Does Vape Juice Go Bad or Expire?

When stored correctly your E-Juice should be good for approximately 2 years. However there are factors that influence the shelf life of your vape juice - whether premixed or a homemade DIY blend. The most common causes are nicotine oxidation and flavor degradation. 

What is nicotine oxidation?
Simply put, nicotine vape juices are best stored in a cool place away from direct sunlight. When left in direct sunlight, exposed to warmer temperatures/climates and/or the bottle remains open for too long you'll notice a harsher throat hit and/or very peppery aftertaste when vaping your juice.
What is Flavor Degradation?
This terms refers to the loss of flavor in your vape juice or DIY mix. You'll notice a slight change in flavor or a a slight chemical taste. If you are vaping a premixed nicotine based E-Juice, you will also detect a peppery taste and harsher throat hit due to the nicotine.
There are several ways to identify whether your E-Juice has expired:
  • Firstly you can take a look at the expiry date on the label.
  • Alternatively the batch number will also be a good indicator. If you suspect there is any issue with your vape juice reach out to the retailer and provide them with the batch number. 
  • Your juice may also appear darker than normal - this is due to the oxidation of the nicotine.
  • As mentioned watch out for a dull flavor and/or harsher throat hit. Or a chemical aftertaste.
  • Lastly, and not as common, your vape juice or DIY mix might have a bad smell.
