Patience is everything with DIY. I found the recipe I love, and I make large batches and stay at least a month ahead. I do mostly tobacco flavors, and the flavor changes dramatically with age. I have recently started mixing fruit liquids for a friend who likes them, and I noticed that those come together rather quickly. I discovered I really like Dragons Blood.You can try speed steeping with hot water, but I find that the slow method makes for a better product. Leave.the bottles uncapped for a day, also. This will allow any alcohol that may be in the flavoring to evaporate. For sweetening, I like to use vanilla, maple, or caramel. I rarely use EM or other sweeteners, on the advice I got from this forum. They can mute flavors, and leave you with flat tasting juice. Also do single flavors, so you can find out what each component tastes like. Have fun and experiment. Good luck!
