Just posted this in another thread, but I'll go into a little more detail. First, I never do the whole caps off thing. I did that when I started vaping, but I've now found the best method is time. I don't manically shake my juices daily either. I've learned maybe once a week (if I think about it), but sometimes I don't even do that. As the saying goes, time takes time. I always suggest people order months in advance because you can just keep a steady rotation of juices. You could always buy a dripper and test it. In my experience, if they don't taste good after 3 months, they aren't going to taste good ever. Then it goes into the "give it away" pile.
