50/50 Shortfills: E-liquid Guide

Vaping continues to evolve as trends come and go, offering more and more ways to customize our experience so that every vaper out there can find utter satisfaction through their hobby. One of the latest trends in the vaping marketplace is shortfill e-liquid, which serves the unique purpose of allowing vapers to add their own nicotine shots to an otherwise pre-made bottle of vape juice. Today, we’ll dive into this new and innovative vape formula that has been a godsend to many enthusiasts around the world.

What are 50/50 Shortfills?

50/50 shortfills are a type of e-juice formula that typically comes in 50ml or so bottles and is filled only about 90% of the way—hence the name “short fill.” They have a 50/50 VG/PG ratio, which makes them compatible with those who use MTL vaping systems. A 50/50 VG/PG ratio is generally associated with vapers craving more of a throat hit and who use lower-wattage devices like pod systems.

Shortfills were developed as a workaround to new regulations from the Tobacco Products Directive (TPD), which limited the amount of nicotine that could legally be in an e-liquidShortfills are designed for vapers in the European Union to legally purchase vape juice formulas and add nicotine themselves. The remaining 10% space in the bottle is specifically for adding liquid nicotine, while the standard ingredients like VG, PG, and flavoring are already included.

Understanding the Composition

Shortfills contain flavoring ingredients, vegetable glycerin (VG), and propylene glycol (PG); the only ingredient they lack is nicotine. The flavoring is typically more concentrated than in a standard e-juice bottle because the user adds nicotine, which dilutes the flavor.

How 50/50 Shortfills Differ from Other E-Liquids

Again, 50/50 shortfill e-liquids are simply vape juices that are missing the nicotine, which is meant to be added by the user after purchase. There’s enough space in the bottle between the top and the cap for the user to add the appropriate amount of nicotine to the formula.

Benefits of Using 50/50 Shortfills

50/50 shortfills allow residents of the European Union to purchase and enjoy bottled vape juices legally. However, their benefits extend beyond legality, which is why they’re becoming popular worldwide.

Balanced Flavor and Vapor Production

Shortfills allow vapers to experiment with their formula by adjusting the nicotine level. The 50/50 VG/PG ratio is ideal for MTL vapers, offering a balance between flavor, vapor production, and throat hit. Higher VG ratios, primarily used for DL vaping, produce massive clouds but may limit throat hit and flavor.

Versatility for Different Vaping Devices

A 50/50 vape juice ratio is more versatile, as it can accommodate more vaping devices and output levels (wattage, temperature, etc.). It’s compatible with both pod systems and sub-ohm systems.

How to Choose the Right 50/50 Shortfill

Now, if you’re ready to buy a 50/50 shortfill vape bottle, you still need to consider a few factors to ensure you get the right one. Despite the formula being straightforward enough, a couple of variables can greatly affect your vaping experience.

Consider Your Nicotine Preferences

First, consider the type of nicotine you want. 50/50 shortfills are compatible with both salt nic and freebase nic, and the choice is yours. While it's standard to add enough nicotine to fill the bottle, some users may decide to add less for various reasons.

Flavor Profiles to Match Your Taste

Of course, you’ll also want to consider the flavor profile of the shortfill, just like you would with any other vape bottles. Explore the variety of shortfills being sold online or at your local vape shop, and then choose the flavor that best suits your personal tastes.

How Do 50/50 Shortfills Compare to 70/30 Shortfills?

You’ll find two standard shortfill formulas: 50/50 and 70/30. The latter is mainly compatible with box mod systems. A 70/30 VG to PG ratio, with its higher vegetable glycerin concentration, allows for cloud-chasing due to its thicker consistency. On the other hand, 50/50 shortfills are ideal for MTL vaping and can accommodate a wider range of vaping systems and power output levels.

Common Questions About 50/50 Shortfills

Are 50/50 Shortfills Suitable for Beginners?

50/50 shortfills can accommodate beginners, as the method of adding nicotine shots to a bottle is quite simple. 

How Can You Store Your E-Liquids Properly?

All vape juices benefit from being stored in a dark, dry, and cool place with the lid tightly on to prevent oxygen from entering. Vape juices should typically be used within 12 months to ensure the flavor remains fresh.

Troubleshooting Common Issues

Lastly, let’s talk about a couple of common issues you may run into when using shortfills.

Fixing Throat Hit Problems

Addressing Leaking and Spitback

Spitback and leaking aren’t issues unique to shortfills. They often indicate that the coil in your cartridge or tank needs replacement. Alternatively, you might be hitting your device too hard, drawing liquid into the mouthpiece before it properly vaporizes from the heat of the coil.

Bottled vapes have evolved significantly over the years, and 50/50 shortfills stand out as one of the most unique innovations. These formulas serve a specific legal purpose while also offering numerous advantages that have fueled their popularity, even in regions with less vaping restrictions. The takeaway is that 50/50 shortfills represent more than just a passing trend in the industry.
