I recently got a deal on 500 ml bottles of cotton candy e-juice, I've put 500ml into a glass mason jar, wrapped in newspaper in my refrigerator, I was told it had a shelf life of 1 year but if kept in a cool dark place in glass it would be good for years. Does anyone have experience storing it and know how long it stays good. I don't want to overbuy and have the juice go bad before I can vape it. Any help or advice would be appreciated
