Up in Smoke: All of the Basics on an E-liquid’s Shelf Life

Every vaping enthusiast is very much familiar with their e-liquids, owing to the fact that it is where they get their vapours from. Without it, their sessions would be tasteless and boring overall. That being said, it is only fitting for everyone to familiarise themselves with the shelf life of e-liquids so that they would be able to use them to their fullest.

Below are just some helpful tidbits that may help them do that.

The Average Shelf Life of an E-liquid

It is not to everyone’s knowledge that the shelf life of e-liquid is actually dependent on the e-liquid itself, as well as the specifications of the container that they are kept in. While they may have the same overall expiration, the difference will be seen in the conditions that they are kept in.

As a rule of thumb, the average shelf life of an e-liquid ranges between one and two years. However, this is still dependent on the brand, as well as the storage.

Conditions of Storage

The e-liquid’s shelf life is affected by the storage area that they are kept in. If they are kept in a place that is hot, wet, and with direct exposure to light, it may wear off the flavours and change the amount of nicotine that is in the e-liquid. This might also affect how it tastes and the vapours that it produces.

If you are going to store your e-liquids, make sure that you keep them somewhere that is cool, dry and out of direct sunlight. The best place for them is in your refrigerator. However, make sure to take out the e-liquids that you are going to use regularly and store them somewhere else closer to the e-cig.

If you are going to keep the e-liquids in your freezer, it is absolutely essential to have them in a tightly sealed container. Otherwise, it would be contrary to the nature of freezing, which is to preserve. Instead, the vapour will very likely be spoiled.

What Happens When E-liquid Degrades?

When e-liquid starts to degrade, it is sure to be apparent in several ways. The most notable of these is its change in taste, which could be distinctively sour or bitter. The flavour might also become less consistent and may even change at random. When this happens, the e-liquid is not good anymore, and you shouldn’t vape it.

Another sign of e-liquid’s spoilage is its colour. If it begins to change from its original hue and becomes a darker shade, or even a colour that has no resemblance to the original colour, again, it means that it is no longer safe to vape.

If you spot any of these signs, you might want to consider throwing them away. Contrary to the normal expectation of keeping the e-liquids, the benefits of keeping them are just not worth it.

Nicotine Strength Affecting an E-liquid’s Shelf Life

Nicotine, which is believed to have a half-life of one day, actually works a little differently than what most people think. Most vapers believe that nicotine degrades quickly; however, this is not really the case.

Contrary to popular belief, nicotine is actually quite stable when kept in proper conditions. While it is true that it does degrade over time, it does not happen all at once.

If you want to get the most out of your e-liquids, you should find out their nicotine strength. The higher the level of nicotine, the shorter the shelf life of the e-liquid.


The shelf life of e-liquids is not something that is often talked about. Most vaping enthusiasts are only concerned with vaping the e-liquid, not when it is actually safe to vape it.

However, knowing the lifespan of your e-liquids is an important factor in getting more out of them and is an essential part of vaping. After all, we could never make the most of it if we didn’t know when to use it.
