Ejuice has 4 basic parts: PG, VG, Nicotine and Flavor(s). The purpose of the PG is to carry the flavor-- it's good at that; 1/3 or more of most commercially prepared sauces is PG-- and to thin the VG so it will wick well; PG also provides some throat hit if not as much as nicotine. The VG has a slightly sweet taste by itself, and it's what makes the fluffy while cloud when you exhale. The Nic should be obvious, and the flavors are where the taste comes from. I suggest you start at a 50/50 PG/VG ratio just to begin. If it's too harsh or you're getting no cloud, bias toward VG. Not enough throat hit or the flavor is muted, or the VG makes you cough or gives you phlegm, bias toward VG. One good way to get started is to purchase a starter kit, but you don't have to. You will need something to measure with and mix in. For small batches, 10ml syringes will do to measure; a small glass tumbler and a stainless spoon will get the rest of it done. (Mark the nic syringe-- red fingernail polish works) and use it only for that.) If you don't want to go the starter kit route, let me suggest you pick a real simple flavor, like peppermint. I mention this because one of my standard flavors is peppermint. Buy a minimum quantity of PG and VG and Nic juice, plus a small bottle of peppermint flavor and sweetener. Then using a juice calculator--
this is the one I use-- plug in your PG/VG ratio and the MG of nic you want, plus how much in total you wish to make. Start small, no more than 10 or 15 ml per batch until you get a recipe you like. You'll have to tell the calculator the bases in the nic juice and flavors; this is usually PG, but nic can be bought in VG or a PG/VG mix as well. Whatever it is, just plug it in. The place you buy them will tell you what the bases are when you order; frequently you can select it. The calculator will then tell you how much of each ingredient to add. Dump them in the glass and stir, or in a clean used juice bottle and shake. A good ratio to start is something like 12% peppermint, 3% sweetener. I take mine stiffer, I use 18/8, but that's very strong. Note that ejuice is best when you allow it to steep some before vaping. A couple days in the dark, shaking once or twice a day, is a big improvement. That's really for later though, you'll want to try it right away I'm sure. Finally, while there are many quality vendors, and some fly-by-nights, I buy my nic juice from
MyFreedomSmokes and my flavors from
