So I was just wondering... Can juice go bad?? I've been vaping up all of my older juice to bring in the new and I was just curious if there would be a shelf life on it. I know most people say that it gets better, the more it's steeped, and I do agree with that. As far as I can see, I brought out a juice today that is about a year old now and it seems to still have good flavor. Well, I was just curious to see if anyone would have some feedback on this.
