks bottles, food containers or anything a child might recognise as something to sip.
Bottle shape matters when you are carrying it about. A large, partly filled bottle can leak if it is knocked or if pressure changes, so keep it upright inside a zip bag when travelling. Wipe the nozzle after every fill, because dried residue around the neck makes the cap harder to remove and the bottle sticky to hold.
Keep an eye on the best-before date printed on the packaging, and treat it as your guide to how long the liquid will stay at its best. When you mix in shots, give the bottle a good shake and let it rest. Some people let a freshly mixed bottle stand for a day so the contents settle together, while others use it straight away. Both approaches are fine, and the choice is purely one of habit.
Finally, deal with spills promptly. Wipe liquid from skin with a damp cloth and wash with soap and water, mop surfaces with kitchen roll, and bin the used paper where pets cannot reach it. Dispose of empty bottles in line with your local recycling rules, rinsing them first if your council asks you to.
No product suits everyone, so here is a balanced ledger rather than a sales pitch. Start with what works in this bottle's favour.
And now the drawbacks, because they matter just as much.
Weigh those two lists against how you actually vape. If you refill regularly, enjoy citrus drinks and are comfortable with a little preparation, the pros outweigh the cons by a comfortable margin. If you want a device you never have to think about, the convenience of a sealed product is probably worth more to you than the flexibility of a bottle.
One more point in fairness. Because every Caliypso flavour is priced alike, you lose very little by choosing the wrong one. The worst outcome is a bottle you leave half finished, and the best is a flavour you reorder for months. Try one, form your own view, and use that experience to pick the next.
Most problems with refillable vaping trace back to a handful of causes, and nearly all of them are easy to fix at home. Run through the list below before you assume the liquid is at fault.
Keep a small notebook or phone note of what you changed and when. Changing power, coil and liquid all at once makes it impossible to tell which one helped. If you work through the list and the problem persists, get in touch with the team through the contact page with your order number and a short description, and they can help you work out whether the fault lies with the bottle, the device or the setup.
Ordering should be the easy part, and the details are simple. Delivery is free across the UK on orders over £20, and orders placed before 4pm are dispatched the same day. The full picture, including delivery speeds, charges below the free threshold and any exceptions, sits on our shipping information page, which is the page to trust if anything here seems to differ.
Because vaping products are restricted to adults, you must be aged 18+ to buy this bottle, and age is checked as part of the buying process. The age verification page explains how that works and what to expect, so it is worth a look before you reach the checkout. Orders cannot be completed for anyone who is under age, and we cannot make exceptions.
When the parcel arrives, open it promptly and check that the bottle is the flavour you ordered, that the cap is tight and that nothing has leaked in transit. Genuine stock should arrive sealed and labelled, with the label readable enough to give you the volume, the shot headroom and the best-before date. Store the bottle upright straight away.
For returns and refunds, check the current terms on the shipping page before you order, since policies for consumable liquids can differ from those for hardware. If something arrives damaged, leaking or not as described, contact the shop promptly with your order number and clear photos, so the team can look into it properly and tell you what happens next.
If you are planning to add nicotine shots or buy a spare coil, order everything at the same time. It keeps your delivery to a single parcel and means you are not left with a half-ready setup waiting for the second package. Take a moment, too, to confirm your device accepts a refill bottle, so the delivery you are waiting for is one you can use the day it arrives.

Caliypso 100ml shortfills focus on lemonade and wave-style flavour combinations — refreshing, often summer-themed builds.
The bottle is priced at £7.99 and is supplied at 0mg, so it contains no nicotine as sold. Every flavour in the Caliypso 100ml range shares the same price and the same strength, which means you are choosing on taste alone. If you want nicotine, you add shots yourself after purchase, and the finished strength depends on how many shots fit and how much liquid the bottle holds.
No. As supplied it is a 0mg shortfill, so there is no nicotine in the bottle. The 100ml size is only possible in the UK because the liquid is nicotine-free. If you choose to add nicotine shots, the bottle then contains nicotine and should be labelled, stored and handled accordingly. Keep it away from children and pets, and never decant it into containers used for drinks.
The product listing tags it as lemonade and lemon, so expect a citrus-led profile in the style of a sweetened, slightly tart lemon drink. We do not have a manufacturer tasting breakdown that says which fruit, if any, the red in the name refers to, so we have not guessed. A sensible approach is to try the bottle for a day or two and judge it on your own palate.
Yes, the bottle has spare headroom for that purpose. Nicotine shots are 10ml bottles, commonly 18mg/ml. The label on your bottle tells you how much liquid is inside and how many shots it has space for, and that limits what you can add. Work out the strength first, add shots one at a time, shake well and mark the bottle clearly afterwards.
Any refillable device with a fill port or an open tank, such as a refillable pod system or a tank-style kit. Check the label for the VG to PG split and match it to your coil, because thicker liquids suit coils with wider wicking holes and thinner liquids suit tight, low-power pods. Always confirm your device is designed to be refilled before you order a bottle.
No. Disposable vapes are sealed and cannot be refilled, and many closed pod kits accept only pre-filled pods. Pouring liquid into a device not designed for it can damage the hardware and is not safe. If you want a device that needs no filling, look at disposables or pre-filled pod kits instead, and keep the shortfill for a refillable system.
There is no honest single figure. Puff counts apply to disposables, whereas a bottle lasts as long as your device, coil, power setting and habits allow. A light user may take a long time to finish one, while someone vaping at high power will use it much faster. Check the liquid volume on the label rather than relying on the 100ml in the product name.
Keep it upright with the cap firmly on, in a cool, dark place away from direct sunlight, radiators and hot cars. Store it well out of reach of children and pets. If you have added nicotine shots, write the new strength and the date on the bottle. Check the best-before date on the packaging, and wipe the nozzle after each fill to stop residue building up.
Delivery is free across the UK on orders over £20, and orders placed before 4pm are dispatched the same day. Charges for smaller orders and details of delivery speeds are listed on the shipping information page, which is the best place to check current terms. Remember that a nicotine-free bottle still needs an age check at the point of sale.
Yes. Vaping products are strictly for adults aged 18+, even when a bottle ships at 0mg, and age is checked as part of the buying process. The age verification page explains the steps. Please do not buy this product if you are under 18 or if you have never used nicotine and have no reason to start. Keep the bottle out of reach of children.
