Thanks Andria, I did double the VG/PG Nic mixture and added it to the original brew. Unfortunately I'm new at DIY and I'm learning quickly that I shouldn't make 50ml batches when I'm concocting new recipes. I've got little mason jars of steeping juice all over my desk.
I did learn quickly the strength of Walmart's Good Value Stevia, which I put in with TFA Kentucky Bourbon, it's sweet but still vapable. I guess it's a learning process just like cooking, that's what I love about this new phase of vaping for me.
Yes it really is a lot like cooking, developing new recipes, learning what brands suit you best for any given flavor. When I first started, I would make test batches at 10ml, but I've had so many screaming failures, I now don't try anything new in anything larger than 5ml -- saves a lot of waste!
Since you're just starting with DIY, you might want to try the "High Flavor Mix" technique, just because you can get a really good idea of how something will taste right at the time of mixing, not have to wait around for weeks just to find out that a recipe didn't work and have to start over -- if you use 25%-30% total flavoring (for anything NOT a tobacco flavor!), you can usually tell right away if something is even worth steeping, or you should just start over. With high percentages, usually the steep time is in hours or just a few days, rather than weeks, but you know right away if it's even worth waiting those hours or days.
Tobacco flavors aren't suited for the HFM mixing; with tobacco, sometimes .5% can mean the diff between tolerable and godawful, and tobacco flavors nearly always require a long steep to let the flavor fully develop. I've got an iteration of a cherry-vanilla pipe tobacco that I've been waiting on for a bit over 3 wks; tasted it yesterday, and it's not as good as the first version I mixed, but maybe it just needs more time -- I'll give it a couple more weeks before I toss it.
Check out the Flavor Apprentice thread; lots of absolutely genius mixers in there, lots of recipes and great tips, and more info about the HFM technique.
