Some FAQs About Our Vape Juice

Longfill vs Shortfill: What’s The Difference?

Most people know shortfills – bottles of nicotine-free e-liquid with space for a nicotine shot. For example, a 60ml shortfill usually comes with 50ml of juice, leaving room for 10ml of nic shot.

Our Bar Salt Longfills work differently. Each bottle is packed with the same strong flavour you’d find in a disposable, but in nicotine salt form, making them perfect for low-power pod kits and MTL tanks.

Instead of pre-mixed juice, you get a concentrated flavour base plus space to add your nic salt shots, so you can take it up to either 10mg or 20mg nicotine strength. This way, you control the nicotine strength and end up with smooth, flavour-packed e-liquid that’s just like your favourite bar salt, only mixed fresh in your own bottle.

Benefits of Switching To Longfills

The main reason to switch to bar salts longfills is that you won’t have to deal with 10ml bottles of vape juice anymore.

Find a flavour (or flavours) you like, buy them in longfill format and you won’t have to worry about buying any new e-liquid for weeks or even months.

I run three longfills at the same time: sweet tobacco, blueberry sour raspberry, and triple mango. These are my go-to flavours.

They usually last me around 2-3 months before I need to get refills.
This means I spend less on vape juice, always have plenty in supply, and I get that sweet, sweet bar salts flavour inside my pod vapes.

What’s The Best UK-Made Longfills Vape Juice?

There’s a lot of great vape juice brands in the UK, but far too many of the most popular e-liquid brands are manufactured in China and shipped over to the UK.

Think ElfLiq, SKE Crystal, and Lost Mary.

China doesn’t adhere to the same standards as the UK when it comes to vape juice ingredients, and this can be a problem. It’s why you hear of poeple having negative reactions to vape juice and things like popcorn lung.

At VapeBeat, we go a step further. All of our vape juice is designed, made, and manufacturered right here in the UK. We don’t just follow the rules, we exceed them.

That’s why our lab is fully ISO-certified:

How Bar Salt Longfills Work

Still unsure whether Bar Salt Longfills are for you? No worries. New stuff is always a little confusing. Here’s a quick breakdown on how they work, what they do, and how they can help you start saving money on your juice orders.

01

What Is a Longfill E Liquid and Why Should I Care?

A Longfill is a bottle that contains only concentrated flavour base—usually 60ml—leaving space for you to top it up with nicotine shots and/or VG to create a full bottle of ready-to-vape juice.

With our Longfill, you can easily mix up 120ml of e-liquid. It’s the perfect format for vapers who want disposable-style flavour, but in a refillable, cost-effective format.

02

Is a Longfill Better Value Than Buying Disposable Vapes?

Big time. With a Longfill, you’re getting the same bold, punchy flavour you’d expect from an Elf Bar—but instead of buying one device for a few hundred puffs, you’re getting up to 120ml of juice that works in any pod system.

That’s the equivalent of 8–10 disposables, all for a fraction of the cost—and with way less plastic waste.

03

What Do I Get With a Longfill Kit?

Each Longfill option gives you everything you need to mix at home. For example, our 120ml 10mg kit includes:

  • 60ml of concentrated flavour
  • 6 x 10ml Nicotine Salt Shots
  • Mix it all together and boom: 120ml of 10mg, 50VG/50PG vape juice.

Want 3mg or 0mg instead? There are kit options for that too—just pick what suits your nic level.

04

How Long Will a 120ml Longfill Last Me?

That depends on how much and how often you vape. For casual vapers using something like the Vaporesso XROS 5 or any low-wattage pod system, 120ml could last two to four weeks.

If you’re a chain-vaper, it might be closer to a week. Either way, it’s a solid stretch of vaping without constantly restocking.
