Double Brew Caramel Frappe Nic Salt 10ml 20mg at a Glance

Double Brew Nic Salts Caramel Frappe is a 10ml bottle of nicotine salt e-liquid at 20mg/ml, made for refillable pod kits and other low-power mouth-to-lung devices. The flavour idea is an iced coffee drink: a cold-brew style coffee base, a ribbon of caramel syrup and a soft, milky finish that echoes the whipped top on a coffee-shop frappe. If you want a dessert-leaning vape that tastes like a sweet coffee rather than fruit or menthol, this is the type of liquid that fills that gap.

This page covers the practical questions a UK buyer usually has before ordering. What does 20mg/ml feel like when you inhale it? Which devices suit it? How long will a 10ml bottle last? What goes wrong when people use it badly, and how does it compare with other coffee and caramel nic salts? We have written it as a plain explainer rather than a sales pitch, so you will also find the situations where this is not the right product for you.

A few basics before the detail:

• Format: a 10ml bottle of nic salt e-liquid, which is the largest bottle size UK rules allow for nicotine-containing liquid.
• Strength: 20mg/ml, equal to 2% nicotine and the highest strength that can legally be sold in the UK.
• Flavour: Caramel Frappe, an iced coffee and caramel dessert profile.
• Suited to: refillable pod systems and low-wattage mouth-to-lung (MTL) devices.
• Age restriction: sold to adults aged 18 or over only, and intended for people who already smoke or vape.

One point of context matters here. Single-use disposable vapes can no longer be sold in Great Britain, so a refillable kit plus a bottle of nic salt is now the standard route for anyone who liked the simplicity of a disposable. That is the job this bottle does: it gives you a ready-mixed, high-strength liquid that works in the small pod devices most people already own.

Specifications and What They Mean in Practice

Specification lists are only useful if you know what each line means for your day-to-day vaping. Here is how the numbers on this bottle translate into real behaviour.

• Volume, 10ml: enough to fill a typical 2ml pod roughly four to five times, depending on how much you waste to priming and spills. It is also the legal ceiling for a bottle of nicotine e-liquid in the UK.
• Nicotine, 20mg/ml: the legal maximum. In a 10ml bottle that is 200mg of nicotine in total, which is why the bottle must carry the nicotine warning and why it needs child-resistant, tamper-evident packaging.
• Nicotine type, nic salt: nicotine salts are made by combining nicotine with an acid so the liquid has a lower pH than freebase nicotine. The practical effect is a smoother throat hit at high strength, and a faster, more cigarette-like nicotine delivery.
• Intended device class: low-power MTL kits, usually between roughly 6W and 15W, with coils around 0.8 to 1.6 ohm.
• VG/PG ratio: nic salt liquids are normally balanced or PG-leaning so they wick quickly in small pods. Check the label on your bottle for the exact split, because we would rather you read the printed figure than rely on a general rule.

We do not list a puff count for a bottle in the way a disposable does, because the number depends on the device, your wattage and how long you draw. As a planning guide only, a 10ml bottle used in a low-power pod kit commonly gives somewhere in the region of 1,000 to 2,500 puffs. A light user taking short, gentle draws will sit towards the top of that range; someone taking long, warm draws at higher wattage will burn through it faster.

The takeaway is simple: this is a high-strength liquid for small, low-power devices. Every spec on the bottle points the same way, and ignoring that pairing is the most common cause of a bad experience.

Vapour and Throat Hit: Performance and Puff Delivery

At 20mg/ml in a nic salt formulation, the throat hit is firmer than a low-strength freebase liquid but noticeably smoother than the same strength in freebase nicotine. Most people describe it as a gentle tap at the back of the throat on the first draw, followed by a rounded, warm sensation in the chest. That profile is deliberate: nic salts were developed so smokers moving to vaping could take a satisfying dose of nicotine without a harsh, scratchy hit.

Vapour volume is modest. Because this liquid is built for small coils at low wattage, you should expect a light, tight cloud rather than a big plume. That suits a dessert-style flavour, because the aim is taste and nicotine delivery rather than cloud size. If you are used to sub-ohm devices that produce thick vapour, the difference will be obvious, and you may initially feel it is understated. Give it a few days; many people find the lower volume is more discreet and easier on the throat over a full day.

Puff delivery is consistent from the first fill to the last as long as the coil is healthy. Typical behaviour looks like this:

• First few puffs after filling: slightly muted flavour while the cotton or mesh finishes soaking. Waiting a few minutes avoids this.
• Mid-tank: the most even flavour and throat hit, with the coil fully wicked.
• Low in the pod: if the liquid level drops under the wicking holes, you may get a hot, slightly burnt taste. Refill before you reach that point.

Nicotine absorption with nic salts is quick, which is the reason many smokers find them more satisfying than low-strength freebase. It is also the reason 20mg/ml is easy to overdo. Take a few draws and pause. If you feel lightheaded, nauseous or jittery, you are taking in more nicotine than you need, and a lower-strength bottle would suit you better.

Flavour Profile: What Caramel Frappe Tastes Like

A frappe is an iced, blended coffee drink, and the flavour concept follows that closely. A useful way to think about the profile is in three layers, each arriving at a slightly different point in the draw.

• Inhale: a cool-style, slightly roasted coffee note leads. It reads as cold brew rather than hot espresso, with a touch of bitterness that stops the sweetness feeling flat.
• Mid-draw: caramel comes through as a buttery, toffee-like sweetness. It is the dominant sweet note, closer to a syrup drizzle than to burnt sugar.
• Exhale: a soft, creamy finish that suggests milk and whipped cream. It rounds off the edges of the coffee and leaves a lingering sweet aftertaste.

Two honest caveats. First, the word frappe suggests cold, but a cold sensation in e-liquid usually comes from a cooling agent such as menthol or a synthetic coolant. Do not assume this bottle is icy on the throat; the chill described here is mostly a flavour impression, the way a cold coffee smells and tastes cooler even when it is not. If the label lists no cooling additive, expect a neutral-temperature vapour with a cold-coffee character. Second, flavour is subjective. Coffee notes in e-liquid can taste more like roasted malt or chocolate to some palates, and caramel can read as vanilla or butterscotch.

How sweet is it? Sweeter than a plain coffee tobacco-style blend, less sweet than a candy or fizzy-drink flavour. Because caramel and cream flavourings are thicker than fruit essences, they tend to leave a faint film on the coil over time. That does not make the liquid poor quality; it simply means dessert and coffee profiles benefit from sensible coil changes, which we cover in the troubleshooting section.

If you vape through the day, this flavour works well as an after-meal or morning-coffee companion. If you prefer a sharp, juicy vape in the afternoon, you might alternate it with a fruit or menthol bottle. Flavour fatigue is real with sweet liquids, and having a second option on hand helps.

Bottle Design, Packaging and Build Quality

The 10ml format is a plastic bottle with a fine nozzle, which is the standard layout for nic salts in the UK. The nozzle is narrow on purpose: refillable pods have small fill ports, and a thin tip lets you place liquid exactly where it belongs without flooding the airflow channel.

Look for these features when your bottle arrives:

• Child-resistant cap: required for nicotine liquid in the UK. You usually press down and twist, or squeeze and turn. If you struggle with it, ask an adult without grip problems to open it rather than forcing it, because a cracked cap will leak.
• Tamper-evident seal: a ring or seal that shows the bottle has not been opened. If the ring is already broken, contact us before using it.
• Printed warnings and ingredients: the nicotine warning, batch information and ingredient list are legally required on the pack. Read these on your own bottle; they are the authoritative source for what is inside.
• Tactile quality: the plastic should feel firm with a slight give, so you can squeeze out liquid without it spurting. Soft, floppy bottles tend to over-dispense.

Storage matters more than most people think. Keep the bottle upright, in a cool, dark place, away from direct sunlight, radiators and car dashboards. Heat and light degrade flavour and darken the liquid over time. A slightly darker colour in a coffee and caramel liquid is normal because the flavourings naturally tint with age, but a sudden change in smell or taste is a reason to stop using it.

Always store nicotine liquid out of reach of children and pets. A 10ml bottle at 20mg/ml contains a significant total amount of nicotine, and the sweet dessert smell makes it more appealing to a curious child or animal than a tobacco flavour would be. Keep it in the original packaging or a locked drawer rather than loose in a bag.

Battery and Charging: Choosing the Right Device for This Liquid

A bottle of e-liquid does not have a battery, so this section is about the device you pair with it. Getting that pairing right affects flavour, coil life and how often you charge.

Pod kits that suit 20mg nic salts typically have a battery between about 400mAh and 1,000mAh. The numbers have practical effects:

• Around 400 to 600mAh: pocketable and light, suited to lighter use. Expect to charge daily if you vape regularly.
• Around 700 to 1,000mAh: a better match for all-day vaping with a 20mg salt, and often enough for a full day plus a margin.
• Output range: most suitable kits operate at a fixed or adjustable power somewhere between 6W and 15W. Nic salts tend to work well at the lower end.

Charging tips that apply to nearly every pod device:

• Use a USB-C or the cable supplied with the kit, and a normal 5V phone-style adapter or computer port. Fast chargers designed for laptops are not needed.
• Do not charge unattended overnight on a soft surface such as a bed or sofa.
• If the battery gets noticeably hot, unplug it and let it cool.
• Avoid leaving a device in a hot car or a coat pocket against keys and coins.

Battery level also changes how this liquid tastes. When a device is low on charge, voltage sag means the coil heats less evenly, and a creamy coffee profile can taste thinner and more bitter. If flavour seems to fade late in the day, charge the device before blaming the e-liquid.

At end of life, never put a vape battery in household waste or standard recycling. Lithium batteries can cause fires in bin lorries and recycling plants. Take the whole device to a drop-off point for waste electricals, such as the collection boxes in many supermarkets, or a council recycling centre. Many retailers that sell vapes are also required to take back old devices.

Coil and Mesh Technology: What Suits 20mg Salts

The coil is where the liquid becomes vapour, and the right coil type makes a measurable difference to how a coffee and caramel liquid tastes. The kit you pick decides the coil, so here is how to choose one.

• Standard wire coils (0.8 to 1.2 ohm): the usual choice for MTL pod kits. They heat quickly, deliver a firm throat hit and work well with nic salts at 6W to 12W.
• Mesh coils: a flat mesh surface gives more even heating and often a fuller flavour. They can sometimes run hotter if you push the power, so keep wattage modest with sweet liquids.
• Ceramic coils: porous ceramic wicks resist burnt tastes and tend to last well, though some vapers find the flavour slightly softer.
• Sub-ohm coils (below 0.5 ohm): not suitable. They are built for high power and low-strength liquid. Using 20mg nic salt in one delivers an excessive amount of nicotine and a harsh hit.

Coil resistance guides power. A higher resistance of 1.0 to 1.6 ohm with a nic salt is a sensible baseline. If your device lets you choose wattage, start low, then adjust upward in small steps until the flavour is full without getting hot.

Caramel and cream flavourings contain sugars and fats that can caramelise on the coil, building a dark residue known as gunk. This is the main reason dessert liquids shorten coil life. As a rough guide, expect a coil to last somewhere between one and three weeks with regular use, and closer to the lower figure with a sweet flavour like this one. Signs it is time to replace:

• The flavour turns flat, muddy or faintly burnt even with a full pod.
• You get a dry or scratchy throat hit.
• Gurgling or spitting increases.

Never keep chain-vaping on a failing coil. A burnt coil produces unpleasant vapour and wastes liquid. Swap it, prime the new one properly and the flavour will return.

Nicotine Strength Guidance: Is 20mg/ml Right for You?

Choosing the correct nicotine strength is the most important decision on this page. Too low and you will keep reaching for a cigarette; too high and you will feel unwell. A bottle of 20mg/ml is the strongest legally available in the UK, and it is aimed squarely at people who currently smoke.

A rough starting guide used by many stop-smoking services:

• Heavier smokers: around 10 or more cigarettes a day, or someone who smokes within 30 minutes of waking, often start on the highest nic salt strength.
• Moderate smokers: around 5 to 10 cigarettes a day may do better on a mid-range strength such as 10mg/ml, moving down further over time.
• Social or very light smokers: usually need only a low strength, and do not need 20mg/ml.

This is general information, not medical advice. If you want to stop smoking, speak to your local stop-smoking service, pharmacist or GP. Many areas offer free support and can talk you through vaping as a quitting aid.

Signs that 20mg/ml is too strong for you:

• Dizziness, sweating or nausea after a few puffs.
• A racing heart or restless feeling.
• A harsh hit that makes you cough.

If you notice these, stop, drink some water and consider a lower strength. Signs it is too weak are the opposite: cravings return within an hour, you vape constantly and still feel unsatisfied. Remember that nic salts deliver nicotine efficiently, so you generally need fewer puffs than with freebase at the same strength.

Finally, do not use this bottle if you have never smoked or vaped. Nicotine is addictive, and a 20mg salt is far more than a non-smoker needs. It is also not suitable for use by anyone under 18, and anyone who is pregnant, has a heart condition or takes regular medication should seek medical advice first.

Who Caramel Frappe Is For, and Who Should Skip It

No flavour suits everyone, and being upfront about fit saves you money. Here is a practical breakdown.

This is likely a good match if you:

• Currently smoke around 10 or more cigarettes a day and want a high-strength, smooth alternative.
• Enjoy sweet coffee drinks, caramel lattes or frappes and want a similar taste in a vape.
• Use a refillable low-power pod kit or MTL device and want a 10ml refill.
• Prefer a flavour that is more dessert than fruit, without a strong menthol chill.
• Are moving from a disposable vape and want a refillable setup that gives similar convenience.

You may want to skip it if you:

• Have never smoked or vaped. Nicotine at 20mg/ml is not for non-smokers.
• Use a sub-ohm tank or high-wattage mod. The wrong device pairing leads to harsh, excessive nicotine intake.
• Dislike coffee or find creamy flavours cloying. A fruit or menthol bottle will suit you better.
• Are sensitive to nicotine or typically smoke fewer than five cigarettes a day. A lower strength is the sensible choice.
• Want large clouds. This product is designed for tight, flavour-led draws.

There is a middle group worth mentioning: vapers who already use a lower-strength liquid and find it unsatisfying. For them, 20mg salt can be a step up, but we recommend trying 10mg or 12mg first if you are unsure, and only moving to 20mg if cravings persist.

Lastly, think about the occasion. A creamy coffee flavour often suits certain times of day, for example with a morning coffee or after dinner. If you need a flavour that stays fresh through a long shift, you might prefer something lighter. Buying one bottle first, rather than a multipack, is a low-risk way to find out.

How to Fill and Use Double Brew Caramel Frappe

Filling a pod takes a minute once you know the steps, and doing it carefully prevents most leaks and burnt hits. Follow this routine.

• 1. Check the device: make sure it is switched off and not charging. Wipe the fill port clean.
• 2. Open the bottle safely: press and twist the child-resistant cap, keeping the bottle upright so liquid does not spill.
• 3. Open the pod's fill port: pull back the silicone plug or slide the cover, depending on your kit.
• 4. Fill slowly: aim the nozzle at the side wall of the fill hole, not straight at the centre post, and squeeze gently. Stop when the liquid is just below the max line. Do not cover the airflow channel.
• 5. Close the port: push the plug fully home. A loose plug is a common cause of leaks.
• 6. Let it sit: wait five to ten minutes so the wick soaks up liquid. This is the single biggest factor in avoiding dry hits.
• 7. Take gentle first puffs: two or three short draws without firing for long, then settle into your normal rhythm.

For a brand new coil, prime it before use: put a few drops straight onto the exposed wick if your pod design allows, then fill as above and wait the full ten minutes. Priming a fresh coil is the simplest way to avoid a burnt taste on day one.

Use tips for everyday vaping:

• Take slow, steady mouth-to-lung puffs of two to three seconds, then pause. Chain vaping overheats the coil and hides flavour.
• Refill when the pod is about a quarter full, not when it is empty.
• If you switch flavours, rinse the pod in warm water, dry it fully, then refill. Coffee and caramel tones linger and can colour the next liquid.
• Wipe the mouthpiece regularly to prevent sticky residue.

Keep it simple: low power, short draws, fill early, let it soak. That routine gets you the flavour the liquid is designed to deliver.

Troubleshooting: Common Problems and How to Fix Them

Most problems with nic salts are about setup rather than the liquid. Use this checklist before assuming the bottle is faulty.

• Burnt or acrid taste: usually a dry coil or a tired one. Refill, wait ten minutes, take shorter puffs. If it persists, replace the coil.
• Weak or muted flavour: check the battery level, because low charge can thin out flavour. Also consider whether you have been vaping the same sweet flavour for days; taste fatigue is common. Rinse your mouth with water, or swap to a different bottle for a day.
• Leaking from the pod: a loose fill plug, overfilling, or a cracked pod. Refill to just below max, press the plug firmly, and keep the device upright when not in use.
• Gurgling or spitting: too much condensation or a flooded coil. Blow through the mouthpiece gently to clear the airflow, wipe excess liquid, and lower the power if adjustable.
• Harsh throat hit: the wattage may be too high, or the strength is too much for you. Lower the power or try a lower nicotine bottle.
• Dizziness or nausea: you are taking in too much nicotine. Stop, sit down, drink water and use a lower strength next time.
• Liquid looks darker than before: mild darkening is normal for coffee and caramel flavourings as they age. If there is a sharp chemical smell or sediment, do not use it.
• Device will not fire: check the coil is seated properly, clean the contacts with a dry cotton bud, and ensure the battery is charged.

When to stop using the product: if you notice an unusual smell, a change in consistency, any sign of mould or particles, or a reaction such as a rash, swelling or breathing difficulty, stop immediately. Contact a medical professional for symptoms, and let us know about any product quality issue so we can investigate with the batch number from the bottle.

A final note on disposal. Empty bottles can go in household plastic recycling in many council areas, but check your local rules and rinse them first where required. Used pods and coils generally count as electrical or mixed waste; do not put them in the standard bin if your area offers a vape or small-electrical recycling point.

Value for Money and How It Compares With Other 10ml Nic Salts

Value comes down to what you pay per millilitre, how long a bottle lasts and how often you replace consumables. A 10ml nic salt bottle is typically priced in the low single-digit pounds, with the exact price shown on this page at the time you order. Prices change with promotions, so check the current listing rather than relying on an old figure.

Compared with a disposable, a refillable setup usually works out cheaper over a month. A disposable has a fixed number of puffs and is thrown away with its battery. With a refill bottle you pay once for the kit, then only for liquid and the occasional coil. Because single-use disposables are no longer sold in Great Britain, the real comparison is now between pod kits and prefilled pod systems. Prefilled pods cost more per millilitre, while bottles like this one cost less, though you take on the small job of filling.

How it compares in the wider nic salt market, fairly stated:

• Against other coffee and caramel salts: flavour balance differs between brands. This bottle leans towards cold coffee and caramel with a creamy finish. If you prefer a milkier, latte-style cup, a latte-labelled liquid such as Ohm Brew Caramel Latte may suit you better; the frappe concept tends to read colder and sweeter.
• Against fruit and menthol salts: dessert and coffee flavours tend to cost you slightly more in coil wear, because sugars and fats leave more residue. Fruit and menthol profiles are usually cleaner on the coil.
• Against premium boutique salts: some specialist brands charge more for hand-blended flavours and elaborate packaging. A mainstream 10ml salt like this one competes on price and availability rather than on novelty.
• Against freebase liquids: freebase is fine for sub-ohm and higher power, but at 20mg it is rougher. Nic salt is the sensible format for small pod kits.

Where it is weaker: a 10ml bottle runs out faster than a larger freebase shortfill if you vape heavily, and the 20mg strength is not for everyone. If you are a very high-volume vaper, the cost of lots of 10ml bottles can add up, and you may want to look at your overall setup.

Our honest view: if you are an adult smoker who likes coffee and caramel flavours and already owns a low-power pod kit, this is a reasonable, fairly priced refill. Treat it as one option among many, and try a single bottle before committing to a stack.
