What are the pros and cons of e-liquid refrigeration?

There are many vapers that keep their e-liquids in the refrigerator. The biggest reason for this is because it's believed that refrigeration expands the lifespan of the e-juice. Another reason is that keeping it in a closed space, like the refrigerator, will help keep air out. This will also help the flavor be more intense. With everything, though, there are some pros and cons to keeping your e-liquids in the refrigerator. 

Pros

• It will help extend the lifespan of your vape juice(s).
• The flavor will be more intense since it won't have much air getting into it
• You don't need to worry about bacteria.

Cons

• Going from refrigerator temperature to room temperature, and vise-versa constantly can make your juices go bad.
• Liquids that are kept in the refrigerator for long periods may have side effects, such as: headaches, jitteriness, and an unpleasant aftertaste.
• Liquids that have high PG will become unpalatable.
• Liquids stored in plastic inside the refrigerator will expire faster due to osmosis.
• Bottles that are emptier i.e. have more space between the top and the juice will go bad quicker than bottles that are fuller.

Refrigeration is a short-term solution as keeping your juices in a refrigerator for long periods of time can decrease their shelf life. If you do store bottles in a refrigerator do so for as little time as possible, ensure that they are pretty much full and make sure that they are stored in something other than plastic. A good alternative to plastic are glass amber bottles. This will keep any light out and they’re more airtight than plastic bottles.

Remember, if you don't have to put your bottles of e-liquids in the refrigerator then you shouldn’t as you want to keep them fresh for as long as you can.
