Caliypso Cold Surf 100ml at a Glance

Caliypso 100ml Shortfill E-Liquid Cold Surf is a nicotine-free vaping liquid priced at £7.99, supplied in a 100ml bottle and sold at 0mg. It belongs to the Caliypso range, a brand line of 37 listings that share one price and one zero-nicotine starting point. Cold Surf sits in the Surf family, next to the Black, Blue, Green, Orange, Purple, Rainbow and Red versions, and it is the one whose name points towards a cooler profile.

The first thing worth being clear about is what this product is not. It is not a device, it is not a pod, and it has no battery or coil of its own. It is a refill liquid, so you need something to put it in: a tank, a refillable pod or another open system. If you have no hardware yet, choose that first, because the bottle will not do anything on its own.

The second point is the format. "Shortfill" describes a bottle sold with less liquid than its full capacity, leaving headroom so you can add nicotine shots if you want them. Plenty of buyers never touch that headroom. They use the liquid exactly as supplied, at 0mg, and treat the spare space as a quirk of the packaging. Others want a low or medium nicotine strength and use the space to mix their own. Both routes are common, and both are covered below.

This guide is organised so you can jump to whatever you need. We start with how the format works, then look at what the name does and does not tell you about taste, then the numbers, the mixing method, strength choices, hardware pairing, coil care, storage, an honest list of strengths and limitations, troubleshooting, and finally delivery and age checks. You do not have to read it in order.

One legal note before we go further. You must be 18 or over to buy from this shop, and if you add nicotine to the bottle, remember that nicotine is addictive. Keep every bottle, with or without nicotine, out of reach of children and pets.

How Shortfill Works and Why the Bottle Has Spare Room

UK rules cap nicotine-containing e-liquid at ten millilitres per bottle. Nicotine-free liquid is not held to that limit, which is the only reason a 100ml bottle of flavoured liquid can be sold at all. Shortfills grew up inside that gap. A manufacturer fills a large bottle with flavoured liquid at 0mg, deliberately leaves some air space, and sells small nicotine shots separately. You then decide at home whether to combine them.

That arrangement explains the mixing guide printed on the label. The bottle is not defective or underfilled in any unfair sense; the space is there on purpose. A standard shot is a 10ml bottle of nicotine in a neutral base, and the label tells you how many of those the bottle can accept before it is full. Exceed that number and you will be left with a bottle that cannot be closed properly, which is a recipe for leaks.

It helps to see where shortfill sits alongside other liquid types. A shortfill e-liquid is a large-volume bottle that usually starts at 0mg. A nicotine salt bottle is a small 10ml container that already contains nicotine and is made for lower-powered devices. A nicotine-free e-liquid can be either a shortfill or a smaller bottle, and it is the simplest option if you want flavour with no nicotine at all. This shop lists 368 products in the shortfill category alone, so Caliypso is one choice among many rather than the only route in.

Two other UK rules shape what you can do with the liquid once it arrives. First, nicotine strength for sold products is capped at 20mg per millilitre. Second, tanks and pods are limited to a 2ml capacity. Neither rule stops you using a large bottle. It simply means you refill your device in small amounts and keep the main bottle capped between top-ups, which is better for flavour and tidier on the desk anyway.

In short, a shortfill is a flexible, high-volume format. It rewards people who like to refill, are comfortable with a small amount of measuring, and want a lower cost per millilitre than a string of little bottles would allow.

Reading the Cold Surf Name Without Guessing

A name is a clue, not a recipe. Here is the honest position on Cold Surf: the listing gives us the name, the price, the strength and the format, but it does not publish a tasting breakdown, and we are not going to invent one. If you want the maker's own description of what is in the bottle, the artwork and label on the bottle you receive are the authority.

What the name does suggest is a cooling profile. Caliypso organises its flavours into families, and the word "cold" appears in two of them. Cold Surf is in the Surf group of eight flavours, and there is a matching Cold Wave in the Wave group of ten. The Ocean Lemonade group of ten adds Iceberg Ocean Lemonade, which also hints at a chilled finish, and there are eight standalone lemonades whose names spell out the fruit. If you like the idea of Cold Surf but are not sure about the Surf naming, comparing it with Cold Wave on the Caliypso collection page is the quickest way to see how the two relate.

How a cooling liquid behaves in your device is a different question from what it tastes of. Temperature changes perception. Warm vapour tends to feel softer and sweeter, while cooler vapour feels crisper. For that reason, many people who enjoy cold profiles run them at modest power and let the airflow do some of the work, rather than pushing the wattage up and flattening the effect. If you want a stronger cooling sensation, a tighter airflow setting and a slightly lower wattage are the first things to try.

It is also worth remembering that large-volume shortfills are usually built to be rounded rather than sharp. A thicker base smooths the edges of a recipe, so if you are used to small-bottle liquids you may find the delivery gentler than expected. That is not a flaw; it is a property of the format.

Give any new bottle a few sessions in a clean tank before you judge it. Leftover residue from a previous liquid can mask or twist the taste, and a fresh coil often tells you far more than a worn one.

The Numbers on This Listing

Let us put the verifiable details in one place. Cold Surf costs £7.99, comes in a 100ml bottle, is supplied at 0mg, and is a shortfill. Every Caliypso flavour carries the same price, so nothing about the cold profile adds a premium. Divide £7.99 by 100 and you get just under 8p per millilitre, which is the clearest single figure for comparing it with smaller bottles.

Multibuy maths is simple because the price is flat. Two bottles cost £15.98 and three cost £23.97. A third bottle matters for another reason too: this shop offers free UK delivery on orders over £20, and three bottles clear that line comfortably while two do not. If you are planning to stock up on more than one flavour from the range, that is worth keeping in mind before you check out.

There are also numbers the listing does not publish, and we would rather say so than guess. The VG/PG ratio is not stated here, nor is the exact volume of liquid inside the bottle, because 100ml describes the bottle and the label states precisely how much liquid it holds and how many shots it can take. Check those figures on the bottle itself when it arrives. They decide how thick the liquid is, which devices suit it best, and what final strength you will get if you add nicotine.

Turn volume into time and the numbers become more useful. A light user getting through around two millilitres a day would take about fifty days to finish a full 100ml. At four millilitres a day the same bottle lasts about twenty-five days, and a heavier sub-ohm user at ten millilitres a day would be through it in ten. Adding nicotine shots increases the total volume slightly, so a mixed bottle lasts a little longer than one used at 0mg.

Finally, glance at the batch code and best-before date when you unpack. They are printed on UK bottles and are the first things our team will ask for if you ever need to get in touch about a problem.

Mixing Nicotine Shots Step by Step

If you plan to use Cold Surf at 0mg, skip this section entirely. If you want some nicotine in the mix, the process is straightforward, but it rewards a little care. Work at a clear table, wash your hands, and keep children and pets well away while you do it.

• Read the label first. Find the line that tells you how many 10ml shots the bottle can take. Do not exceed it.
• Check the shot strength. Shots commonly come as 18mg per millilitre, and the figure is printed on the bottle. Your final strength depends on it.
• Open the main bottle. Remove the cap and, if it has one, the nozzle insert, so you can see the headroom.
• Add the shot. Squeeze the nicotine shot slowly into the bottle. Pouring too fast can splash and make a mess.
• Close it tightly. Replace the nozzle and cap, making sure both are firmly seated.
• Shake for about a minute. The shot is thicker than you might expect, and it needs time to blend through the liquid.
• Rest the bottle. Leave it upright for a few hours or overnight so any air bubbles settle and the mix evens out.
• Label it. Write the date and the final strength on the bottle, because you will not remember in three weeks.

A few practical notes help. Wipe up any spill straight away, because nicotine liquid on skin is best washed off promptly with soap and water. Never keep a nicotine mix in a bottle without a child-resistant closure, and do not reuse an old bottle that previously held something else. If you only want to use part of the bottle, you can pour off a measured quantity first and add a proportionally smaller amount of nicotine, but that needs careful arithmetic and is easiest to get right when you work with whole bottles and whole shots.

Once mixed, treat the bottle like any nicotine product: cap on, upright, out of sight and out of reach. If your label has any extra instructions, follow them over general advice, because the manufacturer knows its own recipe.

A Strength Guide for Cold Surf Mixes

Choosing a strength starts with a simple question: do you want nicotine at all? If you do not currently use nicotine, there is no reason to add any. Cold Surf at 0mg is a complete product as sold, and it is aimed at adults who want flavour from a liquid with nothing extra in it.

For those who do want nicotine, the arithmetic is easy once you know the formula. Multiply the shot volume by its strength to get the total milligrams of nicotine, then divide by the total volume of the finished mix. As an illustration only, suppose a bottle holds 70ml of liquid and you add one 10ml shot at 18mg per millilitre. That is 180mg of nicotine in 80ml, which comes to 2.25mg per millilitre. Add a second shot to the same liquid and you have 360mg in 90ml, which is 4mg per millilitre. Your own figures will depend on what the label says, but the method does not change.

It helps to match strength to the type of device and the way you use it. Low strengths of a few milligrams usually pair with open-airflow tanks and larger clouds, where each puff delivers a lot of vapour. Higher strengths are normally found in small, tight-airflow devices, and for those a nicotine salt product is often the more natural choice. If that is what you need, browse the nicotine salt e-liquids instead; they are designed for lower-wattage pod systems and come in smaller bottles.

If you are unsure, start low and adjust. It is much easier to add a shot to an existing bottle than to take nicotine out. Many people find that a first mix feels either obviously too weak or obviously too strong, and the second mix gets close to right. Keep a note of what you tried so you can repeat or refine it.

Whatever you choose, remember the cap: UK rules limit sold nicotine strength to 20mg per millilitre, and anything you mix at home should stay well inside the range you are comfortable with. Nicotine is addictive, and 0mg remains a perfectly good place to stay.

Devices That Suit a Shortfill Like This

Pairing the liquid with the right hardware is where most of the enjoyment is decided. A 100ml shortfill is made for open systems, meaning devices you refill yourself. Sealed disposables and pre-filled closed pods cannot take it, and trying to force liquid into a device not built for it will damage the hardware and could be unsafe.

The wide category of vape kits includes plenty of refillable options, from simple starter tanks to larger sub-ohm setups. If you are new to this style of vaping, look for a kit with a clearly marked fill port and a simple airflow control. If you already own a tank, check what coil heads it takes and whether the wattage range suits a thicker liquid.

For smaller, pocketable setups, refillable vape pods are the usual choice. These take a few millilitres at a time, so you will be filling often, but they are easy to carry. One thing to check is the coil resistance. Higher-resistance coils tend to prefer thinner liquid, while lower-resistance coils cope better with thicker blends. Because this listing does not publish the VG/PG split, read the label before you decide, and if your device manual recommends a particular ratio, follow that.

Fill size matters for convenience. Most shortfill bottles have a slim nozzle intended for tank and pod fill ports, but you should confirm it fits your particular device before you start. If the nozzle is too wide, use a small pipette or syringe rather than forcing it, and never overfill past the marked line.

If you tend to vape on the move, consider decanting a small amount into a travel bottle with a similar nozzle. That keeps the big bottle at home, which is better for storage, and means you are not carrying 100ml of liquid in a jacket pocket. When flavour is the priority, an open-airflow tank with a fresh coil usually shows a cold profile at its best, while a smaller pod will give you something more discreet.

Coils, Priming and Wattage for Best Results

Coils are the consumable part of any refillable device, and they have more influence on how Cold Surf tastes than most people expect. A fresh coil with cotton that has been properly soaked will give a cleaner, brighter flavour than a tired one. If you are heading into a first session with this bottle, it is worth checking that your coil is relatively new. Our coils collection carries replacements for a wide range of tanks and pods, so match the model name printed on your device rather than guessing.

Priming is the step that stops most dry hits. When you install a new coil, drip a little liquid directly onto the exposed cotton through the side holes, then fill the tank or pod and wait. Five to ten minutes is a sensible minimum. Thicker liquids need more time to wick through the cotton, so do not rush. Firing a coil before it is saturated scorches the cotton and can leave a burnt taste that never fully clears.

Start your wattage at the low end of the range printed on the coil. Raise it in small steps until the vapour feels right. With a cold profile, many people find the sweet spot is below the middle of the range, because high power warms the vapour and reduces the cooling effect. If the flavour feels thin, try tightening the airflow before you increase the power. If it feels harsh, drop the wattage a notch.

Coil lifespan varies with how you vape, your wattage, and the liquid itself. Sweeter liquids tend to leave more residue, so you may notice flavour fading earlier than with a drier recipe. Signs that it is time for a new coil include a muted taste, a burnt edge, gurgling that was not there before, and a dark, crusty look on the cotton. Replacing the coil is cheaper than blaming the liquid.

When you change coil, rinse the tank in warm water, dry it fully, and refill. A clean start is the easiest way to get a fair read on any flavour.

Storing the Bottle and Keeping Flavour Steady

A 100ml bottle will stay with you for weeks, so how you store it matters. The aim is simple: keep the liquid away from heat, light and air, and keep it out of reach of children and pets.

Heat is the main enemy. Leave a bottle on a sunny windowsill or in a parked car and the liquid can darken, thin out and lose the fresh character it had on day one. A cupboard, drawer or shelf away from radiators is ideal. Light is the second concern, especially strong sunlight, which is why most e-liquid comes in tinted or opaque bottles. If yours is translucent, an extra layer such as the cardboard box it arrived in helps.

Air matters because oxygen slowly changes the liquid over time. Keep the cap tightly closed between uses, and avoid leaving the nozzle open while you fill your device. If you are decanting into a smaller bottle for daily use, fill that to a sensible level and return the main bottle to storage right away.

Store the bottle upright. A bottle lying on its side can seep around the cap, and a large one is heavy enough to press liquid into the seal. Upright also reduces the chance of spills if the bottle gets knocked.

If you mix nicotine into the bottle, make sure it has a child-resistant closure and label the contents clearly. Do not store a mixed bottle in a fridge or anywhere used for food. Fridges bring their own condensation problems and make accidents more likely.

As for shelf life, check the best-before date on the label. Once opened or mixed, many people aim to finish the bottle within a few months, because flavour can drift and the liquid can darken with time. A change in colour is not necessarily a problem, but if the smell or taste seems off, retire the bottle and open a fresh one.

Finally, wipe the nozzle with a dry tissue after each fill. Residue on the threads is what usually causes sticky caps and slow leaks.

Strengths and Limitations, Honestly Compared

No product suits everybody, and a fair assessment is more use than a sales pitch. Here is where Caliypso Cold Surf does well, and where it does not.

What works in its favour

• Cost per millilitre. At £7.99 for 100ml, it comes in just under 8p per millilitre, which is hard to match with small bottles.
• Flexible strength. You can use it at 0mg or add shots to reach a strength that suits you.
• One price across the range. Every Caliypso flavour costs the same, so choosing between them is purely about taste.
• A clear naming system. The Surf, Wave and Ocean Lemonade families make it easy to browse similar options.
• Plenty of volume. A single bottle goes a long way, which cuts down on repeat orders.

What counts against it

• Not portable. A 100ml bottle is a home supply, not something to carry around.
• Needs an open device. It will not work in disposables or sealed pods.
• Mixing takes effort. If you want nicotine, you need to buy shots separately and measure carefully.
• Information gaps. The listing does not publish the VG/PG ratio, exact fill volume or a tasting breakdown, so you need to read the label.
• Flavour fatigue. Living with one flavour for weeks can get dull for some people, especially with a profile as distinctive as a cold one.

If you like the sound of the range but want to hedge, buy a single bottle first rather than a stack. If Cold Surf is not quite what you hoped for, the rest of the Caliypso range offers dozens of alternatives at the same price, including Cold Wave and the other Surf colours, and they all follow the same mixing method.

For people who want convenience over cost, a disposable or pre-filled pod will generally suit better. For people who enjoy tinkering with devices and strengths, shortfill is a very natural fit.

Fixing Leaks, Dry Hits and Muted Flavour

Something not right with your vape? Start with the simplest cause, because most problems come down to a handful of habits rather than a faulty bottle.

Leaking from the device. Overfilling is the usual culprit. Fill only to the marked line, leave a little air space, and close the fill port firmly. Check that the coil is seated correctly, that the seals are in place, and that nothing is cracked. Changes in air pressure, such as on a flight, can also push liquid out, so keep the device upright and the tank less than full when travelling.

Leaking from the bottle. If the cap is sticky or the nozzle drips, wipe the threads and make sure the tamper ring was removed cleanly. A bottle stored on its side or in a warm place is more likely to seep.

Dry or burnt hits. The classic cause is a coil that has not been primed, or one that is wearing out. Remove the tank, add a few drops directly to the cotton, wait, and try again at a lower wattage. If the burnt taste persists, replace the coil. Also check that the liquid level has not dropped below the wicking holes.

Muted flavour. A tired coil, a dirty tank or chain vaping are the most common reasons. Give the device a rest between sessions, clean the tank, and try a fresh coil. If the flavour is still weak after that, drop the wattage slightly and tighten the airflow.

Gurgling or spitting. This usually points to too much liquid in the coil chamber or an airflow setting that is too tight. Open the airflow a touch, and clear the chamber with a few dry puffs without firing the coil.

Mix feels too strong or too weak. If you have added nicotine and it does not feel right, adjust the next batch rather than topping up the current one. Keep notes so you can repeat what works.

Delivery, Age Checks and Returns in Brief

Finally, the practical side of buying. Orders placed before 4pm are dispatched the same day, and UK delivery is free on orders over £20. Our shipping page sets out the delivery options, timescales and costs in full, so check it if you need a specific service or are sending somewhere unusual. When the parcel arrives, check that the cap seal and tamper ring on the bottle are intact before you open it.

Everything we stock is 100% genuine and carries the standard warnings required by law. That includes the age restriction: vaping products can only be sold to adults aged 18 or over. When you place an order you may be asked to confirm your age, and the courier may ask to see ID on delivery. Our age verification page explains what to expect, so it is worth reading if you have not bought from us before. Please do not order on behalf of anyone under 18; it is illegal.

On value, remember that every Caliypso flavour costs £7.99. If you are tempted to try Cold Surf alongside another flavour, two bottles come to £15.98 and three to £23.97, which pushes you over the free delivery threshold. Browsing the vape deals page is a good idea before you finalise a basket, as offers change and may cover other items you need, such as coils or nicotine shots.

If something goes wrong with an order, such as damage in transit or a wrong item, contact our team as soon as possible with your order number and a photo if relevant. The sooner we hear about it, the sooner it can be put right. Keep the batch code and best-before date from the bottle to hand, as they help us trace any issue quickly.

If Cold Surf sounds like what you were hoping for, pick up a bottle and enjoy it responsibly.
