Lastly, you'll want to leave your VG and PG in a cool, dry, and dark place. Don't put in the fridge or freezer for long term, as it can introduce condensation when taken out. A bit cooler than room temp is best. And that should do you well!

How long does VG last?

The shelf life of PG (Propylene Glycol) is 2 years, while the shelf life of VG (Vegetable Glycerin) is 4 to 6 years. Flavours can last for up to one year, but PG and VG (which are preservatives) help the flavour last longer. The expiry date depends on the shelf life of the PG, so e-liquids last 2 years.

Does VG spoil?

Although both propylene glycol (PG) and vegetable glycerin (VG) are why the expiration date for vape juice is 1-2 years, most of the changes in vape liquid are due to the oxidation of the nicotine and the degradation of the flavorings. The effects of aging will vary from liquid to liquid.
