Once a collection grows to several bottles, how you keep them starts to matter. E-liquid carries no fixed expiry date, but the general view is that it tastes and performs as intended if used within about a year. Three things shorten that: heat, light and air. Here is how to keep each of them away from your different flavors.
What light and air do
Nicotine weakens under the sun’s UV rays and with too much oxygen. Oxygen reacts with nicotine to form cotinine. It is a slow chemical process, and the longer it runs, the less nicotine is left in the bottle.
What heat does
Warmth speeds up chemical breakdown in anything perishable, which is the reason food goes in the fridge. The hotter e-liquid gets, the more it breaks down, and the result is a noticeable change in flavor.
Where to keep your bottles
- Somewhere cool, dry and shaded. Pick a spot indoors out of the sun, and well clear of heaters, stoves and places where you often burn candles.
- A storage box. A box made for vape juice keeps bottles cool and dry, and some can be locked for safety.
- The refrigerator. This works, though you do not need it.
- The freezer. For long-term keeping, the freezer is an option. The liquid thickens slightly without freezing solid. Let it come back to room temperature before you use it.
- Never the car. Sun and heat inside a parked vehicle spoil juice fast. When you travel, carry the bottle with you.
Bottles, caps and labels
Tinted glass is the first choice for storage because it blocks sunlight and protects the flavor. Plastic is acceptable for the short term only.
Screw caps down firmly so extra air cannot get in. When only a small amount remains in a big bottle, decant it into a smaller one so less air sits above the liquid.
Write the purchase date on each bottle. If you rotate through many of them, the dates tell you which are oldest.
Storage is one part of it. We also have a guide to making your juice last longer.
In short
Keep e-liquid cool, dark and tightly sealed, and it will hold its flavor for longer. If you have questions, get in touch with us.
