E-juice shelf life is generally cited as having a shelf life of one to one and a half years, but there is a fair amount of uncertainty on this topic. If you store your e-liquid properly, it can have a shelf life of up to two years.

The estimate for the e-juice expiration date is primarily based on the established shelf lives of PG and VG, with nicotine being capable of being stored indefinitely in proper conditions. The uncertainty comes primarily from the flavorings, which can vary from liquid-to-liquid. For Black Note, all of our flavors are naturally-extracted from tobacco (and peppermint, for Solo), and we don’t add any flavorings or colorings, but overall the same considerations apply to any e-liquid.
