How should e-liquid be stored?
To keep your juice at its peak, treat it like a vampire: hide it from light and keep it cool. A dark cupboard works perfectly. If you leave it on your car dashboard in the middle of August, you’ll end up vaping a nasty soup that is anything but "fun."
Optimal storage is at a stable temperature between 15°C and 20°C, away from photons that break down nicotine molecules. Also, remember to tighten the cap to limit gas exchange, preserving the freshness of the aromas and the effectiveness of the nicotine over the long term.
