How to Store Vape Juice: 3 Do’s and Don’ts of Vape Juice Storage

Throughout your vaping experience, you’ve probably noticed that e-liquid can be an expensive part of the hobby. 

This has led some vapers to follow the DIY juice route, creating their own flavors at home instead of buying ready-made juices. Other vapers combat the standard price of e-juice by buying bulk during sales, purchasing enough to keep them going until the next special rolls around.

Whatever the cause, you’ve probably found yourself in a position where you have a lot of e-liquid but aren’t going through it quite fast enough. After all, 100ml bottles hold a lot of juice and can take quite some time to finish.  

Fortunately, e-liquid can last a long time if you avoid its three enemies, and it can last even longer if you combine it with the 3 ‘friends’ of vape juice storage.  

In this article, we’ll be looking at the top three do’s and don’ts of storing your excess vape juice, so that you never have to come back to a sour-smelling (and tasting) e-liquid.

The 3 Enemies of E-Liquid – The Don’ts

While the propylene glycol (PG) base of your vape juice is resistant to deterioration, the vegetable glycerin (VG) and nicotine are both organic compounds that will go through changes as time goes on.  These changes, which affect the taste and smell of your liquid, can be sped up by three things:

1. Heat

If you remember anything from high school chemistry, you’ll know that the more energy a molecule has, the more likely it will undergo a change or breakdown. This principle is definitely true with your stored vape juice.  

If you’re storing your e-liquid in a warm place (like close to an oven or heater) the chemicals inside will change quicker, leaving you with a sour, probably unusable, e-juice. Hence, don’t place your vape juice where it’s hot.

2. Air 

Oxygen easily reacts with the nicotine in your e-liquid. This process (called ‘oxidation’) will break your nicotine down into cotinine.  

Cotinine turns your liquid brown and affects the flavor, even though it will still have the effect of nicotine. However, flavors will deteriorate faster than your nicotine, especially tobacco and coffee which go through changes quicker and easier than other flavors.

To avoid this, don’t leave your vape juice with a loose cap or totally uncapped.

3. Light

Just like heat, UV light can help the process of oxidation go faster by feeding energy into the reaction.  Direct sunlight and certain artificial lights are all sources of UV light that will ruin your e-juice before you get a chance to savor it.

Therefore, don’t expose your vape juice to direct sunlight and other light sources.

Knowing these three don’ts of storing your vape juice, you might have already noticed some mistakes you’ve been making and you can hopefully avoid them with that next flavor you want to hold onto.  

Now, there are some things that will help you keep your vape juice as long as you’d like—even past the expiration date!

The 3 Friends of Vape Juice Storage – The Do’s

You’ll be happy to hear that not everything is trying to ‘attack’ your vape juice. Now that you’re acquainted with the three things that harm your e-liquid, let’s take a look at the three things that will help your juice hold longer than it ever has before:

1. Right Storage Place

As you’ve probably noticed above, where you store your vape juice can make a huge difference. 

A place that’s hot and exposed to sunlight is definitely not one of them, so what is?  Well, the exact opposite. 

Storing your vape juice in a cool, dark place, like the back of your closet or under your bed, will keep the energy of the molecules low. This means that the chemical reactions will take much longer to happen, keeping your vape juice from going off.  

If you want the best storage space, however, pop your bottle of e-liquid into the fridge or freezer.  The low freezing point of VG and PG will prevent your juice from freezing into a solid while keeping your e-juice fresh and ready to use.

2. Right Bottle

Most e-liquid manufacturers use either glass or plastic bottles.  

Plastic bottles are not the greatest for long term storage because plastic can interact with your liquid (especially in heat) and change the taste, disappointing you when you finally get around to using it.  On top of this, although plastic keeps most things out, it still lets some air pass through into your bottle—no matter how well you seal it.  

For anything other than short term storage, make sure you’re using glass bottles to hold your e-liquid.  Glass won’t let anything into the bottle and will keep your e-juice as tasty as the day you bought it.

3. Properly Sealed Bottle

When storing vape juice, it’s important to keep as much air out of the bottle as possible. This includes the leftover air inside your bottle.  

If you’re not storing a full bottle of e-liquid, it might be a better idea to swap over to smaller bottles.  Smaller bottles will also make it easier when you want to start using the e-juice since you can take them out of storage one at a time instead of taking out the big bottle and risking a deteriorated flavor.  

Make sure that you avoid as much air as possible when swapping your e-liquid from one bottle to another.


If you pay attention to these do’s and don’ts of vape juice storage, you’ll find yourself with bottles of e-liquid that have been stored for months, if not years. These factors are all easy to control and, apart from perhaps buying glass bottles, won’t cost you an extra cent on top of your already pricey e-liquid.

To summarize these tips:

  • For short term storage: If you’re looking to store your e-liquid for a few months, you can use plastic bottles to keep your juice in a cool, dark place. The back of your closet or under your bed should work perfectly well.
  • For long term storage: If you’re planning on storing your e-juice for longer (like a number of years), a glass bottle inside your refrigerator or freezer is by far the best way to go. This will keep your juice deliciously fresh for as long as you need.

Some other things you’ll want to keep in mind is that certain flavors, such as tobacco or coffee, will deteriorate faster than others. Also, if you have kids or pets, you’ll want to make sure your storage spot is well out of reach of the wrong hands.
