I am new to making juice. So far I have tried Lorann flavorings and they seem to be strong flavors but a lot of food colorings made them vape awkward. Recently, I got about 15 different flavors from Flavors apprentice. The flavors are challenging me to find the right percentages. I read the forums on each and it says many people are using 15 -20% flavor. I have been trying and it seems like anytime I use over 10% there is a strong alcohol taste and it burns throat. When i use less it seems to not be flavorful. Does anyone have any suggestions to counteract the strong alcohol taste and burn? Or is there an updated chart with percentages?
