Not every bottle of e-liquid has a listed expiration date, and even when it does, you’re probably curious as to how long you can hang onto that bottle of extra juice. Stocking up on e-liquid is something that a lot of vapers do. It’s great to know that you have bottles on back up in case you run out of your favorite flavor. Keeping multiple bottles on hand is a great tip for regular vapers, but only if you properly store the bottles that you aren’t using right away. Unfortunately, e-liquid doesn’t stay good forever, and there is a typical shelf-life.

How Long is E-Liquid Okay to Vape?

Luckily for you juice hoarders out there, the shelf-life of most e-liquids is about two years. You’re probably wondering why. Nicotine, propylene glycol (PG), and vegetable glycerin (VG) are all main ingredients of your juice. If these ingredients are exposed to certain conditions they will degrade sooner than the two-year shelf-life. Flavoring also degrades over time, especially when exposed to the elements.

How Can I Get the Most Shelf-Life Out of My E-Liquid?

Want to get the most out of your money? Store your extra bottles of e-liquid in a cool, dry area away from the sunlight. The elements that are going to affect the quality of your juice are excessive heat, sunlight, and air. That’s why the best place to store your extra bottles of e-liquid is somewhere tucked away safely from all of the harmful elements, like a drawer or a box.

The heat issue is a prevalent one with vapers who like to take multiple bottles of juice along with them. It’s super easy to forget and leave a bottle of juice inside of your car. Or if you’re like me, you may forget about the extra bottle you’re toting around in your bag. Just remember that prolonged exposure to heat and light is going to alter the quality of your e-liquid, so it’s best to take care of the bottles you keep on hand, as well as the extra ones you keep at home.

How Do I Know if My E-Liquid is Going Bad?

There are a few indicators of degradation in your e-liquid. These are all pretty noticeable, but the first thing you’ll probably see is color change (from oxidation) or a change of flavor. You might also notice that the juice is separating slightly, the nicotine strength doesn’t seem up to par, or your juice is a thinner consistency. Light, heat, and air can alter all of these qualities. If you notice one of these changes, your e-juice is probably on the way out.

Whether or not you decide it’s time to toss a bottle of e-liquid out is on you, but I personally think it’s better safe than sorry. When in doubt, throw it out! It’s not really worth it to vape juice that is expiring. Or to save your e-liquid from kicking the bucket too early, store it properly.
