E-Liquid Expiration - What You Need to Know About It

E-juice or e-liquid is said to be the heart of a vape. For the uninitiated, it is the substance used to evaporate the liquid within the atomizer to give you an uplifting vaping experience. It usually consists of propylene glycol (PG) and vegetable glycerol (VG) as a base, some flavourings, and nicotine solution. There is a wide array of e-juice flavours to explore in the market these days – from traditional tobacco e-juice to fruity flavours down to menthol e-liquid––choices are unlimited.

As far as e-juice is concerned, one of the frequently asked questions is regarding the length of life of the e-liquid. In this article, we’ll cover the expiration of the e-liquid, proper storage tips, and signs of a spoiled e-juice.

Duration of e-liquid

As far as the expiration of e-liquid is concerned, there’s no standard date established. However, the general consensus is that most vape juices will last between one to two years. Of course, you have to factor in the following:

  • Flavouring: Know that added flavouring can cause the vape juice to be steep. This means that the flavour matures over time, much like wine. If left unused for quite a while, this flavour may become stronger and leave an unpleasant taste. This makes flavouring the most vital factor that can determine the shelf-life of an e-liquid.
  • Nicotine content: The nicotine content present determines the longevity of an e-liquid. The more concentrated it is, the more it can last.
  • PG or VG content: The e-liquid shelf life can also be affected by the quality of its ingredients, whether propylene glycol (PG) or vegetable glycerin (VG) present in it.

Proper storage of vape juice

There are a few steps you can take to make sure that the e-juice will last for as long as possible. It all boils down to the proper storage of your vape juice. Consider the following steps:

  • Ensure that the receptacle of the e-liquid is sealed. This is to prevent air and bacteria from reaching the juice and spoiling it.
  • Store the e-liquid in a suitable place that’s away from the sunlight. Know that light exposure can affect nicotine and flavouring.
  • Make sure the e-liquid is kept in a place with the right temperature. Heat can make your vape juice thinner and return to normal when it cools. On the other hand, storing your vape juice in the fridge can add moisture and risk microbiological contamination.

Signs of a spoiled vape juice

If you want to know whether or not your vape juice has gone bad, there are a few signs that indicate such instances. Here are some of them:

  • Colour - check if it’s too dark.
  • Smell - see if it smells stronger than usual.
  • Split - examine if the ingredients in your e-liquid have split or separated from each other.

If you notice one or all of the above, do not use the vape juice and dispose of it right away.


The e-liquid in vaping won’t necessarily cause serious harm to vapers as compared to the chemicals found in cigarette smoking. As a rule of thumb, however, it’s best to throw the vape juice away if you’re unsure of whether or not it’s safe for consumption.
