If you have a nice stock of juice and you can put a bottle up for 2-3 months or more should you bother with taking the cap off it or shaking it or just throw it on the shelf? I've still been letting mine breath when I first get them and shake them up usually once a week at least but I wonder if I'm just wasting time? I usually try to use them by date using the oldest first so I think some might reach nearly a year in age before I vape them.
