I know I mixed some of my own, my first thought was that it was un-vapable, absolutely disgusting. Even though I had carefully read and understood what quantities to use and in my opinion was dealing with high quality ingredients. I thought there must be some secret techniques of the juice makers that allowed them to sell juice that actually tasted good. But that didn't really make sense. So I read some more,found out about steeping. I tossed my DIY juice into a cup of near boiling water, let it cool, then tossed it on a closet shelf for a cople of days. Result? Perfectly excellent juice,I'm vaping it right now. Was that the best technique? I don't know,it's just what I did. But the difference between this and what it was freshly made, there is no comparison. I also agree that if I pay retail for ready to go juice,it should be ready to go.
