Longfill E-Liquids

Tired of tiny bottles and fixed nicotine levels?

Let’s be real: buying 10ml bottles every other day is a drag. Not only is it bad for your wallet, but it also limits your freedom. If you've been vaping for a while, you've probably felt the frustration of TPD regulations capping your bottle size if it contains nicotine. Or maybe you're stepping up from 600-800 Puff Disposable Vapes and want something more sustainable and customizable.

The problem with standard e-liquids is the lack of flexibility. You're stuck with the manufacturer's PG/VG ratio and specific nicotine strengths. But what if you want a specific throat hit or massive clouds without compromising on flavor? That's where the Longfill format comes in to save the day. It puts the chemistry set in your hands (without the danger), giving you the freedom to create a massive 60ml supply of your favorite juice exactly how you like it.

Don't mess it up: Common mistakes with Longfills

Jumping into the DIY mixing world is exciting, but I've seen plenty of vapers ruin a good bottle by rushing it. The biggest mistake? Vaping the concentrate straight out of the bottle. Seriously, don't do that. Longfills contain highly concentrated aroma (usually 10ml to 20ml in a 60ml bottle), and they are not ready to vape. It will taste harsh and could ruin your Vape Coils in seconds.

Another classic blunder is confusing Longfills with Shortfills. While they look similar, Longfills have much more empty space and a stronger concentration of aroma, meaning you need to add more base or nicokits to fill them up. If you treat a Longfill like a Shortfill and only add one nicokit, the flavor will be overpowering and the viscosity might be off for your device.

Master the mix: How to prepare your Longfill like a pro

Getting the perfect mix is easier than it sounds. Think of a Longfill as a flavor shot waiting for the main ingredients. Here is the cheat sheet to get it right from the start:

• Check the capacity: Most Longfills come in a 60ml bottle with about 16ml of aroma (like the Drops range). This leaves you roughly 44ml of space to play with.
• Choose your base: Decide if you want more flavor and throat hit (higher PG) or bigger clouds (higher VG). Make sure your device, whether it's a pod or a powerful Smok Vape, can handle the density you choose.
• Add Nicotine (or not): This is the best part. You can add multiple nicokits to reach higher strengths (like 6mg or even higher) that Shortfills can't handle. If you vape 0mg, just fill the rest with nicotine-free base.
• Shake and Wait: Once you've filled the bottle, shake it like you mean it. While some are good to go instantly, giving it a little time to steep lets the flavors bind perfectly with the base.

Why Longfills are the ultimate upgrade for your vape

Switching to Longfills isn't just about feeling like a chemist; it's about quality and economy. Because you are buying the aroma and base separately, the cost per ml drops significantly compared to finished liquids. Plus, you get access to premium flavors—like the legendary Route 66 or Faustos Deal—in a format that lasts much longer.

This format allows you to fine-tune your experience. If you need a specific nicotine hit that isn't standard (say, 4.5mg), you can achieve it here. It’s the perfect bridge between buying ready-made juice and full-blown DIY alchemy. You get the convenience of a pre-measured flavor profile with the flexibility of a custom mix.

Frequently Asked Questions about Longfill E-Liquids

What is the difference between Longfill and Shortfill?

The main difference is the amount of aroma and empty space. Shortfills are almost full (e.g., 50ml in a 60ml bottle) and only have room for one nicokit, usually resulting in max 3mg nicotine. Longfills have much less liquid (concentrated aroma) and more space, allowing you to add multiple nicokits to reach higher nicotine strengths.

Do I need to buy a separate base?

Yes, or at least nicokits. You cannot vape the Longfill as is. You must fill the remaining space in the bottle with either neutral base (PG/VG) or nicotine shots (nicokits) to dilute the aroma to the correct level.

How long should I let a Longfill steep?

It depends on the flavor profile. Fruits are often shake-and-vape, meaning they are good to go almost immediately. Dessert or tobacco flavors often benefit from resting for a few days to let the nuances develop fully.

Can I use Longfills in any device?

Absolutely, as long as you mix the base correctly. If you use a high VG base, you'll need a sub-ohm device. If you mix it 50/50, it will work perfectly in smaller pods or starter kits.
