Well, it was alot of trial and error like baking, but to save time, there is a online repository of recipes that people share online. What i liked to do was see what people said what % of what flavour tasted like, and note this down to see what i could get from other flavours. My most favorite flavor i made was a apple fritter that tasted like jelly apple pieces in it. of course i am making very small bottles of this not to waste material, then i would try it out on a RDA(rebuildable dripping atomizer). usually small amounts people make for personal use are made by weight, but the big companies measure by volume as its much easier when bottling 1000s of bottles.
