Well I thought I would try to mix my own juice. I ordered 3 small sample size drops of Butter Cream,Bavarian Cream and Vanilla Bean Ice Cream. They read concentrate. I don't even know if i ordered the right stuff to try. Have I screwed up already by buying these drops. I was just going to start out to try to make a simple vanilla flavor. I bought all the gear and can mix by weight. Found some calculators. Have I messed up or what? Can I use the these flavor drops? The Capella site didn't address this. Thanks
