New to the DIY world and so far it's been complete crash and burn in the flavor department. I have to go with 100% VG so I know this is part of the problem and also my taste buds are completely fried at the moment but I do manage to pick up at least some flavor from my store bought liquids. DIY so far have no flavor at all. (I did taste a tad bit of Blueberry in the Blueberry Cheesecake but honestly no flavor at all in the others) I'm using Nature's Flavors organics and apparently need to mix at a much higher level than expected. I keep adding, and adding, and adding. I'll mix, let steep for about two days, then test. Add flavor, repeat. Days later and I still don't have one I can use. They smell terrific but completely lack flavor. How high % should I go with my flavors or am I just using the wrong brand? So far I'm at about 10% to 12% but really it's difficult to be exact because I add more flavor to the bottle after I've removed a sample which raises the final percentage. Can anyone assist a failing but persistent noob?
