Bar salts are a nicotine salt e-liquid that brings the smooth throat hit and bold, disposable-style flavors you loved to your refillable pod kit or MTL device. Since single-use disposables were banned across the UK, bar salts have become the go-to option for vapers who want that same familiar taste without breaking the law. But what exactly is a bar salt, how is it different from your typical freebase e-liquid or nicotine salt, and should you make the switch?
In this article, we’ll walk you through everything you need to know about bar salts and how they’ve become the standard way to enjoy those much-loved flavours in a fully legal, refillable format.
What Is a Bar Salt E-liquid?
“Bar salt” is a market category, not a separate legal type of nicotine or e-liquid. And, as mentioned earlier, it is a nicotine salt e-liquid produced to replicate the same high plateaus of flavour that disposable vapes used to deliver.
Bar salts aren’t wildly different from other kinds of e-liquid; they still use PG, VG, nicotine, and flavourings. But they stand out in terms of taste intensity and how smoothly they hit the throat.
Are Bar Salts and Nic Salts the Same?
Technically, bar salts and nic salts are the same. The best way to think of a bar salt is as an evolution of your favourite 10ml nic salt e-liquid.
Bar salts are made in the same way as nicotine salts, with benzoic acid used to neutralise the alkalinity of the vape juice. This results in a smoother inhale and more pronounced flavour profiles, and it also introduces nicotine to the bloodstream faster.
What differentiates bar salts from standard nic salts is the flavouring used. There was a time when freebase nicotine e-liquids with increased sweeteners and taste concentrates were referred to as “Malaysian style,” but this has since become the default approach to bar salt production.
Another notable difference is that bar salts generally offer more nicotine strengths to choose from than nicotine salts did, making it easier for vapers to reduce their nicotine intake over time while sticking with their favourite flavours.
Note that under TPD (Tobacco Products Directive) rules, nicotine-containing e-liquids in the UK are still capped at 20mg strength and sold in 10ml bottles maximum, so you won’t find bar salts outside of those limits (more on this below!)
| E-liquid Type | Flavour | Strengths | Throat Hit | Vaping Style |
|---|---|---|---|---|
| Freebase e-liquid | Muted | Wide range (3mg, 6mg, 12mg, 18mg) | Strong | MTL, DTL |
| Nicotine Salts | Pronounced | Low range (typically 10mg, 20mg) | Low | MTL |
| Bar Salts | Intense | Wide range (up to 20mg) | Low | MTL |
What Are the UK Rules on Bar Salts?
Because bar salts are, at their core, a standard nicotine salt e-liquid, they fall under exactly the same rules as any other vape juice sold in the UK. It’s worth getting familiar with these before you buy, especially with a few changes rolling out over the course of 2026.
The main set of rules comes from the Tobacco and Related Products Regulations (TRPR), which implement the TPD in the UK. These set the ground rules for every bar salt on the shelf:
- Nicotine strength is capped at 20mg/ml. No bar salt, however intense the flavour, can legally go above this.
- Bottles are capped at 10ml. This is why you’ll always see bar salts sold in small bottles rather than the larger shortfills used for freebase juice.
- Packaging must be child-resistant and tamper-evident, with clear warning labels so you know exactly what you’re buying.
- Every bar salt must be notified to and published by the MHRA before it can legally go on sale, so it’s genuinely worth sticking to established retailers and brands rather than anything unverified.
On top of TPD rules, Vaping Products Duty has applied since 1 October 2026. Bar salts made or imported in the UK from that date need a Vaping Duty Stamp on the pack, and from 1 April 2027 every vaping product sold in the UK must carry one.

What Are the Key Advantages of Bar Salts?
The most obvious advantage of bar salts is their pronounced flavour, thanks to the concentrated flavourings used. Beyond taste, bar salts also give you more nicotine strength options and, crucially, they’re the only legal way left to get that disposable-style vaping experience. Here’s a closer look at each advantage:
1. More Flavourful
Bar salts use higher concentrations of sweeteners and taste concentrates to deliver intense taste profiles, similar to those once found in disposable kits like Elf Bar and Lost Mary. This makes vaping more pleasant than ever and offers a level of satisfaction that cigarettes simply can’t match.
2. More Nicotine Strength Options
Most nic salt e-liquids were traditionally only available in 20mg, in line with TPD restrictions on nicotine levels. Some ranges also offered 10mg. This pales in comparison to the lower strengths regularly available in freebase e-liquids. Bar salts combine the best of both worlds, pairing nic salt flavour with the nicotine strength variety of freebase juice.
3. The Only Legal Route to That Disposable-Style Hit
Since single-use disposable vapes were banned from sale and supply across the UK on 1 June 2025, there’s no legal way to buy a genuine disposable anymore. If you want the flavour and throat hit that made devices like Elf Bar and Lost Mary so popular, a bar salt in a refillable pod kit is now the only compliant way to get it.
What Device Do I Need for Bar Salts?
When choosing a vape kit for bar salts, look for MTL vapes. Most bar salts are formulated with a 50 VG / 50 PG mix, resulting in a thin, runny composition, though as more refillable ranges launch post-disposable-ban, you’ll increasingly see slight variations in ratio depending on the brand and coil design.
Sub-ohm or DTL vape kits will struggle to absorb these thinner liquids and will produce more vapour than intended, without delivering the smooth throat hit bar salts are known for.
MTL kits and pod systems use small amounts of power to produce moderate vapour and are fitted with coils specifically designed to absorb thin bar-style e-liquids. If you need recommendations, check our review of the best MTL vape kits.
What Bar Salt Should I Get?
Bar salts have seen a huge rise in both popularity and production, and with disposables now off the market entirely, that demand has only grown, leaving you with a genuinely wide (and sometimes confusing) sea of options. Former disposable brands like Elf Bar and Eluxtech have shifted their focus almost entirely to refillable formats, alongside established e-liquid manufacturers like MIST, whose Bar Salts range has become a firm favourite among vapers making the switch from single-use devices.

Which Nicotine Strength Should I Choose?
With bar salts offering a wider spread of strengths than most disposables ever did, picking the right one comes down to how much you were smoking or vaping beforehand, rather than just grabbing whatever strength your old disposable happened to come in.
If you were getting through a disposable a day, or you’re coming straight from cigarettes, 20mg is usually the closest match. It’s the strongest strength permitted under TPD rules and delivers that fast, satisfying nicotine hit long-time smokers tend to look for.
If you’ve already cut down a little, or you found 20mg a touch too harsh on the throat, 10mg is worth trying. You’ll still get the same intense bar salt flavour, just with a slightly softer hit and less nicotine per puff.
Vapers who’ve been smoke-free for a while, or who simply vape more casually throughout the day, might find lower strengths (where available) suit them better.
