There are a lot of options as you look for a vaporizer. Different styles and types and makers like Storz and Bickel. To be considered alongside that is what vape juices you might want to explore. A frequent question about e-liquids is whether they can go bad. While they are meant to be shelf stable the fact is it is a case that the sooner you use them the better. The expiration date given assumes you take the proper steps to store the vape juice in optimal conditions. If you are just a casual user you would be better off not buying in large amounts and the same is true if you are not taking those extra steps for the best storage. Usually, the life of the juice affects the quality of it. When it comes to flavourings they can diminish over time, and there are lower-quality liquids that degrade more quickly.
Consider what the juice looks like
Vape juice that is healthy is going to have a consistency and appearance that are uniform. With an older juice you might can see changes in texture and separation with the liquid itself. You might see oils separating creating different levels in the liquid and sometimes they might gel together so that some small solid bits appear. If you look at e-liquids for your Mighty Vaporizer or whatever type you have, you can compare them and likely spot the ones that are healthier than the older ones. Those changes indicate that the liquid is close to its expiration date. Some juices also turn a browner color as they age. This is a normal process, it does not mean the vape juice is bad. But it indicates aging.
Next check out the smell and taste
Then there are the taste and smell tests. These can be a little more subjective, an experienced vaper is going to do better at this than someone new to vaping. Consider how concentrated the flavor is. While some feel that vape juice ages and develops flavor, there is a point where the flavor is negatively impacted by its age. When a vaper with their Storz and Bickel device feel like the flavor is not as strong that is a sign it is close to or past its expiration date. Old e-liquids can also smell bad as the compounds in it start to breakdown. If it has nicotine in it then the strength of that is reduced as well.
There is not a lot to be found on the topic other than what has just been stated. Enjoy your Mighty Vaporizer and just use your senses when buying your vape juice. The more consumers demand better quality in their vape juices, the more chance they have of getting expired e-liquids off the shelves. While very old vape juices might still be safe to use that does not mean they are going to give you the best experience. Check the packaging and have more awareness of what healthy liquids look like compared to ones that are aging or expired.
