Storing your e-juice properly is key if you want to maintain its quality and flavour for as long as possible.
Why proper storage matters
E-juice contains ingredients that are sensitive to heat, light and air. Exposure to these elements can degrade nicotine and vegetable glycerin (VG), impacting both flavour and quality.
Avoid heat, light & air
Temperature: Heat is one of the biggest enemies of e-juice. When exposed to high temperatures, the composition of the liquid can change, which in turn affects flavour.
Store e-juice in a cool place; room temperature is usually acceptable, but a cooler cupboard or dark place is even better.
Light & air: Exposure to light and oxygen accelerates oxidation in nicotine, which may change the colour of the e-juice and diminish the flavour.
Keep bottles sealed when not in use to minimise air contact.
Recommended storage places & containers
Dark cupboard or pantry: A great choice for storing e-juice for moderate periods.
Refrigerator: If you expect to store e-juice for a long time, the fridge is a good option. However, if the VG content is very high, the liquid may thicken when cold — let it return to room temperature before use.
Freezer: It is possible, but not always ideal — some users have noted flavour loss when using the freezer. The higher the VG percentage (>80 %), the greater the risk it will partially freeze.
Container material: Glass (especially dark or amber-tinted) is best for long-term storage; plastic can be adequate for shorter-term use but may interact with the liquid over time.
Key practical tips
Always keep the bottle tightly closed when not in use. More air in the bottle = faster degradation.
Store the bottle in a place away from direct sunlight and heat sources (e.g., away from radiators, windows, the car in summer).
If a bottle looks drastically darker than when you first bought it, or smells/tastes odd, it might be a sign of oxidation or other deterioration.
Summary
To keep your e-juice fresh and maintain flavour: store it in a cool, dark place; keep it sealed; prefer glass for long-term storage; and check it if it’s been a long time since purchase. If you notice odd taste, colour or smell, it’s safer to discard it and get a fresh bottle.
